Definitions (stance-aware)

• Performance-enhancing drugs (PEDs): pharmacological or biological agents (EPO, anabolic steroids, HGH, blood-doping) that exogenously alter physiology to enhance performance beyond training/nutrition/rest, falling within or analogous to the WADA Prohibited List.
• Permitted: allowed for in-competition (and/or out-of-competition) use without sanction, whether fully legalised or "medically supervised/threshold-based."
• Professional sports: organised, rule-governed competitions for pay, ranking, and titles under bodies recognising WADA-style anti-doping codes.
• Fairness (sporting): protecting the fair value of victory — competition decided by skill, training, and tactics rather than pharmacology or access to biomedical capital.
