At 51 I decided to have my testosterone levels checked. Sure enough, my Testosterone were low. I went to Dr.Hahn’s clinic. He spent at least an hour with me one one for my consult. I started on testosterone replacement therapy, Natasha and Teresa at the office are awesome, I wouldn’t go anywhere else. My T levels are optimal now and they lab test my Testosterone levels every three months to be sure My T levels are optimal and adjust my dosage accordingly. I love the way I feel more energy, mental acuity is high I feel like I did in my early thirties. Thank you Dr. Hahn!
