Uses of Mibolerone: It is originally used to suppress ovulation of female dogs in heat, Mibolerone is one of the most harsh steroids in existence. It is approximately 5.9 times as anabolic, and 2.5 times as androgenic as Testosterone. Due to its high androgenic properties, it is often the cause of progesterone related gynecomastia. This is really nasty stuff. Basically, it's only good for increasing aggression just prior to an athletic event or before an intense training session. For most athletes, Methyltestosterone, Testosterone Suspension, or Halotestin is typically preferred for this purpose because Cheque Drops are rarely found on the black market.
