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.
22 certificates on file — 14 independently sourced from TrustPointe Analytics LLC and Kovera Labs, not supplied by the vendor. Median purity 99.71%, against 99.68% across all 928 certificates we score. Nine of fourteen compounds test at or above their market median. The exception is a Tirzepatide lot at 98.77% — 1.03 points below the 99.80% median for that compound, and the only result here outside the corpus's middle 80%.
Evidence provenance
- 14 lab-sourced
- pulled from a testing lab's own public result database, keyed to the lab's reference number.
- 8 self-published
- COAs the vendor posted on their own site.
Counts as confirmed. Each one came from the lab's own public database — the laboratory is the publisher.
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
21 of 22 results sit within ±0.4 points of their market median.
