I'm not sure how's the best way to say this but here I go, people want your money so if you want something then they want to be the ones to sell it to you even if it something you could get for free. Do you really think a study group would spend thousands of dollars plus a year or two just to find out if this stuff work so they can make no money off it. A doctor wants to sell you a $5000 penis enlargement surgery so they can make $5000 off of you.
