Oxfordpeptidelabs openly does its testing 'in-house', i.e. the company selling the product also writes the certificate that says the product is good. There is no outside check anywhere in that loop; the purity figure is whatever they decide to print. Calling that a 'Certificate of Analysis' borrows the authority of independent testing while removing the one thing that gives it meaning, independence.
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.
