The baking isle, or where you find jello. Its a gelatin-like powder. As for me, I took Cranberry Supplements, it is good for Urinary Tract functioning, not sure if that matters to guys but it helped me get clean in like 3 days. I smoked a 1/2 a j on Fri. And some hitters over Sat and Sun. Tues afternoon my strips were coming back neg. But keep in mind I'm also 5'2, 106lbs. i don't know your size or how much of what you smoke, so it differs from person to person. I also was going to dilute and started taking creatine to bring my levels up to par, someone on this site advised me that creatine was pretty dangerous to be taking, but no one ever answered my ? as to how much. Read the post by FareTheeWellNow, Dilution works, watch creatine levels. He's got a pretty good formula, maybe you can go off that, GOOD LUCK
