Peptides are short chains of amino acids that act as signaling molecules in the body. This category covers research peptides relevant to physique, recovery, and anti-aging — including GHRPs (growth hormone releasing peptides), GHRH analogs (mod GRF, CJC-1295), BPC-157 for healing, TB-500, melanotan, and more. Mechanism of action, dosing protocols, research uses, and safety considerations.
