CJC-1295 DAC (2mg) + Ipamorelin Stack

Components: CJC-1295 DAC + Ipamorelin

A GH secretagogue stack combining CJC-1295 DAC (2mg vial, once weekly) and Ipamorelin (5mg vial, once daily). DAC provides sustained GHRH stimulation while Ipamorelin delivers daily selective GH pulses.

Stack Components

This stack uses 2 separate vials — each peptide is reconstituted independently.

Vial Size 2mg
BAC Water 2mL
Concentration 1,000mcg/mL
Dose 1000 mcg (1 mg) once weekly

Ipamorelin

Always use bacteriostatic water to reconstitute each vial. Draw from separate vials — do not mix in the same syringe unless your protocol specifies a shared injection.

Week by Week

Protocol Timeline

Full 8–16 weeks cycle breakdown.

Weeks 1u20132 (Initiation) CJC-1295 DAC loading, low-dose Ipamorelin

CJC-1295 DAC: 1000 mcg (40 units, 0.40 mL) once weekly. Ipamorelin: 100 mcg (6 units) once daily before bed. First CJC-1295 DAC injection establishes elevated GH/IGF-1 baseline lasting approximately 6u20138 days.

Weeks 3u20134 (Titration) Continued weekly CJC, advancing Ipamorelin dose

CJC-1295 DAC: continue 1000 mcg once weekly. Ipamorelin: advance to 150 mcg (9 units) once daily. Body composition changes begin to appear u2014 improved recovery and early lean mass development.

Weeks 5u201312 (Maintenance) Full maintenance dosing

CJC-1295 DAC: continue 1000 mcg once weekly. Ipamorelin: advance to 200 mcg (12 units) once daily. Sustained GH elevation from CJC-1295 DAC combined with daily Ipamorelin pulses drives progressive body composition improvement.

Weeks 13u201316 (Optional extension) Extended cycle if well tolerated

Both peptides continue at established doses. Assess for any signs of water retention or other GH-related effects. End with a 4-week break before repeating.

Why It Works

Synergy Notes

CJC-1295 DAC's Drug Affinity Complex (DAC) moiety binds serum albumin, extending its half-life to approximately 6–8 days — providing a steady GHRH background that primes the pituitary for the entire week. Ipamorelin's daily pre-sleep administration then triggers amplified nocturnal GH pulses through the complementary ghrelin receptor pathway. The combination of sustained GHRH stimulation plus daily GHRP pulsing produces greater total GH output than either agent alone.

Results

What to Expect

Weeks 1–3: Improved sleep quality and depth. Weeks 4–8: Progressive lean mass improvement and fat reduction. Weeks 9–16: Continued body composition changes, improved skin quality and recovery. Water retention is possible in the first 2–4 weeks and typically resolves.
