Melanotan 1 (MT1 / afamelanotide) is a melanocortin-receptor research peptide used in controlled in-vitro studies of receptor pharmacology, second-messenger signalling, and structure–activity relationships under non-clinical laboratory conditions.
Melanotan 1 (MT1 / Afamelanotide) — 10 mg | Research Use Only
This α-MSH analogue incorporates Nle4 and D-Phe7 substitutions (NDP-α-MSH), making it a useful tool for exploring melanocortin receptor engagement and downstream pathways in model systems.
For laboratory research only. Not for human use.
