How can you increase dht (dihydrotestosterone) levels?

Why do u want more?: Testosterone is metabolized (broken down) into Dht & Estradiol (e2). Testosterone is anabolic (makes muscles grow). Dht is androgenic (makes you more male). But too much Dht can also lead to hair loss and prostate enlargement. So we don't typically try to raise Dht (although if you take an aromatase inhibitor to shut down e2, you might raise Dht via seesaw effect), rather we lower Dht via 5ari.
