Hey anyways i'm 18 as mentioned, 180 pounds and 8-9% body fat. Been training for about 3 years without many supplements.....few months of creatine, no2 products. I want to get down to about 5%, which has always been difficult for me as I have a lack of energy and extreme cravings. I was thinking of trying a light EC stack (8mg ephedrine a day to start and moving up to a max of 20mg with 200-300 mg caffeine per day; all split up in 2-3 doses). Should this be fine?
