In addition to angiogenesis and neurogenesis, cell- and pharmacologically based therapies substantially remodel white matter in the ischemic brain. Treatment of experimental stroke with MCSs, rhEPO, or sildenafil significantly increases axonal density encapsulating the ischemic lesion. Dynamic changes of white matter structure along the ischemic boundary have been imaged in living animals by diffusion tensor imaging (DTI) and fractional anisotropy (FA) measurements. Data from these MRI indices demonstrate that administration of rhEPO or sildenafil augments axonal remodeling and angiogenesis and that both of them are spatially and temporally correlated. Administration of MSCs, rhEPO, and thymosin beta 4 (Tβ4) dramatically increases the number of oligodendrocyte progenitor cells in the corpus callosum, the striatum, and the V/SVZ of the ischemic hemisphere and mature oligodendrocytes in the ischemic boundary adjacent to myelinated axons. These findings suggest that cell- and pharmacologically based therapies promote generation of oligodendrocyte progenitor cells in the ischemic brain that migrate to target axons, where they extend their processes myelinating the axons.
Tβ4 is a multifunctional regenerative small peptide containing 43-amino acids, and it is the major G-actin-sequestering molecule in eukaryotic cells.21 Tβ4 has pro-survival and pro-angiogenic properties, protects tissue against damage, and promotes tissue regeneration.22,23 It also plays a key role in corneal, epidermal and cardiac wound healing.21 Tβ4 participates in axonal path-finding, neurite formation, cell proliferation, and neuronal survival.24-26 Our previous studies show that Tβ4 reduces inflammation and stimulates remyelination and improves functional recovery in animal models of experimental autoimmune encephalomyelitis (EAE) and stroke.25,27 In summary, these pleiotropic properties make Tβ4 an ideal candidate for treatment of TBI.
Thymosin Beta 4 is a protein that is made up of 43 amino acids. The TMSB4X gene found in the test subject's body encodes the peptide. There have been a variety of clinical trials that have been performed using this peptide. In the research, it’s been found that the Thymosin Beta 4 may be used after a heart attack takes place in order to reactivate the cells in the cardiac progenitor, so that repair can be done to the damaged tissue in the heart.
Oxytocin is relatively safe when used at recommended doses. Potential side effects include: Central nervous system: Subarachnoid hemorrhage, seizures; Cardiovascular: Increased heart rate, blood pressure, systemic venous return, cardiac output, and arrhythmias;Genitourinary: Impaired uterine blood flow, pelvic hematoma, tetanic uterine contractions, uterine rupture, postpartum hemorrhage.
A: 5-HTP or 5-hydroxytryptophan is sold as a dietary supplement for "anxiety, depression, insomnia, headaches and other conditions." Because dietary supplements (e.g., 5-HTP) have not been thoroughly studied in the clinical setting, possible side effects and interactions with other drugs are not well known. However, 5-HTP does interact with prescription antidepressants, taking them together can lead to serotonin syndrome which is a rare but potentially fatal condition. Also, because herbs and supplements are not strictly regulated by the U.S. Food and Drug Administration, these products are not required to be tested for effectiveness, purity, or safety. 5-HTP has not been proven safe or effective for the treatment of depression or bipolar disorder. There are many prescription medications that have been proven safe and effective for these conditions. In general, dietary supplements should only be taken under the supervision of your health care provider. Laura Cable, Pharm.D., BCPS

5-HTP is POSSIBLY SAFE when taking by mouth appropriately. 5-HTP has been used safely in doses up to 400 mg daily for up to one year. However, some people who have taken it have developed a condition called eosinophilia-myalgia syndrome (EMS), a serious condition involving extreme muscle tenderness (myalgia) and blood abnormalities (eosinophilia). Some people think EMS might be caused by an accidental ingredient or contaminant in some 5-HTP products. However, there is not enough scientific evidence to know if EMS is caused by 5-HTP, a contaminant, or some other factor. Until more is known, 5-HTP should be used cautiously.
We have evaluated the efficacy of early Tβ4 treatment on spatial learning and sensorimotor functional recovery in rats after TBI induced by unilateral CCI.34 In brief, TBI rats received Tβ4 at a dose of either 6 or 30 mg/kg (RegeneRx Biopharmaceuticals Inc, Rockville, MD) or a vehicle control (saline) administered i.p. starting at 6 hours after injury and then at 24 and 48 hours. Spatial learning was performed during the last five days (31-35 days post injury) using the modified Morris water maze (MWM) test, which is extremely sensitive to the hippocampal injury.35-37 Tβ4-treated TBI rats showed significant improvement in spatial learning when compared to the saline-treated TBI rats. Tβ4 treatment also significantly reduced the swim latency to reach the hidden platform by rats post TBI compared to saline treatment. Using the modified Neurological Severity Score (mNSS) test, our data show that significantly improved scores were observed after TBI in the Tβ4-treated group compared to the saline-treated group. Our data also show that Tβ4 reduced the incidence of both right forelimb and hindlimb footfaults in TBI rats.34 Histological data show that early Tβ4 treatment reduced cortical lesion volume by 20% and 30% for 6 mg/kg and 30 mg/kg, respectively, and reduced hippocampal cell loss. These findings suggest that TB4 provides neuroprotection even when the treatment was initiated 6 hours post injury. In addition, 6-hour Tβ4 treatment promotes neurogenesis in the dentate gyrus (DG) of the hippocampus,38 which may contribute to improvement in spatial learning.
Astrocytes constitute the largest population of cells in the central nervous system, constituting approximately 90% of human parenchymal cells. Astrocytes are highly responsive to injury, undergoing rapid hyperplasia and hypertrophy. Astrocytes act as physical and biochemical barriers to axonal regeneration by forming glial scars along ischemic lesions and producing axonal growth-inhibitory proteoglycans. Administration of MSCs significantly attenuates the glial scar in the ischemic boundary and reduces expression of inhibitory proteins, such as Nogo. Analysis of single-cell astrocytes isolated from the ischemic boundary by laser capture microdissection reveals that administration of MSCs dramatically down regulates neurocan, an axonal growth-inhibitory proteoglycan. Coculture of MSCs with astrocytes also substantially reduces neurocan expression in astrocytes activated by oxygen glucose deprivation. These findings suggest that injected MSCs reduce physical and biochemical barriers of astrocytes, which also contribute to axonal and neurite outgrowth.
Myocardial infarction and heart failure are severe causes for death in humans. Extracellular nucleotides (ATP and ADP) released at the site of myocardial damage induce thrombosis, apoptosis and necrosis. ENTPD1 (ectonucleoside triphosphate diphosphohydrolase 1, CD39) rapidly hydrolyzes ATP and ADP to AMP. An in vivo myocardial ischemia/reperfusion injury test in transgenic mice expressing human CD39 resulted in a decrease of the infarct size. The same transgene including the human CD39 cDNA driven by the murine MHC class I gene H-2Kb promoter was used for the generation of transgenic pigs via SCNT. Expression of human CD39 was detected on circulating blood cells and in myocardial tissue of the transgenic animals. After in vivo induction of myocardial ischemia/reperfusion injury, a reduction of the myocardial injury analogous to the results in the transgenic mice was found (Wheeler et al., 2012).
Osteoclast differentiation was assessed by tartrate-resistant acid phosphatase (TRAP) staining and activity. After 5 days of culture, cells were stained for TRAP kit using a leukocyte acid phosphatase kit (Sigma Aldrich, St Louis, MO, USA). Cells with three or more nuclei were counted as multinucleated mature osteoclasts. To measure TRAP activity, cells were fixed with 10% formalin for 10 min and 95% ethanol for 1 min, and then 100 μl of citrate buffer (50 mM, pH 4.6) containing 10 mM sodium tartrate and 5 mM p-nitrophenylphosphate (Sigma-Aldrich) was added to the wells containing fixed cells in the 48-well plates. After incubation for 1 h, enzyme reaction mixtures in the wells were transferred to new plates containing an equal volume of 0.1 N NaOH. Absorbance was measured at 410 nm using a microplate reader.

Some differences in cardiac anatomy exist between mammals and teleosts. The zebrafish ventricle has a thin wall of compact muscle surrounding a much larger compartment of myofibers organized into elaborate trabeculae. It is intriguing that this structure is very similar to that of the embryonic mammalian ventricle prior to its septation and fusion of trabeculer myofibers into a thick, vascularized wall (Sedmera et al., 2000). That the mammalian heart has a more differentiated, contractile anatomy is apparent not only in gross cardiac structure, but also in cellular features. Teleost cardiomyocytes are 2–10 times smaller, mononucleated, have a greatly-reduced sarcoplasmic reticulum and lack the T-tubule system found in skeletal muscle and mammalian cardiac muscle (Farrell, 1992). One might speculate that the teleost heart is better designed for growth and regeneration, while the mammalian heart is better designed for sheer contractile force. Nevertheless, none of the mentioned differences between lower and higher vertebrate hearts preclude the idea that the mammalian heart could be stimulated to regenerate, especially if that regeneration is due to mobilization of a progenitor cell population.

Maternal behavior: Female rats given oxytocin antagonists after giving birth do not exhibit typical maternal behavior.[59] By contrast, virgin female sheep show maternal behavior toward foreign lambs upon cerebrospinal fluid infusion of oxytocin, which they would not do otherwise.[60] Oxytocin is involved in the initiation of maternal behavior, not its maintenance; for example, it is higher in mothers after they interact with unfamiliar children rather than their own.[61]


I have taken BPC-157 in conjunction with TB-500 after reading about someone’s experience. I used the BPC-157 at an injury/inflammation site in my shoulder. I have a pain that came out of nowhere and has prevented me from doing bench presses mainly, and shoulder presses. I also got pain when I did external rotation of my shoulder. The BPC-157 gave me good results at 250 mcg twice daily intramuscularly. The pain is not completely gone but it has definitely lessened in severity. I don’t get any pain with a reverse grip press so I have been doing those with light weight and I can now do shoulder presses. BPC-157 really blew me away on how quickly it improved my gut status. For me it only took 4 days of orally dosing with 250 mcg. So I did both the oral and intramuscular daily for a month. Two weeks into the BPC-157 I ordered TB-500 and did 1mg per week subq in my thigh because I didn’t know about injecting intramuscularly at the injury site.
It has been shown that oxytocin differentially affects males and females. Females who are administered oxytocin are overall faster in responding to socially relevant stimuli than males who received oxytocin.[75][86] Additionally, after the administration of oxytocin, females show increased amygdala activity in response to threatening scenes; however, males do not show increased amygdala activation. This phenomenon can be explained by looking at the role of gonadal hormones, specifically estrogen, which modulate the enhanced threat processing seen in females. Estrogen has been shown to stimulate the release of oxytocin from the hypothalamus and promote receptor binding in the amygdala.[86]

Low oxytocin levels have been linked to autism and autistic spectrum disorders (e.g. Asperger syndrome) – a key element of these disorders being poor social functioning. Some scientists believe oxytocin could be used to treat these disorders. In addition, low oxytocin has been linked to depressive symptoms and it has been proposed as a treatment for depressive disorders. However, there is not enough evidence at present to support its use for any of these conditions.
Thymosin Beta 4 is a potent peptide that comes from a family of 16 related molecules that are localized in circulating cells and tissues within the body. These molecules also have a high conservation of sequence. TB 500 conjoins with actin and prevents actin polymerization. It is noted as being the actin-sequestering molecule within eukaryotic cells. It also boosts extracellular matrix-degrading enzyme production.
Monomeric β-thymosins, i.e. those of molecular weight similar to the peptides originally isolated from thymus by Goldstein, are found almost exclusively in cells of multicellular animals.[4] Known exceptions are monomeric thymosins found in a few single-celled organisms, significantly those currently regarded as the closest relatives of multicellular animals:[5] choanoflagellates [6] and filastereans.[7] Although found in very early-diverged animals such as sponges, monomeric thymosins are absent from arthropods and nematodes, which do nevertheless possess "β-thymosin repeat proteins" which are constructed from several end-to-end repeats of β-thymosin sequences.[8] Genomics has shown that tetrapods (land vertebrates) each express three monomeric β-thymosins, which are the animal species' equivalents (orthologues) of human β4, β10 and β15 thymosins, respectively. The human thymosins are encoded by the genes TMSB4X, TMSB10 and TMSB15A and TMSB15B. (In humans, the proteins encoded by the two TMSB15 genes are identical.) Bony fish in general express orthologues of these same three, plus an additional copy of the β4 orthologue.[9]
Bone loss associated with inflammatory diseases, such as rheumatoid arthritis, periodontal disease, and osteoporosis, and elevated osteoclast activity leads to bone destruction [1]. The most common osteolytic disease, periodontitis, is a multi-factorial irreversible and cumulative condition, initiated and propagated by bacteria and host factors [2]. Destruction of peridontal tissue is mediated via the expression of various tissue-destructive enzymes or inflammatory mediators such as interleukins-1 (IL-1), IL-6 and IL-8, tumor necrosis factor- α (TNF- α), nitric oxide (NO), and prostaglandin E2 (PGE2) [2]. Receptor activator of nuclear factor-kappa B (NF-κB) ligand (RANKL) and osteoprotegerin (OPG) are critical for homeostatic control of osteoclast activity, suggesting that they have vital roles in the progression of bone loss in periodontitis [3, 4]. Therefore, resolution of inflammation and blocking osteoclast differentiation might be a potential therapeutic approach for the prevention and treatment of osteolytic inflammatory disease, such as periodontitis [5].
Mouse bone marrow macrophage (BMMs) of 5-week-old female ICR mice (Charles River Laboratories, Seoul, South Korea) were used as previously described [23]. Animals were maintained in accordance with the National Institute of Toxicological Research of the Korea Food and Drug Administration guideline for the humane care and use of laboratory animals Institutional Animal Care and Use Committee (IACUC) approval was obtained from Kyung Hee University (Seoul, Korea). Briefly, bone marrow of tibiae and femurs of mice were flushed with α-MEM. After removing erythrocytes with hypotonic buffer, cells were cultured in α-MEM containing 10% FBS for 24 h and adherent cells were discarded. Non-adherent bone marrow cells were transferred onto 100-mm non-coated petri dishes at 5×106 cells per dish and cultured in the presence of M-CSF (30 ng/ml) for 3 days. Condition medium (CM) was obtained from HPDLCs treated with 200 μM H2O2 or Tβ4 (0.5, 1 and 5 μg/mL) for 2 days. To evaluate the osteoclastogenic activity of CM from HPDLCs, we added the CM mixture (60% CM plus 40% fresh α-MEM without M-CSF or RANKL) or rh-Tβ4 to pre-osteoclast-stage cells and further cultured the cells for up to 5 days to achieve mature osteoclast differentiation BMMs (1.5 × 105 cells/well) and PDLCs (1.5 × 104 cells/well) were co-cultured for 7 days in the presence of M-CSF (30 ng/ml), RANKL (100 ng/mL), H2O2 (200 μM) or Tβ4 (0.5, 1 and 5 μg/mL) in α-MEM, supplemented with10% in 48-well plates under 5% CO2 atmosphere.
The polyherbal formula described for acute wounds promoted both angiogenesis and fibroblast proliferation and collagen synthesis in a streptozotocin diabetic rat model (Gupta et al., 2008). Dressings impregnated with copper oxide applied to wounds of diabetic mice resulted in the upregulation of the pro-angiogenic factors placental growth factor, hypoxia-inducible factor-1α and VEGF, leading to increased angiogenesis and faster wound closure (Borkow et al., 2010). High-throughput screening of medicinal plants known to be beneficial for blood circulation identified a material named SBD.4a from the plant Angelica sinensis as having angiogenic properties on a par with PDGF-BB (Zhao et al., 2006).

Because of its role in creating serotonin, 5-HTP is indirectly involved in producing melatonin, a hormone that is critical for sleep. Melatonin helps the body’s bio clock stay in sync, and regulates daily sleep-wake cycles. A strong bio clock and regular sleep-wake routines are the cornerstone of healthy, restful, rejuvenating sleep. Research suggests that 5-HTP may help shorten the time it takes to fall asleep and increase sleep amounts.

Animal studies have found high levels of both stress and oxytocin in voles that were separated from other voles. However, when the voles were given doses of oxytocin, their levels of anxiety, cardiac stress, and depression fell, suggesting that stress increases internal production of the hormone, while externally supplied doses can help reduce stress.
According to recent research, this hormone “is now believed to be involved in a wide variety of physiological and pathological functions such as sexual activity, penile erection, ejaculation, pregnancy, uterine contraction, milk ejection, maternal behavior, social bonding, stress and probably many more, which makes oxytocin and its receptor potential candidates as targets for drug therapy. From an innocuous agent as an aid in labor and delivery, oxytocin has come a long way in being touted as the latest party drug.”4
Autism: Oxytocin has been implicated in the etiology of autism, with one report suggesting autism is correlated with genomic deletion of the gene containing the oxytocin receptor gene (OXTR). Studies involving Caucasian and Finnish samples and Chinese Han families provide support for the relationship of OXTR with autism.[55][56] Autism may also be associated with an aberrant methylation of OXTR.[55]
The pamphlet, titled "Melanotan-2: Safe enhanced tanning" says although the drug is not approved by the Therapeutic Goods Administration (Australia's drug watchdog) and that studies into its effects are under way, it "is safe" and and its use "well documented". It says people can be referred to a "suitable doctor who is trained to prescribe MT2" so the pharmacy can dispense it to them.

In 19 obese females given either placebo or 8mg/kg (weight not actually given, only BMI between 30-40 for women) daily for 5 weeks without any concurrent dietary recommendations, 5-HTP treatment was associated with a decrease in appetite and food intake (resulting in weight loss) without significantly affecting mood state.[9] This study noted that food intake was reduced from an average of 2,903kcal to 1,819kcal (62% of baseline) while placebo only reduced calories to 80%, and the 0.5kg weight loss in placebo was outperformed by a near 1.5kg loss in 5-HTP. These weight loss effects have been noted with 750mg 5-HTP over 2 weeks in overweight diabetics[10] and over 12 weeks in obese persons given 900mg 5-HTP daily (58% of baseline intake); this latter study had a 6 week trial without a diet (in which significant weight loss was only noted at week 6) followed up by coadministration with a diet where weight loss proceeded to reach an additional 3.3kg over the subsequent 6 weeks;[11] this latter study is duplicated in Medline.[12]
A later experiment by another group took it a step further. This time the volunteers were told how they did, and in half of the cases, they learned that the trustee had burned them and kept the money. The volunteers who were burned were asked whether they wanted to try again. What would you do? This would be like getting that spam from the Nigerian Prince a second time and sending him $5,000 again, right?

There is also a positive feedback involved in the milk-ejection reflex. When a baby sucks at the breast of its mother, the stimulation leads to oxytocin secretion into the blood, which then causes milk to be let down into the breast. Oxytocin is also released into the brain to help stimulate further oxytocin secretion. These processes are self-limiting; production of the hormone is stopped after the baby is delivered or when the baby stops feeding.


How would that work? Feldman thinks that these types of behaviors are intimately linked with oxytocin in a positive feedback loop. “Oxytocin can elicit loving behaviors, but giving and receiving these behaviors also promotes the release of oxytocin and leads to more of these behaviors,” she says. She thinks that talk therapy alone can boost the oxytocin system, but admits that in some cases it might help to jump-start the feedback loop by administering oxytocin. If Guastella’s results support his hypothesis, talk and hormone therapy together might be the best recipe for breaking down dysfunctional communication between partners, especially in cases where the behaviors have been learned in childhood.
A and B; Mouse BMMs were cultured with 200 μM H2O2 and indicated concentrations of Tβ4 peptide in the presence of M-CSF (30 ng/mL) and RANKL (100 ng/mL). C and D; PDLCs were co-cultured with mouse BMMs in the presence of M-CSF, RANKL, 200 μM H2O2, and indicated concentrations of Tβ4 peptide. To monitor osteoclast differentiation, both TRAP activity and the number of TRAP multinucleated cells were examined. * Statistically significant difference compared with control, p<0.05. The data presented were representative of three independent experiments.
The full-length Tβ4 polypeptide has been shown to be effective in reducing inflammation [44]. It is also reported that only the 4-AA, amino-terminal peptide of Tβ4, known as Ac-SDKP, can block inflammation [45]. In this study, we used a synthetically human peptide produced copy of a naturally occurring, highly conserved 43-amino acid (MW = 4964 Da) water soluble acidic peptide, originally isolated from bovine thymus tissue [46]. This peptide is produced by Fmoc solid-phase peptide synthesis in accordance with the current Good Manufacturing Practice (cGMP) regulations (21 CFR 210 and 211) of the FDA [47]. An effective healer, Tβ4 can be administered topically on the surface of cells and systemically, through injection [9–11]. In this study, Tβ4 activation by Tβ4 peptide inhibited H2O2-induced production of NO and PGE2, expression of COX-2 and iNOS, and mRNA expression of TNF- α, IL-1β, -6, -8, and -17 in cultured PDLCs. These findings suggested that Tβ4 activation possessed anti-inflammatory activity in PDLCs. These results were consistent with previous in vivo and in vitro studies [9–15]. MAPK is a proline-directed serine/threonine kinase consisting of three-enzyme modules; its targets, inducing ERK, JNK and p38 kinases, are important in cellular signal transduction pathways and exert an anti-inflammatory response [48, 49]. NF-κB is a major transcription factor involved in the release of proteins that mediate the inflammatory response, and the degradation and phosphorylation of Iκ-Bα are necessary to release NF-κB from the cytoplasmic NF-κB/Iκ-Bα complex and allow its subsequent translocation to the nucleus of the cell [50]. In this study, Tβ4 peptide down-regulated the H2O2-triggered activation of the ERK and JNK MAPKs and the NF-κB in PDLCs. These results suggested that the ERK and JNK MAPKs and the NF-κB pathway may be involved in the anti-inflammatory effects of Tβ4 activation in PDLCs. Consistent with our findings, Tβ4 treatment decreased TNF-α-induced NF-κB activation in human corneal epithelial cells [51].
Nasally administered oxytocin has been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses).[76] Indeed, studies in rodents have shown oxytocin can efficiently inhibit fear responses by activating an inhibitory circuit within the amygdala.[77][78] Some researchers have argued oxytocin has a general enhancing effect on all social emotions, since intranasal administration of oxytocin also increases envy and Schadenfreude.[79] Individuals who receive an intranasal dose of oxytocin identify facial expressions of disgust more quickly than individuals who do not receive oxytocin.[75][qualify evidence] Facial expressions of disgust are evolutionarily linked to the idea of contagion. Thus, oxytocin increases the salience of cues that imply contamination, which leads to a faster response because these cues are especially relevant for survival. In another study, after administration of oxytocin, individuals displayed an enhanced ability to recognize expressions of fear compared to the individuals who received the placebo.[80] Oxytocin modulates fear responses by enhancing the maintenance of social memories. Rats that are genetically modified to have a surplus of oxytocin receptors display a greater fear response to a previously conditioned stressor. Oxytocin enhances the aversive social memory, leading the rat to display a greater fear response when the aversive stimulus is encountered again.[74]
Maintenance doses are taken once the desired pigmentation has been reached and requires much less frequent dosing. Unfortunately, this is where too many variables come into play to give exact instructions. Skin type, bodyweight, metabolism regulating speed of skin fading, uv ray exposure, preferred tan level – all that makes impossible to give correct advice on maintenance dose. Everyone will find their own perfect dose and dosing frequency through some trial and error. To not leave you completely disinformed on this subject here is example of loading and maintenance which can be used as starting point where to adjust from:
Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours, post-incubated with 200 μM H2O2 for 48 hours, and then conditioned medium (CM) was collected. Mouse BMMs were cultured with CM in the presence of M-CSF (30 ng/mL) and RANKL (100 ng/mL), as described in Materials and methods. After 5 days, cells were fixed and stained for TRAP as a marker of osteoclasts (A), and the number of TRAP-positive multinucleated cells (MNCs) was scored (B). TRAP osteoclast activity was assayed using the TRAP cytochemical stain technique (C). * Statistically significant differences compared with the control, p<0.05. The data presented were representative of three independent experiments.
Recent preclinical studies by us and others have revealed that endogenous neurorestoration is present after TBI, including neurogenesis, axonal sprouting, synaptogenesis, and angiogenesis, which may contribute to the spontaneous functional recovery.13-18 In addition, treatments that promote these neurorestorative processes have been demonstrated to improve functional recovery after brain injury.19,20 However, clinical trials in TBI have primarily targeted neuroprotection, and trials directed specifically at neurorestoration have not been conducted. The essential difference between neuroprotective and neurorestorative treatments is that the former target the lesion that is still not irreversibly injured and the latter treat the intact tissue.19 Thus, neurorestorative treatments can be made available for a larger number of TBI patients.
Though it may be unlikely to form part of any official psychiatric programme in the UK, Phil Cowen, Professor of Psychopharmacology at Oxford University, admitted that there are various groups for whom it could be helpful. "About half of people with severe depression never see a doctor anyway, so it's reasonable to think it's fine for them to treat themselves with something like a supplement. Perhaps if you had mild symptoms, a smaller dose would be helpful. I'd also prefer to prescribe things like exercise or computer-based CBT if it's that stage, though. But depression and anxiety is very different between people, that's important to keep in mind. No treatment is the same for anyone."
Oxytocin is a hormone that also acts as a neurotransmitter in the brain. Some popular media have incorrectly labeled it the “love hormone,” because it is associated with good feelings and emotions. But its role in the body is much more complex than that. It is not a bliss or hug hormone, but it does appear to be connected to human emotions and the regulation of childbirth and breast-feeding.
Oxytocin and vasopressin are the only known hormones released by the human posterior pituitary gland to act at a distance. However, oxytocin neurons make other peptides, including corticotropin-releasing hormone and dynorphin, for example, that act locally. The magnocellular neurosecretory cells that make oxytocin are adjacent to magnocellular neurosecretory cells that make vasopressin. These are large neuroendocrine neurons which are excitable and can generate action potentials.[124]
5-HTP is POSSIBLY SAFE when taking by mouth appropriately. 5-HTP has been used safely in doses up to 400 mg daily for up to one year. However, some people who have taken it have developed a condition called eosinophilia-myalgia syndrome (EMS), a serious condition involving extreme muscle tenderness (myalgia) and blood abnormalities (eosinophilia). Some people think EMS might be caused by an accidental ingredient or contaminant in some 5-HTP products. However, there is not enough scientific evidence to know if EMS is caused by 5-HTP, a contaminant, or some other factor. Until more is known, 5-HTP should be used cautiously.
