Greetings, thank you for this information. You have already written about a lot of things, but I would like to add that testosterone, or rather its level in the body may also depend on stress. When you are stressed, your body produces a hormone called cortisol. This hormone helps your body prepare for and respond to this stress, and then your body returns to normal. But when you are stressed more often than not (chronic stress), you experience prolonged cortisol exposure-and studies show that cortisol circulating in the bloodstream lowers free testosterone levels. In order to increase your testosterone levels, you can take Revange Nutrition Test Restore daily. This product can easily help you if you are deficient in testosterone.
