I'd say the tren, or epistane if you have that on hand, maybe even stack em or bridge from one into the other. Just something that gives quality gains without a lot of water retention. Didn't you say you had some tren ace on hand awhile back? That stuff would be perfect.
Like I said CLA will help, in studies 1g/kg bw caused a drop of something like 66% bf in a couple weeks, with a 20% increase in lbm.
Ephedra eca stack is easy and cheap too... Just buy some bronkaid from cvs. It'll help burn fat, and preserve muscle.
Oh and lots of water.
