Viagra 101
The science
Generic Viagra (sildenafil) works by improving blood flow to the penis, helping you achieve and maintain a stronger erection for longer.
Taking Viagra
Viagra begins to work in as little as 30 minutes and remains effective for up to 4–6 hours. It doesn’t cause arousal, so an erection only occurs when you are sexually stimulated.
Strengths
It comes in three strengths: 25mg, 50mg, and 100mg. Most people start with 50mg if they are new to Viagra.
Pay 95% less
Generic Viagra is much more affordable than the branded version, yet it contains the same active ingredient and is equally effective in treating ED.
