Methenolone enanthate is an anabolic steroid that has small androgenic action. It has potent action on increase of muscle mass. It is a medicine that do not intensify substantially the muscle mass, that is the reason it may be used for a long period of time. The muscle growth provoked by methenolone enanthate maintains even after stopping usage. It is not recommended for use in females because the acetate does not aromatize into estrogen and does not preserve the water in organism. It has properties of fat burning, however it should rather be used for the indicated above purposes. Methonolone enanthate is a drug that may be obtained without prescription. However, patients are indicated to consult a doctor first and get the appropriate dosage for desired purpose.

Lets flesh out some of the various general effects of Primobolan, before we get into the differences between the oral and injectable versions… One study performed on sheep involved administering 100mgs of Methenolone, and electronically stimulating their lats (electronic stimulation was used because they kept falling off the chin-up bars). Anyway, when compared with the lat muscles of sheep who didnt receive Methenolone, the receiving group gained significantly more muscle mass as well as strength. Its also has a relatively high affinity for binding to the AR, actually binding better than testosterone. This ability to strongly bind to the AR may be why Primobolan is such a good "fat burner." Strong AR binding has been positively correlated with lypolysis (fat-burning).

In addition, as this steroid can actually aid in reducing breast tumors, no ancillary products need be considered for use with Primobolan, and in fact, it may actually be a useful ancillary agent in its own right, similar to Masteron. Also, just like Masteron, Primobolan has no propensity to aromatize (convert to estrogen). Since it doesnt aromatize, alot of the side effects commonly associated with estrogen will not be of concern. This means water retention, acne, and gyno will be non-existent more or less. this lack of water retention combined with the slow and steady gains provided by Primo may help to explain why it has earned a reputation for creating quality muscle gains. This also helps to explain why it is so expensive. Although estrogenic sides are not a concern, hair loss still, remains a very real concern with Primobolan, as with many DHT-Derived steroids. Many primobolan fans always include Finasteride and Ketoconazole (shampoo) in cycles containing Primobolan.

Although nobody would ever suggest to use Primobolan as a bulking agent, its been studied as an agent to halt wasting and possibly reverse many of the adverse effects of anemia. It is a shocking failure in both areas, according to some of the case studies Ive read,and this should come to no surprise to anyone. Anadrol reigns supreme in this area, and nobody in the athletic community would ever compare those two drugs. However, Michael Mooney and many other respected doctors who work with AIDS patients have found sufficient evidence to claim that Primobolan is an immune enhancer and as such is very useful for AIDS patients (not that the FDA cares…Primobolan is still not approved for sale in the United States). AIDS patients arent really in need of Bulking Drugs, so an immune enhancer like Primo which will add small, quality gains in muscle is perfect for them. And since we arent even going to vaguely consider the use of Primobolan as a bulking agent, clearly this leaves us with considering it primarily for use in gaining and maintaining lean tissue. Its a great choice for this purpose, and many competitors have used it very successfully to retain muscle while on a calorie reduced diet. The reason Primo is so useful for this purpose is that one of its primary functions is to help your body retain nitrogen at a greatly enhanced rate. The greater your nitrogen retention is, the more muscle you will build. In the case of using primo as a pre-contest drug, this nitrogen retention will help you retain muscle and ensure that your dieting preferentially favors fat loss over muscle loss.

Primobolan Side Effects:

Primobolan is widely held in high regard as one of the few anabolic steroids that is considered very 'mild' in the sense that it presents absolutely zero risk of any Estrogenic side effects at any dose as well as its very weak androgenic strength rating, which allows it to exhibit far less severity in terms of the potential of androgenic side effects than most other anabolic steroids. This is the reason as to why Primobolan is often pitted against and compared to its close brother, Anavar. Both are anabolic steroids that have been utilized medically in the treatment of women and children with very little risk of ill effects and both are considered very 'mild' in regards to potential side effects. This is, however, where the similarities between the two end, as Primobolan is an anabolic steroid that possesses not only a weak affinity for various side effects, but also a weak anabolic strength when compared to the majority of other anabolic steroids in existence (and in comparison to Anavar).

Do I inject primobolan or take it orally?

Currently, there are two forms of primo on the market. The first, and most popular, version is enanthate, which is an injectable form. It comes in an oil based solution in ampules or multi-use vials. The second version is acetate, which is an oral 1-methylated version. Both esters have benefits and drawbacks.


300-800 mg per week. Women also find this steroid favorable due to its mild nature and generally respond well to dosages of 100-200 mg a week.
