I'm taking extagen for about 4 months. Only I can say: GUYS, IT WORKS!! Hard erection and increased stamina not only effect of these pills. I've gained 3.7 cm in length and almost 2 cm in girth. I also contacted extagen support here
www.extagensolution.com/contact.php, they claims extagen results are permanent.
PS. I got this purple miracle from eBay, 6 month supply for only $139.95 + $10.95 for extremely fast shipping. There are one guy selling extagen in bottles, beware it's fake! Original pills only in boxes, here is a link for original extagen
ebay. Just give extagen a chance..
