CJC-1295 & Ipamorelin: A Research Overview
CJC-1295 and Ipamorelin are two distinct peptides that are almost always discussed — and researched — together. This is a factual overview for a research audience: what each one is, why they're paired, the DAC distinction people ask about, and how to confirm the vial matches its label. It is not medical guidance and makes no claim about any effect in humans.
Two different peptides, one common pairing
- CJC-1295 is a GHRH analogue — a synthetic modification of growth-hormone-releasing hormone, studied for its stability relative to native GHRH.
- Ipamorelin is a selective GHRP (a ghrelin-receptor agonist) — a short pentapeptide studied in a different but complementary signalling pathway.
They're frequently researched as a blend because they act on two separate mechanisms, which is why "CJC-1295 / Ipamorelin" is usually written as a pair.
| CJC-1295 | Ipamorelin | |
|---|---|---|
| Class | GHRH analogue | GHRP (ghrelin-receptor agonist) |
| Peptide length | ~29–30 residues (mod GRF 1-29) | 5 residues (pentapeptide) |
| Approx. molecular weight | ~3368 g/mol (no-DAC) | ~712 g/mol |
| Common variants | With DAC (long-acting) · No-DAC (mod GRF 1-29) | Single form |

DAC vs no-DAC — the distinction people ask about
CJC-1295 is studied in two forms. The DAC (Drug Affinity Complex) version is engineered to be longer-acting; the no-DAC form (often labelled mod GRF 1-29) is shorter-acting. They are different molecules with different molecular weights, so a CoA should make clear which one a vial actually contains — another reason batch documentation matters.
Why verification matters
A blend makes verification harder, not easier: you're now trusting the identity, purity and ratio of two compounds at once. None of that is visible in the vial. What settles it is documentation — identity by mass spectrometry, purity by HPLC, tied to your specific lot.
How DNR handles it
Every CJC-1295 / Ipamorelin lot we supply ships with a batch-specific Certificate of Analysis you can verify on our site before you order. Purity is specified at ≥98% and confirmed on the lot's own CoA.
