Tweetif you're worried about your hair loss and your hair is already thinning...then either don't run it if you want as much hair as possible, or suck it up, use it and shave your head. your call.
even at 6'5", 250-260 and single digits is pretty damn well bb'er huge,lol.
i'd say it looks fine. if you want to add 6-8 weeks of something, pick up some var to run the last 6 to 8 weeks up until a few days before pct at around 40-60mg/day.
the original cycle you have posted looks great, shows you've done some research. good luck
