Is there any side effect to take plant viagra (sildenafil) tablet I am 22 years old.

Ingredients. There is, in reality, no equivalent of viagra (sildenafil) in the plant world. That being said, there is no way to answer your question without the specific ingredients of this 'product'. But, i would caution any young man from taking these products unnecessarily. There should be absolutely no reason for a young man to need viagra (sildenafil) without a significant reason.
