GH Optimization Stack (CJC-1295 + Ipamorelin)
Pulsatile GH release via dual-mechanism GHRH + ghrelin receptor stimulation for lean mass, sleep, and recovery.
Growth hormone & body composition
Intermediate
Cycle: 12 weeks on, 4 weeks off
Overview
CJC-1295 (no-DAC) is a short-acting GHRH analogue; ipamorelin is a selective ghrelin receptor agonist. Combined they produce a larger, more physiological GH pulse than either alone, without the cortisol and prolactin spikes seen with GHRP-2/6. Timing matters — doses must be on an empty stomach to avoid insulin blunting the GH response.
Dose schedule
| Phase | Dose & route | Notes |
|---|---|---|
| Weeks 1–12 | Pre-bed: CJC-1295 no-DAC 100 mcg + Ipamorelin 200 mcg SC. Pre-breakfast (optional): same dose on empty stomach. | Nightly dose is non-negotiable — overlaps with the natural GH pulse during slow-wave sleep. 2–3 hours empty stomach before and 30 min after injection. |
| Weeks 13–16 | No peptides. | Receptor sensitivity reset. GH axis recovery takes 2–3 weeks. |
| Alternative long-acting | CJC-1295 with DAC 2 mg SC weekly + Ipamorelin as above. | DAC version produces sustained GH elevation rather than pulses. Less physiological, more insulin resistance risk. Not preferred for beginners. |
Bloodwork cadence
| Timing | Panel |
|---|---|
| Baseline | IGF-1, fasting glucose, HbA1c, lipid panel, TSH, cortisol AM |
| Week 4 | IGF-1 (dose-finding target: upper quartile of age-adjusted range) |
| Week 12 | IGF-1, fasting glucose, HbA1c, lipid panel |
| Off cycle | IGF-1 to confirm return to baseline |
Expected timeline
- Week 1
- Deeper sleep often reported within 3–5 nights.
- Week 2
- Mild water retention in hands/feet common. Subsides by week 3.
- Week 4
- IGF-1 should be climbing. Recovery between workouts improved.
- Week 8
- Body-composition changes become visible. Visceral fat reduction documented at this stage.
- Week 12
- End of cycle. Expect gradual loss of effects over 2–3 weeks after stopping.
Red flags — stop and reassess
- Carpal tunnel symptoms, joint pain, or persistent water retention — reduce dose by 50%.
- Fasting glucose creeping above 100 mg/dL — pause and reassess diet/insulin sensitivity.
- IGF-1 above upper limit of age-adjusted range — reduce dose or add rest days.
Contraindications
- Active cancer (GH/IGF-1 axis stimulation).
- Uncontrolled diabetes.
- Diabetic retinopathy.
- Pregnancy.
