What the IGF-1 LR3 record shows

Evidence through 2026-08-18

TitrateLab tracks 130 published IGF-1 LR3 certificate-of-analysis records through 2026-08-18. Across 130 records with a usable peptide-purity result, the median reported purity is 99.1%. Across 85 records with measured-versus-label dose data, 38% 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.
