What Are Peptides?
Peptides are short chains of amino acids — typically between 2 and 50 amino acids in length — that act as signaling molecules in the body. Unlike larger proteins, peptides are small enough to penetrate tissues and trigger specific biological responses, from stimulating growth hormone release to accelerating wound healing.
Researchers and health optimizers use synthetic analogs of naturally occurring peptides to target specific pathways: tissue repair (BPC-157, TB-500), fat metabolism (AOD-9604, Semaglutide), growth hormone secretion (Ipamorelin, CJC-1295), neuroprotection (Selank, Semax), and more.
At Peptide Breakdown, we analyze the actual research behind each peptide — mechanisms of action, clinical trial data, community-reported dosage protocols, and safety profiles. Every article is cross-referenced with peer-reviewed literature and written for an audience that demands substance over marketing.
