In short: Retatrutide is a synthetic single-peptide triple receptor agonist studied as an investigational compound for GLP-1, GIP and glucagon receptor signalling. It is supplied strictly for laboratory research and is not approved for human use. For research buyers, the key purchasing criteria are verified purity (≥99% HPLC), confirmed identity (mass spectrometry) and batch traceability.
What is Retatrutide?
Retatrutide (also referenced as LY3437943) is a 39-amino-acid synthetic peptide engineered to act on three receptors simultaneously: glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP) and glucagon. As a research compound it is studied for metabolic-pathway signalling. It is an investigational compound and is not an approved medicine — it is not approved for therapeutic or human use.
What does the research investigate?
Retatrutide has been the subject of published clinical-trial literature investigating triple-receptor agonism in metabolic models, including phase-2 studies of body-weight and glycaemic endpoints and liver-fat reduction. Because this is an actively investigated, unapproved compound, the published data are evolving. Important: clinical research conducted under regulated trial conditions does not authorise use of research-grade material outside the laboratory. Always read the primary sources directly.
Purity and quality: what research buyers should check
For reproducible research, compound quality is everything:
- ≥99% purity by HPLC — confirm via the batch Certificate of Analysis.
- Identity by mass spectrometry — confirms the correct molecular weight.
- Batch numbering — traceability to a tested lot.
Vexar Lab supplies Retatrutide as a pack of 10 vials, ≥99% HPLC-verified, batch-numbered, with mass-spec confirmation.
Handling and storage
Follow standard lyophilised-peptide practice: store sealed vials appropriately, reconstitute with the diluent specified by your method, and record batch numbers in your lab notes.
Wholesale supply
Retatrutide is available wholesale: packs of 10 vials, £300 minimum order, bulk pricing on volume, £45 flat worldwide shipping, and optional custom labelling for resellers.
Frequently asked questions
Is Retatrutide an approved drug?
No. It is an investigational compound supplied for in-vitro laboratory research only and is not approved for human consumption.
What makes it a “triple agonist”?
It is engineered to bind and activate three receptors — GLP-1, GIP and glucagon — within a single peptide.
