A Urologist’s Perspective
Patients often expect a simple answer:
“Which TRT is best?”
The reality is that success depends less on the product itself and more on:
Proper Patient Selection
Consistent Use
Monitoring
Realistic Expectations
I’ve seen patients thrive on Nebido and others do exceptionally well with gel.
The right choice is usually the one that best fits the patient’s lifestyle, treatment goals, and willingness to adhere to therapy.
Final Verdict
Both testosterone injections and testosterone gel are highly effective TRT options.
Injections offer:

- No skin transfer risk
- Long-acting options such as Nebido
Gels offer:
