CJC-1295 Certificate of Analysis Results
What the CJC-1295 record shows
Evidence through 2026-08-30TitrateLab tracks 892 published CJC-1295 certificate-of-analysis records through 2026-08-30. Across 891 records with a usable peptide-purity result, the median reported purity is 99.6%. Across 735 records with measured-versus-label dose data, 48% 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 1 record.
- Coverage depends on reports that were published and available to ingest.
