Some say it help them metabolize nutrients during bulking. For me I shrink on ANY dose (even 25mcg) and stay flat. Try it for a week and see how you respond.
very high androgen levels in the body might supress tsh levels a little , so 25 mcg ed would normalise things , but then again i think on high carbs and some guggulsterones , u should be fine , why unnecessarily mess with things u know ?
