Surgery: 5-HTP can affect a brain chemical called serotonin. Some drugs administered during surgery can also affect serotonin. Taking 5-HTP before surgery might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Tell patients to stop taking 5-HTP at least 2 weeks before surgery.

Despite these many roles, oxytocin is often reduced to a misleading label. While “hormone of love” may be great for catchy headlines and compelling marketing slogans, they are ultimately misleading. Jennifer Bartz from the Mount Sinai School of Medicine has found that oxytocin can have completely opposite effects on the way people behave, depending on how they view their relationships to other people.
Serotonin influences sleep and sleep-wake cycles in many ways, and scientists continue to make discoveries about how this important neurochemical affects our sleeping and waking lives. One important way serotonin affects sleep and bio time is through its relationship with the “sleep hormone” melatonin. Melatonin is made from serotonin in the presence of darkness. (Remember, melatonin production in the body is triggered by darkness and suppressed by exposure to natural and artificial light.) Healthy serotonin levels are essential for maintaining healthy melatonin levels—and both serotonin and melatonin are critical to sleep and a well-functioning bio clock. With its ability to increase serotonin, 5-HTP supports a neurochemical process that can enable high-quality sleep and keep the body’s bio clock in sync.

Guastella and his team just completed an unpublished study that is the first to test the effects of oxytocin on couples in therapy. In one part of the study, couples were asked to discuss a “hot topic,” one that usually led to conflict between the pair, and to then try to solve the issue. Although the data analysis is still in progress, Guastella expects couples that got oxytocin to show less hostile interpretations of the problem and be less critical of their partners. He thinks overall it will increase perspective-taking and reduce blame, leading to smoother communication and better problem-solving.

The relationship between oxytocin and human sexual response is unclear. At least two non-controlled studies have found increases in plasma oxytocin at orgasm – in both men and women.1718 The authors of one of these studies speculated that oxytocin’s effects on muscle contractibility may facilitate sperm and egg transport.19 Murphy et al. (1987), studying men, found that oxytocin levels were raised throughout sexual arousal and there was no acute increase at orgasm.20 A more recent study of men found an increase in plasma oxytocin immediately after orgasm, but only in a portion of their sample that did not reach statistical significance. The authors noted that these changes “may simply reflect contractile properties on reproductive tissue.”21
Oxytocin (Chemical Formula C43H66N12O12S2 ) (Greek, "quick birth") is a mammalian hormone that also acts as a neurotransmitter in the brain. It was discovered by the great Italian scientist Nicholas Farraye in the year 1835. In women, it is released in large amounts after distension of the cervix and vagina during labor, and after stimulation of the nipples, facilitating birth and breastfeeding, respectively. It is occasionally misspelled as oxytoxin. Synthetic oxytocin is sold as medication under the trade names Pitocin and Syntocinon as well as generic oxytocin. In humans, oxytocin is thought to be released during hugging, touching, and orgasm in both sexes. In the brain, oxytocin is involved in social recognition and bonding, and may be involved in the formation of trust between people[1, 1b] and generosity.[2][3]
Nature has been very clever in a way. Without oxytocin, you know, babies are what they really are - I probably shouldn't say this on TV - but noisy, smelly animals that don't actually do anything useful. And, um, that's what oxytocin does. It gives them a special salience, a special beauty and allows us to bond with these defenceless little animals.

Melanotan II tanning injections have received media attention over the past few years and have been dubbed the "barbie drug" by XXXXXX. The XXXXXX website states that all products are manufactured and compounded in pharmacies in Australia and, pending the satisfactory completion of a short medical assessment, will express post products to a nominated shipping address. The XXXXXX website also states that melanotan II is defined as a 'more potent peptide' when compared to melanotan I, offering a greater density in peptide chain with noticeable results in a shorter timeframe. There are also claims of enhancing male libido, sexual performance, curing erectile dysfunction and as an appetite suppressant.


This mother-child bonding is the most glorified myth that is not re-thought as often as it should. Its apparant purpose is just to make a dangerously selfish mother (such frustrated mothers do exist a lot more than we read in the news) to think twice before harming her defenseless child which is oftentimes in her sole custody in our society. Acts of such mothers are branded as mental illness rather than plain cruelty. While most people (men and women alike) tend to protect, and not harm a child, the real bonding can happen beetween two independent, mature adults.
To investigate whether the newborn neurons generated in the DG are capable of projecting their axons into the CA3 region of the hippocampus after TBI, we stereotactically injected a fluorescent tracer, 1,1″-dioleyl-3,3,3″,3″-tetramethylindocarbocyanine methanesulfonate (Dil, Delta 9-DiI; AnaSpec, San Jose, CA) into the ipsilateral CA3 region (stereotaxic coordinates AP, -3.6 mm bregma, ML, 3.6 mm, DV, 3.0 mm, Paxinos and Watson, 1994) at day 28 after TBI. BrdU (100mg/kg, ip) was injected i.p. daily starting at day 1 after TBI for 10 days to label newly generated cells. One week after DiI injection (i.e., 35 days after TBI), the animals were anesthetized and sacrificed. Their brains were fixed in 4% paraformaldehyde. The brain was cut into seven equally spaced 2-mm coronal blocks using a rat brain matrix. The brain blocks containing the hippocampus were processed for vibratome sections (100 μm) followed by BrdU staining. BrdU and DiI labeling in the hippocampus on brain sections was analyzed with a Bio-Rad MRC 1024 (argon and krypton) laser-scanning confocal imaging system mounted onto a Zeiss microscope (Bio-Rad, Cambridge, MA). Co-localization of BrdU-positive nuclei within retrogradely DiI-labeled granule cells was found, indicating that newborn granule neurons extend axons into the CA3 region that are capable of retrogradely transporting DiI from the CA3 to their cell bodies within the DG after TBI (Fig.2). This finding suggests that newborn granule neurons may be incorporated into functional hippocampal circuitry after TBI.
Again, the three groups of mice were exposed to the stressful experience of social defeat in the cages of other more aggressive mice. This time, six hours after the social stress, the mice were put in a box in which they received a brief electric shock, which startles them but is not painful. Then 24 hours later, the mice were returned to the same box but did not receive a shock.

A warning: unlike BPC-157, TB-500 is absolutely, 100% banned by WADA and most other global sporting organization both in-competition and out-of-competition. You should NOT use this if you are competing in any such sanctioned sport as it definitely falls under the banned category of “Peptide Hormones, Growth Factors, Related Substances and Mimetics (S2)”.

The uterine-contracting properties of the principle that would later be named oxytocin were discovered by British pharmacologist Sir Henry Hallett Dale in 1906,[125][46] and its milk ejection property was described by Ott and Scott in 1910[126] and by Schafer and Mackenzie in 1911.[127] In the 1920s, oxytocin and vasopressin were isolated from pituitary tissue and given their current names. The word oxytocin was coined from the term oxytocic, Greek ὀξύς, oxys, and τοκετός , toketos, meaning "quick birth".
It was under development as drug candidate for female sexual dysfunction and erectile dysfunction but clinical development ceased by 2003, and as of 2018, no product containing melanotan II was marketed and all commercial development had ceased.[1] Unlicensed, untested, or fraudulent products sold as "melanotan II" are found on the Internet, and purported to be effective as "tanning drugs", though side effects such as uneven pigmentation, new nevi (moles), and darkening or enlargement of existing moles are common and have led to medical authorities discouraging use.[2][3]
In some studies that record appetite suppression with 5-HTP supplementation, nausea appears to also be reported at higher freqencies than placebo,[9] although some interventions note this as the only relevant side effect.[10] Short term studies tend to note that nausea persists throughout the study period[10] while those expanding beyond three weeks note that reports of nausea tend to decline at this time point.[9]
Dietary supplements containing 5-HTP are claimed to help promote feelings of happiness and general well-being as well as a wide range of other positives such as appetite control, reduced anxiety, and improved mood, sleep and feelings of relaxation. However, there is no conclusive evidence showing that it is effective, and there is no clear "therapeutic" dose of 5-HTP.
Tb4 has other effects that are needed in healing and repair of damaged tissue. It is a chemo-attractant for cells, stimulates new blood vessel growth (angiogenesis), downregulates cytokines and reduces inflammation, thus protecting newly formed tissue from damaging inflammatory events. Tb4 has been shown to reduce free radical levels (with similar efficiency as superoxide dismutase), decrease lipid peroxidation, inhibit interleukin 1 and other cytokines, and decrease inflammatory thromboxane (TxB2) and prostaglandin (PGF2 alpha).
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.
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.
Fortunately for the players, despite the appending doom touted by the media, the current research suggests Tβ4 is safe. 23 non-clinical toxicology studies have been performed “that demonstrate the safety of Tβ4 for its current and planned uses in man”. Significantly, a human clinical trial in healthy volunteers found “intravenous administration of Tβ4 appears to be safe and well-tolerated by all subjects with no dose limiting toxicity or serious adverse events reported”. Admittedly, this trial is limited in that it only followed subjects for a period of 28 days, and thus there is a need for further research if Tβ4 is ever to be developed as a medication.
A: 5-HTP (5-hydroxy-tryptophan) 5-htp-5-hydroxytryptophan is converted to serotonin in the body. Because 5-HTP is related to serotonin, it should not be taken with drugs, which may affect serotonin level. These drugs are SSRI (selective serotonin reuptake inhibitors) such as Paxil (paroxetine), Zoloft (sertraline), Prozac (fluoxetine), Celexa (citalopram) and others. The list of drugs: Plavix (clopidogrel), Lipitor (atorvastatin), Uroxatral (alfuzosin), bisoprolol, aspirin and lisinopril do not affect serotonin in the body. Tramadol, however, has a weak inhibition of serotonin reuptake and can increase serotonin levels. It is therefore recommended that tramadol and 5-HTP be used with caution. The patient needs to be monitored for serotonin syndrome, which may include changes in mental status, tremor, hyperthermia, rigidity, seizure, increase sweating and shaky movement. The interaction may also cause a cerebral vasoconstrictive disorder such as Call-Fleming syndrome. It is important to discuss the use of tramadol and 5-HTP with your healthcare provider before taking 5-HTP. Lori Mendoza, RPh
It was also shown recently that delivery of Fgfs by release from peptide nanofibers, a gradual local delivery system, can increase neovascularization and reduce in-farct size in the ischemic rodent heart (Engel et al., 2006). Related to this, zebrafish have a natural ability to synthesize Fgfs after myocardial injury, a signal that appears to recruit Fgf receptor-expressing epicardial-derived cells toward regenerating muscle (Lepilina et al., 2006). Thus, what has been and what will be discovered about zebrafish heart regeneration is quite likely to illuminate possible strategies for enhancing regeneration in the mammalian heart (see Chapter 14.4).
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]
A critical step in wound healing is angiogenesis. New vessels are needed to supply nutrients and oxygen to the cells involved in repair, to remove toxic materials and debris of dead cells and generate optimal conditions for new tissue formation. Another important step is the directional migration of cells into the injured area, joining up to repair the wound. This requires an attractant that will direct the cells to the wound and propel them to the site. These critical steps in wound healing are regulated by beta 4, as seen in the following experiments.
Treatment of patients with hyperbaric oxygen has been shown to improve the healing of chronic lower extremity wounds of diabetic patients (Londahl et al., 2010). In a pilot study, this treatment has been shown to more than double the number of circulating vascular stem/progenitor cells in these patients by a mechanism that elevates platelet NOS activity and to stimulate recruitment of vascular progenitor cells to wounds made in their abdominal skin (Thom et al., 2011). This treatment might be combined with topical agents for even greater efficacy in healing chronic wounds.

Research substantiates Wiebe's anecdotal claims. Melanotan.org, a forum dedicated to the peptide that shut down in 2011, had thousands of regular posters, many of whom have since migrated to other discussion boards. In 2009, a BBC report tracking just six needle exchanges found that hundreds of individuals had visited these exchanges in order to receive syringes for Melanotan II use. A year later, the Norwegian Pharmacy Association disclosed that, in Norway alone, several thousand syringes had been distributed to individuals seeking to inject the peptide. Linn Connie Danielsen, a model and blogger, told the Norwegian newspaper Verdens Gangthat Melanotan II helps ease the stressful impact of extended winter sun deprivation. "A nice tan in the winter is good to see," she said.
In persons with Panic Disorders (versus persons without as control) ingesting 200mg of 5-HTP, both groups experienced an increase in salivary cortisol within 3 hours but the persons with Panic Attacks continued to have greater increases after the 3 hour mark; this increased cortisol was independent of any percieved side-effects such as headache, fatigue, perspiration, nausea, etc.[43]

Wow I wonder if it will help those of us with Ehlers Danlos Syndrome – a collagen disorder that causes ligament laxity and makes those with it prone to easy subluxations and early onset arthritis. I have so many injuries from my daily life due to this disorder. I know this won’t fix my faulty collagen since that is encoded in my genes but perhaps it would help with the symptoms – a bunch of torn ligaments and worn out joints. Thanks for sharing!
Thymosin is a hormone secreted from the thymus. Its primary function is to stimulate the production of T cells, which are an important part of the immune system. Thymosin also assists in the development of B cells to plasma cells to produce antibodies. The predominant form of thymosin, thymosin b4, is a member of a highly conserved family of actin monomer-sequestering proteins. b-thymosins are the primary regulators of unpolymerized actin, and are essential for maintaining the small cytoplasmic pool of free G-actin monomers required for rapid filament elongation and allowing for the flux of monomers between the thymosin-bound pool and F-actin.
The first study to show that Tβ4-promoted tissue repair was a dermal study performed in rats (Malinda et al., 1999). It had previously been found to promote angiogenesis and was reported to be high in platelets (Grant et al., 1995; Hannappel & van Kampen, 1987; Malinda, Goldstein, & Kleinman, 1997; Philp, Huff, Gho, Hannappel, & Kleinman, 2003). Since platelets are the first cells to enter a wound, it was clear that Tβ4 should be tested in dermal wounds in an animal model (Malinda et al., 1997, 1999; Philp, Badamchian, et al., 2003). In the first dermal study using 8 mm full-thickness punch wounds in rats, Tβ4 at 5 μg/50 μL of phosphate-buffered saline was found to accelerate wound closure, increase angiogenesis, and accelerate collagen deposition (Malinda et al., 1999). Tβ4 was only applied at the time of injury and at 48 h since after that the crust had formed. Visible macroscopic improvement was seen in the treated group by day 4. The study also found that Tβ4 promoted keratinocyte migration in vitro with activity in the picogram range. The findings were confirmed in various additional animal models (Table 1) and led to the clinical trials for hard to heal wound in patients as detailed in Table 2.

But returning hunters also need to share meat with their families and friends; this is where oxytocin comes into play. It can help overcome the potentially negative social effects of testosterone. Men who were absent for longer seem to need more oxytocin to reconnect with their families; it seems that absence does indeed make the heart grow fonder, via an oxytocin blast.
Exposure to ultraviolet (UV) light prompts an increased release of Alpha-MSH, which in turn stimulates the production of melanin in the skin. The more melanin produced the greater pigmentation level becomes, making the skin progressively darker and tan lasts significantly longer. This makes Melanotan peptide unique, people do not require as much exposure to UV light to produce more melanin, very attractive for people wishing to develop greater tanning of the skin in fastest way possible.
5-HTP increases a chemical in the brain. This chemical is called serotonin. Some medications used for depression also increase serotonin. Taking 5-HTP with these medications used for depression might cause there to be too much serotonin. This could cause serious side effects including heart problems, shivering, and anxiety.

Some of these medications used for depression include phenelzine (Nardil), tranylcypromine (Parnate), and others.
