What the Semax record shows

Evidence through 2026-09-01

TitrateLab tracks 1,278 published Semax certificate-of-analysis records through 2026-09-01. Across 1,277 records with a usable peptide-purity result, the median reported purity is 99.5%. Across 1,092 records with measured-versus-label dose data, 31% 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.
