Primobolan (methenolone acetate), all things being equal, is an excellent oral steroid drug. Unlike most other oral steroids, Primobolan is not 17-alkylated and does not have liver toxicity problems.

Among athletes primobolan is generally known as a mild steroid which provides slow steady gains in quality muscle mass while not being harsh on one’s system. It is often used in cutting cycles when the athlete is in a calorie restricted diet and trying to preserve muscle mass while shedding bodyfat. Primobolan is notorious for being very effective in this particular case. It is also popular for athletes looking to add a little muscle and strength in speed related or weight restricted sports. Primobolan is not aromatized by the body and therefore doesn’t convert to estrogen. Therefore, estrogen related side effects shouldn’t be a concern when taking this agent and users need not worry about taking any anti-estrogens when running it by itself.

Primobolan Acetate is very strong, the synthesis of the metabolism and male characteristics is very low, making it the best choice for the game. The drug for women is very good.

This drug is very similar in action the injectable version of the drug which is known as primobolan depot, except that with this drug it has been designed for oral administration instead of injection. The acetate ester makes the drug much more faster acting than the depot version. Methenolone acetate is a non C17 alpha alkylated oral steroid, which makes it one of the few commercially available oral agents that presents limited liver toxicity to the user


Users of the oral version of primobolan for performance enhancing purposes would often choose to run it at a dosage of 100-150mg per day. The injectable form of the drug is used in dosages of 300-800 mg per week depending on the users experience and what the personal goals are. Women also find this drug favorable due to its mild nature and generally respond well to dosages of 50mg per day of the oral preparation and 100-200 mg a week of the injectable version.
