I would ask Haidut. He seems to have plenty of knowledge on the subject. Taking larger doses of the fat soluble vitamins would surely help (especially retinol).
I think taking DHT gel does not affect your 'regular' testosterone.
well I thought the more DHT you have or put into your system, your overall testosterone goes down, and if dht gets too high (and estrogen gets very low) your body would try to raise estrogen to get back to homeostasis...idk maybe I'm wrong here?
