Sustanon is not that hot @ 1 shot per week, the short-esters release fast--and there are 150mg of short esters in Sustanon, so about half the week you have very little testosterone in your system--the rest of the week you have a lot.

And Pete's right. 6 weeks is just too short. By the time you get started, your cycle wil be over. I am doing Sustanon now--it took 4 weeks for it to really kick in!

Do you have anti-estrogens? Clomid? You should have them!

And I'll bump what Pete said about the age.

One side effect of steroids is "Premature epiphyseal closure" which means the ends of your bones MAY close before the time that they normally would becasue of using steroids, thus locking you into your current height. IT IS IRREVERSIBLE. That means once you close them--that's the height/size you are gonna be. No, it doesn't happen to everybody--but it does happen to some guys and it would suck if it happened to you ! (I am 6'4" and I love being tall. I wouldn't trade an inch of it for 20lbs of muscle!)

At 122lbs you are definitely not at your full potential--you can easily grow a lot bigger naturally. If you eat lots of quality food and workout hard, you WILL pack on some muscle. Your youth is in your favor--you have a lot of natural testosterone; use what God gave you. Taking AS will temporarily shut down your testosterone production, so most of the Sustanon @ 250mg a week is just replacing what you would have had in your system if you HAD NOT taken any steroids!

Save the gear for a while & stay natural--you can grow like a weed on nothin' but hard work and good food.

Search AR , google and other web sites on "steroids AND epiphyseal" for more information before you decide to take any steroids. Keep doing research--knowledge pays off manyfold if and when you decide to do AS.

Good luck!
