CJC-1295 (no DAC) + IPA: What It Is, How It Works & What the Research Shows
Overview
This blend combines two growth hormone secretagogues that work through different receptors. CJC-1295 without DAC (modified GRF 1-29) is a GHRH analog that signals the pituitary to release growth hormone, with a half-life of about 30 minutes. Ipamorelin activates the ghrelin receptor, triggering a growth hormone pulse with little effect on cortisol or prolactin. Studies of GHRH and ghrelin-pathway agonists given together show a synergistic, larger GH release than either alone, which is the rationale for pairing them.
Why researchers study it
Bigger GH pulse
Two pathways together release more GH than either alone.
Body composition
Explored for lean mass and fat loss via GH and IGF-1.
Sleep & recovery
Studied for deep sleep and recovery tied to nightly GH.
How it works
Growth-hormone signaling peptide blend. Combination dosing is not clinically established.
Adamantane & the blood–brain barrier
Chemically attaching an adamantane group to a peptide can increase its lipid (fat) solubility. Researchers hypothesize that this modification may help certain compounds cross the tightly regulated blood–brain barrier. The effect depends on the specific modified molecule; greater lipid solubility alone does not establish brain delivery or clinical benefit. This does not apply automatically to the unmodified peptide and is not a reconstitution additive.
What the research shows
- Growth-hormone signaling is the intended research target of this combination; clinical recovery or muscle-gain benefits are not established here.
- Benefits of a component do not demonstrate benefits of the finished blend.
Typical protocol
Reconstitute a 10 mg vial with 3 mL bacteriostatic water for 3.3333 mg/mL. Typical range: 100–600 mcg 1–3x daily (am/workout/pm) · 5 on 2 off or daily, 3–6 months · fasted.
Common stacks
- CJC-1295/Ipamorelin + AOD-9604 — Adds a lipolytic GH fragment to a GH-pulse blend.
Potential benefits & side effects
Potential benefits
- Deeper, more restorative sleep
- Improved recovery from training
- Gradual improvements in body composition (more lean mass, less fat)
- Better skin, hair and overall vitality reported over longer cycles
Side effects
- Injection-site redness or irritation
- Water retention, tingling or numbness in hands
- Head rush, flushing or lightheadedness shortly after dosing
- Increased hunger (more with ghrelin-pathway peptides)
- Higher blood sugar at larger doses — monitor glucose and IGF-1
Lifestyle factors
- Sleep: aim for 7–9 hours; the largest natural GH pulse happens in deep sleep.
- Fasted dosing: dose away from meals — elevated insulin and carbs blunt the GH pulse.
- Training: pair with resistance training and real recovery days.
- Protein: keep protein intake adequate to support lean mass.
- Consistency: dose at the same time each day and rotate injection sites.
