Know Your Peptides
Deep-dive research guides organized by what each compound is and what laboratory pathways it is studied for. Browse by category or open any peptide profile.
What are research peptides?
Peptides are short chains of amino acids that act as biological signals — hormones, neuromodulators, growth factors, and metabolic messengers. Research peptides let laboratories study one pathway at a time with high purity, defined sequences, and batch COAs.
Physis organizes the catalog by primary research domain: healing, metabolic, skin, longevity, cognitive/sleep, and melanocortin pathways — so you can match a study design to the right tool compound.
