Testosterone Signaling Density

Meaning

Testosterone Signaling Density quantifies the cumulative effectiveness of testosterone’s biological action at the tissue level, integrating both the circulating concentration of free testosterone and the concentration and functional sensitivity of its androgen receptors (AR) within target cells. This metric is a more accurate indicator of androgenic status than simple serum levels alone, representing the true capacity for testosterone to elicit its anabolic and physiological effects. A higher density correlates with robust muscle maintenance, bone health, and libido. It is the measure of functional androgenic power.
