I ran the combo for 2 separate 2 week stints. I was ok during the first two weeks on m1t, and performed pct for 2 weeks before resuming the m1t/ephedrine combo again. The urinary symptoms cropped up during the second two week run, but I didn't think too much of it at the time, noting the my slate of symptoms was pretty commonplace for androgen users. When the urinary tract symptoms didn't clear up while after the second 2 weeks on m1t I got checked out by my doc, and the tests showed the presence of bacteria in my urine.
His answer was to prescribe antibiotics, the first of which didn't help much. When I tried a different one for 20 days, I thought I was free and clear, but the infection came back a week or so later with a vengeance. So all told, I've been dealing with this since around Christmas or so. Add in a 2-3 month wait to see a damn urologist and that's where I'm at now, still another month or so to wait. I've been megadosing vitamin c, olive leaf extract (an excellent anti-bacterial supplement) and high dosing a high potency cranberry extract, and I'm finally nearly symptom free. I'll still get checked out by the urologist when my appointment comes up in a months time, but I may just be recovered on my own by then with my current supplement regimen.
Which is good news, because I have my hands on 3 bottles of sledge's m-dien in my hands, and 3 bottles of m4ohn on the way as well, and am itching to stack the 2 together.
