My thoughts on it is if your looking to do a test/tren/mast I would stick to the 100mgs per compound EOD, you can up your tren/mast dose as needed from that point. Drop the Winstrol (winny) or var and save those for later on as your already introducing 2 new compounds to your body. Personally I would be using mast ace instead of enanthate as you will be almost half way done your tren before the mast is at full force.
The whole key to this stack is going to be your diet, with an extremely clean well planned diet it can do wonders at preserving muscle while you diet to shed the fat.
