Just a couple of points relating to lifestyle changes as a natural way to raise T levels.
1. adequate sleep with consistency (i'm guilty of training hard, eating well, but not going to bed at the right time); lack of sleep definitely influences hormone levels.
2. saturated and unsaturated fats in the diet; fats are our friend (in the right amounts) and certainly influence hormones production
3. finally, maca root powder has a positive impact on the endocrine system; though I haven't conducted my own lab experiments, I feel it contributes to my well-being; there are peer-review studies on maca root benefits, so worth considering.
