I took regular vigrx pills many many years so. Review wise it really depends what your after, they helped with increasing erection quality some what but these pills will never really directly increase size as such, they may help as an aid with Penis Enlargement routine. If you are interested by them I would recommend looking at the MOSTitan Pills, from what I gather its pretty much the same ingredients but I fraction of the price.
There is really no difference in the formula but inactive ingredients. If you take a supplement my advices to go with MaleExtra or TITAN, both are on special and both contain everything you need to supplement your gains. Both links I posted bring you to the 25% off deals. Save money and get the best supplements.
