You REALLY stay at 5% year round. PROPS! Propecia (Finasteride) will reduce the levels of DHT in your body significantly. This will probably lead to a "softer" appearance. Actually, using finasteride will INCREASE testosterone levels around 20%. By preventing the conversion of Testosterone into DHT, more unbound Test will be circulating. But it seems that DHT is very important for maintaing a "hard look". That's why most of the DHT derivatives are used to "harden" up. Lowering DHT will definately hinder your low bodyfat goals. Maybe not that much, it's hard to say. Are you also using gear? That changes things.
