Operating structure. CD Biolab is a national research-peptide brand operated as a DBA (“doing business as”) of Peptides Express, a Fresno, California research-peptide company. In plain terms: Peptides Express is the lab and business behind CD Biolab — they source, test, and ship every order, while CD Biolab is the national storefront, brand, and customer experience built on top of it.
How our sourcing works
Every product you see on CD Biolab is sourced and fulfilled by Peptides Express in Fresno, California. Here's the chain, start to finish:
- Sourcing. Peptides Express 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 CD Biolab are fulfilled and shipped directly from the Peptides Express 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: Peptides Express runs the lab, the testing, and the fulfillment; CD Biolab 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.
