CJC-1295 with DAC vs. CJC-1295 (No DAC)
| Attribute | CJC-1295 with DAC | CJC-1295 (No DAC) |
|---|---|---|
| DAC Modification | Drug Affinity Complex (DAC) attached | No DAC - plain modified GHRH |
| Half-Life | 5.8–8.1 days (once or twice weekly) | ~30 minutes (1–3× daily required) |
| GH Pattern | Sustained non-pulsatile bleed | Sharp, natural-mimicking pulses |
| Stacking | Typically used solo or with GHRP | Best paired with Ipamorelin (gold standard) |
| Convenience | Maximum - 1–2×/week dosing | Requires 1–3 daily injections |
| IGF-1 Concerns | Higher IGF-1 elevation (sustained) | More physiological IGF-1 profile |
Verdict: CJC-1295 DAC wins for convenience (twice-weekly dosing); CJC-1295 No DAC wins for physiological GH pulse preservation. The No DAC + Ipamorelin stack is preferred by most protocols for mimicking natural GH rhythms and avoiding chronically elevated IGF-1.
