CJC-1295 Without DAC — Modified GHRH Analog for Pulsatile GH Research
CJC-1295 Without DAC (Mod GRF 1-29) is a synthetic 29-amino acid GHRH analog with four substitutions (Ala2, Gln8, Ala15, Leu27) conferring DPP-IV resistance. Unlike the DAC version, it preserves natural pulsatile GH release, making it preferred for physiological GH secretion research.
Mechanism of Action
CJC-1295 Without DAC binds GHRH receptors on pituitary somatotrophs, activating the Gs-adenylyl cyclase-cAMP-PKA cascade for GH vesicle exocytosis. Half-life extended from ~7 min (native GRF 1-29) to 30+ min while maintaining pulsatile release kinetics essential for avoiding GH receptor desensitization.
Key Research Areas
- Pulsatile GH Secretion: Stimulates somatotrophs without sustained elevation, preserving the ultradian rhythm of GH secretion.
- Synergistic Secretagogue Research: Frequently combined with Ipamorelin — complementary GHRH + GHS-R pathways amplify GH release synergistically.
- Somatotroph Cell Biology: Tool for investigating GHRH receptor signaling, cAMP response, and GH gene transcription.
- DPP-IV Resistance Engineering: Model for studying how strategic amino acid substitutions extend peptide bioavailability.
