Ghk-cu: 5,085 published COA source records

68 studies on Ghk-cu curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.

Bottom line: TitrateLab indexes 5,085 published Ghk-cu COA source records from third-party laboratories, covering 1,337 publicly attributable vendor identities. Across 4,551 records with positive numeric purity, the arithmetic mean is 99.66%. 12 records report zero purity; these remain in the record count and are excluded from the positive-purity mean. 13 positive purity results are below 90%; 440 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.

Ghk-cu 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.

Ghk-cu: 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: 2026-10-18T01:49:34.747069+00:00. Calculation time is not a laboratory observation date.

Within that total, 1309 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 Ghk-cu

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.
