While MK-677 doesn't directly stimulate hypertrophy like testosterone or trenbolone, it promotes muscle growth by: Increasing IGF-1 levels (which drive satellite cell activation and muscle fiber repair) Enhancing protein synthesis and nitrogen retention Supporting improved recovery, allowing for more frequent/intense training Improving deep sleep, which boosts growth hormone pulses and recovery overnight In a well-known 12-month study, MK-677 increased fat-free mass by 2.88 kg in elderly subjects without altering exercise or diet
