Provibolic (Mesterolone) is an oral anabolic steroid derived from dihydrotestosterone.
Provibolic (Mesterolone) is highly favored by athletes for its ability to increase androgen levels when dieting or preparing for a contest, and as an anti-estrogen due to its intrinsic ability to antagonize the aromatase enzyme.
Estrogenic Side Effects
Provibolic (Mesterolone) is not aromatized by the body, and is not measurably estrogenic. An anti-estrogen is not necessary when using this steroid, as the drug is unlikely to induce gynecomastia, water retention, or other estrogen-related side effects.
Androgenic Side Effects
Provibolic (Mesterolone) is classified as an androgenic steroid. Androgenic side effects are common with this substance, especially with higher doses. This may include bouts of oily skin, acne, and body/facial hair growth.
Anabolic/androgenic steroids may also aggravate male pattern hair loss.
Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement.
