IGF-1 Certificate of Analysis Results
What the IGF-1 record shows
Evidence through 2026-03-07TitrateLab tracks 11 published IGF-1 certificate-of-analysis records through 2026-03-07. Across 11 records with a usable peptide-purity result, the median reported purity is 99.4%. Across 8 records with measured-versus-label dose data, 62% 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.
- Coverage depends on reports that were published and available to ingest.
