How It Works
CJC-1295 is a 30-amino acid peptide analog of GHRH (growth hormone-releasing hormone) that binds to GHRH receptors on the pituitary gland, stimulating GH production. The no-DAC version (also called Mod GRF 1-29) has a half-life of about 30 minutes, producing natural GH pulses. The DAC version extends the half-life to ~8 days, creating sustained elevated GH levels.
Reconstitution Guide
Follow these steps to properly reconstitute CJC-1295 for research use:
- Step 1: Swab the tops of both the peptide vial and bacteriostatic water vial with alcohol.
- Step 2: Draw your desired amount of BAC water (commonly 1–2 mL) into an insulin syringe.
- Step 3: Inject the water slowly into the peptide vial, aiming at the glass wall — not directly onto the powder.
- Step 4: Swirl the vial gently until fully dissolved — never shake.
- Step 5: Refrigerate at 36–46°F (2–8°C). Use within 4–6 weeks.
Use the dosing calculator to calculate your exact concentration (mcg per unit) and how many units to draw on your syringe.
Frequently Asked Questions
How does CJC-1295 work? ▾
CJC-1295 is a 30-amino acid peptide analog of GHRH (growth hormone-releasing hormone) that binds to GHRH receptors on the pituitary gland, stimulating GH production. The no-DAC version (also called Mod GRF 1-29) has a half-life of about 30 minutes, producing natural GH pulses. The DAC version extends the half-life to ~8 days, creating sustained elevated GH levels.
What are the key research findings? ▾
- Increases GH and IGF-1 levels significantly while maintaining pulsatile release (no DAC)
- Improved lean body mass, fat reduction, and recovery in research
- Synergistic GH release when combined with Ipamorelin (GHRP)
- Promotes deeper sleep, enhanced recovery, and improved skin quality
What is the typical dosing protocol? ▾
No DAC: 100–300 mcg subcutaneously 1–2 times daily (morning and before bed). Often combined with Ipamorelin at the same dose for enhanced effect. With DAC: 2 mg once or twice per week. Cycles run 8–12 weeks with periodic blood work to monitor IGF-1.
How should CJC-1295 be stored? ▾
Unreconstituted powder should be stored in a freezer or refrigerator away from light and moisture. Once reconstituted with bacteriostatic water, refrigerate at 36–46°F (2–8°C) and use within 4–6 weeks. Never freeze reconstituted peptides.
