Evidence for this role of oxytocin come from two types of experiments. First, infusion of oxytocin into the ventricles of the brain of virgin rats or non-pregnant sheep rapidly induces maternal behavior. Second, administration into the brain of antibodies that neutralize oxytocin or of oxytocin antagonists will prevent mother rats from accepting their pups. Other studies support the contention that this behavioral effect of oxytocin is broadly applicable among mammals.

Sexual activity has been found to stimulate the release of oxytocin, and it appears to have a role in erection and orgasm. The reason for this is not fully understood, but, in women, it may be that the increased uterine motility may help sperm to reach their destination. Some have proposed a correlation between the concentration of oxytocin and the intensity of orgasm.


I’ve used powdered 5-HTP a couple times now, it doesn’t taste great and it’s resulted in an unpleasant stomach upset that lasted 45–60 minutes. For that reason I’ll likely not continue to use it. I did not find it’s effect on mood remarkable enough that I would want to put up with the stomach upset. My go to Nootropics for mood are Rhodiola and Phenibut and my go to Biohacks for mood are meditation and no fap, I don’t feel the need to use a whole lot more mood promoting strategies.
Stimulation of milk ejection (milk letdown): Milk is initially secreted into small sacs within the mammary gland called alveoli, from which it must be ejected for consumption or harvesting. Mammary alveoli are surrounded by smooth muscle (myoepithelial) cells which are a prominant target cell for oxytocin. Oxytocin stimulates contraction of myoepithelial cells, causing milk to be ejected into the ducts and cisterns.
Down syndrome. Some research shows that giving 5-HTP to infants with Down syndrome might improve muscle and activity. Other research shows that it does not improve muscle or development when taken from infancy until 3-4 years of age. Research also shows that taking 5-HTP along with conventional prescription drugs does improve development, social skills, or language skills.

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.


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!

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.
It should be noted that, anecdotally, 5-HTP is said to reduce cravings for carbohydrates in particular. The serotonergic (related to serotonin) system plays a role in macronutrient selection particular in obese persons with a craving for carbohydrates[13] and enhancing serotonergic transmission is known to reduce these cravings.[14] Beyond this, depressed serotonergic tranmission (hypothalamus) is also implicated in increased eating and reduced satiety in general.[15]

The activity of the PAM enzyme system is dependent upon vitamin C (ascorbate), which is a necessary vitamin cofactor. By chance, sodium ascorbate by itself was found to stimulate the production of oxytocin from ovarian tissue over a range of concentrations in a dose-dependent manner.[23] Many of the same tissues (e.g. ovaries, testes, eyes, adrenals, placenta, thymus, pancreas) where PAM (and oxytocin by default) is found are also known to store higher concentrations of vitamin C.[24]
Oxytocin in a nine amino acid peptide that is synthesized in hypothalamic neurons and transported down axons of the posterior pituitary for secretion into blood. Oxytocin is also secreted within the brain and from a few other tissues, including the ovaries and testes. Oxytocin differs from antidiuretic hormone in two of the nine amino acids. Both hormones are packaged into granules and secreted along with carrier proteins called neurophysins.
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.

Three groups of mice were individually placed in cages with aggressive mice and experienced social defeat, a stressful experience for them. One group was missing its oxytocin receptors, essentially the plug by which the hormone accesses brain cells. The lack of receptors means oxytocin couldn't enter the mice's brain cells. The second group had an increased number of receptors so their brain cells were flooded with the hormone. The third control group had a normal number of receptors.
In the ER, the patient's heart rate was elevated, she was sweaty, and had some muscle spasms. The physician in the ER called Poison Control for guidance. Poison Control indicated that a drug interaction between 5-HTP and Zoloft was a likely cause of the patient's symptoms because they were consistent with a rare but serious condition (serotonin syndrome) that occurs when serotonin concentrations in the brain are too high. Poison Control recommended a sedative to decrease the patient's heart rate and improve the other symptoms. 

The matters under subsection 52E (1) of the Therapeutic Goods Act 1989 considered relevant by the delegate included: (a) the risks and benefits of the use of the substance; (b) the purposes for which a substance is to be used and the extent of use of a substance; (c) the toxicity of the substance; (d) the dosage, formulation, labelling, packaging and presentation of a substance; (e) the potential for abuse of a substance; and (f) any other matters that the Secretary considers necessary to protect public health.
In the experiments, an epithelial wound was made in the corneas of sedated rats. A Tb4 solution was applied at several concentrations to the injured eyes in one group of rats while another group was treated with a solution without Tb4. Following 12, 24 and 36 hours, the eyes were tested by microscopic observation for epithelial growth over the injured site. Investigators found the Tb4 accelerated corneal wound repair at doses of Tb4 similar to those found to repair skin wounds. When tested 24 hours after treatment, the rate of accelerated repair was proportional to the concentration of Tb4, with the highest dose (25 microgram) showing a threefold acceleration of epithelial cell migration, compared to untreated. Treatment with Tb4 showed anti-inflammatory effects, helping resolve the injury. An application to human cells in a model of human corneal cells in culture showed that Tb4 enhanced epithelial cell migration in vitro.
Established immortalized human PDLCs [22] that maintain the characteristics of primary PDLCs by transfecting human telomerase reverse transcriptase (hTERT) were used. These cell line were kindly provided by Professor Takashi Takata (Hiroshima University, Japan). Cells were cultured in α-MEM supplemented with 10% FBS, 100 U/mL penicillin, and 100 μg/mL streptomycin in a humidified atmosphere of 5% CO2 at 37°C. For the experiments, the cells were seeded into culture dishes and then cultured in α-MEM containing 10% FBS for 2 days until 70% confluent, and, then, the media was replaced by serum-free medium in order to minimize any serum-induced effects on PDLCs. Subsequently, the cells were exposed to H2O2 and human Tβ4 peptide (RegeneRx Biopharmaceuticals Inc., Rockville, MD). All treatments were performed in triplicate and approved by the local ethics committee.

Melanotan II was originally developed as a treatment for sexual dysfunction. However, this was abandoned when the metabolite bremelanotide was developed instead for treatment of haemorrhagic shock. Melanotan II is usually injected subcutaneously for the purposes of sunless tanning, appetite suppression, inducing sexual desire and penile erection and other conditions such as rosacea and fibromyalgia. There are also dose forms available for nasal administration. The therapeutic dose is considered to be 0.01 mg/kg.


One way to clarify that question is to give individuals oxytocin rather than just measure naturally occurring levels. In experiments by couple therapist and researcher Beate Ditzen at the University of Zurich, couples each sprayed a liquid containing oxytocin up their noses (which ensures that the hormone reaches the brain). Ditzen then got them to talk with each other about an issue that both partners said often lead to disagreement or fighting, such as who did the housework or how they spent their free time. She observed how they communicated with each other during the discussion compared with couples who didn’t get the hormone.

All of this becomes heavily ironic when you consider that the chemical in question – a hormone called oxytocin – is often billed as the “hormone of love”, and even marketed as “Liquid Trust”. As a new study shows, the reality is much more complicated. Describing oxytocin as the “hormone of love” is like describing a computer as a “writing tool” – it does other things too, some of which aren’t pleasant.
Melanotans include melanotan I (afamelanotide) and melanotan II. Both melanotan I and II are widely abused to obtain a cosmetic tan. The melanotans are potent, non-selective melanocortin receptor agonists affecting MC1, MC3, MC4 and MC5 receptors. These receptors are responsible for many physiological systems including: pigmentation, energy, sexual function, immune system, inflammation and the cardiovascular system.
Oxytocin's story starts back in the early 1900s, when biochemists discovered that a substance from the posterior pituitary gland could promote labour contractions and lactation. When scientists later discovered the hormone responsible, they named it oxytocin after the Greek phrase meaning 'rapid birth'. Oxytocin is produced mainly by the brain's hypothalamus; in the 1970s, studies revealed that oxytocin-producing neurons send signals throughout the brain, suggesting that the hormone had a role in regulating behaviour.

The N-terminal half of β-thymosins bears a strong similarity in amino acid sequence to a very widely distributed sequence module, the WH2 module. (Wasp Homology Domain 2 - the name is derived from Wiskott-Aldrich syndrome protein).[11][12] Evidence from X-ray crystallography shows that this part of β-thymosins binds to actin in a near-identical manner to that of WH2 modules, both adopting as they bind, a conformation which has been referred to as the β-thymosin/WH2 fold. β-thymosins may therefore have evolved by addition of novel C-terminal sequence to an ancestral WH2 module.[13] However, sequence similarity searches designed to identify present-day WH2 domains[14] fail to recognise β-thymosins, (and vice versa) and the sequence and functional similarities may result from convergent evolution.[15]
I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. I would say yes though. Just because you dont “know” or “feel” any injury, you might be one functional movement away from a weakened tendon or muscle – snap, crackle and POP! These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever.
For this study, one of us, Ben Trumble, followed Tsimane men as they went hunting for food. Typically, Tsimane men set out alone or with a partner in the early morning and search in the forest for prey such as wild pigs, deer, monkeys, or the rare tapir. Following long looping trails they might be gone for eight or nine hours, traveling about six miles (ten kilometers). Ben collected saliva samples throughout the hunt in order to measure changes in men’s hormone levels.
If you were to go on the internet, read the hype, you'd probably think it'll be something like having an ecstasy tablet or having an orgasm or something like that, but the reality is you probably wouldn't be able to distinguish it from placebo. So the effects are extremely subtle. Now, that subtlety isn't necessarily because of oxytocin itself being a subtle hormone, it's just this issue of it penetrating the brain. So when you take it intranasally, we're still trying to work out how much gets into the brain, but probably only a vanishingly small amount.

When practicing deep breathing, focus on a calmer state of mind as you distract yourself from overwhelming thoughts and sensations. Sit in a quiet area and practice the following: Take a slow, deep breath through your nose, allowing both your stomach and chest to rise. Once your stomach is fully expanded, breathe out through your mouth, just as slowly as when you were breathing in.


Despite this, Tβ4’s place on the banned-substances list is warranted. It reflects the possibility that the effects of the supplement may manifest as a tangible improvement in athletes. However, any time a journalist flippantly declares it “heals damaged tissue and speeds recovery”, it should be noted that such claims are a harmful distortion of the facts.

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."


On a personal note, 5-HTP is actually one of the 1st nootropics I ever used. When I was a teenager and would go to raves me and my friends would use 5-HTP the next day because ecstasy (MDMA) diminishes the serotonin levels. Anyone with much experience with ecstasy knows that the day(s) after can be pretty hellish because the drug so depletes your feel good neurotransmitters, 5-HTP is sort of a Biohack for this.
This article is authored by a PhD Candidate and her supervisory team at University of Queensland, and reflects the interests of the student’s doctoral project in undertaking the nation’s first qualitative study into experiences of Melanotan use among the general population. Dubbed ‘Project Melanotan’, the investigation aims to directly engage with ‘melanotanners’ in a non-judgemental environment, in an effort to both critically evaluate as well as understand lived experiences of melanotaning as they relate to conceptually relevant notions of risk, technology and the body.

Oxytocin is typically remembered for the effect it has on prosocial behaviors, such as its role in facilitating trust and attachment between individuals. Consequently, oxytocin is often referred to as the “love hormone".[73][qualify evidence] However, oxytocin has a more complex role than solely enhancing prosocial behaviors. There is consensus that oxytocin modulates fear and anxiety; that is, it does not directly elicit fear or anxiety.[74] Two dominant theories explain the role of oxytocin in fear and anxiety. One theory states that oxytocin increases approach/avoidance to certain social stimuli and the second theory states that oxytocin increases the salience of certain social stimuli, causing the animal or human to pay closer attention to socially relevant stimuli.[75]
Oxytocin is known as the hormone that promotes feelings of love, bonding and well-being. It's even being tested as an anti-anxiety drug. But new research shows oxytocin also can cause emotional pain. Oxytocin appears to be the reason stressful social situations, perhaps being bullied at school or tormented by a boss, reverberate long past the event and can trigger fear and anxiety in the future. That's because the hormone actually strengthens social memory in the brain.
"Just that it is completely false that these particular substances and the program wasn't discussed through the highest levels of the club. We have been very firm in terms of our belief in what ASADA, the AFL and Essendon know and for them to remotely suggest that no one knew, to be really blunt, is completely wrong and in some ways offending the process we set up at Essendon Football Club. We were very strict in the protocols we set up."
PDGF-BB (Mustoe et al., 1994), FGF-2 (Inadomi et al., 2004), IGF I and II (Zhao et al., 1995), TGF-β (Greenalgh, 1996), and L-arginine (Shi et al., 2003) enhance fibroblast proliferation and deposition of collagen in chronic wounds. Thymosin β4 accelerates wound repair in both young and old diabetic mice by significantly increasing wound contraction and collagen deposition. A synthetic peptide that duplicated the actin-binding domain of thymosin β4 promoted wound repair in aged mice to a degree comparable to that of the whole molecule (Philp et al., 2003). In rats with wound healing impaired by mitomycin C, the formation of granulation tissue (angiogenesis and fibroblast proliferation) was significantly advanced by hydrogel sheets composed of alginate, chitin/chitosan, and fucoidin (Murakami et al., 2010).
In December 2010, the delegate made a delegate only decision to include afamelanotide (also known as melanotan I) with a cross-reference to melanocyte stimulating hormone (MSH) for inclusion into the current Poisons Standard. It was noted that afamelanotide should not be confused with a similar substance commonly known as Melanotan-II, which is a cyclic lactam synthetic analogue of α-MSH. It was noted that melanotan-II was under investigation for treating sexual dysfunction, although this has been abandoned due to side effects associated with the immune and cardiovascular systems. Its metabolite, bremelanotide, is under investigation for treating haemorrhagic shock.

The PDLCs were pre-treated with Wnt5a siRNA (30 nM) or Wnt5 peptide (500 ng/mL) for 2 hours, post-incubated with Tβ4 peptide (1 μg/mL) and 200 μM H2O2 for 48 hours (A-E), and then conditioned medium (CM) was collected. The bar graph shows the fold increase in protein or mRNA expression compared with control. * Statistically significant differences compared with the control, p<0.05. # Statistically significant difference compared with the H2O2-treated group. The data presented were representative of three independent experiments.
“This is a very ancient molecule,” says Sue Carter, a neuroscientist at Indiana University in Bloomington, whose lab pioneered many of the early studies of oxytocin in voles. “It has been used and reused for many purposes across the evolution of modern animals, and almost everybody who's tried to look at an effect of oxytocin on anything like social behaviour has found something.”

This may be an odd question. But would this be good to inject or spray on those that have undergone hair transplants in the first month of surgery. Fue microscars. I see you mention it improves hair growth and blood flow. both which basically what rogaine claims to do. Surely this would benefit new transplanted hair follicles in taking and holding? Interested in your thoughts in the matter.
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.
