Reliable, on-demand, both mechanisms covered.
ED isn't one thing. For some men it's blood flow (Tadalafil, Sildenafil solve this). For others it's desire — and Viagra-class drugs don't touch that.
Performance Oral pairs both PDE5 inhibitors — daily Tadalafil for a steady baseline plus Sildenafil PRN for stronger on-demand response. Performance Injection adds PT-141, a melanocortin agonist that targets libido through the central nervous system.
Two paths. Your doctor helps you choose based on your assessment.
