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.
The logic behind this trend is that creating tanned skin (by increasing melanin) with minimal to no sun exposure could protect individuals from skin damage, and even potentially lower melanoma risk. More melanin means more protection from UV radiation, and therefore a healthier (and conveniently, deeper) complexion. In this sense, there is perhaps a kernel of truth to the idea of the “healthy glow”.

In the prairie vole, oxytocin released into the brain of the female during sexual activity is important for forming a pair bond with her sexual partner. Vasopressin appears to have a similar effect in males.[57] Oxytocin has a role in social behaviors in many species, so it likely also does in humans. In a 2003 study, both humans and dog oxytocin levels in the blood rose after five to 24 minutes of a petting session. This possibly plays a role in the emotional bonding between humans and dogs.[58]
Researchers often investigate the effects of hormones on behavior in laboratory experiments with student subjects. Some studies show that when you give people oxytocin they become more generous and trusting. In others that administer testosterone to men, the opposite happens. The strength of such studies is that they can demonstrate cause and effect – the behavior change only occurs in subjects receiving hormones, not in those who get a placebo. But this research has weaknesses as well: it often focuses on single hormones, ignoring their potential interactions, and behavior is measured with highly artificial tasks.
"There was no substance labelled unfit for human use so anyone that tries to bandy that comment around apart from the fact the comment is totally false, we are now starting to accrue our legal case against people that have suggested as such. Under no circumstances was anything ever injected or given to a player which was unfit for human consumption," Dank told ABC News Radio on Sunday.
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.
There is one glaring problem, however: the supplements come with a disclaimer that recommends not taking them for more than three months. Most of the information out there on 5-HTP is anecdotal, and most of them are stories of it helping people, rather than hard facts about its scientific properties. I approached neurologists, psychologists and experimental doctors about 5-HTP, and many responses were strange. Not many people were willing to speak about it, saying they weren't qualified or hadn't read the relevant material, but there isn't much material to speak of. The main source of legitimate scientific evidence came from the University of Maryland Medical Center website, who stated that 5-HTP may work as well as certain antidepressant drugs to treat people with mild-to-moderate depression. But all the studies that support that statement were done in the 1980s and 1990s. I wanted to know if 5-HTP was a realistic alternative to SSRIs. Could I stay on 5-HTP forever, basking in its natural glory?
Bonding. In the Prairie Vole, oxytocin released into the brain of the female during sexual activity is important for forming a monogamous pair bond with her sexual partner. Vasopressin appears to have a similar effect in males.[13] In people, plasma concentrations of oxytocin have been reported to be higher amongst people who claim to be falling in love. Oxytocin has a role in social behaviors in many species, and so it seems likely that it has similar roles in humans.
Thymosin beta-4 (Tβ4) is a water-soluble, 43-amino acid, and 4.9 kDa protein that was originally isolated from bovine thymus [6]. Since Tβ4 is the major actin-sequestering molecule in eukaryotic cells and is found in all cells [7], Tβ4 has multiple diverse cellular functions, including tissue development, migration, angiogenesis, and wound healing [7]. We previously reported that Tβ4-overexpressing transgenic mice, using a construct on the skin-specific keratin-5 promoter, have abnormal tooth development and enhanced stimulation of hair growth [8]. Moreover, exogenous Tβ4 has anti-inflammatory effects in the bleomycin-induced mouse model of lung fibrosis [9], tooth extraction sockets in rats [10], rat model of myocardial ischemia [11], corneal wound healing [12], wound healing of rat palatal mucosa [13], in vitro model of cultured human gingival fibroblasts [14], and cardiac fibroblasts [15]. However, the effects of Tβ4 over expression or inhibition on differentiation are controversial. Exogenous β4 peptide inhibited osteogenic differentiation but facilitated adipogenic differentiation in human bone marrow-derived-mesenchymal stem cells (MSCs) [16]. In contrast, Tβ4 inhibition by Tβ4 siRNA attenuated odontoblastic differentiation in the odontoblast-like cells, MDPC-23 [17]. Moreover, we recently demonstrated that odontoblastic differentiation was enhanced by activation of Tβ4 by Tβ4 peptide but was decreased by Tβ4 siRNA in human dental pulp cells (HDPCs) [18]. However, the effects of Tβ4 on osteoclastic differentiation have not been reported.

Treatment with thymosin beta 4 (Tβ4) reduces infarct volume and preserves cardiac function in preclinical models of cardiac ischemic injury. These effects stem in part from decreased infarct size, but additional benefits are likely due to specific antifibrotic and proangiogenic activities. Injected or transgenic Tβ4 increase blood vessel growth in large and small animal models, consistent with Tβ4 converting hibernating myocardium to an actively contractile state following ischemia. Tβ4 and its degradation products have antifibrotic effects in in vitro assays and in animal models of fibrosis not related to cardiac injury. This large number of pleiotropic effects results from Tβ4’s many interactions with cellular signaling pathways, particularly indirect regulation of cellular motility and movement via the SRF–MRTF–G-actin transcriptional pathway. Variation in effects and effect sizes in animal models may potentially be due to variable distribution of Tβ4. Preclinical studies of PK/PD relationships and a reliable pharmacodynamic biomarker would facilitate clinical development of Tβ4.
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]
Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours and then incubated with 200 μM H2O2 for 48 hours (A, B). The mRNAs expression was examined by RT-PCR analysis. This data were representative of three independent experiments. The bar graph shows the fold increase in mRNA expression compared with control cells. * Statistically significant differences compared with the control, p<0.05.
Injected oxytocin analogues are used to induce labour and support labour in case of non-progression of parturition. It has largely replaced ergotamine as the principal agent to increase uterine tone in acute postpartum haemorrhage. Oxytocin is also used in veterinary medicine to facilitate birth and to increase milk production. The tocolytic agent atosiban (Tractocile®) acts as an antagonist of oxytocin receptors; this drug is registered in many countries to suppress premature labour between 24 and 33 weeks of gestation. It has fewer side-effects than drugs previously used for this purpose (ritodrine, salbutamol and terbutaline).
Affecting generosity by increasing empathy during perspective taking: In a neuroeconomics experiment, intranasal oxytocin increased generosity in the Ultimatum Game by 80%, but had no effect in the Dictator Game that measures altruism. Perspective-taking is not required in the Dictator Game, but the researchers in this experiment explicitly induced perspective-taking in the Ultimatum Game by not identifying to participants into which role they would be placed.[89] Serious methodological questions have arisen, however, with regard to the role of oxytocin in trust and generosity.[90] Empathy in healthy males has been shown to be increased after intranasal oxytocin[88][91] This is most likely due to the effect of oxytocin in enhancing eye gaze.[92] There is some discussion about which aspect of empathy oxytocin might alter – for example, cognitive vs. emotional empathy.[93] While studying wild chimpanzees, it was noted that after a chimpanzee shared food with a non-kin related chimpanzee, the subjects' levels of oxytocin increased, as measured through their urine. In comparison to other cooperative activities between chimpanzees that were monitored including grooming, food sharing generated higher levels of oxytocin. This comparatively higher level of oxytocin after food sharing parallels the increased level of oxytocin in nursing mothers, sharing nutrients with their kin.[94]
It has been reported that deficiencies in the amino acid tryptophan (precursor to 5-HTP) are correlated with depression, as evidence by serum tryptophan in depressed persons.[16][17] Decreased levels of tryptophan in the body can come from various means but are most likely caused by a diet lacking in the amino acid as substrate, or by upregulation of enzymes (most notably indoleamine 2,3-dioxygenase(IDO) and tryptophan 2,3-dioxygenase(TDO)) that degrade tryptophan or direct it to paths that are not serotonin synthesis causing a relative deficiency.[18][19] These enzymes can be upregulated in states of chronic inflammation[18][20] and injection of some pro-inflammatory cytokines has been implicated in depression[21] and increasing the kyurenine:tryptophan ratio, which is indicative of IDO activity being increased.[22] The activity of tryptophan hydroxylase can also be further downregulated in cases of Magnesium or vitamin B6 deficiency, stress, or excessive tryptophan levels.[7]
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 soluble form of Ac-SDKP peptide, derived from thymosin beta-4, has been described as a natural inhibitor of pluripotent hematopoietic stem cell proliferation and as a stimulator of angiogenesis, both in vitro and in vivo (Koutrafouri et al., 2001; Wang et al., 2004). This peptide has been selectively bound to acrylated hyaluronic acid hydrogels via thiol groups from cysteine residues (Song et al., 2014). Unfortunately, the immobilization process was poorly characterized and the effect of hydrogels on EC function was not tested in vitro. In a mouse model of chronic myocardial infarction, hydrogels with immobilized Ac-SDKP did not show improved regeneration potential. Yet, Ac-SDKP-HA hydrogels with entrapped stem cell homing factor SDF-1 showed a significant increase of myocardial regeneration and recovery of heart function, as compared to groups with only one or none of these factors, suggesting a potentially interesting synergistic effect.


Oxytocin is not only correlated with the preferences of individuals to associate with members of their own group, but it is also evident during conflicts between members of different groups. During conflict, individuals receiving nasally administered oxytocin demonstrate more frequent defense-motivated responses toward in-group members than out-group members. Further, oxytocin was correlated with participant desire to protect vulnerable in-group members, despite that individual's attachment to the conflict.[64] Similarly, it has been demonstrated that when oxytocin is administered, individuals alter their subjective preferences in order to align with in-group ideals over out-group ideals.[65] These studies demonstrate that oxytocin is associated with intergroup dynamics. Further, oxytocin influences the responses of individuals in a particular group to those of another group. The in-group bias is evident in smaller groups; however, it can also be extended to groups as large as one's entire country leading toward a tendency of strong national zeal. A study done in the Netherlands showed that oxytocin increased the in-group favoritism of their nation while decreasing acceptance of members of other ethnicities and foreigners.[66] People also show more affection for their country's flag while remaining indifferent to other cultural objects when exposed to oxytocin.[67] It has thus been hypothesized that this hormone may be a factor in xenophobic tendencies secondary to this effect. Thus, oxytocin appears to affect individuals at an international level where the in-group becomes a specific "home" country and the out-group grows to include all other countries.
Few forms of trust are more basic than that between a newborn and its mother. Scientists have discovered that this relationship is strengthened by the hormone oxytocin, released when the baby stares up at mom while breast feeding. Staring lovingly at your boyfriend or girlfriend can trigger their release of oxytocin too, as can warm physical contact like touching and hugging. (Levels increase during sex and peak at orgasm, which may help explain the age-old question “But will you love me in the morning, when your oxytocin levels have dropped?”) Oxytocin reduces stress in arguing couples, helps us recognize faces, even helps us look at a face (in fact, just a pair of eyes) and identify the mood that person is in. The stuff is magic.
Although maternal bonding may not always be hardwired — after all, human females can adopt babies and take care of them — oxytocin released during pregnancy "does seem to have a role in motivation and feelings of connectedness to a baby," Young said. Studies also show that interacting with a baby causes the infant's own oxytocin levels to increase, he added. 
At least one study using an extract of Griffonia simplicifolia (10.24mg giving 2.56mg 5-HTP; confounded with Centella asiatica and Taraxacum officinale at 11.7mg and 4.55mg Paulina cupana and 9.75mg Artichoke extract) taken in three hits, five times a day (40mg 5-HTP total), by 20 overweight or obese females (non-depressive and without eating disorders) for 4 weeks has noted an increase in satiety and reduced binge eating tendencies; the increase in satiety was said to account for the improved weight loss results seen in the experimental group when both were given weight loss advice and diets.[3] This spray has been noted elsewhere to increase satiety (and vicariously through that, body weight) over 2 months in a similar demographic of women.[2]

To determine the direct effect of Tβ4 peptide on osteoclastogenesis, mouse BMMs were directly exposed to Tβ4 peptide. Direct treatment with Tβ4 peptide also reduced the number of multinucleated TRAP-positive cells and TRAP activity in a dose-dependent manner (Fig 7A and 7B). Since Tβ4 downregulated H2O2-induced various cytokines expression, the indirect effect of Tβ4 on osteoclast formation through PDLC cells using co-culture system were investigated. After addition of Tβ4 peptide to the BMMs-PDLCs co-culture, the number of osteoclast and TRAP activity were also significantly decreased (Fig 7C and 7D).


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!
Melanotan II is a synthetic analogue of the α-melanocyte stimulating hormone (α-MSH). α-MSH is a melanocortin I receptor agonist which has a role in human pigmentation by stimulating production of eumelanin. Melanotan II was originally developed as a treatment for sexual dysfunction. However, the proposal was abandoned when development of the metabolite bremelanotide was established.
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.

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.

Both sexes secrete oxytocin - what about its role in males? Males synthesize oxytocin in the same regions of the hypothalamus as in females, and also within the testes and perhaps other reproductive tissues. Pulses of oxytocin can be detected during ejaculation. Current evidence suggests that oxytocin is involved in facilitating sperm transport within the male reproductive system and perhaps also in the female, due to its presence in seminal fluid. It may also have effects on some aspects of male sexual behavior.

Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours and then incubated with 200 μM H2O2 for 48 hours (A-E). Cell viability was measured by MTT assay (A). Protein and mRNA expressions were assessed by RT-PCR (B) and Western blot analysis (C), respectively. The production of NO (D) and PGE2 (E) were measured by Griess reaction and ELISA, respectively. Data replicated the quantifications of cytotoxicity, NO, and PGE2 with the standard deviation of at least three experiments (n = 4). 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. # Statistically significant difference compared with the H2O2—treated group.


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.
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.
Research shows that co-administration with carbidopa greatly increases plasma 5-HTP levels.[46] However, several studies have reported that 5-HTP is effective even without a peripheral decarboxylase inhibitor (e.g. carbidopa).[47][unreliable medical source?] Other studies have indicated the risk of a scleroderma-like condition resulting from the combination of 5-HTP and carbidopa.[48]
