Mibolerone is a potent anabolic steroid which is both higher affinity and more selective for the androgen receptor than metribolone.
Under the brand name "Cheque Drops", Mibolerone was marketed as a veterinary drug by the Upjohn company. It was indicated as an oral treatment for estrous (heat) prevention in adult female dogs.
