Since estrogen is not an issue, side effects are generally mild with this steroid. As discussed earlier, gynecomastia, water retention, and high blood pressureare not a problem. Masteron is also not liver toxic, so there is little concern stress will be placed on this organ, even during longer cycles. The only real side effects would be from the basic androgenic properties of dihydrotestosterone. These includes oily skin, acne, body/facial hair growth, aggression and accelerated hair loss. Since this compound is already a synthetic DHT, Proscar would have no impact on the level of androgenic effects. Men with a receding hairline or those with a predisposition for baldness may therefore wish to stay away from Masteron completely, as the potent androgenic effect of this steroid can easily accelerate this condition.
