- Plasma Half-Life
- ~30 minutes
- 6–8 days
- No DAC requires multiple daily doses; DAC allows weekly administration
- Time to Peak (Tmax)
- 5–15 minutes
- 1–4 hours
- No DAC produces rapid GH pulse; DAC produces gradual elevation
- GH Release Pattern
- Discrete pulses (2.5–4× baseline)
- Sustained low-level elevation (1.5–2× baseline)
- No DAC mimics physiological secretion; DAC produces non-pulsatile profile
- Receptor Occupancy Duration
- <60 minutes
- Continuous (days)
- No DAC avoids desensitisation; DAC may reduce pulse amplitude over time
- Clearance Mechanism
- Renal filtration + enzymatic degradation
- Albumin binding delays both pathways
- No DAC cleared within 90 minutes; DAC persists for days
- Professional Assessment
- Preferred for pulsatile GH protocols and combination with GHRPs; matches endogenous secretory rhythm
- Preferred for sustained GH elevation without daily dosing; may reduce responsiveness to endogenous GHRH
