Melanotan I is an artificial peptide synthesized to mimic the structure of the human hormone alpha-melanocyte stimulating hormone (α-MSH). Administered via subcutaneous injection, it works by stimulating melanocytes in the skin to produce and distribute melanin, darkening skin tone for a tanned appearance. This process is believed to boost the skin’s natural UV defense and reduce sun-induced damage. As a non-specific melanocortin receptor agonist, Melanotan I influences various physiological processes, including skin pigmentation regulation and potential relief of light sensitivity symptoms.

The peptide will be provided as lyophilized powder to ensure maximum stability.
