A few years ago, I looked into it.. Me another buddy tried it. my buddy thought it worked, but i didn't. Then after a few attempts, he came to the conclusion that it really didn't work that well. Its supposed to increase the effects. At least that is what their study says.. but, it didn't work for me, but it may work for others.. Its been so long that i did that experiment that I cant remember the particulars.. Ill have to do some more research on it..
