    THE SCIENCE

    Peptides, Explained

    Peptides are short chains of amino acids — signaling molecules that regulate specific biological pathways.

    01

    What They Are

    Short chains of 2 to 50 amino acids linked by peptide bonds. Distinct from full proteins in size and function. Act as biological messengers.

    02

    How They Work

    Peptides bind to specific receptors on cell surfaces, initiating cascades that regulate protein synthesis, cellular signaling, and receptor activity.

    03

    Why Categories Matter

    Different peptides target different receptors — GLP-1 for metabolic, BPC-157 for cytoprotection, CJC/Ipa for GH release. Category = mechanism.
