I recently found I may be a candidate for testosterone replacement therapy (TRT), however i was curious if anyone with any experience with it knows what type of costs are related with this treatment and if insurance will cover any of the expense. Also, I'm 35, is that normally to young to get on because from what i understand, once u start u have to stay on for life?? And, secondally, i heard it cause prostate cancer? thats scary. any input would be great, thanks.
