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]
Second, 5-HTP can cause serious drug interactions with many medications, especially those used to treat depression. Because antidepressants generally work by increasing serotonin in the brain, 5-HTP could combine with these medications to cause high concentrations of serotonin. Having too much serotonin can lead to serotonin syndrome, a serious condition characterized by dangerously high heart rate, blood pressure, and temperature. 5-HTP can interact with other classes of drugs, like migraine and pain medications, that also affect serotonin concentrations.
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).
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.
Dr Sohère Roked is a GP in the UK with a specialist interest in integrative medicine. She prescribes 5-HTP to patients with anxiety and depression, alongside vitamins and other natural supplements, and sees no problem with it being used for mild conditions. "With the patients I see, generally I've seen good results with it. Antidepressants do work for some people, so I'm not against them completely, but others don't want to go down that path straight away. This gives them another option."
Letdown reflex. In lactating (breastfeeding) mothers, oxytocin acts at the mammary glands, causing milk to be ‘let down’ into a collecting chamber, from where it can be extracted by compressing the areola and sucking at the nipple. Sucking by the infant at the nipple is relayed by spinal nerves to the hypothalamus. The stimulation causes neurons that make oxytocin to fire action potentials in intermittent bursts; these bursts result in the secretion of pulses of oxytocin from the neurosecretory nerve terminals of the pituitary gland.
Autism. A 1998 study found significantly lower levels of oxytocin in blood plasma of autistic children.[14] A 2003 study found a decrease in autism spectrum repetitive behaviors when oxytocin was administered intravenously.[15] A 2007 study reported that oxytocin helped autistic adults retain the ability to evaluate the emotional significance of speech intonation.[16]
Oxytocin is a versatile actor, whose resume includes all sorts of jobs in sex, reproduction, social behaviour and emotions.  It can increase trust among people and make them more cooperative (this works in meerkats, too). It can increase the social skills of autistic people. It’s released during orgasm. It affects lactating breasts, contracting wombs and the behaviour of sheep mothers towards their newly born lambs. The list goes on: drug addiction, generosity, depression, empathy, learning, memory.

Disclaimer: Thymosin Beta 4 is a peptide that should only be purchased for use in experimentation and research. It should not be purchased for human use or any other purpose than for research. It is advised that once purchased, the peptide is used within experimental circumstances that are under strict lab regulations. It is recommended that researchers use protective gear in order to prevent contact with the substance. However, if exposure is made with the peptide, it is very important to cleanse the area immediately to prevent harm.
Thymosin beta-4 is a very large molecule. In fact, it is so large that it cannot fit entirely into the receptor. Different sections of the molecule have different activities. TB-500 is the part of thymosin beta-4 hormone which promotes the most useful effects (overall healing, repair, new blood and muscle cells). For medical applications it is more practical to use the TB-500 instead of the entire Thymosin Beta-4 protein.

Thymosin Beta 4 is a peptide that was first found within the thymus gland. Since its discovery, other types of thymosin have been found in different tissues throughout test subjects. Thymosin Beta 4 is typically found in both types of muscles – skeletal (the muscles that are required to move) and smooth muscles (such as the heart). When damage occurs in a tissue, Thymosin Beta 4 is upregulated. Then when traumas take place, Thymosin Beta 4 is released in order to help the subject heal from the trauma. This peptide also helps to prevent adhesions from forming, which means there will be less scar tissue and potentially more flexibility. It has potent anti-inflammatory characteristics.
The mRNA and protein expressions were determined by PCR analysis (A) and Western blot analysis (B), respectively. The bar graph shows the fold increase in protein or mRNA expression compared with control cells * Statistically significant differences compared with the control, p<0.05. The data presented were representative of three independent experiments.
My mother was a mother of 6 born between 1948 and 1961. She was a great advocate for lots of cuddles and physical contact with all of her children (as was my dad). This included baby massage directly on the skin as she emphasised touch as being very important. She passed this knowledge onto me when I became an aunt and then a mother. I am very grateful to have had such a hands on, affectionate and intuitive mother as a role model.

Angiogenesis is an essential step in the repair process that occurs after injury. In this study, we investigated whether the angiogenic thymic peptide thymosin beta4 (Tbeta4) enhanced wound healing in a rat full thickness wound model. Addition of Tbeta4 topically or intraperitoneally increased reepithelialization by 42% over saline controls at 4 d and by as much as 61% at 7 d post-wounding. Treated wounds also contracted at least 11% more than controls by day 7. Increased collagen deposition and angiogenesis were observed in the treated wounds. We also found that Tbeta4 stimulated keratinocyte migration in the Boyden chamber assay. After 4-5 h, migration was stimulated 2-3-fold over migration with medium alone when as little as 10 pg of Tbeta4 was added to the assay. These results suggest that Tbeta4 is a potent wound healing factor with multiple activities that may be useful in the clinic.

But we have to be just as good at recognizing who we can trust, so the system needs fine-tuned control. That’s apparently where oxytocin comes in. The amygdala, that critical organ for our biological risk response, has a high concentration of receptors for oxytocin. In the second set of those gambling experiments with the volunteers and the trustees, researchers used fMRI to watch the brains of the volunteers as they made their choices. As the levels of oxytocin in the brain went up compared with the placebo group, activity in the amygdala went down! Oxytocin diminishes the amygdala’s ability to send out the message “Warning! Warning! I don’t trust this guy.”
During the 2000s, the Melanotan II peptide and the metabolite derived from it, the erectile dysfunction-focused Bremelanotide (also known as PT-141), were patented and then licensed to biotechnology companies hoping to develop them into profitable prescription drugs. However, these companies also offer the peptides for direct sale to researchers. These transactions occupy a legal gray area, since the peptides are banned for human use outside clinical trials. While they can be purchased from various websites specializing in research chemicals, the purchaser usually has to affirm prior to final sale that the peptide "will not be used for human consumption" and is being acquired for "research purposes only."
“The study was double-blinded and was for two consecutive 6-wk periods. No diet was prescribed during the first period, a 5040-kJ/d diet was recommended for the second. Significant weight loss was observed in 5-HTP-treated patients during both periods. A reduction in carbohydrate intake and a consistent presence of early satiety were also found. These findings together with the good tolerance observed suggest that 5-HTP may be safely used to treat obesity.”

However, the Food and Drug Administration and its equivalents in other countries have issued repeated advisory notices about Melanotan II, urging consumers to stop using and purchasing this unapproved product. David Carter of the United Kingdom's Medicines and Healthcare Products Regulatory Agency was unequivocal in his denunciation, warning would-be buyers against being "fooled into thinking that Melanotan offers a shortcut to a more even tan." Liverpool John Moores University researcher Michael Evans-Brown cautioned that the peptide may be linked to dyspepsia and various cardiovascular problems, such as increases in blood pressure, while others have noted it appears to stimulate the growth of moles on the body.
The hormone does not act alone. In 2013, neuroscientist Robert Malenka at Stanford University in California and his colleagues showed that oxytocin works together with the neurotransmitter serotonin to reduce the excitability of neurons in the nucleus accumbens9, a brain region involved in reward. This process seems to support the preference of mice to return to environments where they had rewarding social interactions with other animals. “Oxytocin is part of a system,” Carter says, “and it's not the only molecule that matters, but it's one that in some way is regulatory over a large number of other systems.”
The potential of Tb4 to repair sun damaged and aging skin is yet to be established by extensive studies. Many of the biological events that occur in wounding are involved in skin impaired by sun and aging. Ultraviolet radiation damage or other injuries to skin that are associated with aging may be in the future repairable with Tb4, similar to the success with wound repair. It is a hopeful prediction that this small anti-inflammatory molecule, which plays a vital role in regeneration, remodeling and healing of damaged tissues, would help rejuvenate aging skin. The effects of Tb4 in accelerating wound repair are important following surgery; Tb4 would then have practical applications following cosmetic surgery, a procedure growing in popularity in our society, in dealing with aging skin.
Milk ejection reflex/Letdown reflex: in lactating (breastfeeding) mothers, oxytocin acts at the mammary glands, causing milk to be 'let down' into subareolar sinuses, from where it can be excreted via the nipple.[47] Suckling by the infant at the nipple is relayed by spinal nerves to the hypothalamus. The stimulation causes neurons that make oxytocin to fire action potentials in intermittent bursts; these bursts result in the secretion of pulses of oxytocin from the neurosecretory nerve terminals of the pituitary gland.
In all groups, [intravenous tryptophan] impaired memory and psychomotor performance significantly. In conclusion, cognitive deficits in [bipolar patients] following [intravenous tryptophan] may reflect a central 5-HT vulnerability in frontal brain areas. Independent of [intravenous tryptophan], cognitive deficits in [bipolar patients] provide evidence for a trait marker for [bipolar disorders].
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.

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.

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.
In addition, in the Phase 1 clinical trial in healthy volunteers using a randomised, double-blind, placebo-controlled single- and multiple-dose Phase 1 clinical trial, the safety and pharmacokinetics of the intravenous administration of TB-4 was evaluated. From this, intravenous administration of TB-4 appears to be safe and well-tolerated by all subjects with no dose limiting toxicity or serious adverse events reported.
Good quality Griffonia Simplicifonia, however the pouch is a very inconvenient packaging choice! Why not use the small 25-50gm pill bottle type? I used to be a quality controller in food additives and it would be so perfect to take doses from and fairly cheap and easy to source. I can understand if this is a new product for your line however but you should invest in this for 5htp alone perhaps. Thank you though will be ordering more down the track!

Social behavior[66][111] and wound healing: Oxytocin is also thought to modulate inflammation by decreasing certain cytokines. Thus, the increased release in oxytocin following positive social interactions has the potential to improve wound healing. A study by Marazziti and colleagues used heterosexual couples to investigate this possibility. They found increases in plasma oxytocin following a social interaction were correlated with faster wound healing. They hypothesized this was due to oxytocin reducing inflammation, thus allowing the wound to heal more quickly. This study provides preliminary evidence that positive social interactions may directly influence aspects of health.[112] According to a study published in 2014, silencing of oxytocin receptor interneurons in the medial prefrontal cortex (mPFC) of female mice resulted in loss of social interest in male mice during the sexually receptive phase of the estrous cycle.[113] Oxytocin evokes feelings of contentment, reductions in anxiety, and feelings of calmness and security when in the company of the mate.[101] This suggests oxytocin may be important for the inhibition of the brain regions associated with behavioral control, fear, and anxiety, thus allowing orgasm to occur. Research has also demonstrated that oxytocin can decrease anxiety and protect against stress, particularly in combination with social support.[114] It is found, that endocannabinoid signaling mediates oxytocin-driven social reward.[115]
Sexual activity: The relationship between oxytocin and human sexual response is unclear. At least two uncontrolled studies have found increases in plasma oxytocin at orgasm – in both men and women.[103][104] Plasma oxytocin levels are notably increased around the time of self-stimulated orgasm and are still higher than baseline when measured five minutes after self arousal.[103] The authors of one of these studies speculated that oxytocin's effects on muscle contractibility may facilitate sperm and egg transport.[103]

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!
In addition to its intracellular role as the major actin-sequestering molecule in cells of many multicellular animals, thymosin β4 shows a remarkably diverse range of effects when present in the fluid surrounding animal tissue cells. Taken together, these effects suggest that thymosin has a general role in tissue regeneration. This has suggested a variety of possible therapeutic applications, and several have now been extended to animal models and human clinical trials.

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.


Secretion of oxytocin from the neurosecretory nerve endings is regulated by the electrical activity of the oxytocin cells in the hypothalamus. These cells generate action potentials that propagate down axons to the nerve endings in the pituitary; the endings contain large numbers of oxytocin-containing vesicles, which are released by exocytosis when the nerve terminals are depolarised.
How not surprising on one level that a hormone involved in the formation of primary bonds, those that can have serious impacts on your survival, would be discerning. After all, if you had a mother who was dangerous, abusive, etc., how counter productive would it be for you to bond so tightly to her that you were all over her all the time, increasing your chances of pissing her off and killing you. And, how beneficial for you to be more bonded to a mother figure who was good to you, and provided you with nurture.
In another study, published in PNAS in 2010, men were given a dose of oxytocin and asked to write about their mothers. Those with secure relationships described their moms as more caring after the hormone dose. Those with troubled relationships actually saw their mothers as less caring. The hormone may help with the formation of social memories, according to the study researchers, so a whiff strengthens previous associations, whether good or bad.
What we noticed was that all the rats that had received oxytocin straight into their brain immediately prior to being given alcohol, were up and moving about and seemed to be completely sober. Whereas all of the rats that had just been given the alcohol were, as we would predict from the dose that we were giving them, quite drunk. And so we thought, 'Wow, what's going on here?' It was almost as though the oxytocin was blocking the intoxicating effects of the alcohol.
I’ve tried researching this on my own but haven’t been able to find much. I have Hashimoto’s Thyroiditis & my endocrinologist says I barely have any thyroid left. Would TB-500 help regenerate new thyroid growth & if so where would I inject it?? I plan on taking this along with the BPC-157 (orally) for gut inflammation to see if it can repair leaky gut & digestive issues. Thoughts?
