Learn More How It Works

YK-11 is a steroidal Selective Androgen Receptor Modulator (SARM) that belongs to the 19-Nor family (nandrolone). Unlike other SARMs, YK-11 has a unique mechanism of action as it is known for its myostatin inhibiting properties. Myostatin is a protein that suppresses muscle growth, and by inhibiting it, YK-11 allows for greater potential in muscle development.

As a compound with anabolic activity, YK-11 promotes significant increases in muscle mass and strength. However, it’s essential to note that YK-11 has a mild androgenic nature and is often compared to anabolic steroids. It binds directly to androgen receptors in muscle tissue, which can result in the growth of muscle mass and increased endurance.

Typically, a dosage of 5-10 mg per day is recommended for YK-11, with a cycle length ranging from 4-8 weeks. It’s essential to adjust the dosage and cycle length according to individual tolerance and experience. As with other SARMs, a Post Cycle Therapy (PCT) is often necessary to recover natural testosterone production and avoid unwanted side effects after the cycle.

While YK-11 may offer muscle-building benefits, it’s crucial to understand the potential risks associated with its use. It might lead to a decrease in the production of IGF-1 (Insulin-like Growth Factor) and increased conversion to DHT (Dihydrotestosterone). Moreover, as a steroidal SARM, YK-11 may pose additional health concerns when compared to non-steroidal SARMs. Thus, one should research and make an informed decision before considering YK-11 as part of their regimen.

When comparing YK-11 to other SARMs such as RAD-140, it’s important to understand their differences in mechanism of action, benefits, and potential side effects and choose the one that suits one’s goals and risk tolerance.

Understanding RAD-140

RAD-140, also known as Testolone, is a popular Selective Androgen Receptor Modulator (SARM) known for its potent anabolic effects. It primarily focuses on binding to androgen receptors in muscle and bone tissue, promoting muscle growth without the side effects typically associated with traditional steroids.

RAD-140 is particularly known for its benefits in promoting muscle mass, strength, and endurance. By selectively targeting muscle tissue, it offers users a lower-risk alternative to traditional anabolic steroids while still delivering results desired by bodybuilders and athletes.
