CJC-1295 (No DAC) vs CJC-1295 + Ipamorelin
CJC-1295 (No DAC) and CJC-1295 + Ipamorelin are studied in overlapping research areas, which is why they are frequently compared. This is a neutral side-by-side reference drawn from published preclinical literature and laboratory handling data.
How they actually differ
Comparing the two: CJC-1295 (No DAC) is ghrh(1-29) tetra-substituted analogue (dac-free), while CJC-1295 + Ipamorelin is combination — ghrh(1-29) analogue plus selective ghrelin-receptor agonist — different molecular classes with different handling consequences; their leading degradation routes differ (deamidation at asn/gln residues over long solution storage. for CJC-1295 (No DAC), independent degradation of the two components at different rates, which is the defining stability characteristic of any blend. for CJC-1295 + Ipamorelin), so the storage precautions that matter are not the same; their practical working windows differ once reconstituted. The sections below set out each in full.
CJC-1295 (No DAC) — origin
CJC-1295 without DAC is the first 29 residues of growth-hormone-releasing hormone carrying four stabilising substitutions (D-Ala2, Gln8, Ala15, Leu27) that resist DPP-4 cleavage. Omitting the Drug Affinity Complex — the albumin-binding element of the DAC version — gives it a short half-life, which is the property researchers study it for.
CJC-1295 + Ipamorelin — origin
This is a two-compound blend studied for complementary mechanisms rather than a single molecule. CJC-1295 is a modified GHRH(1-29) fragment with four amino-acid substitutions that resist enzymatic degradation. Ipamorelin is a pentapeptide ghrelin-receptor agonist notable for its selectivity — it was specifically developed to stimulate GH release without the cortisol and prolactin effects of earlier secretagogues like GHRP-6.
CJC-1295 (No DAC) research themes
Studied for prompting growth-hormone release in short, physiological pulses via the GHRH receptor.
The four substitutions are studied for extending the molecule beyond the minutes-long survival of native GHRH.
Frequently studied alongside ghrelin-receptor secretagogues such as Ipamorelin, which recruit a second GH-release pathway.
CJC-1295 + Ipamorelin research themes
GHRH-receptor and ghrelin-receptor agonism act through different mechanisms, which is the rationale for pairing them.
Developed specifically for GH release with minimal cortisol and prolactin effects — its defining pharmacological feature.
Studied for effects on the pattern of GH secretion rather than continuous elevation.
A common endpoint in the preclinical literature for GH-axis compounds.
CJC-1295 (No DAC) handling
- Reach room temperature before opening.
- Swirl to dissolve; do not shake or vortex — foam indicates interfacial stress on the helix.
- Aliquot and refrigerate; never re-freeze reconstituted solution.
CJC-1295 + Ipamorelin handling
- Confirm whether the labelled mass is total blend mass or per-component before calculating concentration.
- Reconstitute the full vial rather than attempting to subdivide dry material — the two components will not partition evenly in powder form.
- Protect from light and refrigerate.
