Deca-Durabolin differs in its chemical composition from testosterone in that it lacks a carbon atom in its 19 position and because of this Deca-Durabolin refers to progestins, and accordingly is much less androgenic than testosterone. Testosterone in the body is converted into a powerful androgen dihydrotestosterone due to which the majority of side effects occur, and Deca-Durabolin is reverse converted to a weak androgen dihydronandrolon with almost no side effects. But because of the small amount of androgens in the blood, the athlete can feel a decrease in libido. Also, because of the effect on progesterone receptors, sexual attraction is even weaker.
