Athletes constantly seek ways to improve strength, endurance, and recovery. Performance-enhancing drugs (PEDs) like anabolic steroids, human growth hormone (HGH), and EPO have gained popularity for their ability to boost muscle growth, increase stamina, and enhance oxygen delivery. While these substances may offer competitive advantages, they come with risks, including health complications and legal consequences. Understanding the effects, benefits, and potential dangers is crucial for athletes looking to optimize performance safely and ethically.
