Just saw this thread. Yes you must consume saturated fats to survive. You can get away with eating a fairly large amount of them, if you keep your insulin levels in check and eat sufficent omega-3's, and to a lesser extent omega-6's. Increasing saturated fat intake can definately increases testosterone production, and reduce shbg levels, however this happens at greatly diminished returns past a certain point. Its also important to remember that if you are dificient in omega 3's, this effect will not occur. If your intake of saturated fat drops below what your body needs for at least optimal functoin, you will notice a drop in testosterone productoin, and even if you are injecting your adrogens, you will see diminished returns in muscle gains, althought they will not be as pronounced as those experienced by natural atheletes.
