Methenolone regardless of the ester is a very mild anabolic steroid. The androgenic activity of this compound is considerably low, as are its anabolic properties. One should not expect to achieve great gains in muscle mass with this drug. Instead, Primobolan® is utilized when the athlete has a specific need for a mild anabolic agent, most notably in cutting phases of training. It is also a drug of choice when side effects are a concern. A welcome factor is that Primobolan® is not c17 alpha alkylated as most oral steroid are. Due to the absence of such an alteration, this compound is one of the few commercially produced oral steroids that is not notably stressful to the liver. While liver enzymes values have been affected by this drug in some rare instances, actual damage due to use of this substance is not a documented problem. Unfortunately the 1 alkylation and 17-beta esterification of Primobolan® do not protect the compound very well during first pass however, so much of your initial dose will not make circulation. This is obviously why we need such high daily dose with the oral version of Primobolan®.
Primobolan, or Primo, is one of the few anabolic steroids that are available in both oral and injectable forms. While Primobolan is no longer the hugely popular anabolic steroid it once was, it still has a big following amongst bodybuilding enthusiasts across the globe, including famous bodybuilders such as Arnold Schwarzenegger (who was known to use it as one of his main steroids early in his bodybuilding career).
Now, having said all of the above, it has to be said that Primobolan does have its side effects including light acne, deepening voice and increased hair growth (these effects resulting form the androgenic residual effect). However, it displays low liver toxicity and usually has little effect on blood pressure and cholesterol, which makes it one of the safest injectable anabolic steroids. It is also worth pointing out that the bodies own testosterone production is only reduced when high dosages are taken for prolonged periods.
Due to its mild nature, Primobolan is often used in conjunction with other steroids for a stronger effect. In such cases, a slightly lower dose is often used (50 – 100mg per day). During a dieting or cutting phase, thought to be its primary application, a non-aromatizing androgen like trenbolone is often added. Such combinations would enhance the physique without water retention, and help bring out a a harder and more defined look of muscularity. Non-aromatizing androgen/anabolic stacks like this ware very popular among competing bodybuilders, and prove quite reliable for rapidly improving the contest form. This compound is also occasionally used with more potent androgens during bulking phases of training. The addition of testosterone, Dianabol or Anadrol is common, although the gains are ofter accompanied by some level of smoothness due to the added estrogenic component, as well as hepatotoxicity in the case of the latter 2 agents.
Although classified as an anabolic steroid, androgenic side effects are still common with this substance. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Methenolone is still a very mild steroid, however, and strong androgenic side effects are typically related to higher doses. Women often find this preparation an acceptable choice, observing it to be a very comfortable and effective anabolic. Methenolone is not considered a hepatotoxic steroid; liver toxicity is unlikely.
