We are proud to offer TLB-150 (RAD-150) as a solution in a 30ml bottle with a concentration of 20mg/ml.

RAD-150, also known as TLB-150, is a selective androgen receptor modulator (SARM) that has gained attention for its potential benefits in muscle growth and performance enhancement. While research on RAD-150 is limited, this article aims to explore the available information on its mechanism of action and provide insights from in vitro and in vivo studies. Additionally, we will compare RAD-140 and RAD-150 to highlight their similarities and differences.

Mechanism of Action of RAD-150

RAD-150 functions by selectively binding to androgen receptors in the body, specifically targeting skeletal muscle tissue. By activating these receptors, RAD-150 enhances the androgenic signaling pathway, leading to anabolic effects on muscle tissue. Here are the key mechanisms through which RAD-150 operates:

a. Androgen Receptor Activation:

RAD-150 selectively binds to androgen receptors in skeletal muscle cells, triggering a cascade of intracellular events. This activation enhances protein synthesis, promotes muscle growth, and increases muscle strength and endurance.

b. Increased Nitrogen Retention

RAD-150 has the ability to enhance nitrogen retention within muscle cells. Nitrogen is an essential component of protein synthesis, and increased nitrogen retention supports muscle tissue growth and repair.

c. Enhanced Muscle Recovery

RAD-150 may aid in muscle recovery by reducing muscle damage and inflammation. This could potentially lead to faster recovery times between workouts and improved overall training capacity.

In Vitro Studies of RAD-150

In vitro studies, utilizing cell cultures and isolated muscle cells, have provided insights into the cellular mechanisms of RAD-150. However, it is important to note that there is limited research specifically focused on RAD-150. Therefore, the available information is scarce, and more research is needed to fully understand its effects. Nevertheless, in vitro studies have shown promising results, including:

a. Muscle Protein Synthesis

RAD-150 has been shown to stimulate muscle protein synthesis in vitro. By activating the androgen receptors in muscle cells, RAD-150 promotes the synthesis of new proteins, leading to increased muscle growth and strength.

b. Cell Signaling Pathways

RAD-150 has the potential to activate various cell signaling pathways involved in muscle growth, including the mammalian target of rapamycin (mTOR) pathway. Activation of mTOR signaling is associated with increased protein synthesis and muscle hypertrophy.

In Vivo Studies of RAD-150

There is limited information available regarding in vivo studies specifically focused on RAD-150. The majority of research in this area has been conducted on other SARMs, including RAD-140. As such, it is challenging to provide detailed insights into the specific in vivo effects of RAD-150.

RAD-140 vs. RAD-150: A Comparison

RAD-140 and RAD-150 are both SARMs that target androgen receptors and have gained attention in the field of muscle growth and performance enhancement. Here are some key differences between RAD-140 and RAD-150:

a. Chemical Structure

RAD-140 and RAD-150 have different chemical structures. RAD-140, also known as Testolone, is a nonsteroidal SARM that belongs to the class of arylpropionamide derivatives. RAD-150, on the other hand, has a different chemical structure, and specific information regarding its chemical makeup may be limited.

b. Androgenic and Anabolic Activity

RAD-140 is known for its high anabolic activity and relatively low androgenic activity. It exhibits strong tissue selectivity and is primarily designed to stimulate muscle growth and enhance performance while minimizing androgenic side effects.However, due to limited information available on RAD-150, it is challenging to make direct comparisons between RAD-140 and RAD-150 in terms of their androgenic and anabolic activity profiles.

c. Research and Studies

RAD-140 has been extensively studied in both in vitro and in vivo settings. Numerous studies have investigated its effects on muscle growth, strength enhancement, and potential therapeutic applications. In contrast, there is a scarcity of research specifically focused on RAD-150, and further studies are needed to fully understand its effects and potential benefits.

d. Availability and Legality

RAD-140 is more readily available as a research chemical. RAD-150 may be less well-known and less readily available due to its limited research and potentially different legal status in different jurisdictions. It is important to note that the legal status of SARMs may vary by country, and it is essential to comply with local laws and regulations.


RAD-150, also known as TLB-150, is a selective androgen receptor modulator that shows promise in muscle growth and performance enhancement. However, due to limited research on RAD-150, particularly in comparison to RAD-140, detailed information regarding its mechanisms of action and specific effects is limited. Further research is needed to fully understand the potential benefits and risks associated with RAD-150. In the realm of SARMs, RAD-140 has been more extensively studied and is known for its anabolic effects on muscle tissue. As with any performance-enhancing substance, it is crucial to exercise caution, adhere to regulations, and prioritize health and safety when considering the use of SARMs or any other compounds for muscle growth or performance enhancement purposes.
