Animal test as well as other animal products are very effective for the average joe or a serious lifter. ive taken my first cycle of Test and about the second week into my cycle i noticed tremedous hypertrophy. It is not a steriod by any means the gains were not that signifigant but for someone who wants to increase size with a proper diet this will help you vastly. i highly recomend this product as well as the other products in the animal line
