- CJC-1295 No DAC
- GHRH receptor (anterior pituitary)
- Gs → adenylyl cyclase → cAMP → PKA → calcium influx
- ~30 minutes
- Amplifies magnitude of endogenous pulses; preserves circadian rhythm
- Increased GH pulse amplitude without desensitization
- Ideal for maintaining physiological pulse structure while increasing peak GH output; No DAC variant prevents receptor downregulation
- Ipamorelin
- GHS-R1a (ghrelin receptor)
- Gq → phospholipase C → IP3/DAG → calcium release + PKC activation
- ~2 hours
- Increases pulse frequency and duration; mimics post-exercise GH spike
- Enhanced GH pulse frequency and peak sharpness
- Highly selective secretagogue with minimal off-target effects; pairs mechanistically with GHRH analogs for synergistic effect
- Combined Protocol
- Dual-receptor (GHRH + ghrelin)
- Parallel Gs and Gq activation → synchronized calcium mobilization
- Sequential dosing window
- Synchronized high-amplitude, high-frequency GH pulses
- 3–4× baseline GH output; 80–90% elevation in IGF-1 over 8 weeks
- Mechanistic synergy through complementary pathways; avoids receptor competition and preserves feedback loops that single-pathway protocols disrupt
