Medications and Athletes: How Common Drugs Affect Performance and Health

Every year, thousands of athletes-elite and weekend warriors alike-take medications hoping to gain an edge. Some are prescribed legally. Others are bought off the internet or from gym buddies. But what most don’t realize is that many of these drugs don’t just boost performance-they come with serious, sometimes permanent, damage to the body.

What Are Performance-Enhancing Drugs, Really?

Performance-enhancing drugs (PEDs) aren’t just about steroids. They include stimulants, human growth hormone, blood doping agents, and newer compounds like SARMs. These aren’t magic pills. They’re powerful chemicals that force the body to change how it functions. Anabolic steroids, for example, mimic testosterone to push muscle growth beyond what natural training can achieve. Stimulants like amphetamines or high-dose caffeine speed up the nervous system to sharpen focus and delay fatigue. Blood doping increases red blood cell count to carry more oxygen to muscles during endurance events.

The results can be dramatic. In just 6 to 12 weeks, users may gain 10 to 20% more muscle mass than they ever could naturally. Recovery times shrink by 30 to 50%. Endurance athletes see VO2 max improvements of 5 to 15%. But these gains come at a cost most people ignore until it’s too late.

The Hidden Health Costs of Steroids

Anabolic steroids are the most common PEDs used today-making up 75% of the underground market. But their side effects aren’t just rumors. Medical studies show real, measurable damage.

Men who use steroids regularly often see their testicles shrink to half their normal size. Sperm counts drop below 1 million per milliliter-far below the healthy threshold of 15 million. In 90% of cases, natural testosterone production shuts down after just 8 weeks of use. Recovery can take 6 to 12 months… if it happens at all. About 38% of long-term users end up needing lifelong testosterone replacement therapy.

Women face irreversible changes: voice deepening in 35% of cases, clitoral enlargement, and facial hair growth. These effects don’t go away after stopping use.

Cardiovascular damage is the most dangerous. Studies show steroid users have 27 to 45% more heart muscle mass than non-users-even after accounting for body size. This thickened heart doesn’t pump as efficiently. Ejection fractions drop by 8 to 12%. The American Heart Association confirms steroid use increases the risk of major cardiac events by 36%. There are documented cases of heart attacks in athletes under 30 with no prior health issues.

Stimulants: Fast Gains, Faster Risks

Stimulants like ephedrine, amphetamines, and even high-dose caffeine give athletes a quick boost. Reaction times improve by 8 to 12% within 30 minutes. Energy spikes. Fatigue fades. But the margin for error is razor-thin.

The Mayo Clinic reports over 2,000 emergency room visits each year in the U.S. from energy drink overdoses-many from athletes trying to replicate the effects of banned stimulants. Heart palpitations, high blood pressure, and arrhythmias are common. In extreme cases, these drugs trigger strokes or sudden cardiac arrest.

And the mental toll is severe. Eighty-three percent of recreational users report extreme mood swings. Two-thirds experience clinical depression during “off-cycles” when the drug leaves their system. One Reddit user wrote: “I gained 25 pounds of muscle in 10 weeks. Then I lost it all in 8 weeks-and couldn’t get out of bed for months.”

Blood Doping: The Silent Killer

Blood doping-whether through transfusions or drugs like EPO-boosts oxygen delivery to muscles. Elite cyclists and distance runners have used it for decades. The performance gains are real: VO2 max increases of up to 15%.

But when hematocrit levels rise above 50%, the blood thickens. It doesn’t flow well. The risk of stroke or pulmonary embolism jumps sevenfold. There are no warning signs. One athlete feels fine, then collapses during training. No history of heart disease. No family risk. Just overused blood.

Unlike steroids, blood doping doesn’t cause hormonal chaos. But it’s far deadlier in the short term. That’s why it’s banned outright-and why WADA spends millions testing for it.

The Myth of “Safe” Alternatives

SARMs (selective androgen receptor modulators) are marketed as the “safer steroid.” They promise muscle gain without the side effects. But here’s the truth: 89% of SARMs products sold online contain something else entirely. The FDA tested hundreds of these supplements. Many had undisclosed steroids, stimulants, or even cancer-causing chemicals.

And they’re not tested for long-term safety. No one knows what 5 years of SARM use does to the liver, heart, or hormones. Yet they’re everywhere-in fitness forums, supplement stores, and Instagram ads. Athletes think they’re being smart. They’re not.

Why Doctors Miss the Signs

Most athletes never tell their doctor they’re using PEDs. A 2021 study found that 42% of recreational users take these drugs-but only 12% mention it during checkups.

Why? Because doctors aren’t trained to ask. And the symptoms don’t always look like classic drug abuse. Low testosterone? “Just stress.” Mood swings? “Depression.” High blood pressure? “Genetics.”

Dr. Michael Lombardo of the American Academy of Family Physicians says, “Seven out of 10 family physicians don’t recognize PED use in their patients.” By the time symptoms are obvious, the damage is often irreversible.

What Happens When You Stop?

Many users think they can just quit after a cycle. They do “post-cycle therapy” with supplements or low-dose hormones to kickstart natural testosterone. But it doesn’t always work.

Research shows 62% of users who try to recover naturally still have low testosterone after 6 months. Some never fully recover. Their bodies forget how to make testosterone on their own.

And muscle loss hits fast. Without the drug’s artificial boost, muscle tissue breaks down. Strength plummets. Fat returns. Many users cycle again-not because they want to, but because they feel worse without it.

Who’s Really Using These Drugs?

It’s not just Olympians. Elite athletes make up only 15 to 20% of PED users today. The majority-65 to 70%-are recreational gym-goers. People who lift weights on weekends. Parents trying to get “jacked” for summer. Men in their 30s and 40s chasing a lost physique.

Even teenagers are affected. Between 2018 and 2022, pediatric cases of steroid-induced heart damage increased 200%. Kids as young as 14 are showing up in ERs with cardiomyopathy.

And it’s getting easier to get these drugs. Online vendors sell them as “research chemicals” or “not for human consumption.” Wellness clinics offer “bio-identical hormone therapy” that includes banned substances. No prescription needed. No questions asked.

The Bigger Picture

WADA updates its banned list every year. In 2023, three new SARMs were added. But the underground market evolves faster. New compounds appear before labs can detect them.

Testing catches less than 1% of users. That’s not because the tests are bad-it’s because so many people are using. And society’s attitude is shifting. A 2023 University of Michigan study found 58% of gym-goers have no moral problem with PEDs if they’re not competing.

That’s dangerous. Because the risks aren’t theoretical. They’re documented. In hospital records. In autopsy reports. In patient testimonials.

There’s no shortcut to real strength. No pill that replaces years of training, sleep, and nutrition. What drugs give you is temporary. What they take away? Could last a lifetime.

What Should You Do Instead?

If you’re looking to improve your performance, the best path isn’t through a needle or a pill. It’s through consistency. Train smart. Eat enough protein. Sleep 7-9 hours a night. Track your progress. Give your body time to adapt.

Real strength doesn’t come from chemicals. It comes from showing up day after day-even when you don’t feel like it. The body adapts slowly. But when it does, the gains last. No crash. No depression. No hospital visits.

There’s no shame in wanting to get stronger. But there’s huge risk in taking shortcuts that could cost you your health, your future, and your freedom to move without pain.
