My gf works at gnc so I get a bunch of free samples and have used the bpi blox for awhile. I havent noticed a huge difference and ive been taking one serving post workout. So I probably wouldnt waste my money unless you have some expendable income.
they are bullshit and dont let anyone else tell you otherwise. a 180lb male would have to take 66g of the stuff in order to take the same doses as the rats in the study were given...just no.
