What the GLP3 record shows

Evidence through 2026-05-06

TitrateLab tracks 8 published GLP3 certificate-of-analysis records through 2026-05-06. Across 8 records with a usable peptide-purity result, the median reported purity is 99.8%. Across 4 records with measured-versus-label dose data, 50% are within 10% of the labeled quantity. This is a public convenience sample, not a randomized market survey; one result describes one submitted sample and does not verify other batches.
