After many years as the Metabolic Doc, I've realized the care I'm providing is best described as a new sub-specialty of Internal Medicine: Testosteronology. You can still call me the Metabolic Doc, but moving forward my focus is on Testosteronology.

While caring for thousands of men on testosterone and anabolic steroids I've learned a lot about how other medical specialists prescribe testosterone. I've found that no other specialty offers comprehensive and personalized medical services for men on androgens.

Testosteronology is distinct from Endocrinology and Urology: Testosteronology is more specific than Endocrinology, which deals with all hormones in men and women. And it is different from Urology, also known as genitourinary surgery, which focuses on the mechanics of the genitals and does not consider the cardiovascular implications of androgens.


With this name change, my medical practice provides the same specialized medical services for men: Testosterone Replacement Therapy, Anabolic Recovery Medicine, and Cardio-Metabolic Men’s Health – focusing on aggressive prevention of cardiovascular disease, quality of life, and prostate health.

Aside from the logo change, you'll find most of the site is the same - at least for now. Stay tuned for some updates coming soon!

Stay Strong and Healthy,

Dr. O
