thats how i always recommend it... 2 weeks at 50 then every 7-10 days do 10 mg increments... never go over 100 but if your able to get to that point, then fucking awesome! just don't go too fast... wait AT LEAST 7 days each time you move up... like i said, you don't want to have to go 5 on and 2 off... the half life on s4 is a mere 4 hours so you don't want to have to miss any days if its not necessary... you know your body, just listen to it and your good brother...
