I'd consider perhaps adding proviron in near the end to help with SHBG. But honestly man I'd start small. Run say 300/week 1:1 Tren to mast or even 75mg eod of each with the same test dose. Keeping diet the same, and look to recomp, and then we you need another stimulus bump it up. Keep it simple.
See how you react to a smaller dose, and then bump it when you hit a plateau. don't run the same dose 6+ weeks. That is unless you're really just trying to squeeze the last little bit out of this - then I'd take the higher for shorter period.
