CJC-1295 Sustained GH Elevation Complete Guide 2026: Comparison Table
Before selecting a GHRH analog, researchers must understand how DAC modification, dosing frequency, and physiological impact differ across peptides. The table below compares CJC-1295 with DAC to its most common alternatives. | Peptide | Half-Life | Dosing Freq

- Before selecting a GHRH analog, researchers must understand how DAC modification, dosing frequency, and physiological impact differ across peptides. The table below compares CJC-1295 with DAC to its most common alternatives.
- | Peptide | Half-Life | Dosing Frequency | GH Pulse Preservation | IGF-1 Elevation Duration | Primary Research Use | Bottom Line ||—|—|—|—|—|—|| CJC-1295 with DAC | 6–8 days | Once weekly | Yes. Maintains circadian rhythm | 7–14 days | Long-term GH modulation studies, aging research, body composition trials | Best for sustained, physiological GH elevation with minimal dosing burden || CJC-1295 no DAC (Mod GRF 1-29) | 30 minutes | 2–3× daily | Yes. Requires repeated dosing | Returns to baseline within 24 hours | Acute GH response studies, pulsatile secretion research | Requires frequent dosing but avoids albumin binding variability || Sermorelin | <10 minutes | 2–3× daily | Yes. Mimics endogenous GHRH | Returns to baseline within 12–24 hours | Pediatric GH deficiency studies, short-term protocols | Shortest half-life, highest dosing frequency, lowest convenience || Synthetic HGH (somatropin) | 2–4 hours | Daily subcutaneous | No. Suppresses endogenous pulsatility | Sustained with daily
