CJC-1295 vs Ipamorelin
Medically reviewed by the Rite Aid Health Team · Last updated August 14, 2026
CJC-1295 and ipamorelin are usually compared to understand their jobs inside a stack. CJC-related peptides act at the growth-hormone-releasing hormone receptor. Ipamorelin acts at the ghrelin receptor. The first practical question is whether “CJC-1295” means long-acting CJC-1295 with DAC or short-acting Mod GRF 1-29.

At a glance
| Comparison | CJC-1295 | Ipamorelin |
|---|---|---|
| Common goal | Set the GHRH side of a growth-hormone pulse | Add the ghrelin-receptor side of a pulse |
| Mechanism | GHRH analog | Selective GHRP |
| Evidence | Small human pharmacology studies with DAC. Human CJC-1295 study | Preclinical selectivity research and a human intravenous ileus trial. Selectivity study Human ileus trial |
| Formulation | DAC form lasts days; “no DAC” usually means Mod GRF 1-29 | One commonly used molecular name |
| Route and timing | A clinic guide reports no-DAC use at bedtime and long-acting DAC use weekly. Clinic practice guide | The same guide emphasizes bedtime, with more-frequent patterns also described. Clinic practice guide |
| Reported dosage | BHRC reports 100 to 300 mcg per no-DAC dose or 1 to 2 mg of DAC once or twice weekly. Clinic practice guide | BHRC reports 100 to 300 mcg per dose in its combined protocols. Clinic practice guide |
| Side effects and monitoring | IGF-1, glucose, swelling, headaches, joint or nerve symptoms, and injection reactions | Similar growth-hormone-axis checks |
| Access and status | No FDA-approved drug product | No FDA-approved drug product |
When the CJC-related component is considered
The CJC-related peptide supplies the releasing-hormone signal. DAC is selected for long exposure, while Mod GRF 1-29 is selected for a short pulse. Those formulations should not share one dosage schedule.
When ipamorelin is considered
Ipamorelin supplies the second receptor signal and is typically timed with a short-acting GHRH analog. It can also appear alone in reported practice, although clinical outcome evidence remains limited.
Why they are commonly combined
Two receptor signals can produce a larger hormone pulse than either signal alone. This pharmacology explains the stack, while direct trials have not established better sleep, recovery, muscle, or fat-loss outcomes.

FAQ
No. Products called no DAC usually contain Mod GRF 1-29, a short-acting molecule with a different schedule.
Reports generally treat short-acting Mod GRF 1-29 and ipamorelin as more frequent components than CJC-1295 with DAC. Exact intervals vary and are not evidence-based wellness instructions.
