M2. Chemical and Physical Manipulation
Tampering or attempting to tamper with a collected sample in order to affect its integrity or validity is prohibited. This includes providing synthetic urine or urine that is not the athlete’s own, or any modification of the urine sample, such as addition of proteases.
Intravenous infusions and intravenous injections of any substance containing more than 50 milliliters given in less than a six-hour period are prohibited, unless it is administered legitimately during the course of hospital admissions, surgical procedures, or clinical investigations.
Advisory:
- Even if the substance delivered by intravenous infusion is permitted (e.g., iron), the method is prohibited if given outside of a hospital/surgery/ admission/surgery/clinical investigation because it is diluted in more than 50 milliliters of fluid. Intravenous injections of less than 50mL are only prohibited if the substance is included on the prohibited list.
- In an emergency, an athlete should always receive appropriate medical care. If the emergency medical providers need to insert an intravenous line or provide medications as a life-saving procedure, request copies of all the clinical documentation for the diagnosis, decision to start the IV, and the amount of fluid administered. Once the emergency is over, the athlete should contact USADA to determine if a TUE is required.
- The use of IV infusions in place of or in addition to oral fluid intake, such as to relieve severe dehydration caused by gastrointestinal distress during travel, without hospitalization, is prohibited. Also, WADA clarified “the use of IV fluid replacement following exercise to correct mild re-hydration is not clinically indicated nor substantiated by the medical literature.”
