hey havoc, theres a huge amount of info around here on both of those compounds .. but the condensed version is that superdrol is generally accepted to give worse sides along with a substantial level of hepatoxicity..
which one is best for you would probably depend on what exactly you were looking for .. if your cutting i would probably go with halo, if you're bulking i would probably go with super..
also i wouldn't really recommend superdrol for a first cycle cause its a pretty powerful sum*****.. but without more details this is probably as much as you're gonna hear! good luck either way buddy :thumbsup:
