Melanotan 2 Structural Name: Ac-cyclo[Nle4, Asp5, D-Phe7, Lys10]α-MSH4-10-NH2
Appearance : Freeze dry powder,White Powder
Storage: Closed, below 2 ~ 8?C preservation
Usage:Melanotan 2 has been shown in studies to exhibit appetite suppressant, lipolytic, and libido-enhancing effects in addition to promoting skin tanning. Melanotan 2 has been researched extensively for use in protecting against the harmful effects of ultraviolet radiation from sunlight due to its melanogenesis-stimulating properties.


The ability to achieve a darker tan with less exposure to UV radiation
Possible reduction in the risk of Melanoma (skin cancer)
A possible reduction in the incidence of sun-damaged skin
Fair skin individuals have the ability to develop a tan through the use of the MT2 peptide.
It can lead to reduction in body fat
No sunburn, No tan lines
No sunless tanning streaks or fake tan removal
It can increase libido
(During clinic trials for its use as a tanning agent, melanotan II was found to be a potent stimulator of male erections. It has also been shown to increase female sexual desire in patients with sexual arousal disorder).


MT-2 (or Melanotan II) is another synthetic peptide of hormones nature and lactam cyclic analog of melanocortin protein hormone alpha-melanocyte stimulating hormone; Its molecular weight/mass is 1024.2 with molecular formula is C50H69N15O9. This analog has typical features of proteins. Melanotan II was purposely created in 1991 by American researchers from Arizona under leadership of Hruby/Hedley, while they were looking for more stable and potent modification of primal MSH. After that numerous clinical studies took part in different countries to identify efficacy of newly developed peptide.
Like its predecessor, Melanotan I, MT-2 plays role in stimulating melanogenesis and by that providing protective mechanism against UV rays since under its actions melanocytes are able to increase production and secretion of hormone melanin which is also kind of peptides. However, scientists were also able to notice another characteristic of this research compound which is certain aphrodisiac effects. It also has mild positive fat-mobilizing effect.
