Retatrutide is a triple GIP/GLP-1/glucagon receptor agonist (MW ~4,731 Da) — the newest and most structurally complex of the incretin research peptides. Its novelty and demand make verified synthesis quality essential.
What to Look for When Sourcing Retatrutide
Require a third-party COA (HPLC and mass spectrometry) confirming ≥98% purity and the ~4,731 Da molecular weight per batch. As a triple agonist, it is the most complex to synthesize correctly, so identity verification is critical.
Typical Price Range
Research-grade retatrutide typically costs about $50–$80 per vial. As the newest incretin compound, pricing is higher and more variable than for semaglutide or tirzepatide.
Storage and Handling
Store lyophilized retatrutide at 2–8°C, or frozen for long-term storage. Once reconstituted, refrigerate and use within the vendor's stated window.
Red Flags to Avoid
Missing or generic COAs, MW mismatch, prices far below market for a novel compound, and human-use or clinical-equivalence claims.
