bro you say you have just started to get into working out and already you want to jump to the AAS, don't do it to your self...your body has never felt what it's like to work out before right....I mean being on a good eating schedual and working each musle on alternate days and all?? for real don't just jump on the sause right now give your self a gaol first see if you can get there on your own..you say you are 23 and weigh about 120...
tell your self that by next summer you will be 150 you are already lean so if your eating is right on, you will only build lean musle..right now you have the upper hand to some one on roids bro, you are already lean........
get as far as you can by eating right and working out, you never know by next summer you could be up to 170 and lean, and for youe age not sure how tall you are but that's a good place to start.....
once you see you can't grow any more then sit down and do research on AAS, I did 3 years of research on AAS before I even baught anything, and when I got it I still waited for another year just to find out that much more about exactly what it is I have....
hope this helps but hey if you already have your mind on taking stuff then that's your call, just do your self and your body a favor, do as much research as you can.....
and if this post was a joke it should be left up because many people come to this site looking for an easy way to loose weight or get huge, but in the long run it is those people who want a quick fix that get injured, or die young due to heart problems or get bad sides and blame the site or the people who gave them input, this site is for people to research try to understand what effects certain things have on other people and so on, every one reacts different on any compound so research is the only key any one has in order to make an informed decision....
just my .02
but the cycle I'm on is working great.....
