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.
