Cheque Drops Mibolerone

If steroids were held to a certain level of performance, there would be nothing better than cheque drops, thanks to their performance in the body of an athlete. Cheque drops were first used by breeders of all kinds and mainly dog breeders. The work of cheque drops on dogs is to regulate the heat cycles of bitches and thereby keeping the breeding of dogs in check. Breeders are able to regulate the number of dogs they have in their pens and the quality of puppies produced when they reproduce.

After some time of use on animals, cheque drops were used on humans; especially athletes. It is said to be one of the best steroids in the world for its ability to increase the aggression of athletes when preparing for a match. This way, despite the surrounding conditions an athlete is able to train well and deliver good performance in the sport.

If you have been in competitive sports for some time you know the importance of being aggressive in the sport. Natural aggressiveness is not good enough in sport. Sometimes it can get hard to train, especially when you are surrounded by people who seem to be enjoying their lives while you have to train. Training for a competition can be hard too if you do not have the support of your surrounding people or you do not have company. Cheque drops eliminate the need for any kind of support and makes sure you are as aggressive as possible in readiness for the match.

Cheque drops are androgens that are five times as active as testosterone. If you have been on testosterone-based steroids, and enjoyed the kick that comes with it, imagine what it will feel like to be on a steroid that is five times more aggressive than the testosterone-based steroids. Cheque drops are used by boxers and bodybuilders and are great for aggression, which will lead to strength building and packing of muscles.

As for the side effects, this is one of the most toxic steroids, with dangerous side effects. The standard time for the use of cheque drops is two weeks and if used for more than two weeks, you will be inviting health problems. The aggressiveness brought about by cheque drops can be too much that you may find it hard to sleep. This is insomnia; and it is expected to clear as soon as you are through with the drug, if it does not, you need to consult a physician.

Cheque drops suppress the production of natural testosterone in the body and can cause extensive liver damage if used constantly. Because it is used for only two weeks, you can expect fast results in any upcoming competition. Nonetheless, you will have to deal with hypertension and this is made worse if you started using cheque drops when dealing with hypertension. It does not aromatize, so you can heave a sigh of relief since the muscles will not have water retention. Men will experience the development of breast tissue with the long term use of cheque drops.

by Anthony Roberts - 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. Cheque drops provide a short adrenaline-like aggression rush in athletes when used immediately prior to a sporting event. Due to its high androgenic properties, it is often the cause of progesterone related gynecomastia.


Cheque Drops are manufactured by Upjohn. Mibolerone powder is produced by three Chinese labs currently. A few underground labs produce the compound as well; including Supra, who is currently number one in Cheque Drop production.

Steroid Action

Due to the short half-life of Mibolerone, it is most commonly used by athletes about 30-40 minutes before their sporting event. Cheque drops are placed under the athletes tongue, and effects including aggression, strength and adrenaline rush are felt rapidly. The drug leaves the body with in approximately four hours.

As well as being one of the most androgenic compounds, mibolerone is also one of the most toxic. The most common side effect is progesterone related gynecomastia because it is a 19 nor-androgen. It can also severely affect liver function because it is a 17AA compound. Use with other 17AA compounds can be extremely damaging to the liver. If used in low doses (less than 2 weeks), there are very few, if any anabolic effects. When used short term, natural testosterone will return to normal levels very quickly. However, if use surpasses 2 weeks there is an extremely high risk for liver damage and natural testosterone suppression because it is an LH blocker. Also, this compound does not convert into estrogen; therefore, progesterone production is increased.

Known side effects of the compound are increased aggression, disturbed sleep patterns or insomnia, high blood pressure and severe liver damage. It is highly dangerous if used by females. Some female side effects include severe acne, cessation of the menstrual cycle, deepening of the voice, clitoral enlargement and vaginal secretion. Effects of the drug will also be passed onto an unborn fetus.

Technical Data

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(1).

In rats, Mibolerone 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 (1).

User Notes

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.

Mibolerone is the chemical name of active ingredient in Cheque Drops. Cheque is a registered trademark of Pharmacia & UpJohn in the United States and/or other countries.

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 we’re talking about, that won’t 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 don’t 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.

Female athletes should avoid this compound at all costs. Remember, it’s 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 that’s 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 wasn’t slang; it’s 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. Let’s 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! You’d 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.

Cheque Drops Characteristics
This is without a doubt the most powerful steroid that was ever commercially marketed. Its androgenic potency is slightly less than that of methyltrienolone, but it can still aromatize, adding the benefits of estrogen as well. Unfortunately the only product it was ever marketed as never fully exploited the potential of this drug. It was delivered in microgram amounts in liquid droppers, the intent being to add a few drops to the food of female dogs in heat to keep them under control. Human athletes used a few drops under the tongue before a sporting event or training to increase their aggression levels, but noted little or no anabolic effect from this drug because it was so lowly dosed. Not that there was much room for high doses, because even in these low amounts using it longer than 2 or 3 weeks on end seemed to seriously compromise your liver. Just to demonstrate quite how toxic the compound mibolerone was to humans.

If it was free and safe to use orally, just 5 mg per day would probably give you more anabolic effect than a high-dose stack of several of the strongest products out there. It wasn’t that far in potency from methyltrienolone. It possessed the same androgenic binding of trenbolone, even more so because its affinity for binding structures was even more reduced due to its 17-alpha-alkylation. But unlike methyltrienolone, it still allowed for aromatization to testosterone, enhanced by the progestagenic effect that all 19nor compounds seem to possess, which only further enhanced the extreme anabolic effect of mibolerone. Unfortunately because of its 17-alpha-alkylation it also rivaled methyltrienolone (metribolone) in liver toxicity, making it completely unsafe to even use 5 mg a day without killing yourself short term. A much better choice in that regard would have been trestolone (MENT), which is the same as Mibolerone but doesn’t possess the toxic 17-alpha-methyl group. Sadly enough, MENT was never commercially marketed despite its well documented use as a male contraceptive (same for Mibolerone as well by the way).

But bodybuilders and other athletes had to make do with low-dosed cheque drops to increase activity. Nonetheless they enjoyed a great popularity. Mostly owed to the late Steroid guru Dan Duchaine. This was one of his many obscure (and usually dangerous) discoveries. The same person that discovered DNP, and extremely hazardous and powerful fatburner. Oddly enough cheque drops were more popular outside of bodybuilding. Boxers, football players and martial artists who fought full contact particularly had a fondness of this product and used it to enhance aggression prior to an important match with great success. It wasn’t seldom that when a particularly aggressive incident occurred in boxing, that it was rumoured Mibolerone was the real culprit.

But even that didn’t last, cheque drops have all but disappeared and I have yet to come across a legit one, or even an empty packaging from a legit one a long time ago. Which would illustrate what a dinosaur cheque drops have become in such a short time. But for those who really look around, they are still out there and I believe in some countries still used in veterinary medicine. So if you want it bad enough, but like I said, its impossible to use it to its full capacity, so its probably a waste to pursue anyway.

Stacking and Use
Because its extremely toxic in higher doses and cannot be used longer than 2 weeks on end, there really isn’t much to stack with cheque drops. A user will opt to take but a few drops sublingually (under the tongue) prior to an event for which he requires and increase in energy and aggression. But because here too there is the risk of natural testosterone suppression, cheque drops are best used during a cycle with other anabolic steroids. In this nature it stacks with literally everything however, and is both suited for use during bulking as well as cutting, eventhough it doesn’t have a direct influence on either.

Because it’s a non-aromatizing steroid that cannot be used longer than two weeks, the post-cycle use of Clomid or Nolvadex is not required. Natural test will only partially be suppressed and should bounce back. If as advised you stacked it with a longer cycle of other steroids, its imperative that you still run them because of these other steroids, not so much for the cheque drops. For those prone to hypertension the use of an anti-hypertensive agent like Catapresan would be advised however. No other ancillaries should be required with this agent.

I wish I had known it was such a great product back in the 90's I had a Vet hook up for almost 9 yrs and I could get a bottle for $20.00... I infact got a guy a cple bottles tgen found out after he was injecting it instead of using the dropper... Since he was obviously an idoit I had to cut him off... Losing 18 bottles of Winstrol V and Equipoise was too good a thing to risk losing as it was. I tried about half a bottle of Cheq before stopping. I had so much other gear I was more familar with so I trashed it not knowing what I had...

09-01-2013, 06:40 PM
Man BN I want to try them and our sponsor has them on the site but says out of stock. So basically they don't have any LOL. I would buy them asap if they got some in.

They (the guys in the gym) called it liquid anadrol... As much as I loved anadrol I still wasnt gonna inject any of it in my hip. I dont recall it being in the pharmacutical basics of theraputics I had my face buried in all the time.... So I ditched it under the impression it was too toxic. I just recently found out what I had but UpJohn no longer produces it. $20.00 a bottle Shheeesh! A big bottle at that.
