We tested 544 Kisspeptin batches across 292 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, 115 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 Kisspeptin
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 | 11 | 99.74% | 0 of 11 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → | |
| #2 | 15 | 99.53% | 0 of 11 (0.0%) 0 0% / not detected · 0 wrong compound · 4 unclassified | Reveal with Pro → | |
| #3 | 7 | 99.64% | 0 of 7 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → |
Manufacturer identities are included with Pro. Batch counts and lab measurements remain visible.
