A US research-peptide supplier built on one idea: prove it.
Fresno Athletic Lab supplies research-grade peptides to laboratories, clinics, and qualified researchers across the United States. We started Fresno Athletic Lab because the market is full of unverified powder and vague claims — so we built the opposite: every batch third-party tested, every vial backed by a Certificate of Analysis you can read before you buy.
We're based in Fresno, California, which means national researchers get fast domestic shipping and local researchers get something rare in this industry: a real person to call.
Every compound we sell is analyzed by independent third-party laboratories using High-Performance Liquid Chromatography (HPLC) to confirm purity and mass spectrometry to confirm identity. We publish or provide the resulting Certificate of Analysis with every order so you always know exactly what you received and from which batch.
All products are sold strictly for research use only — not for human consumption. We don't provide dosing or administration guidance, and we hold our affiliate partners to the same standard. It's the only way to build something that lasts. Read our full research-use-only policy.
