Magnum Primo 100

What is Magnum Primo 100 by Magnum Pharmaceuticals?

Magnum Primo 100 is an oil-based injection of methenolone enanthate produced by Magnum Pharmaceuticals. The "100" refers to its strength of 100mg/ml, the same concentration as the classic Primobolan Depot ampoules that made the compound famous. A box contains 5 ampoules.

Methenolone enanthate has been in use since the 1960s. Chemically it is a modified form of dihydrotestosterone, bound to the enanthate ester so that a single injection releases the hormone over many days. As a DHT derivative it cannot be converted into estrogen, and it is considered one of the gentler anabolic steroids in terms of androgenic load.

Effects of Magnum Primo 100

Bodybuilders who pick methenolone enanthate are usually after quality rather than quantity. In a calorie surplus it supports slow, lean muscle gain with little fat or water; in a deficit it helps preserve the muscle that hard dieting tends to strip away. Many users notice better recovery and a gradual climb in strength, and the physique looks fuller and harder as body fat falls.

Another reason for its popularity is the absence of estrogen-related problems such as water retention and breast tissue growth, so on its own it gives no reason to use an aromatase inhibitor. The trade-off is a modest anabolic effect, which means expectations should stay realistic.

Common dosage ranges

For men, commonly reported weekly doses of methenolone enanthate range from 400 to 600 mg, sometimes more among experienced users, divided into two injections a week. Courses tend to last ten to fourteen weeks, because the long ester needs time to reach a steady level. At these amounts a full course usually takes more than one box of five ampoules. Women are reported to use much smaller amounts, and only while watching closely for early signs of virilization.

The figures above are only the typical ranges found in the literature and in practice. The individual dose and duration of Magnum Primo 100 must be agreed with a qualified medical professional.

Potential side effects

Even a mild steroid affects the whole hormonal system. Reported side effects of methenolone enanthate include:

• suppression of the body's own testosterone and sperm production;
• thinning hair in men with a family history of baldness;
• acne on the face, back and shoulders;
• a worse cholesterol profile, with HDL going down;
• pain, warmth or swelling at the injection site;
• in women, voice changes, excess body hair and disrupted cycles.

People under 18, women who are pregnant or may become pregnant, and anyone with heart disease, hypertension or a hormone-dependent cancer should avoid it.
