Kpv: 1,988 published COA source records

14 studies on Kpv curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.

Bottom line: TitrateLab indexes 1,988 published Kpv COA source records from third-party laboratories, covering 719 publicly attributable vendor identities. Across 1,755 records with positive numeric purity, the arithmetic mean is 99.56%. 0 records report zero purity; these remain in the record count and are excluded from the positive-purity mean. 1 positive purity results are below 90%; 75 records report measured amount more than 10% below the label. The latest recorded test date is 2026-10-16. TitrateLab did not perform these laboratory tests. Source records are not unique batches, and vendor identity does not establish manufacturing role, product safety or overall quality.

Kpv average prices

As of 2026-10-18, vendor-blind retail asking-price averages for the US delivery market, calculated from the same in-stock exact-strength cells as the Peptide Price Index. Shipping is excluded.

Kpv: published third-party laboratory evidence

All published source records, including absent and zero purity. Matching uses a case-insensitive exact peptide token. No deduplication in the headline; vendor rankings deduplicate eligible certificates separately. The COA archive can use normalized compound names and a different measurement or duplicate policy; totals from these populations need not match.

Latest recorded test: 2026-10-16. Aggregate calculated: 2026-10-18T19:57:04.956696+00:00. Calculation time is not a laboratory observation date.

Within that total, 683 source records have unresolved vendor identity. They remain in corpus-level lab evidence and are excluded from named-vendor rankings.

Top 3 vendor evidence profiles for Kpv

Eligible vendors have at least 2 deduplicated certificates and 2 classifiable identity observations. Rank uses the 95% lower confidence bound on clean identity results; mean positive purity and certificate count break ties. Missing measurements are not passes. Exact-zero/not-detected and explicit wrong-compound markers count once per adverse certificate. This describes submitted-sample evidence, not every product or shipment, and is not an endorsement.
