So you are taking 50mg dbol ED for the past 3 weeks? And what do you mean "im gonna finish taking the dbol" , how long were you planning on taking it?
And as far as "do i have to worry about nolvadex and that stuff" goes, the answer is yes. Dear god man.... you really have no idea what you are doing to yourself do you?
You are still too young to be cycling, you are underweight for what you could acheive naturally at your height, so when you posted in your stats "Diet - under control" is incorrect.
