What is peptide research?
Peptide research is the scientific study of short chains of amino acids — typically 2 to 50 residues — and how they interact with receptors, enzymes, and signaling pathways in the body. Modern peptide research spans preclinical animal models, randomized clinical trials, mechanism-of-action work, and applied wellness research across recovery, longevity, metabolic health, cognition, skin, and the endocrine system.
Some peptides — like semaglutide, tirzepatide, octreotide, and teriparatide — are FDA-approved drugs with extensive clinical data. Others — like BPC-157, TB-500, MOTS-c, and epitalon — are widely discussed in wellness contexts but remain investigational with primarily preclinical evidence. This research hub indexes both, so you can evaluate the evidence base for any peptide you care about.
