Complete evidence-based CJC-1295 dosing protocol for 2026. Updated reconstitution steps, injection guidance, and cycle protocols.
Common dose: 100–300 mcg | Frequency: 2–3x daily or once before bed
Half-life: 30 min (no DAC) / 7–8 days (with DAC) | Category: Growth Hormone
Injection sites: Subcutaneous, abdomen
CJC-1295 is a synthetic analogue of Growth Hormone Releasing Hormone (GHRH) with significantly extended half-life. Without DAC (~30 min): dosed 2–3x daily. With DAC (7–8 days): once weekly. Stimulates the pituitary to release GH in a natural pulsatile pattern. The CJC-1295 + Ipamorelin combination is the most popular peptide stack for anti-aging, body composition, and recovery. Benefits include improved fat metabolism, lean muscle, better sleep, and anti-aging effects on skin and collagen. Track your CJC-1295 dosing schedule with the DoseIQ app.
Below are evidence-based CJC-1295 dosing protocols for different experience levels and goals. Always start at the lowest effective dose and assess tolerance before increasing.
Proper reconstitution is critical for accurate dosing. Follow these steps carefully:
Use this table to determine your exact injection volume based on vial size and BAC water amount:
| Vial Size | BAC Water | Concentration | Low Dose Vol | High Dose Vol |
|---|---|---|---|---|
| 2 mg | 2 mL | 1,000 mcg/mL | 0.10 mL | 0.20 mL |
| 5 mg | 2 mL | 2,500 mcg/mL | 0.04 mL | 0.08 mL |
| 2 mg | 1 mL | 2,000 mcg/mL | 0.05 mL | 0.10 mL |
Recommended sites: Subcutaneous, abdomen
Rotate injection sites to prevent scar tissue buildup. Clean the injection site with an alcohol swab before injecting. Use a 27-29 gauge insulin syringe for subcutaneous injections. Pinch the skin, insert needle at 45-90°, and inject slowly.
Lyophilized (powder) form: Refrigerate at 36–46°F (2–8°C). Protect from light. Most peptides remain stable for 1–2 years unreconstituted.
Reconstituted solution: Refrigerate immediately after mixing. Use within 4 weeks typically. Do not freeze reconstituted peptides — this may damage the peptide structure.
