Help in identifying these white pills

[The Butcher]

Sorry, no pics guys, so I'll have to describe them. They are white, and maybe slightly larger than a Nolvadex pill or a Reforvit Dbol Pill. There is a line on one side, and the flip side has Rx or Px on it. I'm pretty sure it is Rx, as the lower right leg of the R makes up part of the "x". They are high quality, ie, they are pressed well, and the markings are very distinct and visible. They should be one of three things. Either Proviron (but they don't match up with the other Proviron I got in that order), Aldactone (this is highly likely since I don't know what Aldactone pills should look like), or perhaps even Nolvadex (this is probably the least likely of the three). So, anyone got any ideas on what they might be? Oh, they came out of a Mx pharm if that helps to narrow it down a bit. Thanks.
