I will be a bit different from the rest of the members, and will rather recommend you to run anavar stacked with turinabol. In my opinion it is the best way to get a lean bulking cycle. Tbol will allow you to gain quite a good muscle mass with no water retention of fat accumulation. Anavar will help to keep things lean and dry. Taking 20-30 mgs of each per day would give you quite amazing results. With these compounds you will not need an AI, since none of them will aromatise into estrogen. What you may do, is add in there some proviron, as it is not liver toxic, but it will increase free testosterone levels. Sounds to me like quite a good oral-only stack. Also, it would be great to add in there a couple of SARMS, as they will improve performance at no cost at all in terms of side effects. Obviously, with the above mentioned steroids you should definitely run a very comprehensive liver supporting supplement, such as N2Guard.
