You have to take an ai with dbol in my opinion. I would even suggest at least a low dose of tamoxifen daily when on dbol. Also start diet while on dbol. Bulk but eat a clean diet with low sodium, lots of water, and do some cardio. Dbol can spike blood pressure very fast, bloat you, and cause gyno. In my experience it's the worse for these things. It can also cause hair loss so if you don't know if you are prone I would suggest washing your hair with nizoral.
