I looked at the formula of Vig-RX, and it does have some things in it which are known to work.

Muria Puama, known as \"potency wood\" is a traditional aphrodesiac (more info here ), and Epimedium Saggittum is a traditional chinese remedy known as Yin Yang Huo, used for treating \'kidney yang deficiency\', ie: lack of male power (more info here ).

So they are trying to come up with a good formulation.

I don\'t know about length increases, but it could very well provide erection improvements. The ingredients are available at a lower cost elsewhere, should you want to look for them.
