Description:

Mibolero is a veterinarian grade anabolic steroid that was released in the 1960's by Upjohn under the brand name Cheque Drops and later as Cheque Medicated Dog Food. The purpose of this steroid is to disrupt the menstrual cycle of a female dog in order to prevent pregnancy. As with many steroid hormones, and this includes veterinarian grade, it wasn't long after its inception that athletes and bodybuilders found a use. 

Applications:

1.Under the brand name "Cheque Drops", Mibolerone Acetate 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.

2.Nandrolone appears to be used to make Mibolerone. For comparison, also see bolasterone and calusterone.

3.Studies have been difficult to perform due to the known high toxicity levels of the drug, and lack of pragmatic use in humans.  One study in humans indicated potential altered liver function so the study was immediately ceased.

4.In rats, Mibolerones has been shown to be both highly anabolic and androgenic.   It was found to be 41 times more anabolic and 16 times more androgenic than methyltestosterone.  No estrogenic activity in mice was reported when when 1.0 mg per animal per day was administered.  It was also found to be anti-estrogenic in mice 10 mcg or less when subcutaneously tested against estradiol.  A dose of 1,600,000mcg/kg was fatal in 50% of the rats.
