What the GLP-1 record shows

Evidence through 2026-04-01

TitrateLab tracks 8 published GLP-1 certificate-of-analysis records through 2026-04-01. Across 8 records with a usable peptide-purity result, the median reported purity is 99.7%. Across 4 records with measured-versus-label dose data, 25% 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.
