Retatrutide 40mg — High-Strength Triple Agonist Research Peptide

Retatrutide 40mg is a high-strength single-vial presentation for laboratory researchers studying multi-receptor metabolic pathways. Each vial contains 40mg of Retatrutide as a lyophilised powder, sealed and independently assayed to ≥99% purity.
