I took extagen for about two months. They send you a paper w/ instructions and exercises to do while taking the pills, which the exercises are PEing. But I hardly did the exercises seeing if the pills worked. Only thing I saw was I was able to get a boner quicker and stay hard. Otherwise no gain in lenth and or girth
Try it yourself, they are good about giving you back their money and you can pretty much try it risk free for 90 days. Customer service is good
