CJC-1295 (with DAC)
Also known as CJC-1295 DAC, Drug Affinity Complex CJC-1295
CJC-1295 with DAC is a long-acting GHRH analog where a Drug Affinity Complex extends its half-life to ~8 days by binding to albumin. This creates a GH 'bleed' effect rather than natural pulsatile release — preferred by some advanced users but more suppressive.
How it works
Same GHRH receptor activation as Mod GRF 1-29 but with DAC technology that binds to serum albumin, dramatically extending half-life to ~8 days. Creates continuous GH elevation.
Benefits
- Sustained GH elevation over several days per injection
- Convenient once or twice weekly dosing
- Significant IGF-1 increases
- Muscle mass and fat loss over longer cycles
Dosing
1000–2000 mcg · 1–2x per week
DAC creates a GH 'bleed' — some users prefer pulsatile Mod GRF instead. Combine with GHRP optional but less critical.

Who it’s for
Experienced users comfortable with GH peptides who prefer infrequent dosing. Not recommended as a first GH peptide due to non-pulsatile GH release pattern.
