Pharmacokinetics and Indications: Masteron is an anabolic/androgenic steroid. It is known to be highly androgenic and mildly anabolic. It is incapable of aromatization and has similar properties to dihydrotestosterone. It has been successfully used as a breast cancer drug but because of the high risk of virilization safer options are prescribed. Masteron is not clinically used for weight gain (as is common with most steroids), so this makes it a very unique steroid from that perspective. Unfortunately, much of the information on Masteron available in medical journals doesnt focus on weight or strength gain or even fat loss, for those reasons.Possible Side Effects: Since estrogen is not an issue, side effects are generally mild with this steroid. As discussed earlier, gynecomastia, water retention, and high blood pressure are 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.Effective DoseBeginners : not recommended Hobby : 50 - 100 mg / every other day Professionals : 100 mg / day or every other day Women : 100 - 150 mg / weekUse for : 4 - 12 weeks
