tess-TOSS-ter-own
The primary male sex hormone — replacement therapy restores levels when your body isn't making enough.
Also known as: Testosterone Cypionate, Test C, TRT
FDA approved for: Male hypogonadism (low testosterone)
Last reviewed: April 2026
Testosterone is the hormone responsible for muscle mass, bone density, energy, sex drive, and mood in men. When levels drop below normal — due to age, stress, or medical conditions — replacement therapy brings them back into a healthy range. This isn't about getting to supraphysiological levels. It's about restoring what your body should be producing.

Direct replacement vs. gonadorelin which stimulates your own production. TRT is more potent but can suppress natural production and fertility.
Gonadorelin
A natural hormone analog that tells your body to produce its own testosterone — preserves fertility unlike direct TRT.
DHEA
A precursor hormone that your adrenal glands make — your body converts it into testosterone and estrogen as needed.
