Your body's already producing about 70mg of Test per week. Low dose means 100mg/wk? That means that the net gain of Test is 30mg/wk. For 30 mg/wk you're willing to have your natural production cease, have your nuts shrink, get acne, throw off your endo? Test is a powerful drug. It will absolutely work. Are you sure you can handle the consequences of the sides, if it happens to you? It won't be fun when you pull your pants down and the only thing stand up is the lamp post.
