CJC-1295: Growth Hormone Research and Applications

Peptide Profiles — 2026-04-11

CJC-1295 is a synthetic analog of growth hormone releasing hormone (GHRH) that has been extensively studied for its ability to increase growth hormone (GH) secretion. Available in two forms — with and without Drug Affinity Complex (DAC) — each version offers distinct pharmacokinetic properties for different research applications.

CJC-1295 with DAC

The DAC modification extends the half-life dramatically by binding to albumin in the bloodstream.

Properties - Half-life: ~6-8 days - Provides sustained, elevated GH levels - Single administration can elevate GH for up to a week - Results in a "blunted" pulsatile GH pattern

Research Applications - Long-term body composition studies - Sustained GH elevation protocols - Growth factor research requiring stable GH levels

CJC-1295 without DAC (Modified GRF 1-29)

Without the DAC modification, this peptide more closely mimics natural GHRH signaling.

Properties - Half-life: ~30 minutes - Preserves natural pulsatile GH release pattern - More physiological GH elevation - Often studied in combination with GHRPs

Research Applications - Pulsatile GH research - Combination studies with ipamorelin or other GHRPs - Research requiring more natural GH release patterns

CJC-1295 + Ipamorelin: The Research Combination

One of the most studied peptide combinations is CJC-1295 (no DAC) with ipamorelin. The rationale: - CJC-1295 stimulates the GHRH pathway (amplifies the signal) - Ipamorelin stimulates the ghrelin/GHSR pathway (initiates the pulse) - Together, they produce a synergistic increase in GH release

Growth Hormone Research Context

Growth hormone plays a central role in: - Body composition regulation - Bone density maintenance - Metabolic health - Recovery and tissue repair - Sleep quality and patterns

Understanding GH secretagogues like CJC-1295 is essential for researchers studying these interconnected systems.
