Product Description


Propionate androgen (BAN) (brand name Masteron, Drolban, others), is also known as propanoxacin (USAN), and 2α-methyl-4,5α-dihydrotestosterone, is a synthetic anabolic androgen steroid (AAS) and propionate. It does not have aromatic effects and has similar properties to dihydrotestosterone (DHT). Has been successfully used to treat breast cancer, but because of the high risk of the virus, it is usually changed to a better tolerant choice. Propionate androstenol ketone is not orally active and must be replaced by intramuscular injection.

Propionate androstosterone ketone is an anabolic androgen steroid, which for the first time in 1970 to Syntax produced the name of Masteron to enter the market. However, the compound was actually developed by Syntex in 1959 and used with hydroxymethyl (Anadrol), but was not released until after Anadrol. Syntex will also provide licenses to Lilly under a number of other brand names (such as Masteril and Metormon) and Drolban under Syntext. However, Masteron is still the most well-known brand.

Test 600x as a therapeutic agent, Masteron in postmenopausal women with two decades of successful confrontation with advanced inoperable breast cancer. It will also be a popular cut steroid in bodybuilding, which is the most common place for Masteron. However, the Masteron brand is no longer available; in fact, almost all of the world's pharmaceutical brands have been discontinued. The compound is still approved by the US FDA, but is rarely used for breast cancer treatment, which is beneficial to other options. However, steroids are still very popular in the competitive bodybuilding cycle and are often considered the key to the preparation of the game.






Propionic acid androgen ketone is derived from metabolically steroid dihydrotestosterone (DHT). Specifically, Masteron is a DHT hormone that is structurally altered by the addition of methyl groups at the carbon2 position. This protects the hormone from metabolic breakdown of 3-hydroxy steroid dehydrogenase found in skeletal muscle. It also greatly increases the synthetic metabolic nature of hormones. This simple structural change is required to create Drostanolone, where the small / short propionate is attached to control the release time of the hormone. They can also be found in some underground laboratories androgen ketone butyrate, these underground laboratories do not need frequent injections, but compared with Propionate version, it is somewhat rare. The majority of all Masteron on the market will be prednisolone propionate.

On the basis of function, Masteron is known as one of the only synthetic estrogenic steroids with strong anti-estrogen properties. This steroid not only does not have estrogenic activity, but also acts as an antiestrogen in the body. That is why it is effective in treating breast cancer. In fact, the combination of Masteron and Nolvadex (tamoxifen citrate) has been shown to be more effective than chemotherapy in postmenopausal women for the treatment of ineffective breast cancer. It also makes it a generic steroid in bodybuilders because it can actually prohibit the use of antiestrogens in the right cycle. This will also be advantageous in the cutting stage due to the hardening effect that it can provide.

Adverse Effects

In many ways, Masteron is a fairly effective anabolic steroid. Masteron uses side effects absolutely, but most men will find this steroid highly tolerant. For women, this steroid can enhance viral symptoms, but we also find that the treatment can be done through the correct program. In order to understand the side effects of Masteron, we break it down into the respective categories and everything you need to know.


Masteron is not aromatic, and does not carry any progesterone properties, making the steroids cannot produce estrogen side effects. This means that men's breast development and water retention will not cause concern. This also means that high blood pressure, sometimes caused by excessive water retention, will not cause concern. Because of the use of this steroid, no anti-estrogen is required; as discussed, it can itself have an antiestrogen effect. However, depending on the specific cycle / accumulation performed, anti-estrogen may be required.


Side effects of Masteron can include side effects of androgenic properties. Androgen side effects may include acne, accelerating hair loss in men with baldness and body hair growth. Fortunately, this hormone has a moderate level of total androgen activity, although it is a direct derivative of the active androgen DHT. However, individual susceptibility will play a strong role in this steroid is well known and greatly enhances the sensitivity of male male baldness to far more than many synthetic metabolic steroids.

An important indication is that Drostanolone hormones are not metabolized by 5-alpha reductase. This is the enzyme responsible for reducing testosterone to dihydrotestosterone. In the case of Masteron, it is already DHT; there is no reduction. Because there is no reduction, no metabolism, nothing can be suppressed. This means that the androgen properties of Masteron are not strongly affected by 5-alpha reductase inhibitors such as finasteride.

Because of its androgenic, Masteron can produce sickness in women. Infection symptoms can include body hair growth, vocal and penis enlargement. Vitamin symptoms have been well documented in breast cancer treatment programs, but this is usually due to the high dose required for the treatment of this condition. In terms of performance, it should be possible to use such steroids with no associated symptoms and low doses. If the use and related symptoms begin to appear and stop using immediately, they will disappear. If the symptoms are ignored, they are likely to enter and become irreversible.


Masteron can have a significant effect on cholesterol. This may lead to increased LDL cholesterol, HDL cholesterol decreased the most intense. The overall effect on cholesterol is not as strong as in many oral steroids, particularly in C17-alpha alkylated steroids. However, the overall effect on cholesterol management will be stronger than Nandrolone compounds or testosterone hormones. Masteron is also likely to have a slight negative impact on blood pressure, but in most cases this will be a non-problem.

Due to the cholesterol effect of Drostanolone, the management of cholesterol is very important for this steroid. More important than the basic testosterone cycle or stacking, including the basic 19 - if you are already suffering from high cholesterol, then you should not use this synthetic metabolic steroid. This not only means a healthy diet, but also should contain a lot of omega fatty acids in the food, saturated fat and simple sugar are limited. Also suggest a lot of cardiovascular activity.


Masteron will significantly inhibit the production of natural testosterone, so that exogenous testosterone treatment in the use of the steroids is very important. Does not include exogenous testosterone can cause most men to reduce testosterone, which not only brings many possible symptoms, but also very unhealthy.

Since most of the masteron will be used in the cutting cycle, it is very common to use a large amount of testosterone because it can provide a high level of estrogenic activity. If this is the case, you will find that 100-200 mg of low-dose testosterone per week is sufficient to resist the inhibition and give the desired testosterone.

Once Masteron stops using, and all exogenous steroid hormones have cleared your system, natural testosterone production will start again. The previous level will not return to normal, it will take a few months time. Due to the slow recovery, it is often recommended to use post-circulation therapy (PCT) programs. This will speed up the recovery
