You may conclude the benefits are obvious in that case if the rumors are true.



In this article, we attempt to provide you with all you should know before using this drug. Learn about its pros, cons, and usage.

What is Primobolan?

Primobolan is a popular trade name of the anabolic and androgen steroid methenolone. This compound is familiar to many experienced steroid users, who often call it “Primo.” It has a mild nature that makes it more tolerable to use compared to many other steroids.

Methenolone is a synthetic androstane steroid derived from dihydrotestosterone (DHT). It is a structurally altered form of the testosterone by-product, with the addition of a double bond at carbon atoms 1 and 2 of the latter. The substance also has an extra 1-methyl group for protection against metabolism and breakdown in the liver.

Primobolan shares several qualities with its parent substance. A major quality is that the aromatase enzyme does not aromatize it into the female hormone estrogen. This makes it less likely to produce estrogenic side effects, such as fluid retention and gynecomastia.

This drug is often compared to another popular anabolic steroid Anavar. But Primobolan is actually milder than Anavar. It has an androgenic rating between 44 and 57 and an anabolic rating of 88. Both ratings are even lower than those of testosterone.

Primobolan was originally released by Squibb into the U.S. market in 1962. The injectable form known as methenolone enanthate was the first compound available on the market for commercial use. An oral form, methenolone acetate, later emerged in the same year. The company sold it under the brand name Nibal.

The injectable variant is now sold under the brand name Primobolan Depot. The oral form is usually simply referred to as Primobolan.
