Primobolic — 25mg Methenolone Acetate

Primobolic contains 25mg of Methenolone Acetate.


Primobolic (Methenolone Acetate) is an oral anabolic steroid.

Primobolic (Methenolone Acetate) is highly favored by athletes during cutting phases of training, when lean tissue growth and solid muscularity, not raw bulk, are the key objectives.

Estrogenic Side Effects

Primobolic (Methenolone Acetate) is not aromatized by the body, and is not measurably estrogenic. An anti-estrogen is not necessary when using this steroid, as gynecomastia should not be a concern even among sensitive individuals.

Androgenic Side Effects

Although classified as an anabolic steroid, androgenic side effects are still common with this substance, especially with higher doses. This may include bouts of oily skin, acne, and body/facial hair growth.

Anabolic/androgenic steroids may also aggravate male pattern hair loss.

Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement.

Hepatotoxicity Side Effects

Primobolic (Methenolone Acetate) does not have hepatotoxic effects and therefore, liver toxicity is unlikely. Although unlikely, hepatotoxicity cannot be completely excluded, especially with high doses.

Cardiovascular Side Effects

Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis.

The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism.

Primobolic (Methenolone Acetate) should have a stronger negative effect on the hepatic management of cholesterol than testosterone or nandrolone due to its non-aromatizable nature, but a much weaker impact than c-17 alpha alkylated steroids. Due to the route of delivery, oral methenolone will have a slightly stronger negative effect on lipids compared to methenolone enanthate injections.

Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.

To help reduce cardiovascular strain, it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active steroid administration. Supplementing with fish oils and a natural cholesterol/antioxidant formula is also recommended.

Testosterone Suppression

All anabolic/androgenic steroids are expected to suppress endogenous testosterone production. Testosterone is the primary male androgen, and offers strong negative feedback on endogenous testosterone production.

Testosterone-based drugs will, likewise, have a strong effect on the hypothalamic regulation of natural steroid hormones. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession.

Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.

Administration for Men

It is most commonly used at a dosage of 75-150mg per day, taken in two to three doses during the day.

The positive effects of this drug become most apparent when it is used for longer cycles, usually lasting 6-8 weeks.

Primobolic (Methenolone Acetate) is a very versatile drug, and can be combined with a number of other agents depending on the desired result, in which case the daily dosage should be lowered to 50-100mg.

For maximum utilization Primobolic (Methenolone Acetate) should be taken on an empty stomach.

Administration for Women

When used for physique- or performance-enhancing purposes, women take much lower doses of Primobolic (Methenolone Acetate) than men, typically 50 – 75 mg daily, with no signs of virilization symptoms.

For maximum utilization Primobolic (Methenolone Acetate) should be taken on an empty stomach.
