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 614 certificates we hold. Ten of fourteen compounds test at or above their market median. The exception is a Tirzepatide lot at 98.77% — 1.04 points below the 99.81% median for that compound, and the only result here outside the corpus's middle 80%.
Evidence provenance
