Retatrutide (20 mg) is a research-grade triple agonist engineered to engage GLP-1, GIP, and glucagon receptor pathways within a single molecule. This unimolecular design supports investigations into combinatorial receptor activity, offering researchers a tool for studying metabolic signaling mechanisms that extend beyond conventional single- or dual-agonist models. Each lot of Retatrutide is manufactured under strict quality protocols and verified through third-party testing, with a Certificate of Analysis (COA) available for every batch to confirm purity and identity. Supplied at 20 mg for laboratory research applications exploring energy expenditure and body weight regulation pathways, this product is intended strictly for in vitro or preclinical research use—not for human or veterinary consumption.
Yes. Every lot of Retatrutide (CAS 2381089-83-2) is tested for identity and purity to ≥99% by HPLC, and a lot-matched Certificate of Analysis is available for each batch.
Yes. The lot-matched COA is linked on this page and covers identity, purity, and the full analytical panel. If a COA isn't shown for the strength you need, AA LABS can send it on request before you order.
