Had blood work done. Total testosterone came back at 489. Free test at 7.5. Doc said that I am a candidate for TRT. I know this is how these guys make their money, so I wanted to see what others thought first. I would rather not go on TRT. I'm 33. Vitamin D3 was a little low. Estradiol was not checked. Cholesterol was excellent. Is there a way to rectify the free test naturally. Tongkat Ali? DAA?
