Duration Is Not One Number
Sildenafil and tadalafil have different duration profiles as finished drugs. A compounded combination does not automatically inherit a single tidy window. Alcohol, food, dose, and individual response still dominate. Ask your clinician what to expect for your prescription rather than relying on a marketing onset claim alone.
