Compatible

Propranolol and tadalafil can be used concurrently. Beta blockers may theoretically contribute to erectile difficulties, but low-dose propranolol used for heart rate management during AAS cycles rarely causes significant erectile dysfunction. Tadalafil's PDE5 inhibition operates independently of beta-adrenergic pathways. Monitor blood pressure, as both agents lower BP through different mechanisms.
