When you take Phase One Nutrition – Mass Stack (AndroMass and Cyclevar) together the main benefits from the stack would be increasing the daily intake of Eipandrosterone. When using these two products together you are intaking a daily dosage of Epianderosterone at 800mg a day. This may put your body in the ultimate mass building mode. This stack may also increase your appetite, and may help increase your strength gains. This may lead to increased muscle gains while decreasing body fat at the same time. The most important thing is that you are getting Arimistane already built into the AndroMass, this may help reduce estrogen in the body and allows for better gains.
