Andro-1 was a nice show opener, don't you agree? Now for the big boys, let's get to work. Andro-4 is going to be the ideal product for your consumption in order to get the most from your gains. It has the same ingredients as Andro-1 (Androstene 3-17 dione, and Androsta 3-5 diene-7, 17-dione), but in greater proportions. This means that you will have an absolutely quicker time to gain musles, increase their vascular area, and give you the extra testosterone to supplement these changes. Drink away for the big boys!
