Peptides 101
Start here. Plain-English foundations for reading peptide research critically.
What are peptides?
Peptides are short chains of amino acids that act as signals in the body.
Peptides vs proteinsThe line between peptide and protein is mostly about length and folding.
How peptide drugs are developedFrom mechanism and preclinical work to human trials and approval.
Routes studied in peptide researchInjection, nasal, oral, and topical — why route matters.
Peptide half-life explainedWhy many peptides are cleared quickly, and how that's engineered around.
Purity, sterility, and Certificates of AnalysisWhy '99% pure' on a COA does not mean 'safe'.
Why animal evidence isn't human evidenceMost peptide hype rests on animal data that may not translate.
Approved drugs vs research compoundsThe most important distinction on this site.
