The best time to make gains is right after a show after you're all dieted down. You body is primed for growth. Dorian knew this very well. While Flex, Shawn and others were taking months off afterward going on vacations and cruises and shit. Dorian was right back at the gym on a high calorie diet. Your body makes phenomenal gain after a hard diet and that is exactly what Branch is doing.
While I agree with this, I don't think Branch has put on 40 NEW lbs of muscle. Maybe a pound or 2 at best. The rest is water, ie: Edema. This is NOT smart, it's NOT taking advantage of a rebound.
Like I said, he's huge, nasty and has awesome muscularity. However I just don't see him giving a shizzle about his health.
And no, you can't "see" high blood pressure. It's just a guess, but i'd put money on it!
