Info: Drostanolone Propionate is an anabolic androgenic steroid that first hit the market around 1970 under the trade name Masteron manufactured by Syntex.

Drostanolone carries relatively normal anabolic and androgenic ratings; however, these ratings are something missing. It’s important to remember DHT, the basis of Drostanolone, is five times more androgenic than testosterone with a much stronger binding affinity to the androgen receptor. This again promotes a harder look and can also enhance fat loss.

Drostanolone Propionate is the propionate salt form of dromostanolone, a synthetic anabolic steroid related to dihydrotestosterone that has antiestrogenic effects. Dromostanolone inhibits the growth of estrogen receptor-presenting breast cancers; its virilizing effects limit its clinical usefulness. It would also become popular cutting steroid among bodybuilders, which is where Drostonolone is currently most commonly found.


Drostanolone Propionate profile

  • Androgenic index – 25
  • Anabolic index -62
  • Estrogen level – Very low
  • Progestational - Low
  • Toxicity for the liver - Low



The drug has the property to assure positive nitrogen balance in humans and promotes protein synthesis. It has the goal to offer increased strength while keeping body weight and lose body fat.
  • Improves endurance
  • Average increases in strength
  • Faster regeneration
  • Burn 5-7% of fat during cycle
  • No water retention
  • Muscle build-up
  • Increases in collagen synthesis and bone mineral content.
  • Increases in levels of IGF-1 and MGF hormones (which also promote muscle growth)
  • Increases haemoglobin (red blood cell count)
  • Anti-catabolic effect on muscle tissues by way of acting as an anti-glucocorticoid

Without question, the effects of Masteron will be displayed in the most efficient way during a cutting cycle.


Dose range and duration of use

Common cycle length is 6-12 weeks
Hobby: 400-500mg/week
Professional Range: 500-600mg /week
Women: 50-100/weekly
Half-life: 2-3 days
Detection time: 3 weeks


Side effects

Masteron does not aromatize and it does not carry any progestin nature making estrogenic side effects impossible with this steroid. This means gynecomastia, bloating and water retention will not be concerns.

Due to its androgenic nature, Masteron can produce virilization symptoms in women. Virilization symptoms can include body hair growth, a deepening of the vocal chords and clitoral enlargement.

Masteron will significantly suppress natural testosterone production making exogenous testosterone therapy important when using this steroid. Failure to include exogenous testosterone will lead most men to a low testosterone condition, which not only comes with numerous possible symptoms but is also extremely unhealthy.


After cycle therapy

After your last injection, the post cycle therapy starts, approximately 9-14 days

Following the end of any cycle, a thorough and proper Post Cycle Therapy is always necessary, where Testosterone stimulating ancillary compounds such as Nolvadex and/or HCG should be utilized in order to facilitate the normalization of the HPTA (Hypothalamus-Pituitary-Testes-Axis) and endogenous Testosterone production as quickly as possible.

Drostanolone propionate itself does not aromatize into Estrogen and thus does not require anti-estrogen protection throughout the cycle. However it is most commonly used in combination with a testosterone (which does require protection).
