Sterling Peptides

At Sterling Peptides we stand by our name, our products and our methodology. Sterling customer service, providing clinical grade products and a sincere commitment to maintaining a sterling reputation. Sterling Peptides was formed because we felt that the peptide industry, generally, didn’t have sufficient quality control. We wanted to give our customers the reassurance that throughout the process of manufacture, analysis, packaging and transit, each step was thoroughly evaluated and that strict measures were put in place to monitor and maintain composition and sterility. In line with this we commission a UK lab (Alta Bioscience) to run HPLC purification and mass spectrum analysis for each batch of manufactured peptides. Alta Bioscience is a highly reputable analysis company that was established in 1973. The test results can be found on our analysis page.
