Why do you say that?
because you'll do your first shot and stay awake most that night from the influx of androgens.. wake up in the am expecting to feel tired from lack of sleep, but you'll feel just fine.
next day you'll start your first day as a 'steroid using bodybuilder' and have great workouts just from the psychological 'boost' in knowing you have androgens in your system.
first couple weeks you'll feel what a 'real' pump feels like and so on... this will go on for a couple months, all the while you'll be waiting for any of the 'side effects' you hear about, but they won't come and you'll think 'what's the big deal?'... you'll make gains in LBM and strength, your sex drive, 'ambition' and assertiveness will increase, and your bodyfat will decrease... but then you'll get used to it and you won't feel any different and you'll be curious "if I don't have anything by good results from 250/wk, why not use 500mg/wk? or why not add some deca to get some synergy going? I can afford it.. it's cheaper than supplements at GNC".
you'll find out 'the world isn't really flat' and big dosages dont' give the horrible side effects most say they will.
just remember bodybuilding, even for steroid using bbers, is 80% diet. the better you eat, the better you look.
