Shared Safety Flags

2x 2 hepatotoxic compounds (Finasteride, Proviron). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 compounds share the teratogenic safety flag (Finasteride, Proviron). Monitor accordingly.

Finasteride + Proviron
Avoid

Finasteride blocks the conversion of testosterone to DHT via 5-alpha reductase inhibition. Proviron is a DHT derivative whose effects depend on direct androgenic receptor activation as a DHT analogue. While finasteride does not directly deactivate Proviron, the combination is pharmacologically contradictory — one compound is a DHT agonist and the other suppresses DHT production. Concurrent use undermines the rationale for using either compound and may produce unpredictable androgenic signaling.
