1What Is CJC-1295?

CJC-1295 is a synthetic analog of Growth Hormone Releasing Hormone (GHRH) - a naturally occurring hormone that signals the pituitary gland to produce and release growth hormone (GH). Unlike natural GHRH, which breaks down within minutes, CJC-1295 is modified to last much longer in the body - studies have shown its effects persisting for days. It is studied for its potential to stimulate growth hormone release in research models. Available for in-vitro research purposes only.

3How It Works

The pituitary gland sits at the base of the brain and produces growth hormone, which regulates muscle growth, fat metabolism, bone density, and cellular repair. Under normal conditions, the hypothalamus sends GHRH signals to trigger GH release. CJC-1295 mimics these signals but is modified to avoid the enzymes that normally break down GHRH, dramatically extending its half-life. In animal studies, it has been shown to substantially elevate GH and IGF-1 (insulin-like growth factor 1, another key growth signal) levels.

4What Researchers Have Observed

💪
Growth Hormone Elevation in Human Studies
A Phase I/II clinical trial published in the Journal of Clinical Endocrinology & Metabolism (2006) showed CJC-1295 significantly increased GH and IGF-1 levels in healthy adult subjects over multiple weeks.
⏱️
Extended Duration of Action
Unlike natural GHRH (half-life: ~7 minutes), CJC-1295 DAC (with Drug Affinity Complex) has a half-life of approximately 8 days, allowing for once-weekly or twice-weekly dosing in research protocols.

These findings are from pre-clinical and early-phase research. Results in human subjects have not been established.

6Common Questions

What is the difference between CJC-1295 with and without DAC?↓
DAC stands for "Drug Affinity Complex" - a modification that allows the peptide to bind to albumin (a blood protein), dramatically extending its half-life from about 30 minutes to approximately 8 days. CJC-1295 without DAC (also called Mod GRF 1-29) has a shorter duration and is typically used for more pulsatile GH release in research models.
Is CJC-1295 the same as Sermorelin?↓
Both are GHRH analogs, but they are structurally different compounds. Sermorelin is a shorter fragment (29 amino acids) of GHRH and has a much shorter half-life. CJC-1295 is modified for greater stability and longer duration of action.
