Hey guys been looking hard for a designer steroid that will not pop on a standard steroid drug test, I know certain prohormones will, I've been told due to epistanes unique chemical structure it or it's metabolites will not show up as a positive for any specific steroid, however it may make you fail the Test/ Epi test ratio.. Which for me is fine because I have a valid script for testosterone (TRT) anyone can shed any light on this it woukd be greatly appreciated thank you !
