What it is
Melanotan II activates MC1R receptors in melanocytes to produce a tan. It is the most-discussed tanning peptide, though it carries notable side effects (nausea, flushing, dark spots, mole changes) that demand caution. Dermatologist supervision is sensible.
Mechanism
Non-selective melanocortin receptor agonist. Stimulates melanin production (MC1R) and central arousal pathways (MC4R).
