Which peptide hormone is used to build muscle and aid recovery?

• A. EPO
• B. HGH
• C. PEDs
• D. Beta blockers

Answer: (B)

Muscle growth and recovery depend on hormones that drive protein production and tissue repair. Human growth hormone is a peptide hormone from the pituitary that boosts the production of IGF-1, which enhances amino acid uptake and protein synthesis in muscles, leading to increased muscle mass. It also supports collagen formation and tissue repair, helping recovery after exercise or injury. This combination makes it the best fit for both building muscle and aiding recovery among the options. EPO increases red blood cell production to improve endurance, not muscle growth. Beta blockers affect heart rate and steadiness, not muscle development. PEDs cover a wide range of substances, but the question points to a peptide hormone, and human growth hormone is the one that matches.
