The scientists discovered that oxytocin strengthens negative social memory and future anxiety by triggering an important signaling molecule -- ERK (extracellular signal regulated kinases) -- that becomes activated for six hours after a negative social experience. ERK causes enhanced fear, Radulovic believes, by stimulating the brain's fear pathways, many of which pass through the lateral septum. The region is involved in emotional and stress responses.
Cognitive impairment has repeatedly been described in bipolar disorders… Serotonin (5-hydroxytryptophan; 5-HT) is possibly involved in these cognitive processes, more particularly in executive functions, learning, memory, and attention. The aim of this study was to investigate serotonergic vulnerability and its relation to cognitive functioning in healthy first-degree relatives of [bipolar disorders] patients…
Do I have to diet? Studies show that 5-HTP enhances weight loss even if you continue eating your normal foods. Without a diet, you stand to lose about a pound a week; many folks eventually drop 15 pounds or more without dieting. Of course, taking 5-HTP to lose weight works by lowering caloric intake — and the more calories you cut, the more you’ll lose. So if you want to maximize results, try tweaking your diet at the two-week mark, when 5-HTP will have fully kicked in, diminishing hunger and carb cravings. Below, we’ve got a version of the diet used in one university study that helped 5-HTP takers lose several times more weight than folks getting a placebo.

There have been encouraging results for the use of Tβ4 as a topical gel to treat venous stasis ulcers, a type of wound that develops on the lower leg of patients with chronic vascular disease. Two other reports indicated that Tβ4, formulated in eye-drops, may enhance corneal wound healing in diabetic patients, and improve ocular discomfort. These are the most advanced trials to date. As of yet, despite promising animal models, there has been no significant study exploring the efficacy of intravenous Tβ4 injections in treating ischemic heart injury.
Oxytocin has been shown to help people with autism improve their ability to recognize emotion, and Wallum found that the same receptor variant that increases risk for marital crisis in women is linked to social problems in girls. These include trouble getting along with others and a preference for being alone. This and Feldman’s work on oxytocin’s importance for the mother–child bond suggests that the hormone is more involved in the communication component of love between couples than the romantic component of love.
Tβ4 was down-regulated in H2O2-exposed PDLCs in dose- and time-dependent manners. Tβ4 activation with a Tβ4 peptide attenuated the H2O2-induced production of NO and PGE2 and up-regulated iNOS, COX-2, and osteoclastogenic cytokines (TNF-α, IL-1β, IL-6, IL-8, and IL-17) as well as reversed the effect on RANKL and OPG in PDLCs. Tβ4 peptide inhibited the effects of H2O2 on the activation of ERK and JNK MAPK, and NF-κB in PDLCs. Furthermore, Tβ4 peptide inhibited osteoclast differentiation, osteoclast-specific gene expression, and p38, ERK, and JNK phosphorylation and NF-κB activation in RANKL-stimulated BMMs. In addition, H2O2 up-regulated Wnt5a and its cell surface receptors, Frizzled and Ror2 in PDLCs. Wnt5a inhibition by Wnt5a siRNA enhanced the effects of Tβ4 on H2O2-mediated induction of pro-inflammatory cytokines and osteoclastogenic cytokines as well as helping osteoclastic differentiation whereas Wnt5a activation by Wnt5a peptide reversed it.
I am not sure if my original question posted…I was wondering if I could use TB-500 to regenerate thyroid tissue? My endocrinologist said that my Hashimoto’s Thyroiditis has almost completely destroyed my thyroid. If yes, then where do I inject?? Additionally, I was wonder if the BPC-157 would have any benefits on thyroid as I plan to take orally for leaky gut/digestive issues.
At least one study using an extract of Griffonia simplicifolia (10.24mg giving 2.56mg 5-HTP; confounded with Centella asiatica and Taraxacum officinale at 11.7mg and 4.55mg Paulina cupana and 9.75mg Artichoke extract) taken in three hits, five times a day (40mg 5-HTP total), by 20 overweight or obese females (non-depressive and without eating disorders) for 4 weeks has noted an increase in satiety and reduced binge eating tendencies; the increase in satiety was said to account for the improved weight loss results seen in the experimental group when both were given weight loss advice and diets.[3] This spray has been noted elsewhere to increase satiety (and vicariously through that, body weight) over 2 months in a similar demographic of women.[2]
In women, oxytocin is responsible for signaling contractions of the womb during labor. The hormone stimulates the uterine muscles to contract, so labor begins. It also increases the production of prostaglandins, which move labor along and increases the contractions even more. Because of this effect, synthetic oxytocin (pitocin) is sometimes used to induce a woman to start labor if she cannot start naturally, or it can be given to make contractions stronger if a woman's labor is slowing.

In humans, 5-HTP is the nutrient precursor to the neurotransmitter serotonin – widely known as the 'happy neurotransmitter' – meaning 5-HTP converts directly into serotonin in the brain. As well as being in our bodies, it's found naturally in the seeds of a woody shrub native to West Africa. By taking it as a supplement, in theory, you will end up with more serotonin in your brain. Serotonin deficiency is linked to depression, anxiety and a whole host of physical and mental ailments. Raising its levels seems to help brain cells send and receive chemical messages, which in turn boosts mood.
Melanotan peptides are stable and durable when shipped, surviving about 37 degrees temperatures for around a month or more. Even during summer, this peptide can be shipped without hassles. Once they have been received, they ought to be put away in the refrigerator or better still, freezer to avert conceivable deterioration until ready to be mixed, which then the mixed Melanotan is stored in the refrigerator.

My physiotherapist suggested BCP-157. We injected this into the palm for a few weeks 3x week. We then worked up a 50/50 mix of BCP and TB500. I’ve upped my injections ( 5-7 injections) into the surrounding areas of the protruding nodes in my palm. The results have been significant. Into week 6 of a 3x injection program, and the chords are opening up (reacting to the ‘rematrixing’ of the cells). The TB seems to disperse the liquid throughout my palm. My ‘clutched palm’ is reduced and flexibility is restored. We’re going to stick with this for another couple of months.
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 (Oxt; /ˌɒksɪˈtoʊsɪn/) is a peptide hormone and neuropeptide. Oxytocin is normally produced by the paraventricular nucleus of the hypothalamus and released by the posterior pituitary.[3] It plays a role in social bonding, sexual reproduction, and during and after childbirth.[4] Oxytocin is released into the bloodstream as a hormone in response to stretching of the cervix and uterus during labor and with stimulation of the nipples from breastfeeding.[5] This helps with birth, bonding with the baby, and milk production.[5][6] Oxytocin was discovered by Henry Dale in 1906.[7] Its molecular structure was determined in 1952.[8] Oxytocin is also used as a medication to facilitate childbirth.[9][10][11]
Addiction vulnerability: Concentrations of endogenous oxytocin can impact the effects of various drugs and one's susceptibility to substance use disorders. Additionally, bilateral interactions with numerous systems, including the dopamine system, Hypothalamic–pituitary–adrenal axis and immune system, can impact development of dependence. The status of the endogenous oxytocin system might enhance or reduce susceptibility to addiction through its interaction with these systems. Individual differences in the endogenous oxytocin system based on genetic predisposition, gender and environmental influences, may therefore affect addiction vulnerability.[72] Oxytocin may be related to the place conditioning behaviors observed in habitual drug abusers.

Synthetic oxytocin is sold as medication under the trade names Pitocin and Syntocinon and also as generic oxytocin. Oxytocin is destroyed in the gastrointestinal tract, and therefore must be administered by injection or as nasal spray. Oxytocin has a half-life of typically about three minutes in the blood. Oxytocin given intravenously does not enter the brain in significant quantities - it is excluded from the brain by the blood-brain barrier. There is no evidence for significant CNS entry of oxytocin by nasal spray. Oxytocin nasal sprays have been used to stimulate breastfeeding but the efficacy of this approach is doubtful[24].
Noteworthy:  Many online sources sell an ineffective product.  Also, peptides are fragile by nature and are not effective when they are taken orally (pills, shakes, etc) because they will be broken down by the digestive process. Instead, peptides are mixed with bacteriostatic water and then injected under the skin with an insulin needle. Peptide injections in this manner are nearly painless and have clinically proven effectiveness.
RegeneRX Biopharmaceuticals is focusing on the commercialization of Tb4 “For the treatment of injured tissue and non-healing wounds, to enable more rapid repair and/or tissue regeneration.” Especially needy are diabetics who suffer from poor blood circulation and loss of sensation of pain that keeps their wounds unnoticed and unattended for days, leading to ulcers that may not heal. Other hard healing wounds are pressure ulcers in patients who are bed ridden and often receive skin grafts as treatment, or reconstructive surgery.
5-HTP can affect a brain chemical called serotonin. Dextromethorphan (Robitussin DM, others) can also affect serotonin. Taking 5-HTP along with dextromethorphan (Robitussin DM, others) might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Do not take 5-HTP if you are taking dextromethorphan (Robitussin DM, and others).

The idea that oxytocin is central to social cognition made it an attractive candidate for treating psychiatric disorders, especially autism spectrum disorder. People with this condition, who often have problems with social interaction and communication, may not process social stimuli appropriately — and scientists theorized that oxytocin might reverse some of the symptoms. Beginning in 2010, results emerged that seemed to support this theory: researchers found that single puffs of oxytocin could temporarily improve measures of empathy and social cooperation in people with autism spectrum disorder.

Thymosin beta-4 (Tβ4) is a water-soluble, 43-amino acid, and 4.9 kDa protein that was originally isolated from bovine thymus [6]. Since Tβ4 is the major actin-sequestering molecule in eukaryotic cells and is found in all cells [7], Tβ4 has multiple diverse cellular functions, including tissue development, migration, angiogenesis, and wound healing [7]. We previously reported that Tβ4-overexpressing transgenic mice, using a construct on the skin-specific keratin-5 promoter, have abnormal tooth development and enhanced stimulation of hair growth [8]. Moreover, exogenous Tβ4 has anti-inflammatory effects in the bleomycin-induced mouse model of lung fibrosis [9], tooth extraction sockets in rats [10], rat model of myocardial ischemia [11], corneal wound healing [12], wound healing of rat palatal mucosa [13], in vitro model of cultured human gingival fibroblasts [14], and cardiac fibroblasts [15]. However, the effects of Tβ4 over expression or inhibition on differentiation are controversial. Exogenous β4 peptide inhibited osteogenic differentiation but facilitated adipogenic differentiation in human bone marrow-derived-mesenchymal stem cells (MSCs) [16]. In contrast, Tβ4 inhibition by Tβ4 siRNA attenuated odontoblastic differentiation in the odontoblast-like cells, MDPC-23 [17]. Moreover, we recently demonstrated that odontoblastic differentiation was enhanced by activation of Tβ4 by Tβ4 peptide but was decreased by Tβ4 siRNA in human dental pulp cells (HDPCs) [18]. However, the effects of Tβ4 on osteoclastic differentiation have not been reported.

The neurotransmitter serotonin is synthesized from the amino acid tryptophan through 5-HTP. In which tryptophan gets converted into 5-HTP via the enzyme tryptophan hydroxylase and 5-HTP gets converted into serotonin via the enzyme L-amino acid decarboxylase.[4] Serotonin is later degraded into 5-hydroxyindoleacetic acid (5-HIAA) by monoamine oxidase.

Tβ4 is the major monomeric actin-sequestering peptide in human tissues, and can bind globular actin (G-actin) in a 1:1 ratio and consequently involved in cytoskeletal regulation by inhibiting the polymerization of G-actin into fibrous actin (F-actin) [7]. In addition, Tβ4 is an ubiquitous naturally occurring molecule and is found at concentrations of 1 × 10−5 to 5.6 × 10−1 M in a variety of tissues and cell types, yet, no receptors for the protein have been identified [33]. A recent study suggests that internalization of exogenous Tβ4 is essential for its subsequent cellular functions [34]. Moreover, Tβ4 has been shown to be associated with, wound healing, hair growth, immunomodulation, and angiogenesis [7–9].
In regards to interventions, one study in treatment resistant depressed persons that combination therapy of 5-HTP with Carbidopa noted that 43 out of 99 (43.4%) patients improved with an average 200mg (variable 50-600mg) dosage of 5-HTP.[24] It has been noted[25] that since Cardidopa is a peripheral decarboxylase inhibitor that can prevent metabolism of monoamines including serotonin[26] that these results are unlikely to reflect monotherapy with 5-HTP, despite being within the 30-45% range sometimes seen with the placebo effect.[25][27]
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.
Cells were incubated with 200 μM H2O2 for indicated times (A). Cells were pretreated with indicated concentrations of Tβ4 peptide (0.1–5 μg/mL) for 2 hours and then incubated with 200 μM H2O2 for 60 minutes (B). Data were representative of three independent experiments. The bar graph shows the fold increase in protein expression compared with control cells * Statistically significant differences compared with the control, p<0.05. # Statistically significant difference compared with the H2O2—treated group.

To determine the effects of Tβ4 peptide and H2O2 on cytotoxicity, its cell viability was evaluated. A 48-h exposure to 0.1–5 μg/mL Tβ4 peptide did not affect H2O2-mediated cell viabilities (Fig 2A). In order to examine whether Tβ4 peptide suppressed ROS-induced inflammatory mediators, the ability of Tβ4 peptide on production of NO and PGE2, and expressions of COX-2 and iNOS were measured by RT-PCR, Western blot, and ELISA. Pretreatment with Tβ4 peptide dose-dependently inhibited H2O2-induced mRNA and protein expressions of COX-2 and iNOS, and NO and PGE2 production (Fig 2B–2E).
Potential side effects of 5-HTP include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, vivid dreams or nightmares, and muscle problems.[19] Because 5-HTP has not been thoroughly studied in a clinical setting, possible side effects and interactions with other drugs are not well known. According to the US National Institute of Health TOXNET, 5-HTP has not been associated with serotonin syndrome or any serious adverse events in humans.[20] Across multiple studies, 5-HTP also been reported to not cause any noticeable hematological or cardiovascular changes.[21] 5-HTP also has not been associated with eosinophilia.[22]
