When choosing bodybuilding supplements, the question of “stacking versus not stacking” always comes to mind. In the case of Testosterone and Winstrol, stacking the two together is not usually necessary. Both of these supplements work to build lean muscle mass, increase endurance and overall strength. However, there are differences between the two that should be considered. Depending on your specific goals, one may be preferable to the other. For example, if you are currently in a bulking cycle, Testosterone would be the preferred choice. If you are currently in a cutting cycle, either one would be a great option. If you would like to increase your male libido and sex drive at the same time as you are working on a killer body, Testosterone can help you achieve both objectives simultaneously. If bloat and excess water are obscuring your killer abs and muscle mass, Winstrol can help you shed the excess water.
