Boldabolic (Boldenone Undecylenate) is an injectable steroid that exhibits strong anabolic and moderately androgenic properties.

Estrogenic Side Effects

Boldabolic (Boldenone Undecylenate) is aromatized in the body to estradiol (estrogen). Elevated estrogen levels can cause side effects such as increased water retention, body fat gain, and gynecomastia.

Boldabolic (Boldenone Undecylenate) is considered a mildly estrogenic steroid with estrogenic side effects usually not pronounced unless this drug is taken in doses above 200 – 400 mg per week. An anti-estrogen may be necessary to prevent estrogenic side effects. One may alternately use an aromatase inhibitor which more efficiently controls estrogen by preventing its synthesis.

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.

Hepatotoxic Side Effects

Boldabolic (Boldenone Undecylenate) does not have hepatotoxic effects and therefore, liver toxicity is unlikely.

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.

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.

Boldabolic (Boldenone Undecylenate) is likely to have a less dramatic impact on cardiovascular risk factors than synthetic oral anabolic steroids.

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 200 – 400 mg per week. The dosage schedule can be further divided to reduce the volume of each injection if necessary, perhaps administering the drug two to three times per week. One should also take caution to rotate injection sites regularly, so as to avoid irritation or infection.

The positive effects of this drug become most apparent when it is used for longer cycles, usually lasting 8 weeks or more in duration.

Boldabolic (Boldenone Undecylenate) is a very versatile drug, and can be combined with a number of other agents depending on the desired result.

Administration for Women

When used for physique- or performance-enhancing purposes, women take much lower doses of Boldabolic (Boldenone Undecylenate) than men, typically 50 – 75 mg per week.

Women should take caution with the slow-acting characteristics of this preparation, which make blood levels difficult to control and slow to decline should virilization symptoms become present.
