Buy it from supp warehouses like custom nutrition warehouse, prosource etc.. I used it before and will use it again during pct. I liked it very much. It helped with increase in test, strength, energy. Plus you only have to take one pill before workouts. I just took one pill everyday. It's a 30 day supply and you're looking at the same number pretty much for price if you go to supp warehouses. If you buy it at GNC you'll pay some rediculas price.
