  • Research quality is another dimension where peptides vs steroids comparison is relevant. Peptide purity is typically verified by HPLC analysis and reported as a percentage — high-quality research peptides from reputable suppliers should demonstrate 98%+ purity by HPLC. Mass spectrometry (MS) confirms molecular identity. Understanding how to read a Certificate of Analysis (COA) is essential for researchers. Our guide to reading peptide COAs explains what to look for in purity documentation.
  • For both peptides vs steroids research, sourcing from suppliers who provide third-party verified purity documentation is essential for experimental validity. PSPeptides provides third-party HPLC and MS documentation for all research compounds.
