Ahk-cu: 186 published COA source records
2 studies on Ahk-cu curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.
Bottom line: TitrateLab indexes 186 published Ahk-cu COA source records from third-party laboratories, covering 98 publicly attributable vendor identities. Across 171 records with positive numeric purity, the arithmetic mean is 99.15%. 0 records report zero purity; these remain in the record count and are excluded from the positive-purity mean. 2 positive purity results are below 90%; 8 records report measured amount more than 10% below the label. The latest recorded test date is 2026-10-14. 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.
Ahk-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.
| Strength | Average / vial | Observed range / vial | Average / mg | Coverage |
|---|---|---|---|---|
| 50 mg | $7.50 | $7.50–$7.50 | $0.15 | 1 source · 1 offer |
| 100 mg | $9.50 | $9.50–$9.50 | $0.10 | 1 source · 1 offer |
Asking prices are not manufacturing cost and do not establish product equivalence, quality, safety, or legality. View full price methodology →
Ahk-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: 2026-10-14. Aggregate calculated: 2026-10-18T06:20:48.612863+00:00. Calculation time is not a laboratory observation date.
Within that total, 62 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 Ahk-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.
| Rank | Vendor | Deduplicated certificates | Avg positive purity | Identity adverse results | |
|---|---|---|---|---|---|
| #1 | 5 | 99.73% | 0 of 5 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → | |
| #2 | 3 | 99.58% | 0 of 3 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → | |
| #3 | 4 | 99.3% | 0 of 3 (0.0%) 0 0% / not detected · 0 wrong compound · 1 unclassified | Reveal with Pro → |
Vendor identities are included with Pro. Record counts and lab measurements remain visible.
