Cialis vs viagra

What is stronger, 20 mg cialis or 100 mg viagra? What will make better erection?

Try both see which works better for you.

Viagra start to work on me after 5-10 minutes. And make me fell a lot better even week after.
And i never tried cialis.

Viagra has a shorter half life (a few hours). Cialis has a longer half life, the effects can last a 1-3 days I believe.

Sometime viagra work on me more than 12 hr.
But what will make stronger erection? And what will happen if i add also l arginine?

I recommend using Cialis 2.5 mg, once a day.

What’s a good website to order these from online that delivers legitimate product?
