CJC-1295 is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
The most common research dosage for CJC-1295 is 100-300 mcg, administered 1-3 times daily, typically before bed via subcutaneous injection. Typical cycles run 8-12 weeks, often paired with Ipamorelin. With a half-life of ~30 minutes (no DAC), ~8 days (with DAC), timing matters for optimal results.
What Is CJC-1295 and Why Does Dosing Matter?
CJC-1295 (CJC-1295 (Modified GRF 1-29)) is a Growth Hormone Releasing Hormone (GHRH) analog. Synthetic peptide analog of GHRH (first 29 amino acids) with four amino acid substitutions for enhanced stability. Getting the dosage right is critical — too little may produce no measurable effect, while excessive amounts increase risk without proportional benefit.
The standard research dosage for CJC-1295 has been established through preclinical studies and community protocols. This guide covers the evidence-backed dosing range, timing, and cycle structure.
What Is the Recommended CJC-1295 Dosage?
The most widely used CJC-1295 dosage is 100-300 mcg, administered 1-3 times daily, typically before bed via subcutaneous injection.
Beginners should start at the lower end of this range and titrate upward only if needed. The half-life of CJC-1295 is ~30 minutes (no DAC), ~8 days (with DAC), which directly determines how often you need to dose to maintain stable blood levels.
For CJC-1295 specifically, the 8-12 weeks, often paired with Ipamorelin cycle length is standard. Longer isn't always better — Growth Hormone Releasing Hormone (GHRH) analog compounds require cycling to maintain receptor sensitivity.
When Should You Dose CJC-1295?
With a half-life of ~30 minutes (no DAC), ~8 days (with DAC), timing your CJC-1295 administration affects peak blood levels. Most protocols call for 1-3 times daily, typically before bed.
For peptides administered before bed (common with GH-related compounds), the goal is to amplify the natural nocturnal growth hormone pulse. For healing peptides, proximity to the injury site via local injection can improve outcomes.
Calculate Your CJC-1295 Dose

Open Calculator →How Do You Reconstitute CJC-1295?
CJC-1295 typically comes as a lyophilized (freeze-dried) powder. Reconstitute with bacteriostatic water — never saline or sterile water, as BAC water contains 0.9% benzyl alcohol that prevents bacterial growth and extends shelf life to 4-6 weeks.
Use our peptide dosing calculator to determine the exact amount of BAC water to add based on your vial size and desired dose per injection.
How Long Should a CJC-1295 Cycle Last?
Standard CJC-1295 cycles run 8-12 weeks, often paired with Ipamorelin. This timeframe is based on the compound's mechanism and the time needed to observe measurable effects.
Clinical research demonstrates significant increases in GH and IGF-1 levels in human subjects. Studies show improved body composition with increased lean mass and reduced body fat, particularly when combined with GHRP peptides like Ipamorelin.
What Side Effects Can Affect Dosing?
Possible water retention, tingling/numbness in hands (carpal tunnel-like), increased appetite, mild headache, and flushing at injection site. Effects are dose-dependent and typically subside with continued use.
If side effects emerge, the first step is typically reducing the dose rather than discontinuing entirely. Most CJC-1295-related side effects are dose-dependent.
How Does CJC-1295 Dosing Change When Stacking?
The gold standard stack is CJC-1295 + Ipamorelin — GHRH + GHRP together produce GH pulses far greater than either alone, through synergistic pituitary stimulation via two distinct receptor pathways.
When stacking, some researchers reduce individual peptide doses by 20-30% since synergistic effects mean full doses of each aren't always necessary.
What Is the Bottom Line on CJC-1295 Dosing?
Start at 100, dose 1-3 times daily, typically before bed, and run cycles of 8-12 weeks, often paired with Ipamorelin. Monitor your response and adjust within the established range.
Source matters — always use research-grade CJC-1295 from vendors with third-party COA testing. Underdosed or contaminated products are the most common reason for poor results.
