Anabolic – Meaning, Hormones and Risks
Anabolic refers to metabolic processes in which the body builds up tissue, especially muscle mass. Anabolic substances actively promote this tissue-building process.

Anabolic refers to metabolic processes in which the body builds up tissue, especially muscle mass. Anabolic substances actively promote this tissue-building process.
What does anabolic mean?
Anabolic describes all biochemical processes in the body that promote the building up of body tissue – as opposed to catabolic processes, which involve the breakdown of tissue. The term originates from the Greek word anabole (meaning ascent or building up) and is a fundamental concept in biochemistry, sports medicine, and pharmacology. Anabolic processes are essential for life: they enable growth, tissue repair, and the formation of proteins, hormones, and other bodily structures.
Anabolism in Metabolism
Anabolism is one of the two sides of metabolism. It encompasses all reactions in which complex structures are built from simpler molecules. Key anabolic processes include:
- Protein synthesis: Building muscle proteins from amino acids
- Glycogen synthesis: Storing glucose as glycogen in the liver and muscles
- Lipogenesis: Formation of fatty acids and body fat
- Cell growth and division: Building new cells and tissues
Anabolic processes require energy, which is supplied in the form of ATP (adenosine triphosphate).
Anabolic Hormones
Certain hormones naturally promote anabolic processes in the body:
- Testosterone: The primary anabolic sex hormone, promotes muscle growth and bone density
- Growth hormone (HGH): Stimulates cell growth and tissue repair
- Insulin: Promotes the uptake of glucose and amino acids into cells
- IGF-1 (Insulin-like Growth Factor 1): Supports muscle and bone growth
Anabolic Steroids
Anabolic steroids (colloquially: anabolics) are synthetically produced substances that mimic the effects of testosterone. They are used medically in cases such as:
- Muscle wasting (e.g., in chronic illness or following surgery)
- Delayed puberty
- Certain forms of anemia
- Osteoporosis (in some countries)
In sport, anabolic steroids are misused to increase muscle mass and performance. This is banned in competitive sports and can carry significant health risks.
Risks and Side Effects of Anabolic Steroids
Improper or abusive use of anabolic steroids can lead to serious side effects, including:
- Cardiovascular damage: Enlarged heart, increased risk of heart attack, high blood pressure
- Liver damage: Especially with oral forms
- Hormonal disorders: Testicular atrophy, infertility, gynecomastia (breast tissue development in men)
- Psychological effects: Aggression, mood swings, dependency
- In adolescents: Premature growth arrest due to early closure of growth plates
- In women: Virilization, menstrual irregularities
Anabolic Nutrition and Sport
In sport and fitness, the term anabolic is frequently used in connection with measures that promote muscle growth. These include:
- Adequate protein intake (approximately 1.6–2.2 g per kg of body weight per day for strength athletes)
- A caloric surplus to support muscle building
- Resistance training as the strongest natural stimulus for anabolism
- Sufficient sleep, as growth hormone is primarily released during sleep
Anabolism and Catabolism in Balance
A healthy metabolism requires a balance between anabolism and catabolism. When anabolism predominates, tissue grows (e.g., muscle gain or fat accumulation). When catabolism predominates, tissue breaks down – which can occur during illness, malnutrition, or intense endurance exercise. The goal of a healthy lifestyle is to optimize this balance according to individual needs.
