What is CJC-1295 (No DAC)?
Amplified Natural GH Pulse
CJC-1295 without DAC — also called Mod GRF (1-29) — is a modified growth-hormone-releasing hormone fragment. Four amino-acid substitutions extend its half-life past native GHRH while keeping the release pattern pulsatile rather than continuous, which is why it is studied as a pairing partner for ghrelin agonists.
Areas of Research Interest
Summarized from published research findings. Not medical guidance or prescribing information.
Pulsatile Release
Preserves the natural episodic GH rhythm rather than producing a flat serum elevation.
Recovery Endpoints
Studied for post-exertion recovery and lean-tissue maintenance in combination protocols.
Sleep Architecture
Evening administration is examined against slow-wave sleep measures.
Lipolysis Models
GH-axis elevation is associated with increased fat-substrate utilization.
Synergy
Most published designs pair it with Ipamorelin for an amplified combined pulse.
Short Half-Life
No-DAC form clears quickly, avoiding the sustained saturation seen with DAC variants.
Reconstitution
- 5 mg vial + 2 mL bacteriostatic water = 2.5 mg/mL
- 2 mg vial + 2 mL bacteriostatic water = 1.0 mg/mL
- At 2.5 mg/mL, 1 unit on a U-100 syringe = 25 mcg
Suggested research protocol
- Route studied: subcutaneous, typically administered together with Ipamorelin in the same syringe.
- Timing: before sleep and/or post-exertion, away from food.
- Cycle: 5 days on / 2 days off, in 8–12 week research blocks.
- Refrigerate after reconstitution; use within 30 days.
Dosing Reference
| Phase | Per administration | U-100 units @ 2.5 mg/mL |
|---|---|---|
| Introductory | 100 mcg | 4 units |
| Standard | 100–200 mcg | 4–8 units |
| Paired with Ipamorelin | 100 mcg each | 4 units each |
Handling & Notes
- Food — particularly fats and carbohydrates — blunts the GH response; a fasted window is standard in study design.
- Transient flushing or head-rush sensations are logged and short-lived.
- Store lyophilized vials away from light.
