Vendor-supplied · Not verified by PeptideBase
What this vendor publishes about itself, repeated here. Disclosure is not verification; only independent lab results change that.
5 certificates on file, all self-published by the vendor. Median purity 99.51%, against 99.68% across all 928 certificates we score. One of four compounds test at or above their market median. The exception is a BPC-157 lot at 99.40% — 0.32 points below the 99.72% median for that compound.
Evidence provenance
- 5 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
4 of 4 results sit within ±0.4 points of their market median.
1 further result is not plotted — no purity figure, or too few market results for that compound to compare against. They appear in the table below.
