The phrase "anabolic steroids" refers to testosterone derivatives that are utilised for their anabolic qualities in either clinical settings or by athletes. For decades, scientists have questioned testosterone and its derivatives' anabolic effects on normal men. The majority of scientists believe that anabolic steroids do not boost muscle size or strength in adults with normal gonadal function, and that positive results are skewed by athletes' high expectations, bad study design, or inadequate data processing. There has been a significant divergence between athletes' belief that these medicines are effective and experts' belief that they aren't. This discrepancy is due, in part, to the radically different dosing regimens utilised by scientists to document the treatment of deficient states and by athletes attempting to improve athletic performance.
