1 study on Ostarine curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.
Bottom line: TitrateLab indexes 16 published Ostarine COA source records from third-party laboratories, covering 11 publicly attributable vendor identities. Across 2 records with positive numeric purity, the arithmetic mean is 98%. 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%; 0 records report measured amount more than 10% below the label. The latest recorded test date is 2026-01-28. 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.
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: 2026-01-28. Aggregate calculated: 2026-09-26T09:24:14.548699+00:00. Calculation time is not a laboratory observation date.
Within that total, 4 source records have unresolved vendor identity. They remain in corpus-level lab evidence and are excluded from named-vendor rankings.
