Melanotan 1 , also designated Afamelanotide and is a synthetic tridecapeptide melanocortin receptor agonist and one of the most extensively characterised MC1R-selective research compounds available to laboratories in Ireland , a metabolically stabilised linear analogue of alpha-melanocyte-stimulating hormone (-MSH) incorporating Nle4 and D-Phe7 substitutions that confer proteolytic resistance and enhanced MC1R binding affinity while preserving the natural -MSH peptide backbone, producing potent and sustained melanogenesis, photoprotection, and anti-inflammatory effects through MC1R activation in melanocytes, keratinocytes, and immune cells, making it an indispensable research tool for studying MC1R receptor pharmacology and downstream melanogenesis signal transduction, ultraviolet radiation-independent melanin synthesis and skin pigmentation biology, MC1R-mediated photoprotection and DNA damage prevention mechanisms, the anti-inflammatory biology of melanocortin receptor activation in skin and systemic immune contexts, erythropoietic protoporphyria biology and photoprotection research, MC1R genetics and the relationship between receptor polymorphisms and pigmentation phenotype, and the comparative pharmacology of melanocortin receptor agonists across the MC1R through MC5R receptor family, Researchers and institutions across Ireland can source verified, research-grade Melanotan 1 directly from our Irish peptide supply, with domestic-speed dispatch and complete batch documentation
