Bulgarian Tribulus terrestris

The most important hormones in the male body are called androgens. Even though testosterone  is  the main hormone of that group, the biggest androgen signal in the human body is obtained from  another hormone - dihydrotestosterone (DHT). This hormone helps the development of male outer  traits and protects you from the effects of estrogens. DHT is responsible for the hair growth, muscle growth and strength, as well as for increase in the sexuality and libido.
