GHRH-receptor signal
CJC-1295 No DAC acts as a short-acting GHRH analog, encouraging pituitary somatotroph cells to synthesize and release growth hormone.
GHRH Analog + Selective Ghrelin-Receptor Agonist
CJC-1295 No DAC and Ipamorelin are commonly combined to stimulate growth-hormone release through complementary GHRH and ghrelin-receptor pathways. The blend is not FDA approved, has not been tested as a combination in a published randomized trial in healthy adults, and most dosing guidance comes from clinical practice and peptide communities.
CJC-1295 No DAC + Ipamorelin combines two growth-hormone secretagogues that act through different signaling pathways. CJC-1295 No DAC, also called Mod GRF 1-29, is a short-acting analog of growth hormone-releasing hormone (GHRH). Ipamorelin is a selective agonist of the ghrelin or growth-hormone secretagogue receptor.
GHRH signaling encourages pituitary cells to synthesize and release growth hormone. Ipamorelin acts through a separate receptor system to trigger release of stored growth hormone. Human physiology studies support synergy between these pathway classes, but no published randomized controlled trial has established the efficacy or safety of this specific blend in healthy adults.
The no-DAC peptide is short acting. CJC-1295 with DAC has a drug-affinity modification that extends its activity; results from long-acting CJC-1295 trials cannot be transferred directly to Mod GRF 1-29.
CJC-1295 No DAC acts as a short-acting GHRH analog, encouraging pituitary somatotroph cells to synthesize and release growth hormone.
Ipamorelin activates the growth-hormone secretagogue receptor through a complementary pathway that promotes release of stored GH.
The pairing is used to amplify endogenous GH pulses and downstream IGF-1 signaling rather than directly supplying exogenous growth hormone.
Human physiology supports pathway-level synergy, but the exact no-DAC and Ipamorelin blend has not been validated in a randomized efficacy trial.
The proposed benefits are linked to GH and downstream IGF-1 signaling. Claims for this exact combination rely heavily on physiology, individual-compound research, and community reports.
The intended effect is amplification of endogenous GH pulses. Human trials of long-acting CJC-1295 with DAC are not direct evidence for this short-acting blend.
Improved sleep is a common community report, but controlled studies have not shown that this blend improves sleep in healthy adults.
Users often describe less soreness and steadier recovery. Controlled trials have not shown accelerated recovery from this combination.
GH supports lipolysis, but visible fat loss is not guaranteed and depends on nutrition, training, sleep, and baseline hormone status.
Longer-term users report joint comfort and skin changes; these remain anecdotal and do not establish structural tissue repair.
Some users describe improved clarity or mood, but research on cognitive outcomes from the blend is sparse.

Wash your hands, clean the work surface, and wipe both vial stoppers with alcohol. Allow them to dry.
Use a new sterile syringe and needle to direct the selected volume of compatible diluent down the inside wall of the vial. A 10mg blend vial contains 5mg of each peptide; with 2mL, the concentration is 2.5mg/mL of each.
Swirl or roll the vial until the contents dissolve; do not shake.
Store refrigerated at 2–8°C (36–46°F) and protected from light when the product instructions support this. Record the reconstitution date in your research journal.
The following pairings are discussed in clinical practice or peptide communities; controlled studies of these combinations are lacking.
TRT and GH secretagogues act through different endocrine pathways. Combined use may increase fluid retention, sleep-apnea risk, glucose effects, and monitoring needs.
Delayed gastric emptying and reduced caloric intake can complicate timing, nutrition, glucose control, and recovery.
These compounds have different proposed targets and do not share the same fasting convention. No clinical studies evaluate the combination.
Mitochondrial peptides and GH secretagogues act through different proposed pathways; concurrent use remains experimental and unstudied.
Human safety data for long-acting CJC-1295 and Ipamorelin do not establish the safety of this no-DAC combination, its community doses, or long-term use in healthy adults. Unregulated injectable products also introduce sterility, impurity, and dosing risks.
We still consider the CJC-1295 No DAC + Ipamorelin combination the gold standard daily growth hormone stack. These two peptides work best as a team — running either one separately significantly reduces the effectiveness and you’re simply not maximizing the potential. Together they deliver reliable GH pulses, enhanced recovery, better sleep, and solid muscle preservation with a relatively favorable side effect profile.
The community keeps returning to this pairing because it simply works well across recomp, healing, and longevity goals. That said, it does tend to leave welts at injection sites for many users, so proper rotation and technique matter. More is not better here — stick to standard protocol dosing for optimal results without unnecessary sides.
Clean, consistent, and effective when used correctly. A foundational stack that remains hard to beat for everyday optimization.
