Estradiol benzoate
Estradiol benzoate is available in Europe and in other parts of the world. It was previously available for medical use in the United States, but is no longer marketed in this country. However, it is approved and marketed in the United States for veterinary use as a subdermal implant both alone and in combination with the androgen/anabolic steroid trenbolone acetate (brand names Celerin and Synovex, respectively). Outside of the United States, estradiol benzoate is also marketed in combination with progesterone for use as an intramuscular injection.
