its possible depending on the steroid, a steroid in a carrier liquid or refrigerated suppository, absorbtion may be a problem depending on how much/if stool is in the rectum and contact with the rectal mucosa , again there is the issue of irritation and the suppository melting(which what happens) and causing a white goo to leak from your a-hole during deadlifts staining your gymshorts white, giving the the "workout buddies" that are always a little to "friendly" towards each other spotting each other from behind during dumbell kickbacks the wrong impression,not that there is anything wrong with that, so next time you are in the gym and they see you you try to grab every girls ass just to make sure they get the picture that you are not on their "team", a sublingual route would be more practical,,,,,,,,,,,,,,,,,,,,,,but less fun...........OOOOHHHHH
