Shared Safety Flags

2x 2 estrogenic compounds (Finasteride, Testosterone). Combined estrogen elevation — monitor E2 and consider aromatase inhibitor.
2x 2 hepatotoxic compounds (Finasteride, Testosterone). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 compounds share the teratogenic safety flag (Finasteride, Testosterone). Monitor accordingly.
