you can use it a million mgs a day if you want.. you ask "can you" as though you need permission.. you can do whatever you want whenever you want.. youre a gosh damn clown if you do run doses like that but to each their own.. the MAX you should run gw is 20 mg per day but like i said, you are free to do whatever you want.. only a fkng moron would run 100 mg of it per day
