Research use only. This vendor supplies peptides for laboratory and research purposes — not for human consumption or therapeutic use. PeptideBase does not endorse or guarantee product quality. Verify third-party lab testing before any research use.
29 certificates on file, all self-published by the vendor. Median purity 99.76%, against 99.68% across all 614 certificates we hold. Seventeen of 22 compounds test at or above their market median. The exception is a PT-141 lot at 99.79% — 0.10 points below the 99.89% median for that compound.
Evidence provenance
- 29 self-published
- COAs the vendor posted on their own site.
Recorded for completeness. Never counted as verified quality — the document is real, the chain of custody isn't independent.
Purity vs market
18 of 26 results sit within ±0.4 points of their market median.
3 further results are not plotted — no purity figure, or too few market results for that compound to compare against. They appear in the table below.
