Anavar increases muscle mass by inducing protein synthesis in the body, up-regulating the androgen receptor in skeletal muscle, and increasing IGF-1 (insulin-like growth factor). Thus, Anavar has a much higher potential to promote anabolic effects on the human body, such as increasing muscle size, strength, and nitrogen retention, reducing fat deposition, and inducing protein synthesis compared to testosterone.
As a result, Anavar can reduce unwanted androgenic effects and enable more anabolic properties.
