- People seeking independent analysis of research-peptide samples
- Worth noticing
- Its sample certificate labels client-supplied product details as unverified, while listing methods, limits, measured results, named reviewers, and a stored SHA-256 fingerprint.
Field notes
The example certificate marks product name, lot, and declared amount as client-provided rather than lab-verified. Separate result rows show methods and limits alongside measurements, and the page describes a live status check for issued certificates. Listed services include blind identification using a library of more than 140 research peptides; the site also reports accepting samples from 75 countries.
