We exist because the research peptide market has a credibility problem. Untested products, fabricated certifications, and inconsistent quality have made it impossible for serious researchers to trust what's in the vial. We built US Certified Peptides to fix that, with one product line, one standard, and seven independent tests on every lot.
For decades, researchers ordering peptides have had to trust suppliers at their word. That was the problem we set out to solve.
Many suppliers create their own Certificates of Analysis in-house, or contract a one-time purity test and reuse the document for every subsequent batch. The COA you see may have nothing to do with the vial in your hand.
Without independent batch-by-batch verification, peptide quality drifts between lots. The same product from the same supplier can vary significantly in purity, identity, and contamination from one shipment to the next.
If something goes wrong, there's rarely a paper trail. Without third-party hosted certification, you have no independent record of what was actually tested, by whom, when, or against what standard.
These problems are not new. They have been the cost of doing peptide research for years.
"We decided to build something different."
Every lot is tested at an independent ISO/IEC 17025:2017 accredited laboratory before it ships. Each lot receives a lot-specific Certificate of Analysis hosted by the laboratory, with QR code verification on every vial.

US Certified Peptides serves a specific audience. We do not sell to end-users. We do not make therapeutic claims. We exist to support the work of qualified researchers, scientists, and laboratory professionals.
University-affiliated research teams studying peptide pharmacology, biochemistry, and translational science. Standard ordering, institutional billing, and grant-compliant documentation.
Private and contract research organizations conducting peptide screening, characterization studies, and preclinical analytical work.
Development teams sourcing research-grade peptides for early-stage discovery work, reference standard comparisons, and analytical validation programs.
Independent investigators with verifiable institutional affiliations, research credentials, or professional standing in life sciences research.
All accounts are reviewed for research eligibility before first purchase. We may request institutional affiliation, research credentials, or professional documentation. This is part of our commitment to keeping research peptides in qualified research hands.
All products sold by US Certified Peptides are intended strictly for laboratory research use only. They are not intended for human consumption, diagnostic application, or therapeutic use. Sales are limited to qualified research professionals.
From synthesis to testing to shipping, our operation is built on American regulatory frameworks, American accredited laboratories, and American supply chains.
Every analytical method we use traces back to a US regulatory framework. FDA Guidance for Industry. USDA APHIS protocols. United States Pharmacopeia general chapters. EPA validated methods. These are the standards that define rigor in American laboratory science.
Our independent testing partner operates an ISO/IEC 17025:2017 accredited laboratory in Olympia, Washington. Our certification, packaging, and shipping operations are US-based. Every step of the supply chain is documented, accountable, and answerable to American regulatory oversight.
This is not a marketing claim. It is an operational decision rooted in the belief that the highest standards in research chemistry belong here.
Made for research. Built in America. Verified by independent science.
