Dht blocker hard capsules work by interfering with the two main factors that contribute to excess Dht: the enzyme that converts testosterone into Dht (5-alpha reductase) and the receptors that bind Dht to target tissues (androgen receptors). By inhibiting the enzyme or blocking the receptors, Dht blocker hard capsules can lower the levels of Dht in your blood and tissues, and reduce its effects on your hair follicles, prostate gland, and other organs.
