Nah man you arent talkign ****, but you have to remember the biggest gains you'll ever make are when you first start. I've been lifting seriously for about 7 years now and EVERYONE thought i was always on AAS. I just have very good genetics for size and proprtion (my legs have always been big, stomach is flat, and I always had big arms). But what Nate said is spot on. Why to pro bodybuilders take such insane doses? Because once you enter the mid 200 lb level its that much harder to climb. Think of it this way. I hope you're into cars cus if not this will make no sense...But lets say you buy a MK IV supra twin turbo, 320 hp stock. So the first thing you do is some BPU stuff (chip, intake, exhaust) and you get 450 hp. Nice gain. (this is equivalent to about a year of natural lifting and diet alone). So then you decide to step it up, do a single turbo swap, build the motor, etc and now you're looking at anywhere from 600-1000 hp (this is equivalent to starting AAS). But now what happens if when you first bought the car it already had a single turbo swap (this is me, the 230 lb 5'10" natural lifter)...there's not much you can do to get it more power, and what you do end up doing will be very expensive and will require lots of upkeep.
Hope that made some sense.
And as far as 12lbs in 5 weeks, bodyweight on AAS is the biggest misconception in the world, at least for someone who is trying to refine their physique and not just get bigger. Sure if i was 170 lbs i'd start with 30 mg dbol, some test, and maybe deca and i'd blow up like a balloon from the water retention and also because I have that much more room to grow. But you have to take into account where i started from in regard to AAS. Nevertheless, i dont doubt i'll end the cycle at 260-265 lbs. Which will be rather insane. Also as i said earlier, I'm on arimidex everyday and i've also gotten leaner during the cycle, so 12 lb gain plus loss of a pounds of fat makes it more like a 20 lb swing. But i've always said I could care less what i weigh. It's all about how i look, and i always have used my waist size as a barometer for that, and of course, the mirror.
I'll update pics week 9 or so and let everyone know how its goin.
