What the GHRP-6 record shows

Evidence through 2026-08-26

TitrateLab tracks 128 published GHRP-6 certificate-of-analysis records through 2026-08-26. Across 128 records with a usable peptide-purity result, the median reported purity is 99.6%. Across 97 records with measured-versus-label dose data, 45% 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.
