GHRP-6 Purity: 139 Lab Tests Across 71 Identified Manufacturers

107 studies on GHRP-6 curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.

Bottom line: TitrateLab currently tracks 139 published third-party lab tests of GHRP-6 across 71 identified manufacturers. Among reports with a positive numeric purity result, the average is 99.5%. Within this published corpus, 0 positive purity results were below 90%, and 11 reports showed measured quantity more than 10% below the label claim. These are batch-level observations, not guarantees of product identity, safety, or vendor quality.

Top 3 vendor evidence profiles for GHRP-6

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