CJC-1295 Purity: 966 Lab Tests Across 373 Identified Manufacturers
25 studies on CJC-1295 curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.
Bottom line: TitrateLab currently tracks 966 published third-party lab tests of CJC-1295 across 373 identified manufacturers. Among reports with a positive numeric purity result, the average is 97.77%. Within this published corpus, 53 positive purity results were below 90%, and 128 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.
We tested 966 CJC-1295 batches across 373 identified manufacturers
Independent certificate-of-analysis evidence from third-party labs — the data behind the studies. Updated as new COAs are verified. Read the full grey-market analysis →
Within that total, 133 batches have unresolved manufacturer identity. They remain in corpus-level lab evidence and are excluded from named-manufacturer rankings.
Top 3 vendor evidence profiles for CJC-1295
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.
| Rank | Manufacturer | Tests | Avg positive purity | Identity adverse results | |
|---|---|---|---|---|---|
| #1 | 18 | 99.01% | 0 of 18 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → | |
| #2 | 13 | 99.64% | 0 of 13 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → | |
| #3 | 13 | 96.84% | 0 of 12 (0.0%) 0 0% / not detected · 0 wrong compound · 1 unclassified | Reveal with Pro → |
Manufacturer identities are included with Pro. Batch counts and lab measurements remain visible.
Recent certificates: #100399 (99.5%) · #100419 (99.58%) · #100815 (99.87%) · #101383 (99.35%) · #99547 (99.74%) · #99308 (99.71%)
