CJC-1295 without DAC Dosage Protocols: All Vial Sizes
CJC-1295 without DAC (also called Modified GRF 1-29) is a 30-amino-acid synthetic GHRH analog with a half-life of ~30 minutes. It produces a discrete GH pulse rather than sustained elevation.
Choose Your Vial Size
| Vial | Final volume | Concentration | One U-100 unit | |
|---|---|---|---|---|
| 5 mg | 3 mL | 1.67 mg/mL | 16.67 mcg in 0.01 mL | Open protocol → |
| 10 mg | 3 mL | 3.33 mg/mL | 33.33 mcg in 0.01 mL | Open protocol → |
Doses are the same research amounts across sizes; the vial size changes the concentration, so syringe units differ. Always use the table for your exact vial.
Storage Instructions
| State | Temperature | Duration |
|---|---|---|
| Lyophilized | −20°C (−4°F) | Up to 24 months, dry & dark |
| Reconstituted | 2–8°C (35–46°F) | Up to 28 days, protect from light |
Important Notes
How This Works
CJC-1295 without DAC contains the same four stabilizing amino acid substitutions as the DAC version (D-Ala2, Gln8, Ala15, Leu27) but lacks the albumin-binding linker. The result is a stable, short-acting GHRH analog producing a discrete GH pulse over ~30 minutes.
Common practice combines CJC-1295 with ipamorelin (a GHRP) — the GHRH stimulates GH release while the GHRP synergistically amplifies it, mimicking the body’s natural feedback patterns.
Potential Benefits & Side Effects
Potential Benefits
- Discrete pulsatile GH release mimicking physiological pattern.
- Often combined with ipamorelin for synergistic GH pulses.
- Improvements in sleep quality reported.
- Body composition and recovery effects via sustained protocols.
Side Effect Profile
- Injection-site reactions.
- Mild head flushing or fullness post-dose.
- Transient water retention.
- Hunger increase (some users).
Lifestyle Factors
- Avoid eating for 30+ min after injection — meals blunt GH release.
- Pre-bed dosing aligns with natural GH pulse during slow-wave sleep.
- Resistance training amplifies anabolic effects.
Injection Technique
- Subcutaneous into abdomen, thigh, or upper arm.
- Rotate sites with each dose.
- 90° angle with short insulin needle.
