Chemical Composition and Structure
Boldenone undecylenate is a synthetic steroid derived from testosterone. It is characterized by the presence of the undecylenate ester, which gives it a long half-life of up to 1.5 years. Due to its long half-life, trace amounts of Boldenone undecylenate can be detected in biological samples for several months after discontinuation of use.
Usage in Livestock
Widely used in livestock under various trade names such as Equigan, Equipoise, Ultragan, and Ganabol.
Used to enhance growth and feed conversion in beef cattle, veal calves, and broilers, leading to more effective meat production.
Anabolic Effects
Enhances muscle size through hypertrophy and hyperplasia.
Promotes positive nitrogen balance by stimulating protein production and reducing protein degradation.
Facilitates retention of nitrogen, water, and electrolytes.
Regulatory Status and Health Risks
Classified as a probable human carcinogen (Class 2A) by the International Agency for Research on Cancer (IARC).
European Community banned its use as a growth-promoting agent in livestock breeding due to health risks.
