Research peptides
built on proof.
Every lot is tested by USA Prime Labs, our affiliated laboratory, for HPLC purity and endotoxin, and its Certificate of Analysis is published before the lot is listed. Each product page lists the compound's sequence, CAS number, molecular formula and weight, and the lot's certificate.
Paperwork, not promises.
Anyone can claim purity. We publish the evidence — 243 real lot certificates, viewable by anyone, before a single order is placed. Those documents on the left are the actual scans.
- HPLC / LC-MS purity analysis on every production lot
- USP <85> bacterial endotoxin (LAL) screening, run in duplicate
- Certificates matched to lot numbers you can verify with the testing lab
- Heavy-metals panels published where applicable

We run our own warehouse inventory, our own procurement, and our own vendor relationships — which is why we can show you a live stock status and a lot-matched certificate instead of a stock photo and a promise.
Inventory held and shipped domestically, with a real returns address and real people answering.
What you see in the catalog is our warehouse ledger — not a dropship feed.
