- Design
- Albumin-binding via DAC → long-acting GHRH analog
- Short-acting GHRH(1-29) analog without albumin binding
- Half-life / Exposure
- Prolonged exposure (days) with sustained GH/IGF-1 rise in humans1
- Minutes; brief spikes in plasma → transient GH pulses
- GH Secretion Pattern
- Elevates basal GH and augments pulses, trending toward a more tonic profile under continuous exposure1
- Primarily pulsatile bursts when dosed intermittently, aligning with physiologic ultradian GH rhythms2
- Physiologic Relevance
- Useful for sustained stimulation; may blunt relative pulse amplitude depending on background somatostatin tone
- Better preserves timing-dependent physiology and receptor recovery windows described for normal GH neuroendocrine control2
- Downstream Readouts
- Clear increases in circulating IGF-1 over days to weeks in early clinical studies1
- Short-window GH/IGF-1 excursions; magnitude depends on dose timing and co-secretagogues
