Question

which are classified as performance-enhancing drugs? select three options. vitamins protein powders steroid precursors anabolic steroids human growth hormone

Explanation:

Performance - enhancing drugs (PEDs) are substances used to improve athletic performance. Vitamins are essential nutrients for normal bodily functions, not PEDs. Protein powders are dietary supplements to support muscle growth but not classified as PEDs in the same way as the others. Steroid precursors can be converted into anabolic steroids and enhance performance. Anabolic steroids are well - known PEDs that promote muscle growth. Human growth hormone is also used as a PED to enhance performance by promoting growth and recovery. So the three are steroid precursors, anabolic steroids, and human growth hormone.

Answer:

C. steroid precursors, D. anabolic steroids, E. human growth hormone
