Drostanolone Propionate is a dihydrotestosterone (DHT) derived anabolic steroid. Specifically, Masteron is the DHT hormone that has been structurally altered by the addition of a methyl group at the carbon 2 position, This protects the hormone from the metabolic breakdown by the 3-hydroxysteroid dehydrogenase enzyme, which is found in the skeletal muscle. It also greatly increases the hormone's anabolic nature. This simple structural change is all it takes to create Drostanolone, and from here the small/short Propionate ester is attached in order to control the hormone's release time. Drostanolone Enanthate can also be found through some underground labs, which does not have to be injected as frequently, but it is somewhat rare compared to the Propionate version. The majority of all Masteron on the market will be Drostanolone Propionate.




Drostanolone propionate is used primarily by athletes who need to retain strength while losing mass. It is beneficial to runners and athletes who must remain in a certain weight class

Drostanolone propionate can increase muscle hardness and density, giving an individual a more complete appearance when competing on stage

The most efficient way to benefit from Drostanolone Propionate is to add it to a cutting cycle. However, best results are seen on those who are very lean. This is why it should be used at the end of a cycle to help with prepping for a contest. Adding Drostanolone Propionate can help a bodybuilder to cut the last amounts of fat that seem to linger and be hard to get rid of with diet and workouts alone.

It will also make the physical appearance to be as great as possible. The anti-estrogenic will help the body to look natural and defined overall. However, if a person has too much fat and they aren’t in shape to compete in a bodybuilding competition, the effects from Drostanolone Propionate can be less than noticeable. For someone with more than 10% body fat, it is going to be hard to see the benefits of this compound.

For an athlete trying to get stronger but not bulk up, Drostanolone Propionate can be the best solution. An athlete using it though will need to be on a strict diet and stay within a given weight range. This is the only way for them to see an increase in strength, to have more muscle endurance, and to prevent weight gain.

Drostanolone Propionate is a bulking agent but not one with huge gains. This hormone is going to offer some gains similar to what a person can expect from Primobolan Depot. Neither is very strong even if you take the higher dose of it. Yet the gains can be moderate and they can be suited for someone who just needs some help with the last bit of fat or who needs help with improving strength. It can also be a supplement in a stack of steroids.

There are users who put Drostanolone Propionate in their bulking stack because they want the benefits of losing fat along with the anti -estrogenic properties. This helps them avoid gaining weight and fat during the off season. However, it is very possible to control body fat without it. Most will use high doses of testosterone during the off season, and they can benefit from the anti-estrogenic effects.

Progesterone activity is common with Nandrolone compounds. Adding Dinabol or Anadrol though and the amount of estrogenic activity can skyrocket. Drostanolone Propionate can help reduce it, but don’t count on it to be strong enough to fully combat the estrogenic activity.


Possible Side Effects:


For the most part Drostanolone Propionate, is a friendly anabolic steroid. The side effects that can happen are general mild. Most men find it to be quite tolerable and don’t have any side effects with it. Females are discouraged from using it at the right of virilization can be very high. They can be managed but women do need to have a very strategic plan for using it.


It is possible for androgenic side effects to occur with the use of Drostanolone Propionate. They can include:


Hair loss

Unwanted body hair

Some people are more sensitive to this than others. Often, there is a genetic issue such as male pattern baldness that can make a user of Drostanolone Propionate more likely to experience such androgenic side effects. Drostanolone Propionate isn’t metabolized by the 5-alpha reductase enzyme either so there is no reduction of DHT and nothing to inhabit. Taking Finasteride and other 5-alpah reductase inhibitors significantly increases the risk of androgenic side effects with tis compound.

Women are vulnerable to virilization with this product. The side effects include:

Deepening of the voice

Enlarged clitoris

Unwanted body hair

Such side effects often occur for women who used this product to fight breast cancer, but it was due to the high dose needed to fight it. Using Drostanolone Propionate at a very low dose may be able to help women get the performance enhancement they want without the side effects. Immediate top taking it if the symptoms develop or there is the risk of them becoming permanent.


It is important to test your cholesterol levels before, during, and after a cycle including Drostanolone Propionate. This compound can cause the good cholesterol to be reduced while allowing the bad cholesterol to increase. While the risk isn’t as high as it would be with an oral anabolic steroid, you can’t ignore the risk.

There is also a risk of the blood pressure increasing to a dangerous level so you must monitor that as well while taking it. Eat a well-balanced diet that is low in sugar and low in saturated fats. Eat a diet with plenty of omega fatty acids. Make sure you keep up your routine of cardio workouts several times per week.


Drostanolone Propionate won’t aromatize and it doesn’t carry proestin. Therefore, you don’t have to worry about any estrogenic side effects with this steroid. Many use it because they don’t want to deal with water retention or Gynecomastia which can occur with other compounds. You don’t have to worry about adding another item to the stack in order to fight the estrogenic effects either. However, you may need to depending on your overall stack and what is in it.
