Magnum Primo 100


Manufacturer: Magnum Pharmaceuticals
Substance: Methenolone Enanthate (Primobolan Depot)
Package: 5 ampoules (100mg/ml)

The injectable version of the steroid Methenolone is known as Primobolan Depot (Magnum Primo 100) and it is produced by Magnum Pharmaceuticals. An Enanthate ester is added to this steroid to ensure that the drug is released slowly into the bloodstream once it has been injected. As a result, the injectable preparation created is Methenolone Enanthate. Its half-life is 10-14 days and blood levels remain elevated for another two weeks. Its anabolic effects can be considered to be moderate compared to other anabolic steroids but is similar to that of Deca Durabolin. Its androgenic properties are also quite low.

Effectiveness of Primobolan

For the most part users should not expect to make major gains in muscle mass from this drug but rather lean gains in muscular body weight. In some animal studies it has been demonstrated that Methenolone has the potential to increase muscular size and strength. However, the anecdotal evidence from users suggest that any mass gains using the compound will not be overly significant. It has been noted as quite an effective “cutting” drug because of its ability to bind to the androgen receptors in the body. Of course the ability to bind to androgen receptors has been shown to promote fat burning in individuals. This effect would obviously be highly desirable during “cutting” phases or to simply limit the amount of body fat one puts on during a bulking phase.

Side effects

Methenolone does not convert to estrogen and therefore estrogenic side effects should not be a concern with this compound. By emphasizing the anabolic nature and reducing the harsher androgenic qualities, Primobolan was designed to have as few side effects as possible, which is most definitely the case.

Suppression of the HPTA is minimal and increased blood pressure, liver damage, the risk of gyno, or any ill feeling at all is virtually non-existent with Primobolan. This steroid used in low and moderate levels, does not suppress the production of testosterone in the body. However, at higher levels, testosterone suppression can occur. The occurrence of other side effects also increase as the dosage of Primobolan is increased. Side effects include acne, oily skin, increased face and body hair growth, male pattern baldness, as well as some mild virilization side effects for women.


Beginners are recommended a weekly dose of 400mg, which can be quite low for extreme bulking effect. Most suggest that a minimum weekly dose of 500mg is needed to see appreciable bulking and muscle gain. Experienced athletes and bodybuilders looking for great results often use 700 to 1000mg of Primobolan a week. The recommended dose for female users is 50 to 100mg per week. An average Primobolan cycle is between 6 and 12 weeks, often the cycle can be extended up to 20 weeks.

Primobolan is often used with bulking drugs such as Dianabol, Anadrol, Stanozolol and during a cutting phase, with non-aromatizing androgens like Halotestin or Trenbolone Enanthate.
