Protecvital Plus With enlargement pills, the only thing I saw a difference in was having harder erections. And this is pretty much accurate since the only thing pills do is help slightly increase blood flow! They DO NOT increase the size of the penis. The chambers, ligaments, and muscle of the manhood must all be stimulated in order to grow a larger penis size... not just increasing blood flow. I just wish I knew that in the beginning... otherwise I wouldn't have wasted a TON of money on those expensive pills!These pills are a great way to better your performance. They also come with the common side effect of penis growth. Make sure to check the ingredients when you buy a new product. It does not have to contain all of these items, but it should at least contain some of them.
