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, (5)(6) 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.
