What is CJC-1295 & Hexarelin Blend?

Tap any underlined term for an instant definition.

CJC-1295 & Hexarelin Blend combines CJC-1295 (no DAC) with hexarelin, the most potent in the GHS family. Hexarelin produces the highest GH pulse amplitudes of any but has a faster desensitization profile, requiring cycling to maintain efficacy.

What It Is

  • CJC-1295 (no DAC): analogue for pulsatile GHRHR activation
  • Hexarelin: the most potent , producing GH pulses that exceed GHRP-2 and GHRP-6 at equivalent doses; also has documented cardiac cytoprotective effects independent of GH receptor
  • High-potency combination for maximum GH axis stimulation

How It Works

  • Standard + dual-receptor synergy
  • Hexarelin's GHS-R1a potency produces the largest GH pulses of any combination at equivalent doses
  • Hexarelin also binds the CD36 scavenger receptor, mediating cardiovascular effects that are GH-receptor independent
  • Desensitization: hexarelin downregulates its own receptor faster than other GHRPs; use in cycles of 4-6 weeks with 2-4 week breaks

Key Research Findings

  • GH amplitude: Highest of any at equivalent doses; GH peaks up to 80-100 ng/mL reported in some studies
  • Cardiac cytoprotection: Hexarelin reduced infarct size by 30-40% in MI models independent of GH receptor
  • Desensitization: Significant GH response reduction after 2-4 weeks of continuous daily use; cycling mandatory

Dosing From the Literature

  • CJC-1295 (no DAC) 100-200 mcg + hexarelin 50-100 mcg per injection
  • Lower hexarelin doses (50 mcg) reduce cortisol/prolactin side effects while retaining synergistic GH benefit
  • Cycle hexarelin 4-6 weeks on, 2-4 weeks off

Storage and Handling

  • Lyophilised: 2-8 degrees C; 24 months
  • : 2-8 degrees C; use within 30 days
