We partner with and have built strong working relationships with industry-leading and reputable labs like Trustpointe Analytics to perform the mass spectrometry testing to ensure maximum quality and longevity in the product as well as ensuring maximum purity and accurate peptide strength. We follow ANSI Z1.4 guidelines on batch analysis and analyze multiple vials to capture more accurate and precise “representative sample” and ultimately a better more reliable product. We also perform routine United States Pharmacopeia (USP) batch tests to include USP <71> sterility and USP <85> bacterial endotoxin analysis. All of these different steps ensures our research peptides are the highest quality, most precise and can be applied toward academic benefit with confidence. Below are the collection of current and historical certificates of analysis (COAs TexBiomed Peptides) that represent the quality and purity of our research chemicals.
