Shared Safety Flags

2x 2 compounds raise blood pressure (LGD-4033, MK-677). Monitor BP daily and consider cardiovascular support.
2x 2 compounds share the carcinogenic-risk safety flag (LGD-4033, MK-677). Monitor accordingly.
2x 2 hepatotoxic compounds (LGD-4033, MK-677). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 compounds share the teratogenic safety flag (LGD-4033, MK-677). Monitor accordingly.

LGD-4033 + MK-677
Synergistic

MK-677 (Ibutamoren) is one of the most common compounds stacked with LGD-4033. MK-677 increases growth hormone and IGF-1 through ghrelin receptor agonism, complementing the AR-mediated anabolic effects of LGD-4033. The combination may enhance lean mass accrual, recovery, sleep quality, and joint health. MK-677 does not suppress testosterone, making it a useful adjunct during and after SARM cycles. Note that MK-677 can increase appetite and water retention independently.
