you cannot say yes or no. it all depends on who you are. most people on this board know that theoretically, yes, you would get shut down off of 250 a week....but some are more resistant than others. i didn't get shut down off of 875 mg test/week, actually i came in larger amounts, and afterwards even 2 monthes out, suffered no side affects of diminished testosterone levels. so you won't know until you actually try it.
