Somewhere I have a copy of a big study on this. I'll leave the googling to you, or just guess. I promise you that the results have implications...

interesting topic you got here, i received a news letter to one of my fitness site i join in, and according to one of the article, the normal value of testosterone level for male is between 300 - 1200 nanograms per deciliters (ng/dl) and the normal range for free testosterone (the actual active testosterone that your body can use) are: 8.7 - 25 picograms per mililiters (pg/ml)..well, i don't how the hell to measure my level but i long i'm not maladies of low testosterone i don't worry...heee!! yeah!!
