Cheque Drops (Mibolerone)


<-- Return to Main Profiles Page

Mibolerone was initially as a veterinary product used to keep female dogs under control while they are in heat by shutting down the cycling of their ovaries. With proper timing, breeders are able to regulate the heat cycles of their bitches. Eventually, athletes began to utilize the product in order to boost aggression before events. It was even rumored that Mike Tyson was on Cheque Drops during the infamous ear biting incident during his bout with Holyfield. However, the late great guru Dan Duchaine discovered the application of Cheque Drops in modern bodybuilding far before that. The drops went in and out of production several times, before making a recent insurgence due to the piqued interest in the product thanks to the growing popularity of ultimate fighting circles.


Cheque Drops are extremely potent, certainly one of the most potent androgens known to man. According to the manufacturer, "When compared to testosterone, it is 5.9 times more potent as an anabolic agent and 2.5 times more potent as an androgen." The most probable usage for Cheque Drops is for administration to athletes 30 to 40 minutes prior to an event that requires extreme aggression and adrenaline. To adapt the drug to bodybuilding purposes requires a much more complicated dosing regimen. Due to its toxicity, Cheque Drops should not be used longer than two weeks at a time, and at low dosages. However, for an anabolic effect, Cheque Drops should be used at 5mg (5,000mcg) a day or more. However, that would possibly lead to prompt physical illness. In order to find a medium that is possible for the modern bodybuilder, it is important to remember a few key aspects of the compound. Keep in mind that the dosages appropriate are only used to increase aggression, which can subsequently increase strength. The actual anabolic effect at these low doses is limited. Furthermore, long term use (beyond two weeks) will lead to testosterone suppression and liver damage. Using the drops sparingly (1-2 drops at a concentration of 200-250mcg 30 minutes prior to a workout for no more than 2 weeks at a time) will provide a boost in training and aggression. Many users report breaking personal lift records when utilizing the compound. If the drops are used short term, testosterone levels should bounce back rather quickly. However, due to the risk of suppression, it is best to use the drops while on an anabolic stack in order to ensure elevated test levels. As the drops are only used as a supplement to lifting, they can be used when bulking or cutting. I would never recommend using this stuff without other compounds; however, the increased aggression without the increased performance provided by other compounds may be dangerous. They do not aromatize (convert to estrogen), so if used in the context above, Nolvadex, Armidex, or other such agents are not necessary, nor is the use of Clomid. It is highly progestenic, but in the doses were talking about, that wont be a concern either. Unfortunately, this stuff blocks LH secretion, which will wreak havoc with your natural hormone production with prolonged use.

The half-life of the compound is very short (about 4 hours), so along with its immediate impact on the body, it leaves quickly as well. The drug has had enough of an impact, however, to be included in most all banned substance lists in most athletic organizations, so precaution should still be utilized. Several metabolites of this compound may still be detectable however (J Vet Pharmacol Ther. 2000 Apr;23(2):57-66.), if you are tested immediately.

While it is sometimes touted as the most androgenic compound on the planet, it might subsequently be the most toxic as well. A 19 nor-androgen it can possibly cause progesterone related gynocomastia (you dont want that) if used out of the recommended dosage and time frame. A 17AA compound, it can also severely affect liver function. Precaution MUST be used when dealing with Mibolerone. Side effects include but are not limited to: increased aggression, hypertension, insomnia, and severe liver damage.

Cheque Drops for Dogs

Female athletes should avoid this compound at all costs. Remember, its used to regulate ovulation in bitches (ok that was a gratuitous use of that word again).

Side effects include but are not limited to: severe acne, deepened voice, as well as depression of menstruation and clitoral enlargement and err vaginal secretion (if thats an issue ). If taken by a pregnant female athlete, it would have possible effects on the fetus, as well as alter serum lipids. Remember, this stuff is used to control bitches in heat (and no, that wasnt slang; its really used to control female dogs that are ovulating).

For those that are naturally aggressive, this compound will elevate aggression to dangerous levels. It may affect some users more severely than others, and should the athlete still be experiencing elevated aggression levels after the estimated time of physical exertion; they may displace aggression on others. Cheque Drops should not be stacked heavily with other 17AA compounds. Lets be honest, though .this stuff is powerful, but not deadly. The LD50 (the dose at which 50% of the lab rats died) is 1,600,000mcg/kg! Youd need to take bottles and bottles of this stuff per day, to replicate anything nearing that dose.


Cheque Drops are manufactured by Upjohn, and available in a 100 mcg per cc, 55-cc bottles. There are 3 Chinese manufacturers of Mibolerone powder, which offer the crystalline form for anywhere between 200-350 dollars/gram. Several underground labs have also begun to produce Cheque Drops, such as Supra, with a concentration of 200mcg/ml, but the prices remain high, and the availability low. Currently, Supra is the leader in Cheque drop production for athletes today.
