Ipamorelin is a third-generation growth hormone secretagogue (GHS) and a selective agonist of the ghrelin receptor. It is widely regarded as one of the cleanest GH-releasing peptides available due to its high selectivity and minimal side effects.
Ipamorelin selectively stimulates GH release from the pituitary gland without significantly affecting cortisol, prolactin, or ACTH levels — a key advantage over older GH secretagogues like GHRP-2 and GHRP-6. It is commonly combined with CJC-1295 for synergistic GH pulse amplification.
Users report improved sleep quality, enhanced muscle recovery, gradual improvements in body composition, and increased energy. Ipamorelin is often stacked with CJC-1295 for amplified GH pulses. Results typically become noticeable after 4–8 weeks.
