Primobolan Benefits

Primobolan is considered a fairly weak steroid. Its anabolic/androgenic ratings are low and it’s one of the weakest steroids on paper; though, it is stronger than masteron. Since masteron is always related to cutting cycles, on paper primo should gain credibility as a cutting steroid.

Primo has a huge advantage over most steroids, as it’s stronger than testosterone at binding to the androgen receptor. As with most dihydrotestosterone (DHT) related AAS, it’s a good aid for fat loss. In addition, primo doesn’t aromatize, so you won’t need an aromatase inhibitor (AI) or SERM with it. Interesting fact, primobolan was tested by old-school bodybuilders as gynecomastia (gyno) treatment back in the 70s and 80s. As strange as it sounds, it has been medically proven to reduce breast tumors in women (which are mainly estrogen related).

Since primobolan increases nitrogen retention, it’s been touted as anti-catabolic, and somewhat anabolic (which can be disputed). In simple terms, it helps you keep your muscle mass while you’re dieting. That’s one of the biggest reasons it’s used on cutting cycles. Anecdotally, evidence shows that by using primobolan during low-calorie diets (even 20-30% below your BMR), you can keep your current lean muscle while gaining new muscle tissue. While this seems to be against basic understanding of nutrition, we’ll chuck this one to the magic of steroids.

Safest Steroid

Metenolone enanthate (methenolone enanthate) is a dihydrotestosterone (DHT) based anabolic steroid.It is an ester derivative of methenolone sold commonly under the brand names Primobolan (tablet form) or Primobolan Depot (injectable). When it interacts with the aromatase enzyme it does not form any estrogens.It is used by people who are very susceptible to estrogenic side effects, having lower estrogenic properties than nandrolone.

Primobolan Depot is an injectable form of the steroid methenolone,it has long been regarded as one of the safest steroids available. Methenolone enanthate has the same base steroid as methenolone acetate. Primobolan Depot has been modified to allow a slow release of methenolone in the body. Primobolan Depot is a moderately anabolic with an extremely low androgenic profile. The anabolic effects are comparable with Deca Durabolin, although the androgenic side effects are considerable less. Athletes and bodybuilders will take Primobolan Depot to gain lean muscle mass. The gains that you will get on a cycle of Primobolan will be a slow gain in quality muscle. You can expect to keep the gains for a few months after finishing your cycle.

An interesting note that is not seen with many other anabolic steroids is that Primobolan has been used to promote weight gain in underweight premature infants and children. Primobolan Depot proved to this effectively without showing signs of toxicity or undesirable side effects.
