Fantastic advice as always Oufinny, i agree completely. Katana is simply too damn expensive for what it does, and in my opinion SD is probably too strong for you. P-Mag or H-drol is the key right now, then hit up a solid maintenance period for a couple months, THEN look in to EPI. Putting your body through bulk and cut phases too fast is simply not smart both because it's very hard on the body and you have a great chance to mess up your composition.
