Primobolan is the trade name for the anabolic steroid Methenolone (also written as Metenolone). It is available in both an injectable oil-based format, as well as an oral form. Injectable Primobolan is known as Methenolone Enanthate, and the oral format is known as Methenolone Acetate. It is a very well-known and popular anabolic steroid due to its very mild nature as both an anabolic and an androgenic compound. It is often compared to Anavar, a similar anabolic steroid but the difference between the two is very distinct – Anavar possesses a far greater anabolic strength rating than Primo.
Primobolan is actually a very weak anabolic steroid, weaker in fact, than Testosterone itself. It possesses an anabolic rating of 88, while Testosterone’s anabolic strength rating is 100 – this demonstrates Primobolan’s fairly weak strength in terms of anabolic capabilities. The same holds true for its androgenic strength rating, which is approximately 44 – 57 in comparison with Testosterone’s androgenic rating of 100. This weaker androgenic strength rating is actually very favorable, but its weak anabolic strength capability leaves it as a far less desired anabolic steroid where the majority of individuals considering its use often opt for Anavar instead. It is instead utilized as primarily a compound in cutting cycles, whereby the preservation of muscle mass is the goal instead of the addition of new mass. Along this same line of logic, this anabolic is almost never utilized in bulking cycles due to its lack in anabolic strength.
Primobolan cycles are commonly in the form of fat loss and/or cutting cycles. It is almost never used as a bulking or mass-gaining agent, and most of its use is in the form of a pre-contest drug in the final weeks leading up to a competition show or photo shoot. It is typically cycled with other compounds that hold similar qualities, properties, and half-lives. Many bodybuilders often stack Primobolan with Testosterone Propionate (or Testosterone Enanthate) and use it for the first 8 weeks of a cycle in order to assist in the retention of muscle mass during periods of low caloric intake.
Other bodybuilders will perform oral Primobolan cycles stacked with compounds such as Testosterone Propionate and Trenbolone Acetate, as all of the compounds involved work synergistically especially where half-lives are concerned. Some may opt to use Primobolan (either the oral or injectable) with some form of Testosterone and Winstrol (Stanozolol), typically the injectable form if it is with the oral Primobolan. It is important to remember not to utilize two different oral compounds within the same cycle.

Primobolan dosage and administration depends heavily upon which form is being used: oral or injectable. Medical prescription Primobolan dosages outline 200mg as a first dosage, followed with 100mg every week for the complete duration of therapy. The medical condition being treated would determine what the actual full Primobolan dosage is. The range can be anywhere from 100mg every one or two weeks to 200mg every two to three weeks. Medical guidelines for oral Primobolan dosages call for 100 – 150mg per day for no longer than 6 – 8 weeks of consistent use.
The first thing to understand with Primobolan is that it is a DHT-derivative, meaning it is a modified form of DHT (Dihydrotestosterone). As such, it carries with it many similar properties and characteristics, including the inability to convert (aromatize) into Estrogen at any dose used. This should certainly be a comforting fact to most individuals who are concerned about Estrogenic side effects, such as bloating, gynecomastia, high blood pressure as a result of water retention, etc.
Although the oral format of Primobolan is C-17 Alpha Alkylated (also known as Methylation), which is a process that tends to make oral compounds present a degree of harm to the liver, Primobolan has never shown any measurable hepatotoxic effects to the body. Although oral Primo does not impose any measurable negative effects on the liver, it still presents some small amount of hepatotoxicity and this should still be understood, especially when it comes to extended cycle lengths and/or very high dosages. With that being said, one death of an anemic patient who was prescribed oral Primobolan has been linked to its use. Once again, high doses and/or very long cycle lengths of oral Primobolan may be a concern.
As much as Primobolan is touted by athletes and bodybuilders as being a ‘mild’ anabolic steroid, it still exhibits suppression of endogenous Testosterone production and HPTA function. In fact, studies have confirmed that at even a very low dosage (30 – 45mg daily), test subjects experienced 15 – 65% suppression of natural endogenous Testosterone production. Being that those dosages as far lower than what is required for performance enhancement purposes, it is still heavily recommended to perform a proper PCT (Post Cycle Therapy) following the discontinuation of Primobolan.
