Mibolerone Cheque

An extremely powerful steroid approved only for veterinary use (suppressing heat cycles in female dogs), never approved for people. There's no legitimate human research on it, and its known animal-use potency suggests significant risk if taken by a person.

Also known as Cheque Drops, Mibolerona, Cheque, Matenon, Dihydrolone, Miboleronum, Mibolerone ciii
