GHRP-2: 126 published COA source records
67 studies on GHRP-2 curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.
Bottom line: TitrateLab indexes 126 published GHRP-2 COA source records from third-party laboratories, covering 56 publicly attributable vendor identities. Across 113 records with positive numeric purity, the arithmetic mean is 99.31%. 0 records report zero purity; these remain in the record count and are excluded from the positive-purity mean. 0 positive purity results are below 90%; 9 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.
GHRP-2 average prices
As of 2026-10-19, 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 |
|---|---|---|---|---|
| 5 mg | $4.75 | $4.00–$5.50 | $0.95 | 2 sources · 2 offers |
| 10 mg | $7.00 | $6.50–$7.50 | $0.70 | 2 sources · 2 offers |

GHRP-2: 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: 2026-10-19T23:05:32.991742+00:00. Calculation time is not a laboratory observation date.
Within that total, 29 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 GHRP-2
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 | 9 | 99.18% | 0 of 9 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → | |
| #2 | 7 | 99.44% | 0 of 7 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → | |
| #3 | 4 | 99.51% | 0 of 4 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → |
Vendor identities are included with Pro. Record counts and lab measurements remain visible.
