Shared Safety Flags

2x 2 androgenic compounds (RAD-140, YK-11). Additive androgenic load — increased risk of hair loss, acne, prostate effects.
2x 2 compounds raise blood pressure (RAD-140, YK-11). Monitor BP daily and consider cardiovascular support.
2x 2 compounds share the carcinogenic-risk safety flag (RAD-140, YK-11). Monitor accordingly.
2x 2 hepatotoxic compounds (RAD-140, YK-11). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 HPTA-suppressive compounds (RAD-140, YK-11). Deep hormonal shutdown expected — plan extended PCT.
2x 2 compounds disrupt lipids (RAD-140, YK-11). Get lipid panel mid-cycle — consider adding lipid support.

RAD-140 + YK-11
Monitor

YK-11 and RAD-140 are sometimes stacked by users seeking to combine YK-11's myostatin inhibition with RAD-140's potent AR agonism. This combination compounds the risk of testosterone suppression and liver enzyme elevation, as both compounds are hepatically metabolized. If combining, comprehensive blood work (liver function, hormones, lipids) is essential at baseline, mid-cycle, and post-cycle. Liver support supplementation is strongly recommended.
