Once I used M1T as a cutter, along with ECA. I took 20mg/day split into two doses (morning and afternoon). My appetite, libido and energy were almost nonexistant. Blood pressure was up, and I was irritable. It was so unbearable I only lasted 8 days before quitting.
The second time I used M1T I again used it 20 mg/day, but in a single morning dose (not as a cutter) for four weeks. Blood pressure was fine, and I was always in a good mood, although somewhat aggressive. My appetite was tremendous! Libido was so great that I could sometimes have intercourse twice in a row (with a 30-45 minute break, of course). PCT was a breeze.
I blame part of the negative side effects with my first try with M1T on some kind of bad synergy with the ephedrine. I was lucky to not have had the problems others do with M1T my second time around.
