- Half-life
- 6–8 days
- ~30 minutes
- DAC modification extends half-life 200–300×, enabling weekly dosing instead of multiple daily injections
- Peak GH Timing
- 8–12 hours post-injection
- 15–30 minutes post-injection
- Modified version creates sustained elevation; unmodified creates pulsatile spikes mimicking natural secretion
- Dosing Frequency
- Once weekly
- 2–3× daily
- DAC version requires far fewer injections but eliminates control over pulse timing
- GH Elevation Pattern
- Sustained platform (2–2.5× baseline for 6–8 days)
- Sharp pulse (5–10× baseline for 1–2 hours)
- Modified provides consistent elevation; unmodified allows targeted pre-sleep or pre-training pulses
- IGF-1 Response
- 45–60% increase sustained 7–14 days
- 20–30% increase lasting 12–24 hours
- DAC version produces higher cumulative IGF-1 AUC per week
- Professional Assessment
- Best for researchers prioritizing convenience and sustained anabolic signaling. Weekly dosing reduces compliance burden but removes flexibility. Steady-state IGF-1 elevation maximizes tissue remodeling over time.
- Best for protocols requiring precise pulse control or mimicking physiological GH secretion. Multiple daily dosing is labor-intensive but allows timing around training or sleep for targeted effects. Lower risk of receptor desensitization due to intermittent stimulation.
