(Drostanolone Propionate) Masteron P


Under the brand name Masteron, which was produced by Syntex, drostanolone propionate, an anabolic androgenic steroid, first entered the market in the 1970s. Contrary to popular belief, the substance was created by Syntex in 1959 with Oxymetholone (Anadrol), but it wasn’t until much later that it was made available to the public. In addition to using Drolban under the license Syntex granted to Lilly, Syntex would also sell the drug under a variety of other brand names, including Masteril and Metormon. The most well-known brand, however, has always been Masteron. Masteron has had two decades of effectiveness as a therapeutic agent in treating postmenopausal women with advanced, inoperable breast cancer. Masteron would also gain popularity among bodybuilders, who currently use it most frequently, as a cutting steroid. Fewer and fewer people today use Masteron to assist in the treatment of breast cancer. As a result of the drug’s effects on the body’s hormonal systems, however, it has gained popularity among sportsmen and bodybuilders. One may imagine some of Masteron’s properties given that it is an anti-estrogen. The substance, which is generated from the hormone dihydrotestosterone (DHT), does not aromatize (also known as convert to estrogen) in the body. Estrogen can be produced through the aromatization of free testosterone, or testosterone that is easily used by the body. However, the original Masteron brand is no longer offered; in fact, almost all pharmaceutical brands have been withdrawn from the market. Although the U.S. FDA continues to authorize this substance, it is now rarely utilized in the treatment of breast cancer in favor of other alternatives. The steroid however remains incredibly common in competitive bodybuilding cycles and is frequently regarded as being necessary for contest preparation.


Dihydrotestosterone (DHT) is the source of the anabolic steroid drostanolone propionate. In particular, Masteron is the DHT hormone that has undergone structural modification through the addition of a methyl group at the carbon 2 position. This shields the hormone from being metabolically broken down by the enzyme 3-hydroxysteroid dehydrogenase, which is located in skeletal muscle. The hormone’s anabolic properties are also significantly enhanced. Drostanolone is produced by a straightforward structural modification, and the small/short Propionate ester is then added to this to regulate the hormone’s release time. Drostanolone Enanthate, which does not require as often injections but is less common than the propionate form, is also available through some underground labs. Drostanolone Propionate will make up the bulk of all Masteron that is now available. Functionally speaking, Masteron is well known for being one of the few anabolic steroids with potent anti-estrogenic characteristics. This steroid not only has no estrogenic properties, but it might also have the opposite effect and behave as an anti-estrogen. It has been successful in treating breast cancer because of this. In reality, studies have shown that chemotherapy is not nearly as successful as the combination of Masteron and Nolvadex (Tamoxifen Citrate) in treating postmenopausal women with incurable breast cancer. Since of this, it is also a well-liked steroid among bodybuilders because, when administered in the appropriate cycle, it may eliminate the requirement for an anti-estrogen. The hardening effects it can produce will also be helpful during the cutting step. Although Masteron has relatively modest anabolic and androgenic scores, these rates may be deceptive. It’s critical to keep in mind that the active ingredient in Masteron, DHT, is five times more androgenic than testosterone and has a far higher affinity for the androgen receptor. Once more, this encourages a tougher appearance and may aid in fat loss. Most anabolic steroids are known for speeding up metabolism, but potent androgens often directly encourage lipolysis. Masteron is not a popular anabolic for increasing increases in lean muscle mass. It has never been therapeutically utilized to prevent muscle atrophy, and performance athletes nearly always include it in their cutting regimens. However, it can encourage big increases in strength, which might be advantageous to an athlete who isn’t necessarily seeking raw mass.


We have divided the Masteron side effects into their various categories and provided all the information you require so that you can comprehend them.

  • Estrogenic:Masteron can’t have estrogenic adverse effects because it does not aromatize and has no progestin nature. Water retention and gynecomastia won’t be issues as a result. Additionally, it eliminates the risk of elevated blood pressure, which can occasionally be brought on by too much water retention. This steroid’s use eliminates the need for an anti-estrogen because, as previously mentioned, it can act as an anti-estrogen. A contraceptive pill, however, can be required depending on the particular cycle or stack that is used.
  • Androgenic: Androgenic side effects are one possibility for Masteron. Androgenic side effects might include acne, faster hair loss in people prone to male pattern baldness, and body hair growth. Fortunately, despite being a direct descendant of the strong androgen DHT, this hormone has a moderate amount of overall androgenic activity. This steroid is well-known for significantly worsening male pattern baldness in sensitive men more than many anabolic steroids, albeit individual sensitivity will play a large impact.
  • Cardiovascular:Cholesterol may be significantly impacted by Masteron. This may lead to a rise in LDL cholesterol as well as a fall in HDL cholesterol, with the latter bearing the greatest risk. The overall impact on cholesterol won’t be as significant as it is with many oral steroids, particularly those that are C17-alpha alkylated. The overall impact on cholesterol management will be greater than that of testosterone or Nandrolone molecules, though. The little negative effect that Masteron might have on blood pressure is also conceivable, but most people won’t be concerned about it.
  • Testosterone:When utilizing this steroid, exogenous testosterone therapy is crucial because Masteron will dramatically reduce natural testosterone production. Most men will have low testosterone, which not only has a wide range of potential symptoms but is also quite harmful if exogenous testosterone is not included in their diet. Due to the large levels of estrogenic activity that testosterone can produce, most people who use Masteron in a cutting cycle frequently don’t want to use a lot of it. If this is the case, a low dose of 100–200 mg of testosterone per week will be sufficient to counteract suppression and provide you with the necessary testosterone.
  • Hepatotoxicity:Masteron does not stress or harm the liver because it is not a hepatotoxic anabolic androgenic steroid.


If you choose to begin using Masteron for your workouts, there are a lot of benefits you might encounter. The most well-known and sought-after advantages of Masteron include those mentioned above.

  • Development and hardness of muscles. The way Masteron increases your muscles’ firmness is one of its most obvious effects. For athletes and bodybuilders looking to improve their physique, this is perfect. By boosting muscular density, it is also known to give people a “filled-out” appearance. Despite this, Masteron is not well known for being as effective in this aspect as other more potent steroids, like Tren.
  • Many claims that using Masteron increases their energy levels while at the gym or home. Additionally, it aids in accelerating metabolism and increases cellular energy production.
  • It aids in cutting. Masteron may be a wonderful steroid for you if your goals include weight loss and a more defined physique. A lot of folks say it’s better at aiding in weight loss than it is at actually bulking up.


Smaller doses of drostanolone propionate—50 to 150 mg/ml—are typically used. Because the body consumes, breaks down, and excretes this version more quickly than the previous one, it has a shorter half-life. You must be sure to administer another injection at least once every two days as a result.


Masteron is regarded as a rather weak anabolic steroid in some sectors that deal with performance enhancement. This is partly because the steroid has weak mass-promotional powers, and many people mistakenly believe that quality steroids have strong mass-promotional properties. Some people also tend to forget that even high-quality steroids won’t do much good unless you’re slim. This often results in people thinking incorrectly, which tends to give them a distorted impression of Masteron. This anabolic steroid is really helpful, but to reap the benefits it can offer, you must be aware of both its intended use and its advantages.
