Sildenafil has the same active ingredient as Viagra®, it is just as effective and at a fraction of the cost. Generic Viagra is more of an immediate solution. It is best to be taken about an hour before having sex on an empty stomach. So it’s obviously ideal if you know when you’ll be having sex. 

This is the best choice if you don’t want to take a pill every day.  It is only taken as needed

Sildenafil VS Tadalafil:
Sildenafil takes effect in about 30-45 minutes which is best for when you want to perform right away. Sildenafil does not last near as long as Tadalafil, but it has more of a ‘peak’ effect giving you its’ full strength for about 4 hours. 

Tadalafil has the same active ingredient as Cialis®, it is just as effective and at a fraction of the cost. If you’re the kind of person that has sex randomly and you can’t really predict when it will happen, Tadalafil is a good option for you.  There are two different options:

• Generic Cialis 20mg:  Generic Cialis works 1-2 hours after taking the medication. It is taken ‘only as needed’ and provides the longest results (up to 36 hours).  It has been referred to as ‘The Weekender’ for this very reason.
• Generic Cialis Daily 5mg:  Taken once a day in a low dosage.  Never have to plan sex again because your body is ready for sex at any time.  Generic Daily Cialis® offers spontaneity and flexibility.

Tadalafil VS Sildenafil:
Tadalafil has more of a ‘time-released’ effect that lasts longer or is always working if you prefer the Daily.  Sildenafil lasts about 4 hours and has more of a ‘peak effect’.
