- Half-Life
- 30 minutes plasma; 2–4 hours effective
- 6–8 days terminal half-life
- DAC variant extends circulation 200-fold, suitable for sustained-release protocols
- GH Secretion Pattern
- Pulsatile. Amplifies natural ultradian rhythm
- Tonic. Continuous elevation independent of circadian gating
- Standard CJC-1295 preserves physiological feedback; DAC variant bypasses it
- Dosing Frequency
- 1–3 times daily for sustained effect
- Once every 5–7 days
- Standard variant requires more frequent handling but allows tighter temporal control
- Receptor Dynamics
- Acute stimulation with inter-dose recovery
- Chronic stimulation without recovery period
- Chronic exposure may downregulate pituitary GH-releasing hormone receptors over time
- Experimental Fit
- Acute response studies, circadian research, dose titration protocols
- Long-duration metabolic studies, steady-state GH models
- Choose based on whether pulsatility is a variable or a confound in your design
- Serum Stability
- Rapidly degraded without DPP-IV protection
- Albumin binding protects from enzymatic degradation
- Both have enhanced DPP-IV resistance vs native GHRH; DAC adds albumin shield
