Drostanolone Propionate Description

Drostanolone Propionate is a powerful anabolic/androgenic steroid derived from DHT that was designed to fight certain forms of breast cancer. It is used by bodybuilders as a bulking and cutting agent, as well as an ancillary drug to combat estrogenic side effects like water-retention. Its toxicity to the liver is very low, although side effects such as acne, hair loss and prostrate enlargement are common.


Masteron is an injectable preparation containing the steroid drostanolone propionate. Drostanolone is a derivative of dihydrotestosterone, most specifically 2alpha-methyldihydrotestosterone. As a result, the structure of this steroid is that of a moderate anabolic/potent androgen which does not aromatize to estrogen.


Water retention and gynecomastia therefore do not come into play with this drug. Masteron may in fact exhibit anti-estrogenic activity in the body, competing with other substrates for binding to aromatase. This would reduce the conversion rate of other steroids, Masteron acting in the same way as the oral steroid Proviron.


Drostanolone Propionate Usage

has the potential (as an anabolic androgenic steroid), to:

  1. Enhance strength
  2. Improve endurance
  3. Provide greater viscosity or hard appearance of muscle

It is not known to provide dramatic gains in lean muscle mass or to prevent cachexia or muscle wasting.


Drostanolone Propionate Dosage

As mentioned, taken by itself and at the Drostanolone propionate 100 mg dosage, side effects are not typical. However, the higher the dosage, the increased risk of developing side effects.

  • On average, an experienced bodybuilder can inject anywhere from 100 mg to 400 mg of Drostanolone propionate strength solution per week. That breaks down to a 100 mg dose of Drostanolone propionate every other day.
  • Some bodybuilders decrease dosage to 50 mg daily to prevent side effects – with varying Masteron cycle results.
  • Women using Drostanolone are recommended to stick to a 50 mg per week dosage to reduce the potential for virilism. The 50 mg a week dosage is also divided into smaller injections every two to three days.
