There's a **** load of supplements out there that claim to have steroid like effects, aka "pro-hormones". E.g. anabol, like Mark McGuire used. There have been many university studies showing these have absolutely NO effect.

I don't know how MM got that big? Maybe he also used the real "gear" or actually busted his butt when using the supps and grew.

Haven't seen Palmeiro though. Usuually you can tell if they are juicing, the muscles just don't look natural -- Jose Conseco is a perfect example.
