While on this if you do a slight calorie deficit you will continue to lose weight, I believe there will be some recomp with this stack so I would opt for a slight calorie surplus and you will lose fat but maintain/gain muscle. If you want more mass slowly bring up the calories. The gains are very clean when you stack these. You may be suprised how much you can eat and still not gain fat. Feel it out but make sure your above maintenance to start.
