I have been playing around with both during my hardcore cut, works great for focus when cal is low and I getting very lean. My question is, can I fail a steroid piss test?

Yes. They test for performance enhancer not just steroids. They half fairly short half lifes though

Oh, I thought that adderall might but wasn't sure about the T3, thought that a thyroid medicine might not "show" in a piss test..?
Thanks for you fast answer!
