1 of 3

• Testosterone serves as the primary anabolic steroid, naturally produced in the body
• Dianabol (methandrostenolone) promotes rapid muscle mass gains and strength increases
• Deca-Durabolin (nandrolone decanoate) aids in joint pain relief and muscle growth
• Winstrol (stanozolol) enhances speed, strength, and lean muscle mass without significant water retention
• Trenbolone exhibits powerful anabolic effects, improving muscle hardness and vascularity

Natural vs synthetic steroids

• Natural steroids originate from biological sources, produced by the body or derived from plants
• Testosterone, secreted primarily by the testes in males and ovaries in females, functions as the principal natural anabolic steroid
• DHEA (dehydroepiandrosterone) acts as a precursor to testosterone and estrogen, produced by the adrenal glands
• Synthetic steroids result from laboratory modification of testosterone or other steroid molecules
• Synthetic variants often exhibit enhanced anabolic properties and reduced androgenic effects compared to natural steroids
• Molecular alterations in synthetic steroids aim to improve oral bioavailability and extend half-life in the body

Physiological effects

• Anabolic steroids exert profound effects on the human body, particularly on muscle tissue and overall physical performance
• In sports medicine, understanding these physiological effects aids in assessing potential benefits and risks for athletes
• The impact of anabolic steroids extends beyond muscle growth, affecting various organ systems and metabolic processes

Muscle growth mechanisms

• Anabolic steroids increase protein synthesis in muscle cells, promoting muscle hypertrophy
• Enhanced nitrogen retention leads to improved muscle recovery and growth
• Steroids stimulate the production of insulin-like growth factor 1 (IGF-1), further promoting muscle development
• Increased red blood cell production improves oxygen delivery to muscles, enhancing endurance and recovery
• Steroids inhibit the catabolic effects of cortisol, reducing muscle breakdown during intense training

Strength and performance enhancement

• Anabolic steroids significantly increase muscle strength, often exceeding natural physiological limits
• Enhanced muscle power output improves athletic performance in explosive activities (sprinting, weightlifting)
• Increased muscle endurance allows for longer and more intense training sessions
• Faster recovery between workouts enables more frequent and intense training
• Improved body composition, with increased lean muscle mass and reduced body fat percentage

Effects on other body systems

• Cardiovascular system: Potential increase in blood pressure and alterations in cholesterol levels
• Liver function: Hepatotoxicity risk, especially with oral steroids, due to increased liver enzyme production
• Endocrine system: Suppression of natural testosterone production and potential disruption of hormonal balance
• Skeletal system: Accelerated bone maturation in adolescents, potentially stunting growth
• Skin: Increased sebum production leading to acne, potential hair loss or excessive body hair growth

Medical uses

• Anabolic steroids serve important therapeutic roles in various medical conditions, highlighting their legitimate use in healthcare
• In sports medicine, understanding the medical applications of steroids aids in differentiating between therapeutic use and performance enhancement
• Proper administration and monitoring of anabolic steroids in medical settings minimize potential side effects while maximizing therapeutic benefits

Treatment of muscle wasting

• Anabolic steroids combat muscle wasting associated with chronic diseases (HIV/AIDS, cancer)
• Administration improves lean body mass and overall strength in patients with severe muscle loss
• Dosage and duration carefully monitored to optimize muscle preservation while minimizing side effects
• Combined with nutritional support and physical therapy for comprehensive treatment
• Specific steroids (oxandrolone) approved for treating muscle wasting conditions

Hormone replacement therapy

• Testosterone replacement therapy (TRT) treats hypogonadism in males
• TRT aims to restore physiological testosterone levels, improving libido, energy, and muscle mass
• Various administration methods available (injections, gels, patches) tailored to patient needs
• Careful monitoring of hormone levels and potential side effects throughout treatment
• In some cases, anabolic steroids used to treat delayed puberty in adolescent males

Abuse in sports
