well yes and no.
no in that test E won't show up on your blood test in black and white.
but yes in that your kidney values will be up, your test levels will be elevated, and your LH will be near 0. the typical imbecile doctor will look at your results and think you have kidney disease and some other problems even if you do tell him you juice.
if you wait a month after that still won't be long enough to not have elevated kidney values or a shutdown HPTA.
PS. i've asked docs point blank what are the sides from steroids just for fun and they either were clueless or they thought they messed with your livers.
