I would not suggest you use T3. Your thyroid is an important device and I don't recommend you screw with it until you feel that you are no longer a "novice" to the game.
The decision to embark on AS makes the decision to suck up the fear of a needle laughable. Take some time to think on how serious you really are about this.
If you simply refuse the needle, the only oral steriods that could be responsibly recommended to a novice are Winstrol, Primobolan tabs, and Oxandrolone (Anavar, etc.). These are within the acceptable hepatoxicity range, as well as relatively safe for the beginner.
Flame if you like, but Dianabol (or A-bombs) are not necessary or wise for a beginner, not to mention it is just too hepatoxic for someone not wise enough to carry out a complicated and expensive liver protection supplimentation.
I agree with Bill w. You could get your feet wet on Anavar at 40mg/ed. I'm sure you will get a million "Anavar is worthless" posts, but you will grow just fine on 40mg/ed if you eat well and train well. Cost will be an issue. If you decide not to take the responsibility of the needle, you can take the responsibility financially.
Good luck!
