MK-677 and RAD-140 Interaction

Synergistic
Researched 95% confidence

MK-677 and RAD-140 have a synergistic interaction with 95% confidence. MK-677 (Ibutamoren) is frequently stacked with RAD-140. MK-677 increases growth hormone and IGF-1 through ghrelin receptor agonism, complementing the AR-mediated anabolic effects of RAD-140. The combination may enhance lean mass accrual, recovery, and sleep quality. MK-677 does not suppress testosterone, making it a useful adjunct during and after SARM cycles. These compounds primarily affect different organ systems.

Compound Profiles

MK-677

Ghrelin Receptor Agonist | Oral Growth Hormone Secretagogue

Selectively binds GHS-R1a receptors in hypothalamus and pituitary, triggering pulsatile growth hormone release while maintaining natural circadian patterns..

RAD-140

Selective Androgen Receptor Modulator | Investigational SARM

RAD-140 binds to the androgen receptor (AR) with high affinity and selectivity, functioning as a full agonist in muscle and bone tissue while exhibiting minimal agonist activity in the prostate and other androgen-sensitive tissues. This tissue selectivity is achieved through differential cofactor recruitment: upon binding to the AR, RAD-140 induces a conformational change that favors interaction with coactivators predominantly expressed in skeletal muscle and bone, rather than those prevalent in prostate or sebaceous glands.

Shared Safety Flags

2x 2 compounds raise blood pressure (MK-677, RAD-140). Monitor BP daily and consider cardiovascular support.
2x 2 compounds share the carcinogenic-risk safety flag (MK-677, RAD-140). Monitor accordingly.
2x 2 hepatotoxic compounds (MK-677, RAD-140). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
