At RCpeptides, transparency and quality are our top priorities. Every batch of our research peptides is independently tested by certified third-party laboratories to ensure the highest standards of purity, identity, and consistency.
We believe researchers deserve full confidence in the products they use — that’s why we make all test results publicly available. On this page, you can find up-to-date Certificates of Analysis (COAs) and lab reports for each peptide we offer.
Independent lab testing guarantees that our products meet the exact specifications listed on our site. This level of transparency helps you make informed decisions for your research with verified, reliable compounds.
