In the realm of sports and bodybuilding, achieving optimal performance and a well-sculpted physique is a common aspiration. One compound that has garnered attention in this pursuit is injectable Equipoise, also known as Boldenone Undecylenate 400. Manufactured by SP-Laboratories, this compound has gained popularity for its potential benefits in enhancing physical performance and muscle development. In this article, we’ll delve into its general description, indications, contraindications, uses in bodybuilding and sport, medical actions, combination with other drugs, recommended dosage, and potential side effects.

General Description:

Injectable Equipoise, known scientifically as Boldenone Undecylenate 400, is a synthetic anabolic steroid derived from testosterone. SP-Laboratories manufactures this compound, which is designed to mimic the effects of the naturally occurring hormone testosterone in the body. It is typically administered through intramuscular injection and is available in various dosages.


Equipoise is primarily indicated for medical conditions that involve muscle wasting, anemia, and low red blood cell count. Its ability to stimulate erythropoiesis, the production of red blood cells, makes it useful in treating these conditions. Additionally, Equipoise has been explored for its potential benefits in improving bone density and aiding in the recovery process post-injury.


Like any pharmaceutical compound, Equipoise has its contraindications. It is not recommended for individuals with a history of hypersensitivity to Boldenone Undecylenate or any of its components. Pregnant and breastfeeding women should avoid using Equipoise due to potential risks to fetal development. Individuals with pre-existing medical conditions, such as liver or kidney disorders, should consult a medical professional before using this compound.

Uses in Bodybuilding and Sport:

Equipoise has gained popularity in the world of bodybuilding and sports due to its potential to enhance muscle growth, strength, and endurance. Athletes may use it during their bulking cycles to promote lean muscle mass development. Equipoise’s slow and steady release mechanism allows for sustained effects over time, making it an attractive choice for those seeking gradual improvements.

Medical Action:

Equipoise exerts its effects by binding to androgen receptors in muscle cells, leading to an increase in protein synthesis. This process contributes to muscle growth and repair. Moreover, its ability to stimulate erythropoiesis results in higher red blood cell counts, promoting enhanced oxygen delivery to muscles, which can improve endurance and performance.

Combination with Other Drugs:

Equipoise is often used in combination with other anabolic steroids to maximize its effects. For instance, it may be stacked with compounds like Testosterone or Trenbolone to enhance muscle-building potential. However, combining steroids requires careful consideration of dosage and potential interactions to avoid adverse effects.


The recommended dosage of Equipoise (Boldenone Undecylenate 400) can vary based on individual goals and experience levels. For beginners, a typical dosage ranges from 300 to 600 milligrams per week. More advanced users may opt for higher dosages, but it’s essential to remember that increasing the dosage also increases the risk of potential side effects.

Side Effects:

While Equipoise is known for its relatively mild nature compared to some other anabolic steroids, it is not without potential side effects. Some users may experience androgenic effects, such as acne, hair loss, and an increase in facial and body hair. It can also have a negative impact on cholesterol levels and suppress natural testosterone production. Additionally, improper use or excessive dosages may lead to more severe side effects, including cardiovascular issues and liver strain.


Injectable Equipoise (Boldenone Undecylenate 400) by SP-Laboratories presents an intriguing option for individuals in the realms of bodybuilding and sports seeking to enhance their performance and physique. While it offers potential benefits such as muscle growth, increased strength, and improved endurance, it’s crucial to approach its usage with caution and responsibility. Consulting a medical professional before starting any steroid regimen is advisable, as well as adhering to recommended dosages and understanding potential risks and side effects. In the quest for excellence, informed decisions and a balanced approach are key to achieving the desired outcomes safely and effectively.
