Methenolone Acetate is primarily an oral steroid, Schering did manufacture it as an injectable at one time. However, the injectable version was discontinued in 1993. Any injectable Acetate form will strictly be found through underground labs, but even then it will be rare. Most underground labs that manufacture the Acetate version will do so in oral form. Many, however, simply stick the large injectable Depot version.

Primobolan is considered one of the safest anabolic steroids on the market and it carries an excellent safety rating to back this claim. In fact, this steroid has been used successfully to treat underweight children and premature infants without damage. It is also prescribed for osteoporosis and sarcopenia. However, the primary purpose of Primobolan is treating muscle wasting diseases and prolonged exposure to corticoid hormones. It has also proven to be extremely effective in treating malnutrition.

Playing an important role in therapeutic treatment plans, Primobolan is a very popular anabolic steroid among performance enhancing athletes. However, the injectable Depot version is far more popular as the oral version packs a much weaker punch. For bodybuilders, injectable Methenolone Acetate is the preferred form but a quality injectable Acetate version is very difficult to find. Further, the Methenolone hormone itself, while limited in oral form is one of the more commonly counterfeited anabolic steroids out there. It is also fairly expensive in many underground markets.

Methenolone is a derivative of dihydrotestosterone (DHT) or more specifically a structurally altered form of DHT. A double bond at carbon one and two is added to the DHT hormone, which in turn greatly increases the hormone’s anabolic nature. It also carries an added 1-methyl group that protects it from hepatic breakdown. The addition of the Acetate ester further protects it from hepatic metabolism.

As an oral steroid, Primobolan is one of the only oral steroids that is not a C17-alpha alkylated (C17-aa) steroid. Lacking the standard C17-aa structure, this also means oral Primobolan is not toxic to the liver. However, while this is a bonus, most will find oral Primobolan to be a relatively mild or even a week steroid compared to many others in a performance enhancing capacity. Men will not experience the same level of anabolic activity compared to many anabolic steroids. Make no mistake, Primobolan has its place in a performance capacity, but most men will find the Depot version to be a better call. As for women, this mild nature is in part what makes it a fantastic choice. Methenolone hormone has been shown to significantly enhance the immune system. In fact, it has been successfully used in treating those with AIDS. For such an individual, he not only gets an immune boost but direct protection from what is a muscle wasting disease. This same immune boost will greatly benefit the performance enhancing athlete during the cutting phase.
