Retatrutide 16mg is the largest vial of this triple-agonist peptide offered by Peptide Sciences, providing the best value per milligram for extended research programmes and shared laboratory supply.
Retatrutide Structure and Receptor Balance
Retatrutide is built on a GIP-based peptide backbone with residue substitutions that create balanced activity at the glucagon and GLP-1 receptors, plus a fatty-diacid modification for extended half-life. Its receptor potency profile, strongest at GIP and somewhat lower at glucagon and GLP-1, is a subject of ongoing structure-activity research for designing multi-receptor peptides.
