Let me put an analogy for you.  If you have never taken a drink of booze before...would it be wise to start out with Beer or Everclear?  (I'm a sober alcoholic and do not condone either, BUT, this analogy is something I think we can all understand).
You don't need a hand grenade to kill a fly.  Start out with something MILD...it will be effective, you will like it, and it will leave you room for more in the future.  I have run TONS of aas and still have yet to touch TREN.  Stay away.
