Oxytocin Purity: 291 Lab Tests Across 132 Identified Manufacturers
351 studies on Oxytocin curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.
Bottom line: TitrateLab currently tracks 291 published third-party lab tests of Oxytocin across 132 identified manufacturers. Among reports with a positive numeric purity result, the average is 98.07%. Within this published corpus, 8 positive purity results were below 90%, and 20 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 291 Oxytocin batches across 132 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, 54 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 Oxytocin
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 | 17 | 99.53% | 0 of 14 (0.0%) 0 0% / not detected · 0 wrong compound · 3 unclassified | Reveal with Pro → | |
