t have such symptoms as reduced growth of the beard, lack of hair on the legs,
gynecomastia. You really weigh little, try to work out (training with iron)
and see if muscle mass increases or not. If testosterone is all right, then you will be gaining muscles. At the same time, libido will also increase. And do stop smoking, pity your blood vessels. If you didn't feel negative effects of smoking at 18, the situation at 23 can be different.
