Compounds go to an independent US lab before they reach the catalog, purity by reverse-phase HPLC and identity by mass spectrometry. Where a lot has been tested, its Certificate of Analysis is published on the product page, so you can read the actual result before you order.
Reverse-phase HPLC
Purity quantified against reference standards. It is the headline number on the certificate.
Mass spectrometry
Molecular identity confirmed. The compound is exactly what the label claims.
Lot-matched COA
A published certificate is tied to one lot ID, not a generic sample. Compare it to the lot on the vial you receive.
Independent third-party lab
Assayed by Horizon Analytical, a US-based laboratory. We don't grade our own work.
99%+ documented purity
The bar a lot has to clear. The measured figure is printed on the certificate, not rounded up in marketing.
Zero fillers
Pure active compound, lyophilized. No binders, no excipients, no filler content.
Synthesized & lyophilized
Produced to a defined specification and freeze-dried to a room-temperature-stable powder, no cold chain required.
Independently assayed
Samples are sent to Horizon Analytical for HPLC purity and mass-spec identity confirmation.
Certificate published
The COA is archived against the lot ID and posted on the product page for you to check. Certificates live on the site, they are not shipped in the box.
Sealed & shipped
Vials are sealed and shipped discreetly within the US, dispatched in about 48 hours.
Anyone can publish a PDF. Independent verification is what separates real transparency from marketing. Genetic Peptides USA is currently the #1-ranked US vendor on PepAssure, an independent platform with zero paid placements that cross-checks lab reports and spot-tests vendors through anonymous purchases.
Verify us on PepAssureA certificate is only useful if it's specific. Every certificate we publish ties a result to a lot ID you can check, and it sits on the product page before you spend anything. Not every compound in the catalog carries one yet, so open the library and check the one you want before you order.
