Every vial tested. Every lot traceable.
Peptides are only as good as the lab that made them and the paperwork that proves it. Here's exactly what we test for, who tests it, and how to verify the lot in your hand.

Meridian Biosciences (US)
Every peptide on PepVault is sourced from Meridian Biosciences — a US-based wholesaler operating out of a cGMP-aligned compounding facility. Every lot is synthesized, tested, and quality-controlled in the same facility before shipping, and every shipment carries a lot-matched certificate of analysis.
Placeholder supplier shown for preview. Real supplier identity and documentation will be substituted before launch.
Every lot tested on high-performance liquid chromatography at Meridian Analytical Services. Minimum 98% purity threshold; vials below that are rejected at intake, not discounted.
Mass spectrometry confirms the actual peptide sequence — not just that something is in the vial, but that it's the molecule on the label.
Sterile vials carry USP <71> sterility and USP <85> endotoxin results. Non-sterile research material is labeled as such — no ambiguity.
Independent re-testing by Janoshik Analytical is performed on routine intervals and linked from each peptide's COA where available.
Look up the COA for the lot you received.
Every vial ships with a lot number printed on the label. Enter it below and the matching certificate of analysis — HPLC purity, mass-spec identity, sterility results — opens immediately.

PepVault is not a pharmacy. Most peptides on this site are sold for research use only and are not approved as drugs for human use by the FDA or equivalent agencies. Nothing here is medical advice. See the Safety page for the full picture.
PepVault does not hold a regulatory certification (cGMP, ISO, SOC 2). Our supplier's manufacturing facility operates under its own certifications, which we can share on request via trust@pepvault.bio.
