What is CJC-1295 & Ipamorelin Blend?

Tap any underlined term for an instant definition.

CJC-1295 & Ipamorelin Blend refers to the combination of CJC-1295 without DAC (identical to Mod GRF 1-29) with ipamorelin. This is the same combination discussed as "Mod GRF 1-29 + Ipamorelin" in the research literature, formulated under the more commercially recognizable CJC-1295 naming convention.

What It Is

  • CJC-1295 (no DAC) = Mod GRF 1-29: the 4-substitution analogue without Drug Affinity Complex modification
  • Ipamorelin: highly selective GHS-R1a agonist
  • Identical mechanism and expected outcomes to Mod GRF 1-29 + Ipamorelin blend
  • Note: distinct from CJC-1295 with DAC, which has 6-8 day and produces sustained rather than pulsatile GH elevation

How It Works

  • CJC-1295 (no DAC) provides GHRHR stimulation with ~30-60 minute
  • Ipamorelin provides complementary GHS-R1a stimulation and somatostatin suppression
  • Synergistic GH pulses of 3-4x either peptide alone
  • Physiological pulsatile GH pattern preserved

Key Research Findings

  • Same evidence base as Mod GRF 1-29 + Ipamorelin
  • Most widely used GH-stimulating peptide combination in the research community
  • Strong safety profile from multiple long-term monitoring studies

Dosing From the Literature

  • CJC-1295 (no DAC) 100-200 mcg + Ipamorelin 200-300 mcg per injection
  • Twice daily on empty stomach

Storage and Handling

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