TESTin' positive?

I’ve got a good question for the board. I compete in I.O.C. regulated competitions. I’m 25 y.o. and have a test level of 425 ng/dl. My question is whether or not I could take a sust-250 rediject once a week w/o gettin busted. My natural T levels are so low I suspect the injections would bring me closer to the 1000 ng/dl limt. Any info or ideas would be greatly appreciated.
