Anabolic Agents

Anabolic steroids, or anabolic-androgenic steroids (AAS), are a class of steroid hormones related to the hormone testosterone. They increase protein synthesis within cells, which results in the buildup of cellular tissue (anabolism), especially in muscles.

Hormones and Related Substances

Hormones are chemicals that are released by the cells of the body in order to regulate the metabolism of those cells. A few types of hormones used in doping abuse include: Growth Hormone (GH), Insulin-like Growth Factors, and Erythropoiesis-Stimulating Agents.

Beta-2 Agonists

A bronchodilator medicine that opens the airways by relaxing the muscles around the airways that may tighten during an asthma attack or in COPD (chronic obstructive pulmonary disease). Beta-agonists can be administered by inhalers or orally.

Hormone Antagonists and Modulators

An antagonist is the opposite of an agonist which stimulates an action. Antagonists and agonists are key players in pharmacology and in the chemistry of the human body. For example, Selective Estrogen Receptor Modulators, Aromatase Inhibitors and Agents modifying myostatin functions.

Diuretics and Other Masking Agents

Anything that promotes the formation of urine by the kidney. For example Furosemide is a potent diuretic (water pill) that is used to eliminate water and salt from the body.

Stimulant

Stimulant drugs are drugs that temporarily increase alertness and awareness. They usually have increased side-effects with increased effectiveness, and the more powerful variants are therefore often prescription medicines or illegal drugs.
