Jacked bro...looking good holmes. If doing the 6 weeker, make sure to get some bloodwork afterwords. SD is known to mess up cholesterol and the like, so be weary of that. Otherwise, if you're still growing like you said, then I agree might as well milk it...but no longer than 6 weeks.
For PCT, I would rather you use nolva/clomid, but RXT will suffice....but again, just keep an eye on cholesterol. Additonal things for PCT would include lean xtreme for cortisol reduction, a creatine/volumizer like V12 or one of the custom mixes that customnutritionwarehouse sells; a partioner such as GXR, or ephedrine, etc...any more questions, feel free to ask. Good luck with everything bud.
