One peptide. Fully documented.
Retatrutide, developed by Eli Lilly and Company under the code LY3437943, is a synthetic lipidated peptide studied as a triple receptor agonist. It is built on a 39 amino acid sequence carrying proprietary modifications, and is supplied as a white to off-white lyophilized powder that reconstitutes in sterile water or standard laboratory buffers.
It is an investigational compound: not approved by the FDA or other major regulators for clinical or human use. Published research reports a half-life of approximately 6 days. Every batch we distribute is sold strictly for laboratory research — not for human or animal consumption.
Because retatrutide is the only compound we carry, our sourcing, storage, and documentation are built around this one molecule rather than spread across a wide catalog.
