I'm sure Mr Big will comment on this and IMO his opinion would be worth more than mine but I'd say:
Keep the test prop in at 50 mg/d up to the show, dropping test completely will make you lose thickness and look weak. You can be dry on 50 mg/d test prop
100 mg tren ace ED....hmm there is a risk you could go flat. How do you respond to tren ace? Have you ran it high before?
Mast prop at 100 mg ED would likely make you look dry, cut etc generally more conditioned but again you can go stringy
Keep anavar the same
Not sure about the stanozonol, maybe go to 50 mg ed?
T3 should be okay I think, again depends of how you have responded to it
Anadrol for sure IMO at at least 100 mg ED at <=7% bf... I'd go with 150 mg ED.
Honestly I wouldn't have used the letro to nuke your estrogen but it is too late now, if you come off it or adjust the dose you'd probably rebound and ruin everything. Don't ever nuke estrogen, it is very important for losing fat, adding muscle, feeling good and motivated and energized, sex drive and importantly for you LOOKING FULL AND THICK
Hopefully Mr Big will chime in with his expertise! He is the competitor here, he is the aspiring pro! He is the guy who looks like a freak.
