With me I just used m1t for a month and only used ZMA and Trib because i thought that would be enough for the M1t.
I would suspect that could be most of the reason why, if any, estrogen production may have elevated faster then your natural test (depending on how much you suppressed your test production) and because you had nothing to essentially block the estro from doing so...the trib should raise your LH hormone which would help increase your natural test prod, but you need something like NovedexXT or Formadrol to help your body from aromatizing into estrogen.
How long did you run the M1t cycle???.....
