About Testosteronology.com
Testosteronology.com is a focused medical education portal created to address one of the most complex and rapidly expanding areas of modern health care: testosterone, TRT, androgen therapies, anabolic steroids, and the interconnected systems they influence.
Developed by Dr. Thomas O’Connor, Founder of Testosteronology®, the site provides men on testosterone with greater clarity, structure, and depth in an area where demand has grown faster than traditional medical education has been able to adapt. Rather than functioning as a general health resource, the platform is intentionally specialized, helping members better understand how testosterone and androgens can affect symptoms, laboratory markers, performance, aging, cardiovascular health, kidney health, blood pressure, sleep, sexual health, and other important areas of long-term health.
What distinguishes Testosteronology® is its focused approach to understanding the whole-health impact of testosterone and androgen use. The educational content is designed to go beyond testosterone levels alone and help members understand the broader health markers, conditions, medications, and physiological systems that may be affected over time.
Dr. O’Connor brings decades of experience caring for men using testosterone and anabolic steroids to the educational resources available throughout the platform. His approach emphasizes understanding the potential benefits of testosterone while also recognizing the risks, complications, warning signs, and long-term health considerations that every man using testosterone should be aware of.
Membership provides access to an extensive and continually expanding library of educational resources, including hundreds of in-depth articles and videos covering the subjects that matter most to men on testosterone. Members can explore topics directly related to their laboratory results, medications, symptoms, performance goals, and long-term health concerns, making the educational experience practical and relevant to their individual situations.
The platform is designed to help men become better informed participants in their own health care. By understanding what to track, what to watch for, and the questions that deserve attention over time, members can have more informed conversations with their personal health care providers and take greater control of their long-term health while on testosterone.
As the field of Testosteronology® continues to evolve, Testosteronology.com will continue expanding its educational resources to help men better understand testosterone, androgens, anabolic steroids, related medications, and the many areas of health they can influence, all through an affordable monthly membership.

I created Testosteronology®, a focused subspecialty of Internal Medicine developed after many years of caring for thousands of men and women using testosterone and anabolic steroids in both therapeutic and non-therapeutic contexts. No other medical discipline provides the same comprehensive, personalized medical oversight for individuals on androgens across real-world dosing patterns, comorbidities, and long-term risk tradeoffs. Testosteronology® stands apart from Endocrinology and Urology because it is more focused than Endocrinology, which addresses all hormones broadly, and distinct from Urology, a surgical specialty that does not concentrate on the complex medical consequences of androgen use.
Testosteronology® centers on the real-world physiological and psychological impacts of androgens, including cardiovascular complications, androgen-induced erythrocytosis, mood and behavioral changes, fertility considerations, and the full spectrum of Internal Medicine-related conditions arising from therapeutic or non-therapeutic androgen exposure. As the discipline matured, the need for a formal professional home became clear, so I established the Testosteronology Society® to advance this specialty and support clinicians who practice within it. The Testosteronology Society® formalizes the discipline, sets clinical standards, drives new research, provides professional development, and protects the integrity of Testosteronology® as the leading authority on androgen-related medical care.
After the Testosteronology Society® was established and its clinician community began shaping shared standards and clinical language, I, together with the members of the Testosteronology Society®, created the Testosteronology® Health Portal as a service of the Testosteronology Society®. The Testosteronology® Health Portal delivers structured education and practical clinical framing that helps members make sense of symptoms, labs, outcomes, and long-term risk in both men and women. It also expands access to Certified Testosteronologist® support and clinical thinking, so members are not forced to navigate androgen-related decisions without an informed, standards-based reference point. In addition, the Testosteronology® Health Portal digitizes the ABCDS™ Framework so every member can track and trend blood work over time, monitor meaningful patterns, and become a more informed, engaged health advocate while staying aligned with the mission and standards of the Testosteronology Society®.

Omar Hajmousa, PharmD – Director of Education and Strategy
I joined Testosteronology® as a Doctor of Pharmacy, graduating with my PharmD from The Ohio State University, with the goal of deepening my expertise in the systemic effects of testosterone and its clinical role in treatment, prevention, and health optimization. My background in pharmacology and complex medication management gives me a unique lens through which to assess androgen therapy, including its mechanisms, benefits, risks, and the critical nuances that influence patient outcomes.
Inspired by Dr. Thomas O’Connor’s pioneering work, clinical philosophy, and unwavering leadership in androgen care and harm reduction, I have committed my career to advancing the field he founded. Dr. O’Connor’s creation of Testosteronology®, and later the Testosteronology Society®, where he serves as Founder and Chief, has established a new standard of excellence for managing the medical, psychological, and physiological consequences of androgen use. His mentorship and vision continue to shape my professional development and guide my contributions to the Society.
Appointed by Dr. O’Connor to serve within the Testosteronology Society®, my mission is to help expand the global reach of this specialty while empowering healthcare providers with the knowledge, tools, and evidence-based practices necessary to deliver exceptional androgen-related care. I work to support the Society’s initiatives in education, clinical collaboration, research development, and professional training, ensuring that current and future clinicians uphold the highest standards of patient-centered, ethically grounded hormone and androgen management.
Through this work, I am dedicated to advancing Dr. O’Connor’s legacy and helping men and women worldwide access safer, more informed, and more compassionate androgen care rooted in the principles of Testosteronology®.
