What the GLP2 T record shows

Evidence through 2026-07-11

TitrateLab tracks 18 published GLP2 T certificate-of-analysis records through 2026-07-11. Across 18 records with a usable peptide-purity result, the median reported purity is 99.8%. Across 17 records with measured-versus-label dose data, 71% 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.
