Potential Benefits for Workouts: Increased Blood Flow and Muscle Pumps: Tadalafil is a PDE5 inhibitor, meaning it increases blood flow to the penis by relaxing blood vessels. This same mechanism could improve blood flow to working muscles during workouts, leading to enhanced nutrient delivery and a more noticeable "muscle pump". Improved Endurance and Performance: Enhanced blood flow can deliver more oxygen and nutrients to the muscles, potentially delaying fatigue and improving workout performance, Faster Recovery: Improved circulation can aid in the removal of metabolic waste products from muscles, potentially accelerating recovery and reducing muscle soreness. Potential Cognitive Benefits: Some suggest improved blood flow to the brain might enhance mental focus and clarity during exercise.
