First i'd like to say i've done a great deal of research, (or i like to think so anyways) and i've been training for about 6 years now and decided that i was ready to try steroids , however i want to make sure that i have everything down to a T before i start. I'd really like some feedback please.

I'll be taking, Dianabol (Terapia), Testosteron depo (Galenika) and Nolvadex (Zeneca). I've done some research and they all seem to be ligit.

1-4 weeks DBOL (25mg a day split up throughout the day)
1-6 weeks Test Depo (500mg a week, split up 3.5 days apart)
1-6 weeks Nolva (1 a day)

Along with this i'll be taking L-Tox (milk thistle), and have a diet of about 5000 calories, (i've pretty much got my diet down to perfection, course i've never done steroids so any tips there would be great)
I weigh 175lb and i'm 5'11.

Also, this may sound like a dumb question, but how do i know what size needle to use for injection with the test depo, i know it has to do with whether it's oil base or water base, however i have no idea how to tell?

Anyhoo, i'd really like any feedback and any tips.
