CJC 1295 (without DAC)

What is CJC-1295 (Without DAC)?

CJC-1295 (Without DAC), also known as Modified GRF (1-29) or Sermorelin Tetrasubstituted, is a synthetic peptide consisting of 29 amino acids. It functions as a potent Growth Hormone-Releasing Hormone (GHRH) analogue. This version is specifically engineered without the Drug Affinity Complex (DAC), meaning it lacks the attachment that binds to blood proteins to artificially prolong its life cycle. Instead, CJC-1295 (Without DAC) mimics the natural, pulsatile physiological release of Growth Hormone (GH) from the pituitary gland, allowing researchers to study precise, time-sensitive cellular signaling and metabolic mechanisms.

Key Research Benefits & Mechanisms

• Simulates Natural Pulsatile Release: Because it lacks the DAC modification, it triggers brief, natural "spikes" of Growth Hormone, avoiding pituitary fatigue or receptor down-regulation.
• Accelerates Lean Muscle Development: Stimulates deep cellular pathways that enhance protein synthesis, assisting in preclinical research focused on hyperplastic muscle growth and improved body composition.
• Promotes Rapid Fat Loss (Lipolysis): Activates specific hormone-sensitive receptors that force fat cells to release stored fatty acids, accelerating lipid breakdown in experimental models.
• Triggers Controlled IGF-1 Production: Signals the liver to release a steady, safe supply of Insulin-Like Growth Factor 1 (IGF-1), which drives cell repair, tissue healing, and systemic recovery.
• Enhances Deep Tissue Repair: Accelerates the regeneration of bones, connective tissues, and muscles following localized cellular injury or oxidative stress.
• Optimizes Sleep Architecture Models: Research indicates that GHRH secretagogues dramatically support slow-wave deep sleep cycles, a crucial phase for biological cellular repair.
