Methenolone also referred to as Primobolan is an Anabolic Steroid which is available in both oral and injectable form. The oral form contains an acetate ester which allows it to be absorbed by the body without being destroyed before being absorbed into the bloodstream, the injectable version includes an enanthate ester. The oral version is one of the only oral Steroids out there that is not a C17-alpha alkylated which means it has not been altered to bypass the liver, C17-alpha alkylated Steroids have been known to put the liver under severe strain when used in large dosages or for long periods of time. Not being a C17-alpha alkylated Steroid also means more of the Steroid is broken down before being absorbed, this makes the depot version of the Steroid far more effective and popular, especially when considering the price tag.

This Anabolic Steroid is a mild anabolic as well as a mild androgenic which makes it a lot safer to use than other Steroids out there. Being a mild androgenic also means this steroid doesn’t have many side effects and most users see little to no side effects while using this steroid, this also makes it a popular choice for females as highly androgenic steroids can cause severe masculine side effects in females.

This Steroid was first released in 1962 by a company called Squibb. Squibb released both the oral and injectable version of Primobolan which were referred to as Nibal and Nibal Depot respectively. However, both these products were not available for very long and soon were taken off the market. In the 1960’s Schering obtained the rights to the Metholone hormone and produced it under the trade name Primobolan and has since been a popular Anabolic Steroid.

Primobolan has been used to treat muscle wasting, weight loss, and other medical conditions. However today it is mostly used by bodybuilders and athletes for its muscle and strength building properties.

Methenolone is a steroid derived from DHT (dihydrotestosterone), meaning it contains some of the same properties as DHT. For example, Primobolan does not aromatize, this means it does not convert to estrogen. Which is why many athletes choose to use it as the gains would then be lean muscle mass and no water retention which is a common side effect of steroids which do convert to estrogen. Being a Steroid which does not convert to Estrogen, Primobolan is one of the more popular choices for users looking to cut fat and want to achieve a “dry look.”

This Anabolic Steroid has many pros, but one huge problem is how much it costs. Along with Anavar, Primobolan is one of the most expensive Steroids available and due to high doses being needed to achieve good results, adding Primobolan to a cycle can be extremely expensive.

Side Effects

Although mild there are still possible side effects that can occur from using this Steroid. Acne, accelerated hair loss, high blood pressure and aggression are all possible although quite rare. Products such as Finasteride can be used to combat hair loss.

Primobolan Dosages

As Mentioned this is a mild Anabolic Steroid and higher dosages are usually required amongst males to achieve decent results. For Males a minimum of 200 to 400mgs of Methenolone Enanthate is needed to see results, however many athletes choose to use upwards of 1000mg a week to help build a good amount of quality muscle. Females need a much lower dosage than males and usually take between 50 and 100mg a week. Females often use the oral version as it is out of the system fast in case any unwanted side effects arise.
