Description – Melanotan II

Melanotan II is a synthetic variant of the naturally occurring peptide hormone alpha-melanocyte stimulating hormone (α-MSH)1, which acts to stimulate the production of melanin in the skin – the molecule responsible for hair and skin pigmentation – through a process called melanogenesis2. Naturally occurring α-MSH has also been shown to play a role in feeding, the maintenance of useable and stored energy, and sexual activity through its action as an agonist of melanocortin receptors MC1, MC3, and MC4; MC1 being responsible for skin pigmentation effects, and MC3 and MC4 being responsible for effects on appetite, metabolism, and sexual activity3.Melanotan II is a cyclic heptapeptide originally developed as a defense against the potential cancer-causing effects of the sun’s ultraviolet radiation through its action of stimulating natural melanin production in the absence of sunlight4, which allows for the sunless darkening of skin tone.In addition to its promotion of skin tanning, Melanotan II has been shown to be a lipolytic (fat cell-destroying) agent5, a suppressant of appetite6, and a stimulant of libido in animal test subjects7. Melanotan II has demonstrated great efficacy in reducing caloric intake, while eliminating cholesterol and fat stores in obese mice through its targeted metabolic action8.

Product Comparison – Melanotan II

Melanotan II and Melatonan I, both synthetic analogues of α-MSH, produce similar effects in terms of skin tanning by binding the MC1 receptor9, though Melanotan II is unique in this family of agents in that it stimulates an aphrodisiac effect (MC3 and MC4), improving libido significantly in test subjects.

PT-141 is structurally similar to the biosynthetic peptide hormone Melanotan II, but has shown to be a potent binding agent of MC3 and MC4 only, showing no affinity for MC1. In animal tests, PT-141 has proven quite effective at correcting sexual dysfunction7, while Melanotan II induces an additional effect on skin tone.

Unlike other agents that have an effect on erectile response, Melanotan II performs no action on the vascular system, but rather induces arousal and heightens sexual desire via the nervous system – binding important receptors in the brain10.
