Compare lab measurements, vendor test histories and original reports for Ac-sdkp.
What the Ac-sdkp record shows
Evidence through 2026-08-04
TitrateLab tracks 17 published Ac-sdkp certificate-of-analysis source records through 2026-08-04, each with a recorded purity or measured-versus-label amount result. Across 16 records with a numeric peptide-purity result, including zero, the median reported purity is 99.8%. Across 15 records with measured-versus-label dose data, 27% 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.
Published records with a non-null purity or measured-versus-label amount result. Matching uses a normalized compound slug. No deduplication in this archive summary; relays and corrected records can remain separate. Records with neither measurement are excluded here, but can appear in the research overview's exact-token raw-record total. These are not unique certificates or batches. TitrateLab indexes reports from third-party laboratories.
