Mastorop (Drostanolone Propionate) is an injectable anabolic steroid derived from dihydrotestosterone (DHT).
Mastorop (Drostanolone Propionate) is highly favored by athletes for its ability to produce solid increases in lean muscle mass and strength, which are usually accompanied by reductions in body fat level and minimal side effects.
Estrogenic Side Effects
Mastorop (Drostanolone Propionate) is not aromatized by the body, and is not measurably estrogenic. An anti-estrogen is not necessary when using this steroid, as gynecomastia is very rare even among sensitive individuals.
Mastorop (Drostanolone Propionate) as a non-aromatizable DHT derivative, may impart an anti-estrogenic effect, the drug competing with other (aromatizable) substrates for binding to the aromatase enzyme.
Androgenic Side Effects
Although classified as an anabolic steroid, androgenic side effects are still 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.
