GHRH analog that signals the pituitary to release endogenous GH — available in sustained-release (DAC) and pulsatile (No-DAC) variants.
CJC-1295 is a growth hormone-releasing hormone (GHRH) analog that tells your pituitary gland to release its own growth hormone. It comes in two variants: CJC-1295 with DAC (Drug Affinity Complex) provides sustained GH elevation with weekly dosing, while CJC-1295 No-DAC (also called Mod GRF 1-29) produces natural pulsatile GH release with daily injections.
CJC-1295 acts on the GHRH receptor in the pituitary gland, stimulating the release of endogenous growth hormone. The DAC version binds to albumin in the bloodstream, extending its half-life and producing sustained GH elevation over days. The No-DAC version has a short half-life, mimicking the body's natural pulsatile GH rhythm.
| Tier | Dose | Frequency | Notes |
|---|---|---|---|
| Starting | 13 mcg/lb | Once weekly | Example: 180 lb = ~2.3 mg/week |
| Moderate | 27 mcg/lb | Once weekly | Example: 180 lb = ~4.9 mg/week |
Route: Subcutaneous injection
Cycle Length: 8–12 weeks
| Tier | Dose | Frequency | Notes |
|---|---|---|---|
| Starting | 100 mcg | Once daily (bedtime) | Begin here to assess tolerance |
| Moderate | 200 mcg | 2x daily (AM + pre-bed) | Standard protocol |
| High | 200 mcg | 3x daily (AM + pre-training + pre-bed) | Advanced — monitor IGF-1 |
Cycle Length: 8–12 weeks
Route: Subcutaneous injection
Best paired with: Ipamorelin (GHRH + GHS synergy)
Long-term risks mirror those of sustained GH elevation. Monitor IGF-1 levels at 6 weeks and adjust dose accordingly.
