Semaglutide Certificate of Analysis Results
What the Semaglutide record shows
Evidence through 2026-08-18TitrateLab tracks 1,087 published Semaglutide certificate-of-analysis records through 2026-08-18. Across 1,087 records with a usable peptide-purity result, the median reported purity is 99.7%. Across 832 records with measured-versus-label dose data, 49% 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.
Limits and missing evidence
- The testing laboratory is unattributed on 8 records.
- Coverage depends on reports that were published and available to ingest.
