^^ how old are you?
don't get suckered into worrying what the scale says or what your 'friend' did.
if your friend is 6 feet 150 of course he is gonna put on more weight on roids. cause the guy is so below his genetic potential its easy to gain just going to the gym and putting on water weight!
so don't compare yourself to others.
if you aren't satisfied with 8 pounds then steroids probably aren't for you, seems like you want to turn into mr olympia after 1 cycle and you have no patience. bodybuilding takes years, its not easy to grow muscle and keep off fat, thats why its so challenging. lets see where you are at in 5 years, not 5 weeks
