99% purity is essential for all melanocortin receptor pharmacology studies, comparative SAR research, pro-sexual behaviour paradigms, and melanogenesis biology , where impurities including the linear uncyclised peptide, partially oxidised species, or C-terminal amide hydrolysis product (PT-141) would show altered receptor subtype selectivity and confound mechanistic attribution
While traditional GLP-1 agonists activate only GLP-1 receptors, tirzepatide also stimulates GIP receptors
