StandardsA line-by-line walkthrough of a peptide certificate of analysis — batch number, purity, identity, and the fields that separate a real COA from a marketing image.
Read overview
StandardsTwo analytical methods answer two different questions about a research peptide. Here is what HPLC and mass spectrometry each measure — and why a real COA uses both.
Read overview
Standards"99% pure" is the most quoted number in the peptide market — and the most misunderstood. Here is what the figure measures, what the missing 1% is, and why the method matters more than the number.
Read overview
EducationTemperature, light, and moisture quietly determine whether a research peptide stays intact. A general laboratory guide to storing lyophilized and prepared compounds.
Read overview
Goal GuideStart from the question you want to study, not the chemistry. A framework for navigating the catalog by research outcome — metabolic, recovery, longevity, and performance.
Read overview
StandardsIn-house numbers grade the vendor's own homework. Independent testing is what makes a purity claim credible — here is why it matters and how to check that it is real.
Read overview
EducationA peptide's quality is set at manufacture but preserved in transit. Here is what cold-chain shipping is, why heat is the enemy, and how proper packaging protects research-compound integrity.

StandardsProGrade organizes its catalog by research outcome, not chemical class. Here is what MODE-M, MODE-R, MODE-L, and MODE-P stand for — and why it makes research easier.
Read overview
StandardsWhat a certificate of analysis actually documents, how HPLC and mass spectrometry establish purity and identity, and why per-batch COAs matter.
