Melanotan I
MT-1, also known as Melanotan I, is a synthetic peptide belonging to the melanocortin receptor agonist class. It is structurally derived from alpha-melanocyte-stimulating hormone and is designed to interact primarily with melanocortin receptors, particularly MC1 pathways. It is studied for its role in modulating pigmentation and melanocortin signaling processes. Commonly utilized in research settings to investigate peptide-mediated signaling mechanisms related to melanocortin receptor activity. Supplied by Peptico for research-use only.
