Across the U.S., EPO laws are mostly consistent because they are governed at this level of government.

What is the federal level?

100

This performance-enhancing drug, known for boosting red blood cell production, is not considered reinforcing in humans or animals because it does not directly activate the brain’s reward pathways like addictive substances.

What is Erythropoietin (EPO)?

100

After taking this drug, an athlete might notice this ability to exercise longer without getting tired as quickly

What is endurance? 

100

EPO is extremely potent, a high dosage for an athlete is defined as exceeding this certain amount of Total International Units (IU) per week.

What is 13,750 IU?

100

This drug is used by athletes to help increase endurance by increasing oxygen-carrying capacity in the blood

What is EPO (Erythropoietin)?

200

In the United States, obtaining EPO legally requires this from a licensed healthcare provider.

What is a valid prescription?

200

The main athletic benefit of EPO use is increased physical stamina and...

What is endurance?

200

A person using this drug may feel less of this sensation during workouts due to improved oxygen delivery to the muscles.

What is fatigue?

200

While natural EPO is produced by the kidneys, this "recombinant" synthetic version is so potent it can increase a person's VO2 max (oxygen capacity) by up to 15%.

What is rhEPO (Recombinant Human Erythropoietin)?

200

How does erythropoietin (EPO) typically appear when prepared for medical or performance-enhancing use?

What is a clear and colorless liquid?


300

If prosecutors prove intent to defraud or mislead in distributing EPO, the maximum prison sentence increases to this length.  

What is up to 3 years in prison? (felony) 

300

A dangerous long-term risk of EPO use caused by thickened blood is this event in the brain.

What is a stroke?

300

This short-term physiological effect of EPO use occurs when blood becomes thicker due to increased red blood cell production, which can cause headaches 

What is increased blood viscosity?

300

In performance-enhancing contexts, individuals may utilize "micro-dosing" by administering small, frequent intravenous doses of approximately this many units. To avoid detection by anti-doping tests, many athletes have switched from "bolus" injections to this method, involving small, frequent doses of roughly 500–1,000 units.

What is micro-dosing?

300

It can be administered subcutaneously for slow release or ________ for faster action

What is intravenously?

400

The legality of EPO is best described as this—legal in healthcare but illegal in athletic competition without approval.

What is conditional (or dual) legality?

400

EPO is reinforcing in athletes because it improves this sport-related outcome.

What is performance?

400

This common cardiovascular effect of EPO misuse involves elevated blood pressure due to thicker blood

What is hypertension?

400

While EPO is highly effective at increasing red blood cell production, excessive potency can lead to hyperviscosity. A level above 50% is frequently used as a threshold by sports organizations to indicate potential EPO abuse.

What is Hematocrit?

400

This is the main effect that EPO has on the bloodstream

What is increased oxygen delivery to tissues through higher red blood cell production?




500

This organization was created in 1999 to standardize anti-doping rules worldwide after repeated EPO scandals.

With repeated EPO use, the body may reduce its own natural production in this organ.

What are the kidneys?

500

Long-term EPO misuse increases the risk of this dangerous condition, where blood clots can block vessels and lead to stroke or heart attack.

What is thrombosis?

500

The potency of EPO is measured by its effect on oxygen transport. Because of its extreme potency, EPO can increase a person's total hemoglobin mass by up to this percentage range, significantly boosting oxygen-carrying capacity (VO2 being the max) but also thickening the blood.

What is 5% to 20%?

500

Why might EPO’s effect on the blood stream be desirable?

What is better muscle endurance an less fatigue due to increased oxygen delivery to tissues?
