I would not suggest dbol for anything related to running. You will get some decent fluid retention from dbol which is great for lifting weights, but if you try to run, you will redefine the word "pump" haha. The pumps you get in your calves will leave you unable to walk, promise! Lol, I know first hand and have seen it in countless others. I would stick with a low dose of test and an AI or I would maybe go with a compound that doesn't convert to estrogen like anavar, if you would like to use an oral. Ideally, the test would be better
