Frequently asked questions
What is a research peptide?
A peptide — a short chain of amino acids — sold as a Research Use Only chemical for laboratory study. Research peptides are not approved drugs and are not sold for human use.
How are peptides categorized on this site?
By primary research area: healing and recovery, GLP-1/metabolic, growth hormone axis, nootropic/neuro, skin and longevity, and sexual health. Categories reflect what the research literature investigates each compound for.
Where does the dosing information come from?
From published research literature and clinical trial protocols, presented as 'commonly referenced ranges.' Nothing on this site is a dosing recommendation.
