The above posts are correct your going to want milk thistle, and probablly liv52 aswell for pct. Anadrol can be a very nasty steriod, or a phenominal one it depends on your goals and your lifestyle while on cycle. If you train as hard and as heavy as you can with a good diet, maintain a huge protien intake and lots of calories with less fat you will get huge.
If you are sloppy and you miss days at the gym, eat like shit, and dont bother with pct its not going to do anything but make you irritable and miserable. pct is very important.
As for strength, back in the day a bombs were it. Some guys say then dont gain strength from them but everyone i know has. you will keep around 75% of it after pct, if done correctly. and about 60-70% of the weight gained, depending on how much water you take on. Drol is supressive, so have clomid and nolva ready for pct, arimidex is a good deal too during cycle. Anadrol doesnt convert to estrogen, it stimulates estrogen receptors. which can be even worse of a side effect if not taken care of properly. do lots of reading on pct.
