The main side effects of Masteron: hair loss, acne, nervousness and aggressiveness, enlargement of the prostate, symptoms of virilization in women. The drug does not cause swelling and liver damage.

Unlike Testosterone, Masteron is not a universal anabolic agent. It is mainly used for solving specific tasks. The drug has a positive effect on overall health: it allows you work out harder even with the minimum caloric intake. Masteron helps the athlete bring the body into optimal shape before competitions.

As for beginners, they should not start with this steroid (Oxandrolone is better for beginners). Powerlifters may take Turinabol or Deca instead of Masteron.

Masteron (Drostanolone Propionate) benefits

In the medical field, Masteron is sometimes used as a drug for the treatment of breast cancer in women. However, the therapy is associated with high probability of virilization in women. As of today, Masteron is successfully used in male athletes to increase power due to fat burning and diuretic effects.

Masteron has won recognition among bodybuilders as an exceptional drug for building quality muscles and removing excess fluid from the body. Masteron provides qualitative growth of muscles and improves physical performance. This is one of the most popular steroid agents among athletes.

Masteron (Drostanolone Propionate) effects:

  • Without a doubt, this drug is most effective during the cutting phase. However, even more noticeable results can be achieved if you follow a strict diet. Therefore, the drug is used in the final stage, when the percentage of body fat is already small enough (less than 10%).
  • You will get extremely hard muscles and significant changes in muscle fiber size. But do not forget that Masteron helps achieve such results only in case of low body fat.
  • Masteron will help increase endurance without undesirable weight gain.
  • The drug does not aromatize, does not cause side effects associated with estrogen.
  • It does not cause gynecomastia or fluid retention.
  • Masteron is not a hepatotoxic anabolic steroid. Thus, it will not cause damage to the liver.

Masteron (Drostanolone Propionate): side effects and contraindications

Contrary to popular belief, Masteron is an anti-estrogenic drug only partially. The drug really lowers estrogen levels in the blood, but in fact, this can also be considered a side effect.

Masteron is a derivative of DHT. Thus, it can’t be converted into estrogen. In fact, its anti-estrogenic activity is similar to Proviron.

As already mentioned, Masteron has no estrogenic effects. So side effects such as water retention, high blood pressure, and gynecomastia won’t be a problem when using this steroid.

Drostanolone Propionate is available only as an injectable steroid, so it is not toxic to the liver.

Masteron is a strong androgen that can cause oily skin, acne, hair growth on the face and body and hair loss. For this reason, those athletes who have a predisposition to baldness should be careful with this steroid. Like most steroids, Masteron suppresses natural testosterone production. Therefore, a proper post cycle therapy is always necessary.

Practice shows that this anabolic steroid is considered one of the safest agents for the sport. In general, Masteron therapy can lead to growth of excess body hair and hair loss. Despite the fact that there are female athletes who use Masteron as precompetitive preparation, it is very dangerous due to the high risk of virilization symptoms. Those women who dared to use Masteron must not exceed a dosage of 50 mg per week. Anyway, women should take this drug with extreme caution.

Masteron Cycle (Drostanolone Propionate) Doses

Masteron cycle usually lasts from 6 to 10 weeks, or sometimes longer (8-12 weeks). At the same time, long cycle is better for weight gain, while short cycle – for burning fat.

Drostanolone Propionate can be used in combination with other steroids, as well as alone (the dose is usually higher). Men are advised to use from 300 to 500 mg per week (every other day or every third day), as the active substance works up to three days. Due to the high probability of virilization, women are advised not to exceed the dose of 25-50 mg/day. Use the injection once every three days.

Steroid dosages are in the range from 200 to 600 mg. Experienced athletes may take 1000 mg per week, while 600 mg will be quite enough for ordinary athletes. Beginners should start with lower doses.

Drostanolone Propionate does not aromatize. Therefore, there is no need to take anti-estrogen drugs with Masteron. This anabolic agent is well combined with Winstrol (50-100 mg daily or every other day). The drug produces good results in combination with synthetic derivatives of Testosterone. For example, the combination of Boldenone with Masteron is used to build muscle of the highest quality. However, one must note that this combination may cause an increased appetite in some athletes.

Masteron (Drostanolone Propionate) cycle: solo and PCT

Duration of the cycle – 6-10 weeks; the optimal dose – 400-500 mg per week (3 times a week). Higher dose does not lead to a better result, but increases the risk of side effects. As for beginners, they can try Masteron solo (50 mg every other day) or combine with Methandrostenolone (30 mg daily) for six weeks.

Masteron belongs to mild anabolic steroids. Therefore, one can begin the PCT within a week after the last injection of the drug.

Masteron (Drostanolone Propionate) cycle: combined courses and PCT

One can obtain excellent results while using from 300 to 400 mg of Masteron combined with 400 mg of Testosterone Propionate (dose per week), and 300 mg of Trenbolone Acetate (weekly). All steroids should be taken every second day for eight weeks.

Examples of combined courses:

For the cutting phase: Turinabol (40 mg daily), Testosterone and Masteron (100 mg every other day). Duration – 6-8 weeks.

Mass building program (for beginners): 50-100 mg of Masteron + 30-40 mg of Dianabol (Methandrostenolone) daily. Duration – 6 weeks.

Mass building program (for experienced athletes): Stage 1 (1-8 weeks): 300 mg of Drostanolone + 500 mg of Testosterone Enanthate (per week). Stage 2 (9-10 weeks): 50 mg of Drostanolone + 100 mg of Testosterone (every other day).

It is recommended to use Clomid (less toxic analogue of Tamoxifen) after the cycle. The dosage depends on the severity of the cycle: you can start with 50-100 mg and gradually reduce the dose. As for PCT, it can be started within a week after the last injection.

It is important to remember about nutrition and training prior to the beginning of the cycle. The proper post cycle therapy is even more important than the cycle itself. If you think the effect is insufficient, then you can repeat the cycle after some time.


Masteron is mainly used to gain muscle hardness. However, this is one of the best steroids for combination with other anabolic agents.

Masteron has very few side effects, most of which are associated with its high androgenic activity. In general, symptoms such as swelling and gynecomastia never occur while taking Masteron. Also, the drug does not lead to high blood pressure, which makes it safe for the cardiovascular system. All in all, this is an exceptional steroid that works perfectly in synergy with other anabolic steroids.
