Vendor-supplied · Not verified by PeptideBase
What this vendor publishes about itself, repeated here. Disclosure is not verification; only independent lab results change that.
39 certificates on file, all self-published by the vendor. Median purity 99.76%, against 99.68% across all 928 certificates we score. 21 of 24 compounds test at or above their market median. The exception is a MOTS-c lot at 98.32% — 1.09 points below the 99.41% median for that compound, and the only result here outside the corpus's middle 80%.
Where this evidence comes from
Evidence provenance
- 39 self-published
- COAs the vendor posted on their own site.
Recorded for completeness. A self-published document doesn't count as confirmed on its own — the document is real, the chain of custody isn't independent.
Purity vs market
Every certificate, placed against the median for its own compound across all 928 results we score.
28 of 36 results sit within ±0.4 points of their market median.
