CJC-1295 Ipamorelin is a combination of two synthetic peptides commonly used for research purposes or for anti-aging and muscle-building applications. The following is a comprehensive overview based on publicly available information: Basic Properties and Mechanism of Action CJC-1295 is a synthetic growth hormone-releasing hormone (GHRH) analog that promotes the secretion of endogenous growth hormone (GH) by activating GHRH receptors in the pituitary gland. It exists in two main forms: CJC-1295 DAC: Contains a drug-affinity complex (DAC) with a half-life of 6–8 days, making it suitable for long-term, steady-state stimulation. CJC-1295 (without DAC): With a half-life of only 30–60 minutes, it is suitable for short-term, pulsed stimulation. Ipamorelin Belongs to the growth hormone-releasing peptide (GHRP) class. It selectively acts on pituitary ghrelin receptors to stimulate GH secretion, but has minimal effects on cortisol, prolactin, and other hormones. It has a short half-life (approximately 2–4 hours) and requires multiple daily doses. Synergistic Effects Combining the two can synergistically enhance GH secretion, with effects far exceeding those of either agent alone (some data suggest up to 5 times greater). Combined use enables a smoother, more sustained release of GH, reducing the risk of side effects. Potential Benefits (Based on Research and User Reports) Increases lean muscle mass and strength Promotes fat metabolism and improves body composition Accelerates post-workout recovery Improves sleep quality, energy levels, and mood Anti-aging effects: such as increased bone density, skin elasticity, and immune function
