If you're "new" then you don't need any steroids at all. First of all, if you're 30% body fat, you need to work on your diet and start doing cardio. Get down to at least 15% or so, and get a good base from at least a couple years of training under your belt, or you will waste money and time.
But since that's probably not what you're looking to hear, and you're going to do a cycle anyway, your "friend" is a complete moron. If you run 40mg of Winny along with Tren, and no Test base you can kiss your sex drive goodbye for months. You won't be able to get it up, nor will you be interested either.
If you are going to run a first cycle, do something like:
Wk 1-12: Test E 500mg every week (split into two shots, monday+thursday)
Wk 7-12: Winny @ 50mg Every Day or Wk 1-6: Dbol 40mg Every Day
