Overview Melanotan-2 is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH), a naturally occurring peptide that plays a central role in pigmentation, sexual function, and appetite regulation. It has been the subject of significant research interest for its ability to stimulate melanin production in the skin and its well-documented effects on libido and sexual arousal pathways.
Mechanism of Action Melanotan-2 binds to melanocortin receptors — primarily MC1R and MC4R. Activation of MC1R stimulates melanogenesis, the production of melanin in skin cells, resulting in increased pigmentation. Activation of MC4R in the central nervous system has been linked to sexual arousal, appetite suppression, and energy regulation. This dual-receptor activity makes Melanotan-2 one of the most multi-functional peptides in research.
Research Applications Research on Melanotan-2 has primarily focused on its role in skin pigmentation and photoprotection, sexual dysfunction (particularly in the context of erectile dysfunction and hypoactive sexual desire), and appetite and weight regulation. Studies have also explored its potential neuroprotective properties and its role in modulating inflammatory responses.
Reconstitution & Storage Melanotan-2 is supplied as a lyophilized powder. Reconstitute by adding bacteriostatic water slowly along the inner wall of the vial. Store unreconstituted vials in a cool, dry place away from direct light — Once reconstituted, keep refrigerated.
