Ipamorelin vs CJC-1295
Ipamorelin and CJC-1295 are the two halves of the most-cited growth-hormone research pairing. They are compared constantly because they are not really competitors — they act on two different receptors and are most often studied together. Understanding the split is the point of the comparison.
Ipamorelin
A selective ghrelin-receptor agonist (GH secretagogue) studied for clean GH pulses.

SIDE BY SIDE
| Ipamorelin | CJC-1295 | |
|---|---|---|
| Class | GH secretagogue (ghrelin-receptor agonist) | GHRH analog (growth-hormone-releasing hormone) |
| Receptor | Ghrelin / GHS-R | GHRH receptor |
| Studied effect | Triggers a pulse of GH release | Raises the amplitude / baseline of GH release |
| Selectivity | Highly selective — minimal effect on cortisol or prolactin in studies | Acts on the GHRH axis; often studied with DAC for longer action |
| Research role | The "pulse" half of the classic pairing | The "baseline" half of the classic pairing |
| Commonly paired with | CJC-1295 (synergistic GH research stack) | Ipamorelin (synergistic GH research stack) |
WHEN TO RESEARCH WHICH
Ipamorelin is a selective ghrelin-receptor agonist (a GH secretagogue) studied for clean, pulse-like GH release. CJC-1295 is a GHRH analog studied for raising the baseline of that release. Research protocols cite the CJC-1295 + Ipamorelin combination because a GHRH analog and a secretagogue act synergistically. We stock Ipamorelin; CJC-1295 is a reference comparison here.
FREQUENTLY ASKED
What is the difference between Ipamorelin and CJC-1295?
Ipamorelin is a ghrelin-receptor agonist (a GH secretagogue) studied for triggering pulses of growth-hormone release. CJC-1295 is a GHRH analog studied for raising the baseline of that release. They act on different receptors, which is why they are usually studied together.
Why are Ipamorelin and CJC-1295 combined in research?
A GHRH analog (CJC-1295) and a secretagogue (Ipamorelin) act synergistically on the growth-hormone axis, so the combination is the most-cited GH research stack. Both are for research purposes only.
Do you stock both?
