Operating structure. Fresno Athletic Lab is a national research-peptide brand operated as a DBA (“doing business as”) of Express Peptides, a Fresno, California research-peptide company. In plain terms: Express Peptides is the lab and business behind Fresno Athletic Lab — they source, test, and ship every order, while Fresno Athletic Lab is the national storefront, brand, and customer experience built on top of it.
How our sourcing works
Every product you see on Fresno Athletic Lab is sourced and fulfilled by Express Peptides in Fresno, California. Here's the chain, start to finish:
- Sourcing. Express Peptides procures research-grade material and lyophilizes and seals each vial to a 99%+ purity standard.
- Testing. Every batch is independently third-party tested — HPLC for purity and mass spectrometry for identity — and issued a Certificate of Analysis (COA).
- Fulfillment. Orders placed through Fresno Athletic Lab are fulfilled and shipped directly from the Express Peptides lab in Fresno, typically within 1–3 business days, with the matching batch COA.
- Support. Because it's a real local lab, you can reach a real person by phone or text before or after you order — (559) 939-5274.
Why we built it this way
Splitting the roles keeps each side doing what it does best: Express Peptides runs the lab, the testing, and the fulfillment; Fresno Athletic Lab runs the national brand, the research content, and the customer experience. The result for you is a storefront that's easy to buy from, backed by a real US lab with real COAs — not an anonymous drop-shipper.
