Yes methyltrienolone is 17-aa methylated tren.
Never tried it yet, I may do in the future, and again i may not.
To comment again on the issue, Ive never done 200 mg dbol ED either, and im not going to since i hate that compound anyway

, but labeling people abusers or whatever isnt the way to go. You can still use such amounts RESPONSIBLY, if only for the sake of experimenting. I doubt that 2-3 weeks of it will do any irreversible damage to anything. If youre really concerned, yet want to experiment, its always nice to do a blood test and stop if you notice values elevating too much. This is responsible usage in my opinion, and it has nothing to do with the dose used.
Another thing - I bet most people in the 70's would say the same thing about using 1+ g of test/weekly, yet nowadays so many people happily do it.
