There are endocrinologist that know what they're doing with TRT but there are just as many if not more that do not. That may not seem possible being that endos are hormone doctors, but most have zero concept of TRT. Most spend their time treating diabetes, thyroid problems, etc. Hopefully yours will be a good fit, but a word of encouragement, don't get too caught up in doctor titles. The only thing that matters is if the doctor understands TRT. Some of the best TRT doctors in the country are general practitioners, which is probably surprising to hear for some people.
