CJC-1295 + Ipamorelin Dosage Chart
The CJC-1295 (no DAC) + Ipamorelin pairing is the canonical research GH stack: a short-acting GHRH analog combined with a selective ghrelin receptor agonist. CJC-1295 (no DAC) PK was characterized in Teichman et al. 2006 (PMID 16352683). Ipamorelin's selective GH-releasing profile was established in Raun et al. 1998 (PMID 9849822).

Dosage Protocols
Each row reflects a common research protocol variant. These are reference ranges derived from published literature and community research — not medical guidance.
Protocol 1
Standard Research Protocol
Dose
CJC-1295 (no DAC) 100mcg + Ipamorelin 100mcg, 1x daily before sleep
Duration
12-16 weeks
Single-pulse pre-bed protocol. Empty stomach (3+ hours fasted) to avoid blunting the GH pulse. The two compounds can be drawn into the same syringe.
Protocol 2
Multi-Pulse Protocol
Dose
100mcg of each, 2-3x daily (AM, mid-day, pre-bed)
Duration
12-16 weeks
Multi-pulse pattern aligned with the short half-life of CJC-1295 without DAC. Each pulse needs an empty-stomach window. Common research pattern in published peptide literature.
Protocol 3
Elevated Protocol
Dose
CJC-1295 200mcg + Ipamorelin 300mcg pre-bed
Duration
8-12 weeks
Higher per-pulse dose. Ipamorelin remains GH-selective at 300mcg without significant cortisol or prolactin elevation per Raun 1998. Limit duration to manage receptor desensitization.
Protocol 4
Saturation Dose Reference
Dose
Ipamorelin up to 1mcg per kg bodyweight
Duration
Per-pulse
Saturation-curve research suggests diminishing GH response above ~1mcg/kg per pulse. Useful as an upper-bound reference, not a target dose.
Protocol 5
Stacked GHRH Variant
Dose
Add Tesamorelin 1mg or Sermorelin 200mcg in place of CJC-1295
Duration
8-12 weeks
Some researchers swap in Tesamorelin (longer plasma exposure) or Sermorelin (shortest acting GHRH-1-29). Mechanism overlaps; do not stack all three GHRH analogs simultaneously.

Storage
Handling Notes
Both peptides lyophilized: 2-8°C preferred, -20°C for long-term storage. Reconstituted: refrigerate at 2-8°C. CJC-1295 (no DAC) use within 14 days; Ipamorelin use within 28 days. Protect from light.
Research Considerations
Cautions
- CJC-1295 is sold in two forms: with DAC (drug affinity complex, ~6-8 day half-life) and without DAC (~30 min). This protocol is for the no-DAC form. Do not interchange dosing.
- Empty-stomach administration matters. Carbohydrate or insulin spikes within 60 minutes blunt the GH pulse.
- Ipamorelin is GH-selective in published research, but stacking with non-selective GHRPs (GHRP-2, GHRP-6) reintroduces cortisol and prolactin effects.
- Discontinue at least 48 hours before any GH or IGF-1 lab work to avoid artificially elevated readings.
