Im 22 and Im wondering what test booster I could take that wouldnt test dirty if tested by a very scrutinizing testing agency if they ever came through. Is there any out there that are safe and actually work very well that will pass?? I cant risk anything because i have one more year and off I go. Just lookin for a little edge and nothing to big. I take protein, kre-alkaline, cellucore d4 extreme, flaxseed, joint support, fiber, multivitamin and a very stict eating regiment. Im 6'7" 310 with 11% bodyfat. eat about 5,300 very clean cal. a day. Though im big and lean, even at that weight im just not massive enough. i want to put on some good mass but stay fit and cut. What do you all recommend I do? any suggestions would be absolutely great!
