Melanotan 2 / MT-2

Melanocortin Agonist · Tanning + Libido + Appetite

Melanotan 2 Acetate is a synthetic injectable peptide designed to mimic the action of the body's endogenous melanocortins. It is widely recognized in biohacking for its disruptive dual effect: it is the most potent cutaneous tanning stimulator known to science and a drastic accelerator of sexual desire.

• Photoprotective sunless tanning (accelerated melanogenesis) — binding to MC1R stimulates melanocytes to produce eumelanin (the dark skin pigment), generating a deep, uniform tan with minimal or no sun exposure while shielding skin cells from UV damage and lowering melanoma risk in burn-prone phototypes
• Drastic libido stimulation (aphrodisiac effect) — activating central MC4R receptors and triggering dopamine release significantly increases sexual desire and intimate appetite; in men, generates spontaneous, firm, long-lasting erections
• Appetite suppression and fat loss — acts on hypothalamic satiety pathways to control food cravings while subtly accelerating metabolic rate (lipolysis)
• Dual central + peripheral action — unique among aesthetic peptides for simultaneously addressing skin pigmentation and CNS-driven desire
• Sustained pigment retention — established tan persists with maintenance dosing far below initial loading frequency
