Peptides BioResearch  is a full service Global  Wholesaler of Peptides. We pride ourselves on ensuring every peptide we sell are tested twice:  Once for Purity and once for Sterility.  Our scientists use the most advanced technology  for Sterility Testing using a combination of High-Performance Liquid Chromatography (HPLC) and Polymerase Chain Reaction (PCR ).  We not only test for the Purity of the peptides but also test for any  heavy metals, bacteria, mold and yeast. Once we complete the first stage of testing, we begin our second stage of Sterility Testing to ensure that  once the product is being delivered in its final form, the products leave our facility in a Sterile manner.  Our #1 priority as a company is to ensure we are delivering the best quality products to our customers.
