Plain sterile water is the most suitable diluent for TB-500. Alternatively it can be reconstituted with sterile saline (0.9% NaCl) or sterile bacteriostatic water (0.9% sodium chloride). Plain sterile water should be readily available to buy without prescription in any local pharmacy. Alternatively it can also be purchased online. It is even available on ebay.

5-HTP appears to reduce food intake secondary to increasing satiety, although most studies are currently conducted in women (in regards to 5-HTP being related to serotonin, this may be relevant; see our creatine page and the Depression section for more information). At least one study that was mixed gender supports the notion it benefits both genders, however


So far, few studies have definitively linked autism to problems in oxytocin signalling. Some of the clearest evidence emerged in February, from a team led by neurogeneticist Daniel Geschwind of the University of California, Los Angeles. The group showed that mice that lacked a working copy of the Cntnap2 gene — which has been implicated in a small subset of human autism cases — had fewer oxytocin-containing neurons in the hypothalamus and socialized less with other mice than did control mice15. After receiving doses of oxytocin every day for two weeks, the mice behaved normally again. “Until this, there was no evidence that there was a subtype of autism that had to do with oxytocin deficits,” Geschwind says.


But what about the three-month warning? Dr Rush, while an advocate for the supplement, sees it as a short-term solution, and not something to rely on long-term, for good reason. "Technically taking 5-HTP alone can deplete important brain chemicals such as dopamine and adrenaline. While 5-HTP is aimed at increasing the amount of serotonin in the body, dopamine and adrenaline are also important for positive mental health states. In order to prevent the depletion of important brain chemicals, taking 5-HTP would need to be balanced with amino acids that support the production of dopamine and adrenaline." That's L-Tyrosine, which you eat in soy, chicken and beef, and can also be found in health food shops as a supplement.
Thank you for this important segment. i have read books that mention oxytocin along with other brain chemicals, if levels are low in the brain it will cause problems, of course, makes sense. low brain neurotransmitters can be restored by using amino acids (supplements) eg: tryptophan will increase serotonin and cure depression without the use toxic pharmaceutical drugs that don.t work.
Kim found that when Americans who carry a particular version of the OXTR gene are more likely to turn to their friends for support when they are distressed. But Koreans react to social stress in a different way – for them, it’s less socially acceptable to turn to friends for support during tough times. And distressed Koreans who carry the same version of OXTR are less likely to seek support from their friends.
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.

You can't purchase oxytocin spray at any retail outlet and as our experts made clear in the program, buying a product online gives you no guarantee of what is actually in the product - it could be oxytocin or it could be something else - nor is it proven that the spray will actually reach your brain. For these reasons, none of our experts recommend purchasing oxytocin spray.
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]
Increasing trust and reducing fear. In a risky investment game, experimental subjects given nasally administered oxytocin displayed “the highest level of trust” twice as often as the control group. Subjects who were told that they were interacting with a computer showed no such reaction, leading to the conclusion that oxytocin was not merely affecting risk-aversion.11 Nasally administered oxytocin has also been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses).12 There is no conclusive evidence for access of oxytocin to the brain through intranasal administration, however.
The biologically active form of oxytocin, commonly measured by RIA and/or HPLC techniques, is also known as the octapeptide "oxytocin disulfide" (oxidized form), but oxytocin also exists as a reduced straight-chain (non-cyclic) dithiol nonapeptide called oxytoceine.[120] It has been theorized that oxytoceine may act as a free radical scavenger, as donating an electron to a free radical allows oxytoceine to be re-oxidized to oxytocin via the dehydroascorbate / ascorbate redox couple.[121]

Supplements haven't been tested for safety and due to the fact that dietary supplements are largely unregulated, the content of some products may differ from what is specified on the product label. Also keep in mind that the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. You can get tips on using supplements, but if you're considering the use of 5-HTP supplements, talk with your primary care provider first. Self-treating a condition and avoiding or delaying standard care may have serious consequences.
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.
It turns out oxytocin is responsible for a lot more than just love. New science has found that this amazing molecule also influences how sociable each of us is, allowing us to 'tune in' to the social information around us, perceiving it in much higher resolution. Scientists are now applying this new knowledge in the lab, and as reporter Dr Graham Phillips finds out, they're discovering oxytocin's great potential to treat social disorders, like drug addiction and alcoholism.

Chae, H. S., Kang, O. H., Choi, J. G., Oh, Y. C., Lee, Y. S., Jang, H. J., Kim, J. H., Park, H., Jung, K. Y., Sohn, D. H., and Kwon, D.

Young says that the oxytocin field would benefit from closer collaboration between basic and clinical researchers. If basic scientists can work out how oxytocin helps the brain to process social stimuli, then that might help in the design of stimuli — in the form of behavioural therapies — that could be given alongside the hormone to change behaviour, just as oxytocin and pup calls together affect virgin mice. “I think in the future these two branches need to have more communication,” Young says.
It bears understanding that this type of peptide is not a treatment or cure for anything, nor should it be considered a preventative measure to skin cancer. While this tanning peptide is known to protect the skin through the natural tanning process, it is not in and of itself a foolproof UV shield, however it is an excellent way for those who don't tan otherwise to get rich golden tans without as much exposure to the sun.
The product can be of unknown quality and subject to contamination and stability concerns with use of multi-dose vials. There is no experience with the product other than through unregulated channels. There are health risks from the substance itself and its route of administration – documented in medical literature, case reports as well as reports from NSW PIC.
TB-500 and Thymosin Beta-4 are not exactly the same, although you’ll often see the two names used interchangeably in the peptide world (AKA broscience bodybuilding forums).  It’s much harder to get your hands on true Thymosin Beta-4, whether for research use, equine enhancement, athletic performance enhancement or bodybuilding. But TB-500’s peptide sequence shares most of the properties of Thymosin Beta-4, and it’s more economical to produce, thus easier to find.
Oxytocin is a peptide of nine amino acids (a nonapeptide). The sequence is cysteine - tyrosine - isoleucine - glutamine - asparagine - cysteine - proline - leucine - glycine (CYIQNCPLG). The cysteine residues form a sulfur bridge. Oxytocin has a molecular mass of 1007 daltons. One international unit (IU) of oxytocin is the equivalent of about 2 micrograms of pure peptide.

When you get your TB-500, it will come in a powder form. Just like BPC-157, you will need to “reconstitute” it by adding bacteriostatic water. Go back and read my article on BPC-157 to get access to a peptide calculator that will help you with the mixing/dosage math. Once your TB-500 is properly mixed, you then draw the dose into an insulin syringe, and inject it intramuscularly, subcutaneously, or intravenously (according to your preference).


5-HTP has been investigated for its role in hot flashes as Selective Serotonin Reuptake Inhibitors (SSRIs) have been noted to reduce the occurrence of hot flashes and menopausal symptoms.[30][31] In a study in menopausal females given 150mg 5-HTP daily (50mg taken thrice a day) for a period of one week failed to quantitivatively reduce the occurrance of hot flashes[32] as assessed by a Flashmark Pro recording device.[33]
Hey Adrian, thanks for reaching out. Firstly, I am not a doctor and nothing I say should be taken as medical advice. For something like this I suggest you book a consult at
A handful of large-scale clinical trials are now getting under way to test oxytocin and oxytocin-based therapies for autism spectrum disorder, and to work out who could benefit. Linmarie Sikich, a child psychiatrist at the University of North Carolina is heading the largest of these trials. Sikich plans to recruit 300 people with autism spectrum disorder, ranging in age from 3 to 17, and give them 6 months of either oxytocin or a placebo, followed by 6 months in which everyone will receive oxytocin.
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].
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.

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.


Recently, therapeutic biomolecules such as growth factors provide great potential as an alternative therapeutic approach to traditional periodontal wound healing [61]. However, because of the short half-lives of growth factors and polynucleotides in the body and the necessity to deliver to specific target sites, those medicinal substances do not always exhibit the anticipated therapeutic potency and outcomes [62]. Thus, optimized delivery regimes and well-defined release kinetics appear to be logical prerequisites for safe and efficacious clinical application of biomolecules. For considering the application of Tβ4 in clinical trials, target cells of exogenous Tβ4 should be restricted to cells in the periodontal tissue.
If the two things you can't live without are a dark, even tan and a fast-acting, long-lasting erection, then add Melanotan II to your holiday shopping list. This synthetic peptide hormone, which was developed by a research team at the University of Arizona during the late 1990s, darkens skin pigment and may stimulate erectile activity. And despite continued concern and controversy within the medical community regarding its use, it remains available for sale over the internet in a powdered form that can then be reconstituted for subcutaneous injections.
There have been some side effects reported while using Melanotan 2, typically these effects appear during the first few days of dosing and will become increasingly less obvious as the body adjusts to the peptide. These effects include: nausea, appetite loss, drowsiness and increased sex drive. In order to combat nausea, an anti-histamine can be taken when injecting until the body gets used to it. But most common way to deal with this is to inject Melanotan before bed, this is also beneficial to combat any drowsiness.
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
Serotonin appears to be associated with panic attacks. Although studies that have used tryptophan depletion techniques in humans do not necessarily induce a panic attack[34][35][36] it appears it may sensitize the body by an increase in neurovegetative panic symptoms and increased anxiety[37] which suggests that serotonin is protective against panic attacks, at least acutely.[38][39] A study in 24 unmedicated panic disorder patients and normal participants given 200mg 5-HTP prior to a 35% CO2 test (used to induce a panic attack-like response) noted that the test was able to induce panic attack in both panic disorder patients and normal persons and that 200mg 5-HTP was protective in both conditions but to a greater degree in persons suffering from panic disorders.[40] This has been replicated with cholecystokinin-4 induced panic attack with 200mg 5-HTP in otherwise healthy persons.[41]
Oxytocin secreted from the pituitary gland cannot re-enter the brain because of the blood-brain barrier. Instead, the behavioral effects of oxytocin are thought to reflect release from centrally projecting oxytocin neurons, different from those that project to the pituitary gland. Oxytocin receptors are expressed by neurons in many parts of the brain and spinal cord, including the amygdala, ventromedial hypothalamus, septum and brainstem.
But long before that, say researchers, oxytocin could use a rebranding. “It doesn't induce love; it doesn't induce massive amounts of trust,” Guastella says. “The problem we've got ourselves into is that we're trying to look for a simple answer: either oxytocin does or does not work in a patient population, or it does or does not enhance a certain social process.”
Showa Denko, the source of up to 60% of all the tryptophan sold in the United States, had used an untested manufacturing process that reduced the amount of activated charcoal used to filter fermented raw tryptophan. Some reports suggest that purity may be a potential problem for 5-HTP as well. No cases of EMS resulting from 5-HTP use have been reported, however.
In a study measuring oxytocin serum levels in women before and after sexual stimulation, the author suggests it serves an important role in sexual arousal. This study found genital tract stimulation resulted in increased oxytocin immediately after orgasm.[105] Another study reported increases of oxytocin during sexual arousal could be in response to nipple/areola, genital, and/or genital tract stimulation as confirmed in other mammals.[106] Murphy et al. (1987), studying men, found oxytocin levels were raised throughout sexual arousal with no acute increase at orgasm.[107] 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 these changes "may simply reflect contractile properties on reproductive tissue".[108]
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.
Oxytocin affects social distance between adult males and females, and may be responsible at least in part for romantic attraction and subsequent monogamous pair bonding. An oxytocin nasal spray caused men in a monogamous relationship, but not single men, to increase the distance between themselves and an attractive woman during a first encounter by 10 to 15 centimeters. The researchers suggested that oxytocin may help promote fidelity within monogamous relationships.[109] For this reason, it is sometimes referred to as the "bonding hormone". There is some evidence that oxytocin promotes ethnocentric behavior, incorporating the trust and empathy of in-groups with their suspicion and rejection of outsiders.[66] Furthermore, genetic differences in the oxytocin receptor gene (OXTR) have been associated with maladaptive social traits such as aggressive behavior.[110]

This sounds very promising and I have a question I’m sure you haven’t heard before. It’s regarding healing. I’m about 230 and avid lifter as well as running occasionally. But I’ve had severe injuries to my l3-s1 for years a d yes I’ve tried some stuff before as far as lifting. But when I was 2 I had encephalitis. I survived it back in 74 which most didn’t however the treatment had left me with migraines and seizures as a child and was told my adult teeth would be very weak when they grew in. So I’m 44 and most of my teeth have broken and I’ve been looking for alternatives to implants. You said both the products mentioned in this article would improve healing and I’ve heard stem cells are capable of regrowing teeth. Would this work for me and how or where would I inject it or maybe do a oral form and let it sit in my mouth for a bit? Never really thought about this but I’ve tried so many clinical trials and been turned down each time. Any info would be greatly appreciated thank you in advance.

The oxytocin peptide is synthesized as an inactive precursor protein from the OXT gene.[18][19][20] This precursor protein also includes the oxytocin carrier protein neurophysin I.[21] The inactive precursor protein is progressively hydrolyzed into smaller fragments (one of which is neurophysin I) via a series of enzymes. The last hydrolysis that releases the active oxytocin nonapeptide is catalyzed by peptidylglycine alpha-amidating monooxygenase (PAM).[22]
In November 2008, the UK Medicines and Healthcare products Regulatory Agency (MHRA) warned the public against melanotan use stating it was an unlicensed medicine that may not be safe. As such, it is illegal to market or supply this product in the UK due to its unlicensed nature. Additionally the MHRA warned 18 companies about selling or advertising the product and closed down 72 websites involving melanotan. By 2013, the MHRA had received 18 reports of 74 separate reactions to the products and reactions have involved stomach and heart problems, as well as blood and eye disorders.

Oxytocin was also correlated with the longevity of a relationship. Couples with the highest levels were the ones still together six months later. They were also more attuned to each other than the low-oxytocin couples when Feldman asked them to talk about a shared positive experience. The high-oxytocin couples finished each other’s sentences, laughed together and touched each other more often. Feldman says it’s still not clear whether oxytocin was responsible for the stability of the couple’s bond six months later or if couples who weren’t as connected failed to trigger the oxytocin system.
The 10mg powder takes up about 5% of the bag it comes it, meaning you get a greater volume of the powder on your hand than in the spoon your using to find the powder at the bottom of the package. Since dosages are really small, I imagine most of the powder will be wasted. Also the 5-htp powder doesn't seem to dissolve or mix with liquids making it difficult to take. Other than the terrible packaging, the powder itself seems to be of good quality. Recommend it be repackaged in a bag 1/10th of the size, or alternatively, buy the capsules.
The studies that have been conducted have determined that this peptide is potent and that it occurs totally naturally. It does help to repair wounds using its anti-inflammatory characteristics. Unlike with growth factors and other repair factors, this peptide increases the migration of endothelial and keratinocyte. It also does not conjoin to extracellular matrixes and is noted as having a molecular weight that is very low, which enables it to travel far distances within tissues.
Conclusions:  Melanotan not a treatment or cure for anything.  Nor should it be considered a preventative treatment for skin cancer.  Despite this tanning peptide being known to protect the skin through the natural tanning process, it is not in and itself a guaranteed full proof UV shield.  However, it is a great way for those who don't tan easily to get sun-kissed all year long with minimal exposure to the sun.
Reconstituting tanning peptide is a part of the process required for use of the product and will require full attention to get proper results. 1 or 2ml sterile water is usually used, diluting with more water will improve dosing accuracy. Lovemelanotan peptide calculator is ideal tool for anyone just starting out and not sure how to reconstitute or dose the product properly.

Other supplements are available which have appetite supressant and mood enhancing effects similar to 5-HTP. These type of ingredients are often included, in optimal pre-formulated dosages in fat burners. Phenylethylamine is also another ingredient with mood enhancing potential that is often found in fat burners in place of 5-HTP. 5-HTP can be found in some sleep supplements, though in Australia they are replaced by ingredients such as GABA and phenibut.
For decades, 5-HTP has been recognized as important to appetite regulation. Higher levels of serotonin are linked to diminished appetite. Keeping serotonin levels from dipping can help keep appetite in check, and may help reduce cravings for carbohydrates. As a serotonin booster, 5-HTP may help to suppress appetite. Research indicates that 5-HTP may be effective in helping people who are overweight or obese lose weight.
