What is the Origin of Testosterone Energy Levels?

This concept is a cornerstone of male and female endocrinology, linking the anabolic and metabolic functions of testosterone to the subjective experience of energy.

What is the Mechanism of Testosterone Energy Levels?

Testosterone acts by binding to androgen receptors in various tissues, promoting gene expression for mitochondrial biogenesis and increasing the efficiency of glucose and lipid utilization in muscle cells. It also plays a permissive role in the central nervous system, influencing neurotransmitter systems that govern motivation and mood, thereby boosting perceived energy and mental drive.
