You are going to have to go to an anti-aging/longevity clinic for what you are seeking.
No specialist such as an endocrinologist or urologist is going to be receptive to anything other than helping you acheive normal or within lab recomended levels of any hormones.
My close friend has clinics in port saint luice and West Palm
Is that close enough? He's a Mayo Clinic trained plastic surgeon with an anti aging clinic. Very cool guy and he walks the walk. And he gave my wife amazing implants. We have been Friends for 20 years. PM me for contact if you are interested.
