Dual GH Secretagogue Blend

Two Pathways, One Goal: Synergistic Growth Hormone Research

This blend combines CJC-1295 (No DAC) and Ipamorelin — two peptides that stimulate growth hormone release through distinct but complementary mechanisms. CJC-1295 acts on GHRH receptors while Ipamorelin targets the ghrelin/GHS receptor. Together, they produce synergistic effects that exceed either peptide alone, making this blend essential for comprehensive GH axis research.

  • 10mg total: CJC-1295 (5mg) + Ipamorelin (5mg)
  • Dual-pathway GH stimulation (GHRH + Ghrelin receptors)
  • Synergistic effects when combined
  • Preserves natural pulsatile GH secretion patterns
  • No DAC formulation for controlled research protocols
Complementary Mechanisms

How Two Peptides Amplify Growth Hormone Release

CJC-1295 stimulates GH release by binding to GHRH receptors on the pituitary — the same pathway used by the body's natural growth hormone-releasing hormone. Ipamorelin works through a completely different mechanism: it's a potent agonist of the ghrelin/GHS receptor, one of the most selective GH secretagogues known. This dual-receptor approach raises both baseline GH levels and peak secretion while maintaining natural pulsatile patterns.

  • CJC-1295: GHRH receptor agonist (pituitary stimulation)
  • Ipamorelin: Ghrelin/GHS receptor agonist (highly selective)
  • Raises baseline GH levels (Ipamorelin effect)
  • Produces higher peaks and troughs (CJC-1295 effect)
  • Maintains natural pulsatile secretion pattern
Research Applications

From Bone Health to Metabolic Function — Comprehensive GH Research

The CJC-1295/Ipamorelin combination enables research across the full spectrum of GH-mediated effects. Ipamorelin alone has demonstrated benefits for bone health, muscle development, insulin release, and gastric function in animal models. Combined with CJC-1295's ability to normalize growth in GHRH-deficient models, this blend provides a comprehensive platform for GH axis research.

  • Bone health and mineral density research
  • Muscle repair and development studies
  • Insulin secretion and metabolic function
  • Bowel motility and gastric function research
  • Body composition and lean mass studies
  • GH axis dysfunction and restoration modeling
