SWIM just received 2 free sample packets of AMP, it contains Chocamine and Geranamine, with some caffeine. Has anyone tried this stuff yet? I've heard good things about it, just wanted to know what you guys thought about the product. He has 4 pills, says to take 2-4 once per day. Not sure if I want to take 2 or 4 as he doesn't have any more. What do you guys think? Thanks, peace.
