- CJC-1295 No DAC
- GHRH receptor (pituitary somatotroph)
- cAMP → PKA → CREB phosphorylation
- Upregulates GH1 gene transcription by 40–60% via CRE binding
- 6–8 hours post-dose
- Growth hormone (GH)
- Best for sustained baseline elevation of GH synthesis. Preserves pulsatility, minimizes receptor desensitization
- Ipamorelin
- GHSR1a (ghrelin receptor)
- Calcium influx → GH granule exocytosis
- Indirectly increases IGF-1 gene transcription via JAK2-STAT5 activation in liver
- 8–12 hours post-dose
- Insulin-like growth factor-1 (IGF-1)
- Best for amplifying pulsatile GH release without cortisol/prolactin cross-activation. Highly selective
- CJC-1295 + Ipamorelin (combined)
- GHRH receptor + GHSR1a (dual pathway)
- cAMP + calcium-mediated dual activation
- Compounds transcriptional activation. GH1 upregulation + hepatic IGF-1 mRNA increase of 85%
- 8–12 hours (synergistic peak)
- GH + IGF-1 (amplified cascade)
- Dual-pathway synergy delivers transcriptional effects neither peptide achieves alone. Ideal for research models requiring sustained anabolic signaling
