4 ad ec dosage

Hello guys, just have a question regarding 4 AD EC and its recommended use, I didn’t find anything regarding it on Biotest’s website. I want to use it during Fat Fast instead of Androsol,it seems to be easier to use and more effective, the thing is I don’t know how to dose it as I’d like an equivalent of a normal use for Androsol indeed my main goal is to keep my LBM, not to gain mass.

An answer from my fellow T-maggers would be very appreciated.
