Used in veterinary medicine to promote growth in livestock, particularly in beef cattle. It acts as a hormone implant that enhances feed efficiency, weight gain, and muscle development. Commonly administered in the form of pellets implanted under the skin behind the ear. Its use is regulated in many countries due to concerns about hormone residues in meat, and it is banned in certain regions like the European Union. Also studied in research settings for hormonal effects, though not used in human therapy.
