CJC-1295 vs Ipamorelin: what is the difference?
CJC-1295 and Ipamorelin are almost always named together, and that is no coincidence: they belong to two different families within growth-hormone research. One mimics growth-hormone-releasing hormone, the other works through the ghrelin receptor. Here is the difference, factual and research-only.
| Property | CJC-1295 (without DAC) | Ipamorelin |
|---|---|---|
| Family | GHRH analogue | GHRP (ghrelin mimetic) |
| Point of focus in research | GHRH receptor | Ghrelin receptor (GHS-R) |
| Peptide type | Modified GHRH fragment (Mod GRF 1-29) | Selective pentapeptide |
| Research field | Growth-hormone secretagogues | Growth-hormone secretagogues, selectivity |
| Purity | ≥99% (HPLC + MS, Janoshik COA per batch) | ≥99% (HPLC + MS, Janoshik COA per batch) |
| Molecular weight | See COA per batch | 711.85 g/mol |
| Vial strength | 10 mg per vial | 10 mg per vial |
Two families, one research field
CJC-1295 is a GHRH analogue: it mimics growth-hormone-releasing hormone. Ipamorelin is a GHRP and has the ghrelin receptor as its point of focus. That is the core difference. They sit in the same research field but approach it along a different route — which is exactly why the literature so often puts them side by side.
In research Ipamorelin is known as the selective example within the GHRP family, as opposed to older GHRPs such as GHRP-2 and GHRP-6. Want the overview? See the full range of growth-hormone peptides.
CJC-1295 with or without DAC
CJC-1295 comes in two variants: with and without DAC (Drug Affinity Complex). The DAC variant is designed to break down more slowly, which makes the two separate objects of study. The variant without DAC is also called Mod GRF 1-29.

Frequently Asked Questions
What is the difference between CJC-1295 and Ipamorelin?
CJC-1295 is a GHRH analogue that mimics growth-hormone-releasing hormone. Ipamorelin is a GHRP, a ghrelin mimetic with the ghrelin receptor as its point of focus. Two families within the same research field, along a different route.
Why are CJC-1295 and Ipamorelin studied together?
Because combinations of a GHRH analogue and a GHRP are a recurring subject in growth-hormone research. Peptide Lab also supplies that combination as a single blend, where the stated amount is the total across both components.
What does DAC mean in CJC-1295?
DAC stands for Drug Affinity Complex, a modification designed to make the molecule break down more slowly. CJC-1295 without DAC is also called Mod GRF 1-29. Both are separate objects of study and for research only.
