Selank Certificate of Analysis Results
What the Selank record shows
Evidence through 2026-09-01TitrateLab tracks 1,179 published Selank certificate-of-analysis records through 2026-09-01. Across 1,179 records with a usable peptide-purity result, the median reported purity is 99.8%. Across 1,017 records with measured-versus-label dose data, 37% 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 4 records.
- Coverage depends on reports that were published and available to ingest.
