Personally, I would not run two methyls at once. However, there are some who don't have a problem with it. I'm not going to preach about it because the issue has been debated over-and-over here.
One thing I would suggest, if you choose to do these two together, keep an eye on your b/p. Also, make sure to take a good liver protectant.
M1T and 5aa cyp I believe would be a better stack.
