orals are the best steroids, no pain in the ass injections (literally) and you feel their effects within [/i]minutes[/i].
only problem is they are mythelated and pretty hard on liver doing it consistently for year round. liver just needs a breather from them and while you can probably multiple orals at high dosages for half a year without any permanent damage and likewise run orals for a full year straight, you'll definitely start to feel the negative effects on your liver from that.
no worse than drinking though, in fact i think alcohol is a lot worse on the liver it's just that most people don't drink to the point of being drunk every day of the week.
