Selective MC1R agonist primary receptor target MC1R with secondary activity at MC3R, MC4R, MC5R Two targeted modifications vs native -MSH Nle and D-Phe enhance metabolic stability in experimental systems Linear 13 amino acid structure distinct from cyclic MT-2 (Melanotan II) with different receptor selectivity profile Activates cAMP/PKA signaling cascade via MC1R in cell-based research systems Studied extensively in melanogenesis, melanocortin receptor pharmacology, and comparative ligand selectivity research FDA-approved pharmaceutical equivalent (Scenesse/Afamelanotide) provides extensive published clinical literature for reference Lyophilized format ensures stability and reproducibility across experimental runs Batch and lot identifiers on all labeling for full laboratory documentation compliance Research Background MT-1 (Afamelanotide) was developed in the 1980s at the University of Arizona by Mac Hadley and Victor Hruby as part of a program investigating synthetic -MSH analogs for melanocortin receptor research

With those three inputs, it returns the volume to draw for any given dose

These effects often matter most when they interfere with fluids, nutrition, work, sleep, or diabetes management
