How they differ

These act on two different receptors in the growth hormone system. CJC-1295 is a modified analogue of growth hormone-releasing hormone (GHRH) that acts on the GHRH receptor. Ipamorelin is a small growth hormone secretagogue that acts on the ghrelin receptor (GHS-R1a). Neither is FDA-approved, and human evidence for both is limited to early studies.

What each one is

CJC-1295: Synthetic growth hormone-releasing hormone analogue; DAC and non-DAC variants are chemically distinct. Molecular weight, sequence, research history, human evidence and regulatory status.

Ipamorelin: Synthetic pentapeptide studied as a ghrelin receptor agonist / growth hormone secretagogue. Molecular weight, sequence, research history, human evidence and regulatory status.
