I support the blood work suggestion! Most likely your OK, but M1T is serious stuff. I just had a physical 2 weeks post M1T cycle and my kidneys were a little out of wack. I like many others experienced lower back pain while on my cycle. I choice to ignore it at the time, but now I think it was the M1T. I had another blood test the other day and my kidneys are improving, but not back to normal yet. BTW, I have always been VERY healthy - Never had a problem with blood work. I feel confident everything will be OK and will most likely do another M1T cycle, but I'll be watching things very closely next time. I agree with the Nolvadex suggestion too, but make sure your comfortable with the legal issues.
