It seems some really struggle with blood sugar on mk so it wouldn't hurt to monitor bipod glucose which is cheap. You can run it months as long as you don't become insulin resistant. I've never had a problem with it but I have a manual labor job, plus jogging with my dog, and being lean make a diffrence I'm sure. Even still I plan on adding berberine in with it next time I run it plus checking bg. If you never used any steroids and just started trt I'd see how that treats you first. But yeah you can add anavar or any steroid you want really just keep in mind on trt I think you have to get blood test every few months so you probably don't want anything out of range during those times.
