Why Viagra?
Viagra (sildenafil) is an ED medication that helps improve blood flow to the penis by blocking an enzyme called PDE5. This makes it easier to get a harder erection.
Taken orally in tablet form, it starts working in just 30–60 minutes, lasting in your body for 4–6 hours. Viagra doesn’t cause arousal, so don’t worry — you’ll only get an erection when you’re feeling aroused.
Viagra is available as an unbranded tablet called sildenafil. It’s up to 80% cheaper, but has the same active ingredient and is just as effective as branded Viagra.
