Mastrolone is a popular steroid for competitive bodybuilders.

The great popularity of this injectable steroid in bodybuilder circles is due to extraordinary characteristics.

Mastrolone is a synthetic derivative of dihydrotestosterone.

This means that Mastrolone cannot aromatize in any dosage and therefore cannot be converted into estrogen.

As Mastrolone is a primarily androgenic steroid, the athlete can increase their androgen level without also risking an increase in their estrogen level.

This results in a dramatically improved hardness and sharpness of the muscles.

A distinction needs to be made here, however, because Mastrolone does not automatically improve muscle quality for everyone.

A prerequisite is that the athlete must already have a very low fat level.

In this case Mastrolone can then be the decisive factor to make a good qualitative one.

For this purpose Mastrolone is often used only during the last four weeks before a competition, for the home stretch.

Mastrolone is particularly effective in combination with steroids such as Winstrol, Parabolan, Primobolan, Oxandrolone and testosterone propionate. The usual dose taken by athletes is around 100 mg three times a week.

Since the substance drostanolone propionate is quickly broken down in the body, frequent and regular injections are necessary.

This fact makes Mastrolone an interesting steroid even where doping controls have to be passed by a negative urinalysis.

Since the substance drostanolone propionate does not stay in the body very long in a sufficient, detectable amount, athletes inject the compound with great success up to two weeks before a test. However, as it also has anabolic characteristics and thus helps in building up a high qualitative muscle system, the use of Mastrolone is not only limited to the preparation phase for a competition.

Athletes who want to avoid water retention and who easily have a problem with high estrogen levels also appreciate Mastrolone.

Also in this case usually one ampoule (100 mg) is injected every other day.

In combination with Primobolan, Winstrol or testosterone propionate without enormous strength and weight gain can be achieved, only high quality and long lasting results.

Although women do not use Mastrolone

Very often, some national competitors and international female athletes only take it before a championship.

Dosages are normally seen at 100mg every 4-5 days.

Mastrolone is not hepatotoxic and liver damage is very unlikely.

High blood pressure and gynecomastia are not a problem since neither water nor salt retention occurs and therefore the estrogen level remains low.

The main problem is acne and accelerated hair loss because dihydrotestosterone is very sensitive to androgen receptors in the skin and, in particular, those on the scalp.

Mastrolone in most cases is not administered in large doses repeatedly and the duration of a course, at the same time, is limited to a few weeks, the results on athletes are usually very good.
