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.

TB-500 is a synthetic version of the naturally occurring peptide present in virtually all human and animal cells, Thymosin Beta-4. This potent peptide is a member of a ubiquitous family of 16 related molecules with a high conservation of sequence and localization in most tissues and circulating cells in the body. TB-500 not only binds to actin, but also blocks actin polymerization and is the actin-sequestering molecule in eukaryotic cells.


Do not fall for the easier methods of using MT-2, injections is the only proper way of using this peptide. Many Internet suppliers will sell things like nasal sprays, pre-mixed peptide, oral pills and powders, they simply don't work, if they did no one would use injections, right? There are a some positive reports of nasal spray experience, however its not very cost effective as peptide molecules in this form are large and difficult to pass the nasal membrance, there is some effect, but its minor comparable to injection route where absorption rate is 100%. Similarly, pills of this type are also quite useless because enzymes within the stomach will render the peptide inert.
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.
Myocardial infarction and heart failure are severe causes for death in humans. Extracellular nucleotides (ATP and ADP) released at the site of myocardial damage induce thrombosis, apoptosis and necrosis. ENTPD1 (ectonucleoside triphosphate diphosphohydrolase 1, CD39) rapidly hydrolyzes ATP and ADP to AMP. An in vivo myocardial ischemia/reperfusion injury test in transgenic mice expressing human CD39 resulted in a decrease of the infarct size. The same transgene including the human CD39 cDNA driven by the murine MHC class I gene H-2Kb promoter was used for the generation of transgenic pigs via SCNT. Expression of human CD39 was detected on circulating blood cells and in myocardial tissue of the transgenic animals. After in vivo induction of myocardial ischemia/reperfusion injury, a reduction of the myocardial injury analogous to the results in the transgenic mice was found (Wheeler et al., 2012).
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.

There is no long-term side effects ever reported, but there is post injection effects 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: hot flush in face, mild nausea, decreased appetite, and increased sex drive. In order to combat nausea, an anti-histamine product can be taken until the body gets used to it. But most common way to deal with this is to take the dose before bed.

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.


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.

TBI patients frequently suffer from long-term deficits in cognitive and motor performance. No single animal model can adequately mimic all aspects of human TBI owing to the heterogeneity of clinical TBI.11 Some features of cognitive and motor function in humans have been successfully demonstrated in experimental brain trauma models.28-30 The controlled cortical impact (CCI) model is one of the most widely used TBI models. The CCI-TBI model has many clinically relevant features in that CCI causes not only cortical damage but also selective neuronal death in the hippocampus in rodents, leading to sensorimotor dysfunction and spatial learning and memory deficits, respectively.18,31-33

Osteoclast differentiation was assessed by tartrate-resistant acid phosphatase (TRAP) staining and activity. After 5 days of culture, cells were stained for TRAP kit using a leukocyte acid phosphatase kit (Sigma Aldrich, St Louis, MO, USA). Cells with three or more nuclei were counted as multinucleated mature osteoclasts. To measure TRAP activity, cells were fixed with 10% formalin for 10 min and 95% ethanol for 1 min, and then 100 μl of citrate buffer (50 mM, pH 4.6) containing 10 mM sodium tartrate and 5 mM p-nitrophenylphosphate (Sigma-Aldrich) was added to the wells containing fixed cells in the 48-well plates. After incubation for 1 h, enzyme reaction mixtures in the wells were transferred to new plates containing an equal volume of 0.1 N NaOH. Absorbance was measured at 410 nm using a microplate reader.
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.

It turns out the love hormone oxytocin is two-faced. Oxytocin has long been known as the warm, fuzzy hormone that promotes feelings of love, social bonding and well-being. It's even being tested as an anti-anxiety drug. But new Northwestern Medicine® research shows oxytocin also can cause emotional pain, an entirely new, darker identity for the hormone.
To untangle the ways different hormones together influence behavior in more naturalistic contexts, we worked with the Tsimane people in Bolivia. Traditional societies like the Tsimane are not living relics of the past, but their lifeways – small, tight-knit communities that produce their own food – can reveal the kinds of situations our hormone systems are well adapted to.
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.
A study published last year in Biological Psychiatry was the first to assess whether people with variations in their oxytocin-receptor gene have a harder time maintaining romantic relationships than those who don’t. Hasse Walum, a graduate student at Karolinska Institute in Stockholm, and his colleagues took advantage of Swedish twin studies that included thousands of participants, their genetic information and their answers to questions about how affectionate they were with their romantic partners. They found that women with a specific variation weren’t as close to their partners as women without it: they kissed their partners less and didn’t desire physical proximity as often. These women were also more likely to report having had a marital crisis. Although researchers don’t know exactly how this variation affects the oxytocin system, it may result in a lower number of oxytocin receptors in the brain. People with fewer receptors would be less sensitive to the hormone’s effects.
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.

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]
Although Tβ4 contains only 43 amino acids, it appears to have a wide range of regenerative activities and specific sites on the molecule have been shown to mediate these effects (Goldstein & Kleinman, 2015; Sosne, Qiu, Goldstein, & Wheater, 2010). Both chemically synthesized and recombinant forms have shown efficacy for dermal healing in preclinical models and in human patients (Ehrlich & Hazard, 2012; Kim & Kwon, 2014, 2015; Malinda et al., 1999; Philp, Badamchian, et al., 2003; Philp & Kleinman, 2010; Philp et al., 2006; Ti et al., 2015; Treadwell et al., 2012). A dimeric form has been found to accelerate the rate of dermal healing in an animal model more rapidly than that of the parent molecule (Xu et al., 2013). Tβ4 has also shown repair and regenerative activity in a number of other injury models, such as traumatic brain injury, spinal cord injury, stroke, a model of multiple sclerosis, ischemic limbs, and cardiac damage due to ischemia (Bock-Marquette, Saxena, White, Dimaio, & Srivastava, 2004; Cheng, Kuang, Zhang, Ju, & Wang, 2014; Dube, Bollini, Smart, & Riley, 2012; Morris, Chopp, Zhang, Lu, & Zhang, 2010; Morris et al., 2014; Philp & Kleinman, 2010; Postrach et al., 2014; Smart et al., 2007; Sopko et al., 2011; Ti et al., 2015, Wang et al., 2012; Wei, Kim, Li, Wu, & Gupta, 2014; Xiong, Mahmood, Meng, et al., 2011; Zhang, Zhang, Morris, et al., 2009; Zuo et al., 2013). The processes and pathways for Tβ4-mediated repair are similar in these various tissues and support the observed promotion of dermal healing.
Robert Love, a urologist in Dallas, understands why there is such back-channel demand for a product like Melanotan II. "People sometimes want to handle performance issues on their own, without a physician involved, either because they are embarrassed or because they may be uninsured or lack adequate insurance," he told Motherboard. "Handling things this way is not advisable. We have prescription drugs that address erectile dysfunction issues. And although this isn't my area, there are alternative ways of getting suntans—tanning beds, spray tans—though of course extended outdoor sun exposure should be avoided if possible."
Although obtaining Melanotan II and Bremelanotide is relatively easy to do, both substances come in powder form and then must be reconstituted using sterile water prior to subcutaneous injection—a method of administration that can cause lead to skin bruising, cross-contamination, or infection, if the person performing the injection is inexperienced and the syringe isn't clean.
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]
