What the Tesamorelin record shows

Evidence through 2026-09-02

TitrateLab tracks 3,681 published Tesamorelin certificate-of-analysis records through 2026-09-02. Across 3,679 records with a usable peptide-purity result, the median reported purity is 99.6%. Across 3,248 records with measured-versus-label dose data, 46% 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.
