S2 Classification

Meaning

S2 Classification refers to a specific and critical category within the World Anti-Doping Agency’s (WADA) Prohibited List, which designates peptide hormones, various growth factors, and their related substances as strictly prohibited in sport at all times, both in and out of competition. This classification is of paramount importance in the athletic and longevity space, as it includes powerful compounds that profoundly affect the endocrine system, such as Erythropoietin (EPO), Human Growth Hormone (hGH), and various insulin-like growth factors. The detection of these substances is considered a severe anti-doping rule violation.
