Go with M1D or 4-ad stacked with Superdrol if those are really your only options. It is possible that you won't notice any effect from MMV3 if you're running it with Superdrol (which is one of the most potent steroids on the market) but M1D might help you to fight side-effects caused by Superdrol..
M1T is so harsh that nobody should use it and 4-AD is quite similar to M1D from Trifecta Stack so those are not good compounds to stack with Trifecta.
I don't know what Methyl-Dien is though but if it is what I think it is it's very harsh stuff too..
So my advice is to go with just Trifecta Stack or, if you want some more potent, stack Superdrol with M1D or 4-AD... But it would be wiser to buy something milder like Epi IMHO.
