Retatrutide + Tirzepatide Certificate of Analysis Results
What the Retatrutide + Tirzepatide record shows
Evidence through 2026-05-25TitrateLab tracks 4 published Retatrutide + Tirzepatide certificate-of-analysis records through 2026-05-25. Across 4 records with a usable peptide-purity result, the median reported purity is 100%. Across 2 records with measured-versus-label dose data, 50% 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
- No classifiable endotoxin results were recorded.
- The testing laboratory is unattributed on 1 record.
- Coverage depends on reports that were published and available to ingest.
