Boldenone Undecylenate

Boldenone Undecylenate

What is Boldenone Undecylenate?

Boldenone undecylenate is a derivative of testosterone used for increasing muscle mass and strength and promoting athletic performance. It is a very popular anabolic steroid due to its moderately androgenic properties and its pronounced effect on lean bodyweight, appetite and general disposition. The undecylenate ester attached to boldenone steroid has the property of extending the activity of the drug, so that it has to be administered less frequently than other steroids. Also, boldenone undecylenate is one of the few steroids that have the ability to increase red blood cell production. Due to its strong anabolic properties and moderate androgenic, boldenone undecylenate has become a popular steroid in recent years. All users are recommended to read carefully about specifics of this steroid, such as: methods of administration, side effects, interaction with other drugs and others.

Brand names

Boldenone undecylenate is an anabolic steroid sold under the Equipoise brand name.

General Warnings with boldenone undecylenate

Do not use this drug if you have an increased sensitivity to the drug. Usually the symptoms of hypersensitivity to a drug are the following: swelling of the face, lips and tongue, anaphylactic reactions and others. Also, if you have a medical history of cardio-vascular diseases, cancer and renal or liver disease, avoid this drug.

Specific features of boldenone undecylenate

-Boldenone undecylenate is an efficient steroid in terms that it increases muscle mass and contributes to creation of what athletes call it "quality muscle mass".

-It is a versatile drug. It may be stacked with other steroids for obtaining good results in a relatively short period of time.

-It may convert into estrogen through the aromatization process, but the estrogen related side effects are so pronounced as in case of other steroids.

-It is an easy-to-administer due to the fact that it comes in form of injectable solution.

Indications of use and dosage

In order to benefit most from the use of boldenone undecylenate, it is recommended to follow properly the indications of use and dosage. Boldenone undecylenate is a steroid that comes in form of injectable solution. The undecylenate ester attached to the boldenone steroid makes it a long acting steroid; therefore, it is indicated to inject the drug at least once per week. The usual dose of boldenone undecylenate is from 200mg to 400 mg per week (50mg version). From this reason, the administration of boldenone undecylenate might be quite uncomfortable and painful. In order to administer the drug much easily and not experience much discomfort, the drug might be injected in several doses. It is also recommended to change the injection site so that the user does not experience pain, irritation and infection. In order to eliminate such concerns with 50mg version, one may use 100mg and 200mg versions that will give much more flexibility and comfort in administering doses.

One may see the results with boldenone undecylenate in a period of 16 weeks. Boldenone undecylenate is not a rapid mass builder, but it provides steady gain of strength and what athletes call it "quality muscle mass". From this reason, if one wants to obtain results in a short period of time, boldenone undecylenate might not be the right choice. Boldenone undecylenate is effective in terms of creating defined and solid muscle mass. This is one of its most important features and what distinguishes it from other steroids. Moreover, boldenone undecylenate is a very versatile steroid, which means that it can be combined with a number of steroids depending on the desired result.

It is important to follow the doses as indicated. Increased doses increase the incidence of developing estrogen related side effects.

Important tips for administration of boldenone undecylenate

Before administering the injection, it is important to look up and take into consideration the following steps:

-Inspect the vials very well for detecting any particles that might have formed if stored at low temperatures.

-If any particles are detected, keep the vial for a couple minutes in your hand in order to warm it up and have the particles dissolved.

-Shake well the vial in order to ensure an even distribution of steroid.

-Inject the solution.

Possible side effects with boldenone undecylenate

Like many other anabolic steroids, boldenone undecylenate may cause side effects. Generally, these are mild and short in action. Boldenone undecylenate has the ability to convert into estrogen through the aromatization process. Therefore, estrogen related side effects are possible with boldenone undecylenate. Even so, such side effects as water retention, gynecomastia and others are not as pronounced as in case of such steroids as nandrolone decanoate, as it has an estimation of 20% conversion to estrogen. In order to decrease the incidence of estrogen related side effects it is recommended to take antiaromatase agents. Another important thing to mention is that some estrogen-related side effects as gynecomastia depend on susceptibility of the user to such effects. Gynecomastia might theoretically become a concern, but if taking all measures of precaution and respect the dosage, it may not be a problem.

Other possible side effects with boldenone undecylenate are the following:

·Oily skin;

·Acne, in some users it may become a real problem as it may occur on the chest, back and shoulder areas. Users mostly prone to acne should use anti-bacterial and anti-acne soap daily in order to avoid such side effects.

·Increased aggression;

·Increased appetite;


·Hair loss.

Women may experience virilization symptoms when using boldenone undecylenate at high dosages. Therefore, it is important to use low doses and take all measures of precaution to avoid any side effects.

Also, it is important to mention that boldenone undecylenate may cause unusual changes in mood, decrease in sexual desire and suppression of testosterone. The suppression of testosterone levels is not a serious concern. After discontinuing with boldenone undecylenate one may take additional testosterone until the levels go up to the normal ones.


It is recommended to store boldenone undecylenate at the room temperature below 25 degrees Celsius. The ampules should be kept out of the reach of children and away from the direct sunlight exposure. Safely discard the drug if no longer needed or expired. Ask a pharmacist for more details.
