Mechanism of Action Binds to ghrelin receptors (GHSR1a) in the hypothalamus Stimulates the pituitary gland to release growth hormone Increases circulating levels of IGF1 , a powerful anabolic hormone Enhances deep sleep stages and GH pulsatility over time Works systemically with no injection required MK677 increases serum GH and IGF1 levels to those seen in young adults, supporting muscle growth and improved body composition. Smith et al., The Journal of Clinical Endocrinology & Metabolism Applications Muscle preservation and hypertrophy Improved sleep, recovery, and GH output Long-term fat loss and recomposition Off-cycle muscle retention Age-related GH decline or recovery support Delivery Taken orally (1025 mg/day) Long half-life (~24 hours) allows once-daily dosing Typically cycled for 812 weeks , or used continuously at low doses CJC1295 Overview and How It Works CJC1295 is a synthetic growth hormone-releasing hormone (GHRH) analog that stimulates the pituitary gland to increase natural growth hormone (GH) secretion
