Trenbolone 100 Enanthate, manufactured by SP-Laboratories, is a potent injectable drug that has gained popularity in both the medical field and the realm of bodybuilding and sports. Known for its remarkable effects on muscle growth and performance enhancement, this drug has sparked interest among athletes, bodybuilders, and medical professionals alike. In this article, we’ll delve into the general description, indications, contraindications, uses in bodybuilding and sports, medical actions, combination with other drugs, recommended dosage, and potential side effects of Trenbolone 100 Enanthate.

General Description:

Trenbolone 100 Enanthate is a derivative of the anabolic steroid nandrolone, but with enhanced anabolic and androgenic properties. It is classified as a synthetic anabolic steroid, designed to mimic the effects of testosterone within the body. The Enanthate ester attached to Trenbolone slows down its release into the bloodstream, providing a sustained effect over time.


In the medical field, Trenbolone 100 Enanthate has limited indications and is not approved for human use in most countries. It is primarily utilized in veterinary medicine to promote muscle growth in livestock. Due to its potency and potential for adverse effects, the use of Trenbolone in humans is carefully regulated and monitored.


Trenbolone 100 Enanthate is contraindicated in individuals with a history of hypersensitivity to anabolic steroids, as well as those with pre-existing medical conditions such as prostate cancer, breast cancer, and cardiovascular issues. Pregnant and breastfeeding individuals should avoid the use of this drug due to potential risks to fetal development.

Uses in Bodybuilding and Sport:

Trenbolone 100 Enanthate has gained significant attention in the bodybuilding and sports communities due to its ability to promote lean muscle mass, enhance strength, and improve overall athletic performance. Bodybuilders often incorporate Trenbolone into their cutting and bulking cycles to achieve a well-defined and muscular physique. It is believed to help in the reduction of body fat while preserving lean muscle tissue.

Medical Action:

Trenbolone 100 Enanthate exerts its effects by binding to androgen receptors in the body. This interaction enhances protein synthesis, leading to increased muscle growth and improved nitrogen retention. Additionally, it boosts red blood cell production, promoting enhanced oxygen delivery to muscles, thereby improving endurance and performance.

Combination with Other Drugs:

In the realm of bodybuilding, Trenbolone 100 Enanthate is often combined with other anabolic steroids or performance-enhancing drugs to amplify its effects. However, such combinations should be approached with caution due to the potential for increased risks and side effects. Commonly paired compounds include testosterone and other compounds for muscle building and fat loss.


The recommended dosage of Trenbolone 100 Enanthate can vary widely based on individual goals, experience level, and tolerance to the compound. In the bodybuilding community, dosages typically range from 200 to 600 milligrams per week. However, due to its potency, beginners are advised to start at the lower end of the spectrum and gradually increase as needed, under the supervision of a medical professional.

Side Effects:

Like all anabolic steroids, Trenbolone 100 Enanthate is associated with potential side effects, which can range from mild to severe. Common side effects include increased aggression, acne, oily skin, hair loss (in individuals genetically predisposed), and disruption of natural hormone production. More serious side effects can include cardiovascular strain, liver stress, and negative impacts on cholesterol levels.


Trenbolone 100 Enanthate, manufactured by SP-Laboratories, is a powerful injectable drug with distinct anabolic and androgenic properties. While its use is limited in the medical field, it has gained prominence in bodybuilding and sports due to its ability to promote muscle growth, enhance strength, and improve athletic performance. As with any performance-enhancing substance, responsible use, careful monitoring, and professional guidance are essential to minimize risks and optimize benefits. Individuals considering the use of Trenbolone 100 Enanthate should weigh the potential gains against the potential risks and always prioritize their health and well-being.
