Melanotan-2 remains a research compound with significant safety concerns and no approved indications Introduction# Melanotan-1 and Melanotan-2 are both synthetic analogs of alpha-melanocyte-stimulating hormone (alpha-MSH) developed at the University of Arizona, yet they differ substantially in structure, receptor selectivity, therapeutic applications, and safety profiles
Some peptides are used in safety-tested, widely sold creams, serums, and moisturizers, which may help with skin texture
Notably, no randomized controlled trials (RCTs) prospectively designed and adequately powered to evaluate outcomes specifically in MC4R -deficient populations have been completed to date
