The classic GHRH analog — no DAC, shorter action, and most effective paired up.
CJC-1295 (without DAC) is studied for natural, pulsatile growth hormone release. Here’s the protocol, the timing rules that actually matter, and what it stacks with.

Primary Benefits
- Stimulates natural growth hormone production (GHRH)
- Promotes lean muscle mass development and fat metabolism
- Accelerates recovery from training and soft tissue injury
- Supports skin rejuvenation and anti-aging effects
Mechanism of Action
CJC-1295 is a synthetic analog of Growth Hormone-Releasing Hormone (GHRH) with an extended half-life.
It binds to pituitary receptors to stimulate pulsatile GH release, which in turn increases circulating IGF-1. That leads to enhanced protein synthesis, cellular repair, lipolysis, and regenerative effects — without the side effects of exogenous GH.
Dosing & Protocol
Subcutaneous (SQ) Injection:
- Reconstitution:
- 2 mg vial → 2.0 mL bacteriostatic water (= 100 mcg per 10 units)
- 5 mg vial → 2.5 mL bacteriostatic water (= 200 mcg per 10 units)
- Daily Dose:
- 100–200 mcg
- Cycle:
- 5 days on / 2 days off
- 4–12 weeks
- Timing: Take 2 hours after your last meal, just before bed.
Potential Side Effects
- Mild irritation at the injection site
- Water retention or tingling in extremities (rare)
- Increased hunger or fatigue in some users
- Not suitable for individuals with active cancer or uncontrolled diabetes
Common Stacks
- With Ipamorelin: Synergistic GH-releasing stack (pulsatile)
- With BPC-157 or TB-500: For enhanced recovery and soft tissue repair
- With 5-Amino-1MQ: For metabolic enhancement and body recomposition
Notes
CJC-1295 can be used alone, but it’s most effective when stacked with a GHRP such as Ipamorelin for compounded GH release.
Keep the reconstituted solution refrigerated and use within 45 days unless the product label or protocol says otherwise. Avoid food intake within 2 hours prior to administration for optimal effect.
