peptides research: independent notes on vendors & the science of polypeptides

simple peptides co is a personal peptides research site. It covers two things researchers actually ask: who sells what — 22 vendor brand records built from public documentation, certificates of analysis and third-party testing practice — and what the molecules are, from the polypeptide and peptide bond to synthesis and analysis. We sell nothing, link no sellers, and give no medical or laboratory advice — every page is an evidence-graded summary of public documents.
