What Is CJC-1295?

CJC-1295 is one of the most studied growth-hormone-releasing peptides, usually mentioned right next to Ipamorelin. Here is what it is.

5 min read Reviewed for accuracy Research Use Only
The short answer

CJC-1295 is a synthetic analog of growth-hormone-releasing hormone (GHRH). It is studied in research as a growth hormone secretagogue and is often studied alongside Ipamorelin. Research use only.

What CJC-1295 is

CJC-1295 is a peptide modeled on GHRH, the natural signal that prompts growth hormone release. It is designed to be longer-acting than natural GHRH, which is part of why it draws research interest. Some versions are described as "with DAC" or "no DAC," referring to a modification that changes its duration.
