Ipamorelin vs CJC-1295: Mechanism and Cost per mg
Ipamorelin and CJC-1295 are the classic growth-hormone-axis research pairing. They are studied together precisely because they act on two different receptors that drive GH release.
Cost per milligram
Both are priced by the milligram, so you can compare what you actually pay, not just the sticker price.
| Ipamorelin | CJC-1295 (no-DAC) | |
|---|---|---|
| Receptor target | Ghrelin receptor (GHS-R) | GHRH receptor |
| Class | Growth-hormone secretagogue (GHRP) | GHRH analog, Modified GRF(1-29) |
| Peptide | Selective pentapeptide | Stabilized GHRH(1-29) fragment |
| Common study design | Paired with a GHRH analog | Paired with a secretagogue |
Ipamorelin is a selective growth-hormone secretagogue: it acts on the ghrelin receptor (GHS-R). CJC-1295 (no-DAC) is a GHRH analog, a stabilized version of the GHRH(1-29) fragment that acts on the separate GHRH receptor.
These are the two complementary arms of growth-hormone signaling, the secretagogue pathway and the GHRH pathway. Because they engage different receptors, the literature studies them as a pair far more often than as alternatives.
So the comparison isn't which one. It is what each receptor contributes, which is why this is one of the most common research stacks.

Common questions
What is the difference between ipamorelin and CJC-1295?
Ipamorelin is a growth-hormone secretagogue acting on the ghrelin receptor (GHS-R). CJC-1295 (no-DAC) is a GHRH analog acting on the GHRH receptor. They engage two different receptors on the GH axis, which is why they are commonly studied together.
How much do ipamorelin and CJC-1295 cost?
Both are priced by the milligram. The live cost per mg for each is shown above and on each product page, so you can compare the real per-mg cost directly.
