GLP-1: 21 published COA source records
1 study on GLP-1 curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.
Bottom line: TitrateLab indexes 21 published GLP-1 COA source records from third-party laboratories, covering 8 publicly attributable vendor identities. Across 13 records with positive numeric purity, the arithmetic mean is 99.77%. 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 2026-04-01. 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.
GLP-1: 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: 2026-04-01. Aggregate calculated: 2026-09-14T00:14:15.120449+00:00. Calculation time is not a laboratory observation date.
Within that total, 8 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 GLP-1
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 | 3 | 99.83% | 0 of 3 (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.
