CJC-1295 No DAC Dosing Protocol: 5 mg Vial — Pulsatile GHRH Dosing Guide
CJC-1295 without DAC (Modified GRF 1-29) protocol — the pulsatile GHRH analogue for 2–3x daily injection alongside GHRPs.
Quickstart highlights
CJC-1295 without DAC (also called Modified GRF 1-29 or Mod-GRF) is a 29-amino acid GHRH analogue with four amino acid substitutions (Ala8, Glu15, Ala18, Arg26) that improve receptor affinity and proteolytic stability over native GHRH while maintaining a physiological 30-minute half-life.
Concentration: 2 mg/mL (5 mg vial + 2.5 mL bacteriostatic water).
At 2 mg/mL: 200 μg = 10 units, 300 μg = 15 units per injection.
Half-life: ~30 minutes — inject simultaneously with GHRP (ipamorelin, GHRP-2) for synergistic GH release.
Can be mixed with ipamorelin or GHRP-2 in the same syringe immediately before injection.
One 5 mg vial provides ~17 doses at 300 μg — approximately 5–6 days at 3x daily.

Reconstitution steps
Draw 2.5 mL bacteriostatic water; inject slowly down the vial wall.
Swirl gently until powder dissolves; do not shake.
Final concentration: 2 mg/mL (2,000 μg/mL). At 2 mg/mL: 200 μg = 10 units, 300 μg = 15 units.
Label with date; refrigerate at 2–8 °C. Use within 28 days.

Protocol overview & cycle notes
Achieve maximal pulsatile GH secretion through the precise co-injection of CJC-1295 No DAC (GHRH) and a GHRP (ipamorelin or GHRP-2) 2–3x daily, mimicking the natural GHRH + ghrelin synergy that drives physiological GH pulses.
Cycle length: 12 weeks on.
Off-cycle: 4–6 weeks off; measure IGF-1 before resuming.
Storage & handling
Injection & tracking tips
CJC-1295 No DAC has a 30-minute half-life — timing with the GHRP injection is critical; inject within 5 minutes of each other.
Can be mixed in the same syringe as ipamorelin or GHRP-2 for a single injection — stable when mixed immediately before use; do not pre-mix and store.
Inject in fasted state (2+ hours post-meal); food-driven insulin blunts GH response to the peptide combination.
Tracking
Logging helps you and your provider spot patterns and adjust dose or timing.
Measure IGF-1 at baseline, 6 weeks, and 12 weeks.
Track sleep quality nightly (subjective 0–10 or wearable deep sleep data).
Log body fat percentage monthly via InBody or DEXA.
