CJC-1295: Dosage & Administration

CJC-1295 exists in two distinct forms with very different dosing protocols:

Form	Dose	Frequency	Timing
CJC-1295 with DAC	1–2 mg	Once weekly	Any time (long half-life)
CJC-1295 no DAC (Mod GRF 1-29)	100–200 mcg	2–3× daily	Fasted — bedtime primary, post-exercise optional

The non-DAC form is more commonly used in research because it preserves the body's natural pulsatile GH release pattern. It is almost always paired with a GHRP (growth hormone releasing peptide) such as ipamorelin for synergistic GH release.

CJC-1295 + Ipamorelin stack: 100 mcg CJC-1295 no DAC + 200 mcg ipamorelin, administered together subcutaneously 2–3× daily (before bed and optionally post-exercise).

CJC-1295 typically comes in 2mg or 5mg lyophilized vials:

• 2mg vial + 2mL BAC water = 1mg/mL (1,000 mcg/mL) — draw 0.1mL for 100 mcg (Mod GRF dosing)
• 5mg vial + 2mL BAC water = 2.5mg/mL — draw 0.4mL for 1mg (DAC dosing)

Use the peptide calculator for precise volumes. See the reconstitution guide for preparation.

Timing is critical for CJC-1295, especially the non-DAC form:

• Fasting required: Administer at least 2 hours after eating. Food (especially carbohydrates) blunts the GH release response
• Bedtime dose: The most important dose, as it amplifies the natural nocturnal GH pulse
• Post-exercise dose: Optional second dose to capitalize on exercise-induced GH release
• Morning dose: Optional third dose upon waking (still fasted)
• Cycle length: 8–12 weeks, with some protocols running up to 16 weeks
• Off period: 4–8 weeks between cycles is commonly used to prevent GH receptor desensitization

Standard peptide storage:

• Lyophilized: -20°C long-term, 2–8°C for months
• Reconstituted: Refrigerate at 2–8°C, use within 28 days
• CJC-1295 is relatively stable in reconstituted form
