Bionexis Peptides bionexis Peptides ('UK Laboratory') sells a broad range and claims 'HPLC & LC-MS verified, COA per batch, ≥99% purity,' but names no laboratory and shows no company details on its homepage. Domain registered January 2026. Until it publishes an own-name certificate from a named independent lab you can verify, the purity figure is its own word.
The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers. No public BPC-157 price feed was available for this vendor at audit.
