The Critical Distinction: Medical Treatment vs. Enhancement
It is crucial to differentiate between the legitimate, physician-supervised use of drugs to treat debilitating conditions and the often-illegal use of substances for athletic performance or aesthetic enhancement. Medically, certain drugs are vital for patients with muscle-wasting diseases (cachexia), age-related muscle loss (sarcopenia), testosterone deficiency, and delayed puberty [2.2.1, 2.2.3, 2.4.2]. In contrast, using these powerful compounds without a prescription, often at much higher doses, carries substantial and potentially life-threatening health risks [2.3.3]. This article examines the landscape of drugs that strengthen the body, focusing on their mechanisms, medical applications, and the significant dangers of their misuse.

Legitimate Medical Applications for Building Strength and Mass
Pharmacological intervention is a key strategy for combating conditions characterized by the loss of muscle mass and strength.
Treating Sarcopenia and Cachexia
Sarcopenia is the progressive loss of muscle mass and function associated with aging, affecting a significant portion of the elderly population [2.9.3]. Cachexia is severe body wasting associated with chronic illnesses like cancer [2.7.2].
- Testosterone Therapy: For men with clinically low testosterone (hypogonadism), replacement therapy can help restore muscle mass and strength [2.2.5, 2.6.5]. It is administered via injections, gels, or patches [2.8.4].
- Ghrelin Agonists: Anamorelin, a ghrelin agonist, stimulates appetite and has been approved in some regions for treating cancer cachexia by promoting increases in body weight and muscle mass [2.7.1, 2.7.5].
- Investigational Drugs: Research is ongoing for new treatments. Myostatin inhibitors like Bimagrumab and Apitegromab are being studied to block the signals that naturally limit muscle growth, showing promise in clinical trials [2.6.6, 2.8.5].
Other Medical Uses
- Anabolic-Androgenic Steroids (AAS): Though widely known for abuse, a small number of anabolic steroids are approved for medical use. They can be prescribed to treat conditions such as testosterone deficiency, delayed puberty, anemia, and tissue wasting from diseases like AIDS [2.2.1, 2.2.3]. Examples include testosterone, Nandrolone, and Oxandrolone [2.2.2, 2.8.2].
- Human Growth Hormone (hGH): Synthetic hGH is medically used to treat growth hormone deficiency in children and adults, muscle-wasting disease associated with HIV/AIDS, and short bowel syndrome [2.4.2, 2.4.3]. It works by stimulating the liver to produce insulin-like growth factor 1 (IGF-1), which promotes bone and muscle growth [2.4.1].
Performance Enhancement Drugs: High Risk, Illicit Use
This category includes substances used outside of medical supervision to increase muscle size, strength, and athletic performance. Their use is banned in competitive sports and illegal without a prescription [2.2.1, 2.5.2].
Anabolic-Androgenic Steroids (AAS)
AAS are synthetic variations of the male hormone testosterone [2.2.2]. They are the most well-known class of performance-enhancing drugs. By binding to androgen receptors in muscle cells, they stimulate protein synthesis, leading to increased muscle mass and strength [2.2.6]. However, their use is associated with a vast array of dangerous side effects.
- For Men: Shrinkage of testicles, reduced sperm count, infertility, baldness, development of breasts (gynecomastia), and increased risk of prostate cancer [2.2.2, 2.3.5].
- For Women: Deepening of the voice, growth of facial and body hair, male-pattern baldness, and clitoral enlargement. Many of these changes are permanent [2.2.2, 2.3.6].
- For Both: High blood pressure, heart attack, stroke, liver damage or cancer, high cholesterol, severe acne, and psychiatric effects like aggression, mania, and depression [2.3.3, 2.3.4].
Human Growth Hormone (hGH)
While it can increase lean body mass, research shows that in healthy adults, hGH does not necessarily improve strength and can worsen exercise capacity [2.4.1, 2.4.5]. Misuse carries serious risks, including nerve, muscle, or joint pain; swelling (edema); carpal tunnel syndrome; high cholesterol; and an increased risk of diabetes and cancerous tumors [2.4.2, 2.4.4].
Selective Androgen Receptor Modulators (SARMs)
SARMs are a newer class of compounds designed to have similar anabolic effects to steroids but with fewer androgenic side effects [2.5.2]. They are often illegally marketed online as "legal steroids" or "research chemicals" [2.5.3]. Examples include Ostarine (MK-2866) and Ligandrol (LGD-4033) [2.5.2]. Critically, no SARM is approved by the FDA for human use, and they are not legal dietary supplement ingredients [2.5.1, 2.5.2]. The FDA has warned they are associated with life-threatening health problems, including liver injury, increased risk of heart attack and stroke, and psychosis [2.5.1].
Comparison of Strength-Building Agents
| Agent Class | Medical Use | Illicit Use | Legal Status (US) | Key Risks of Misuse |
|---|---|---|---|---|
| Anabolic Steroids (AAS) | Testosterone deficiency, cachexia, delayed puberty [2.2.1] | Muscle mass, athletic performance [2.2.5] | Schedule III Controlled Substance; prescription required [2.2.1] | Liver damage, heart attack, stroke, hormonal disruption [2.3.4, 2.3.5] |
| Human Growth Hormone (hGH) | GH deficiency, muscle wasting in HIV/AIDS [2.4.2] | Anti-aging, muscle gain [2.4.4] | Prescription required; illegal for enhancement [2.4.4] | Increased cancer risk, diabetes, joint pain, carpal tunnel [2.4.2] |
| SARMs | None (Investigational) [2.5.3] | Muscle mass, fat loss [2.5.6] | Not approved by FDA; illegal to sell as supplements [2.5.1, 2.5.3] | Liver injury, heart attack, stroke, unknown long-term effects [2.5.1] |
Conclusion
While certain drugs play an indispensable role in strengthening the body for patients with specific medical conditions, their use must be strictly monitored by a healthcare professional. The allure of a shortcut to physical strength through illicit substances like anabolic steroids, misused hGH, or unapproved SARMs comes with a high price: a significant risk of severe, long-lasting, and potentially fatal health consequences. Legitimate and safe paths to building strength for most individuals remain rooted in consistent nutrition and proper exercise, not in unregulated chemical enhancement.
