I combined the two, but ran into prostate problems with this combo. I developed a urinary tract/bladder infection, as well as a possible prostate infection on this combo. That whole an uphill battle to clear up, even months down the road, and several courses of antibiotics. With the backed up health care system in my province it's been months waiting to see a urologist to get this checked up properly. I'd say proceed with caution, as I've also read quite a few other reports of infection problems of this sort from M1T. Whether it's due to immune suppression from this stuff, or the prostate swelling that comes from chronic ephedrine usage and subsequent prostate enlargement from severe androgens like M1T I can't say for certain. However I know I won't be going near M1T again as a result.
