Shit i still reckon 600mg is too much for a first cycle, 35lb gain that fast is crazy, could be a lot of fat and that could explain the estro sides. I'm just speculating, but from what i've read about 25lbs LBM gain after a first cycle done properly would be exceptional. Which is about 4 years work in 12 weeks for an intermediate lifter, no wonder dat dere is so tempting.
Also i really hate chest training, thought i could put up 34kg DB for 4 or 5 reps flat bench, got one rep. Struggled to get 30kg for 2 x 5. My bench is a good 15kg weaker per hand than my DB row, pretty sure thats the opposite of everyone else in the gym. I'm also stronger on a low incline, im guessing because im delt dominant but it also seems easier to get a good stable position on an incline.
