Undebolic — 250mg Testosterone Undecanoate

Undebolic contains 250mg of Testosterone Undecanoate.


Undebolic (Testosterone Undecanoate) is an injectable steroid that exhibits strong anabolic and moderately androgenic properties.

Estrogenic Side Effects

Undebolic (Testosterone Undecanoate) 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.

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.

Hepatotoxicity Side Effects

Undebolic (Testosterone Undecanoate) 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.

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 when taken in doses sufficient to promote muscle gain are expected to suppress 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.

Administration for Men

For the treatment of low androgen levels, it is most commonly used at an initial dosage of 120 – 160 mg daily for 2-3 weeks. Based on the level of effect, a daily maintenance dosage of 40-120 mg is usually continued at this point.

For bodybuilding purposes, it is most commonly used at a dosage of 240 – 480 mg per day.

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

Undebolic (Testosterone Undecanoate) should always be taken with meals, preferably containing a moderate fat content (20 grams) to maximize lymphatic absorption. The total daily dosage should be divided into a minimum of two applications, taken in the morning and evening.

Undebolic (Testosterone Undecanoate) is a very versatile drug, and can be combined with a number of other agents depending on the desired result.

Administration for Women

Undebolic (Testosterone Undecanoate) is rarely used with women in clinical medicine.

Undebolic (Testosterone Undecanoate) is not recommended for women for performance enhancing purposes due to its strong androgenic nature and tendency to produce virilizing side effects.
