Peptides are short chains of amino acids that play important roles in biological signaling processes such as hormone regulation, tissue repair, metabolism, and cellular communication. In recent years, peptide compounds have gained significant attention in scientific research, fitness discussions, and metabolic studies.

This category includes a wide range of peptides often studied for areas such as body composition, recovery, anti-aging research, and metabolic function. However, many still remain investigational compounds and are not approved as medications for general medical use in most countries.
