Peptide Science Basics: Evidence-First Education on Peptides and Health

Bottom line Ipamorelin and CJC-1295 are both growth hormone secretagogues that signal the pituitary gland to release more of the body's own growth hormone, but they work through two distinct receptor pathways. The single human study on CJC-1295, published in 2006, showed sustained GH and IGF-1 increases with no serious adverse reactions, but did not evaluate anti-aging, muscle, or fat-loss outcomes.
