T3 AND MD6

I have a bottle of Cynomel made by SB. I want to take this t3 the maximum way. Can I take this at 25 mcg a day for four weeks?.Do I need more or less. I am 250, need to drop 15-20 pounds. Can I take it with md6? What would be the minimal dosage of say a testosterone that would help me maintain muscle? Or would there be a better anabolic to take with it?

Good question,any help
