Lilpeptide started in 2021 from a simple frustration: the research peptide market had no accountability, no documentation, and no one who would answer the phone. We built the company we wished existed.
Every compound in our catalog has a real CAS number, a real synthesis origin, and a real independent test result. If a batch doesn't hit ≥99% purity, we destroy it — we don't discount it.
We partner with two ISO 17025-accredited labs and publish every COA before a single vial ships. The lot number on your vial will always match an entry in our COA library.
≥99% HPLC on every lot, or we don't ship.
Published before shipment, matched by lot number.
