Masteron: Benefits & Side Effects of this steroid

Introduction to Masteron

Masteron is branded drostanolone propionate. It is an androgenic-anabolic steroid or AAS, also called dromostanolone propionate. There are other branded versions of the generic steroid such as Masteril and Drolban. Drostanolone propionate or dromostanolone propionate is used in a few treatments but Masteron is used solely for supplementation.


History of Masteron

The oil-based steroid was first administered through intramuscular injection. Syntex developed drostanolone propionate in 1970 and subsequently introduced it, nearly eleven years after it was described for the first time. The steroid was then known as Masteril. It was also marketed as Metormon. For more than twenty years, the steroid was used in different types of therapeutic treatments. It was used as a medicine to provide relief to breast cancer patients. It is no longer used in treatment for breast cancer. Syntex does not manufacture the generic or the branded version of the steroid anymore. The steroid is not used as medicine or a drug today. It is mostly sold as asteroid. Masteron is a supplement for bodybuilders, powerlifters, athletes, sportspersons and fitness enthusiasts.

There are two variants of Masteron. One is Masteron enanthate and the other is Masteron propionate. One of the reasons why drostanolone propionate ceased to be used in different treatments and for various purposes is its short half-life. Since the method of administering it was an intramuscular injection, one could not be given a dose too frequently. Masteron enanthate is a different anti-estrogenic steroid than drostanolone propionate. It is referred to as mast or masto by some. It has a much longer half-life than drostanolone propionate. Masteron enanthate has a half life of six days. Drostanolone propionate has a half-life of two days. It has also been found that Masteron Enanthate is much more effective than drostanolone propionate.

Masteron is classified as an anti-estrogenic steroid. This is because of the ability of the androgenic-anabolic steroid to resist aromatization. Many androgenic-anabolic steroids get converted to the female sex hormone estrogen. This is called aromatization as it is caused or facilitated by aromatase enzymes. Masteron can actually inhibit these aromatase enzymes and block the receptors. This prevents conversions of testosterone to estrogen. The body then has more testosterone available that can be put to good use through workouts.

Benefits of Masteron

The most immediate effect and hence the benefit of Masteron is it’s freeing up more testosterone. The male sex hormone has a more multifaceted role than just influencing libido. Testosterone regulates energy. Men who have more available testosterone have surplus energy and are capable of performing much better, not just on the bed but also at the gym. Testosterone contributes to overall strength and also endurance in specific muscles. Testosterone regulates a few other bodily functions in men. From hair growth to the condition of the skin, testosterone is one of the most important hormones in men and ensuring there is enough of it for the body to use is a valuable benefit of Masteron.

Masteron is a testosterone booster in that sense and also a performance enhancement supplement. It can increase appetite. It also increases the metabolic rate. This helps in using the available calories for energy. Better metabolism leads to effective absorption of all available nutrients. This contributes to muscle growth. Since metabolism and appetite are high, Masteron is able to prevent weight or fat gain. Instead, it helps with developing lean mass. The effects on appetite and metabolism are not as much as the impact on testosterone but users will feel the difference. There is no need to increase the dose or prolong the cycle to keep experiencing the benefits. A time-bound and controlled use is sufficient to get the expected results.

Masteron benefits are realizable only when a user works out every day or at least five days a week. Those who do not work out will not experience many changes. They will feel more energetic and the sufficient availability of testosterone will improve their sex life but lean mass growth or developing a well-sculpted physique will not happen. Masteron is most effective during the cutting cycle. It can be used while bulking up but mostly when stacked with another supplement or androgenic-anabolic steroid. Masteron makes muscles feel stronger and firmer. In the cutting phase, Masteron can help muscles develop the desired contours and be more prominently sculpted.

The supplement does not cause fat gain. It has no effect on weight. However, people do lose weight during the cutting cycle and Masteron can facilitate that to an extent by letting the excess fat to be eliminated. Despite the impact on metabolism, appetite and fat loss, the latter being in the cutting phase, Masteron is not a weight loss supplement or fat-burning steroid. Masteron prevents water retention which is necessary during the cutting phase. Water retention in tissues leads to bloating, which prevents the muscles from taking the ideal shape or form.

Side Effects of Masteron

Masteron has a few side effects. It can raise blood pressure. This is a transient effect but it can be discomforting for those who already have high blood pressure. Some users might develop male boobs, a condition called gynecomastia. This is also a temporary problem. It is more common in men who have a history of gynecomastia. Bodybuilders or fitness enthusiasts who have been obese in the past or had issues with weight management usually have more fatty tissues in their chests. The breast tissues in such men can swell up, leading to a visible enlargement. The condition is not harmful in any way and effective exercise can easily counter such a development.

Men who have overactive sebaceous glands and oily skin may have acne. Very few men experience hair loss, that too temporary and only if they have a history of male pattern baldness or other hair and scalp problems in the genes. None of these side effects are strong enough to be discomforting or painful. They are all largely subtle and they subside as users progress through the course. It is possible for Masteron to interact with over the counter and prescription drugs. Those who are currently on medication should exercise caution. There can be side effects, not caused by Masteron but due to its interaction with other drugs.

Masteron Ingredients and Dosage

Masteron may contain drostanolone enanthate, drostanolone propionate or dromostanolone propionate. The dose for the latter in the case of intramuscular injection is up to 500mg per week.

The course is usually six up to ten weeks, mostly influenced or determined by the length of the cutting cycle.

Customer Reviews of Masteron

Masteron has been well received by users. It is indeed effective during the cutting phase. Some users have stacked it with other supplements during the bulking cycle too but have experienced varying results. Bulking up requires water retention. Masteron does not help with this and hence is not ideal for the bulking phase. Many users have reported experiencing significant surges in libido. This is not unusual or even unexpected. The availability of testosterone will drive libido up.


Masteron is one of the more popular and effective androgenic-anabolic steroids for cutting. Overdosing should be strictly avoided. The course should not be prolonged unnecessarily.
