My brother is 6' 1" 205lbs with about 18%bf he wants to lose 20lbs before graduation in may, is clen alright for an 18 year old? I told him that 20lbs in 5 months is super easy with the right diet, but i think he wants to lose it faster. Just looking for opinions. I know aas isnt for him for like 4-5 years, but he's been lifting hard and he's pretty freaking strong so he knows what he is doing, just working on that diet. Thanks guys
