Just FYI, I find that 100-150mg of transdermal
6-OXO to be ~= 600mg of oral androtrione, if not perhaps a little superior since you get a more continual and consistent influx of it into your system, so dose accordingly and make sure you know what you need for an effective dose.
Capping it is a much poorer choice in my opinion, because androtrione simply doesn't have a very high oral bioavailablility quotients (just like most other androgens).
