MELANOTAN II PEPTIDE 10MG LIQUID SPRAY 15ML BOTTLE (100MCG/SPRAY, 10MG TOTAL)

Melanotan II is a highly potent, synthetically engineered, truncated analog of the endogenous peptide hormone $\alpha$-melanocyte-stimulating hormone ($\alpha$-MSH). Delivered via a mucosal liquid spray for rapid systemic absorption, its primary mechanism of action involves aggressively and non-selectively agonizing melanocortin receptors (specifically MC1R, MC3R, and MC4R). By strongly activating the MC1R pathway, it deeply stimulates melanogenesis (the production of melanin) within the skin, providing profound photoprotection against UV radiation. Secondary agonism at the MC3R and MC4R receptors frequently induces powerful systemic effects, including appetite suppression and significantly enhanced libido.
