Peptiva Labs was founded to fill the vacuum left by shuttered vendors — and to hold research-grade peptide supply to a standard the industry had abandoned.
Every compound in our catalog is HPLC-tested by an independent third-party laboratory before it ships. We don't rely on supplier COAs — we generate our own. Purity data is published publicly for every SKU, every lot.
Certificates of Analysis are not marketing collateral — they're the product. Lot numbers, test dates, purity percentages, and the identity of the testing lab are all published on every product page, always current.
Our compounds are sold exclusively for in-vitro and laboratory research use. We maintain strict research-only positioning across all operations, documentation, and customer communications — no exceptions, no ambiguity.
Peptiva Labs LLC is incorporated and operated in the United States. Fulfillment, customer support, and quality review all happen domestically. No grey-market sourcing, no offshore drop-shipping, no intermediaries.
Over the past several years, a wave of enforcement actions and supply-chain failures shuttered dozens of established peptide research vendors. The researchers who depended on them were left to choose between unknown grey-market suppliers with no testing documentation or abandoning their work entirely.
Peptiva Labs was founded specifically to fill that gap — not by rushing product to market, but by building the supply chain, the testing pipeline, and the documentation infrastructure first. We believe COA-first is the only way to operate in this space.
Every product we stock went through our quality pipeline before we listed it. That means independent HPLC verification, lot-level traceability, and public COA publication — not as an afterthought, but as the gate. If it doesn't clear the bar, it doesn't ship.
All products are sold strictly for laboratory and in-vitro research purposes by qualified researchers. We make no claims regarding therapeutic, diagnostic, or preventive applications of any compound in our catalog.
