Retatrutide is an investigational triple receptor agonist targeting GLP-1, GIP and glucagon receptors, supplied by MyPeptides for laboratory research use only.
Retatrutide is an investigational triple receptor agonist targeting GLP-1, GIP and glucagon receptors. MyPeptides supplies it as a lyophilised 5 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
Researchers reach for Retatrutide in metabolic, body-composition and incretin-signalling research. It is offered strictly for laboratory investigation — no personal-use claims, no dosing guidance, and no framing as a medicine.
The point of buying research grade rather than generic material is documentation. Every Retatrutide order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. One of the few triple agonists available at research grade — HPLC assayed with a signed CoA per batch.

Clean product, no discoloration, correct fill. Certificate of analysis was in the box AND emailed. Very straightforward experience.
The little details matter - proper cold-chain, tamper-evident seals, and a CoA that actually reads like a lab report and not a marketing sheet.
Ordered late Monday, arrived Wednesday morning in the UK. Packaging was cold-protected and every vial sealed correctly. CoA matched the batch number on the label.
Been using peptides for research for years and MyPeptides is now my go-to. Consistent quality, quick turnaround, real documentation.
Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.
