im almost 100% sure anabolic androgenic steroids do not burn fat. for example...Winstrol - stanozolol. people think Winstrol - stanozolol is such a great fat burning steroid but in reality all it does is enable you to hang onto muscle tissue while cutting. this way by doing all your cardio and dieting and taking Winstrol - stanozolol at the same time youve salvaged most of the muscle you had before you dieted and this way you look a lot more defined because the muscle is still there. in that sense anabolic androgenic steroids isnt exactly thermogenic.
