Nebivolol
Third-generation beta-blocker with high beta-1 selectivity and additional nitric oxide (NO) potentiation via stimulation of endothelial NO synthase. The NO-mediated vasodilation distinguishes it from older beta-blockers that worsen peripheral vascular resistance. Does not impair glucose metabolism or lipid profiles at therapeutic doses, unlike non-selective beta-blockers.

Nebivolol breaks every rule that made beta-blockers undesirable for active people. Traditional beta-blockers reduce exercise capacity, impair fat metabolism, worsen insulin sensitivity, and cause fatigue. Nebivolol does none of those things at standard doses because its NO-potentiating mechanism offsets the peripheral vasoconstriction that older beta-blockers produce. You get heart rate control without metabolic penalty. For someone on TRT who develops elevated resting heart rate or blood pressure — a common and undertreated issue — nebivolol is the beta-blocker that does not undo the metabolic benefits of hormone optimization. The CYP2D6 polymorphism creates a tenfold bioavailability range between extensive and poor metabolizers. Dose to heart rate response, not to label.
