Well for one are you really 6'9 180?
I wouldn't take it seven weeks personally. I'd stick to six and if your stats are correct stick around 80-90mg a day straight through. No reason to pyramid it. Make sure you have a Serm and make sure you're girlfriend/wife/boyfriend/your bottle of lotion/whatever you have if you have anything doesn't want to have sex for a while because that stuff is a libido KILLER.
