The CJC-1295/Ipamorelin blend is the most-studied growth-hormone secretagogue combination. It ships lyophilized as a pre-blended vial and is reconstituted with bacteriostatic water. Because it is a blend of two peptides, the concentration math applies to the combined mass.

Key research interest

CJC-1295 / Ipamorelin is studied across several research directions. The points below summarize what the published literature investigates — they describe research interest only, not outcomes, benefits, or any human-use claim.

  • Studied for stimulated endogenous growth-hormone release
  • Researched for amplified GH pulse amplitude with minimal cortisol/prolactin rise
  • Investigated for downstream IGF-1 signaling in preclinical models
  • Examined for combined GHRH-plus-ghrelin-mimetic synergy
  • Studied for sustained GH elevation from the DAC-extended half-life

Mechanism of action

Pairs a GHRH analog (CJC-1295) that binds pituitary GHRH receptors with a selective ghrelin-receptor (GHS-R) agonist (Ipamorelin). The two pathways are studied for synergistically increasing pulsatile growth-hormone secretion while Ipamorelin’s selectivity limits cortisol and prolactin elevation.

CJC-1295 / Ipamorelin research reference

Reference figures summarized from published research literature for context only. These are not instructions, protocols, or dosing advice — CJC-1295 / Ipamorelin is a research compound for laboratory use, not for human consumption.

  • Published research range: 100–300 mcg of each component (200–600 mcg total blend), 1–3× daily (published range)
  • Administration (in research): Subcutaneous — research timing often favors pre-sleep dosing
  • Storage & handling: Refrigerate after reconstitution; used within 30 days in most research protocols.
