Peptides short chains of amino acids that act as signaling molecules in the body are gaining serious scientific attention for their role in supporting healthy aging, recovery, metabolic health, and overall wellness. While research varies in depth across compounds, several peptides stand out for their promising biological effects and longevity-related mechanisms. Among the most studied are peptides like GHK-Cu, known for its role in DNA repair and collagen synthesis; BPC-157, which has shown tissue-healing and anti-inflammatory properties in preclinical research; and Epitalon, a peptide linked to telomere maintenance and circadian regulation. Others include growth hormone secretagogues like CJC-1295 + Ipamorelin, which help optimize natural hormone signals, and mitochondrial regulators like MOTS-c, which support cellular energy and metabolic flexibility.
