Is Kenoselen A Steroid, And Is That The Reason My Roommates Boyfriend Is Getting Irritable Close To Contest Day?

My roommate's boyfriend is taking some kind of steroid called Kynoselen. She told me that she found this stuff in his apartment. When it gets close to a contest he gets real irritable and will do things like only eat the food he cooks. They never do stuff cause he is training or cooking or too tired. Do you think that this stuff is making him mean? What does it do? K.L.

I researched this one in depth-ly and the only "reputable" sources I could find claim that kynoselen AKA Kyno is not a steroid. Research as always is quite scant in the "hush-hush" world of bodybuilding secretes and the association with drug use and the sport. This first bit of info comes from Paul Cribb, a research scientist connected with the AST supplement company. I spoke adamantly about him my dissertation presentation when I graduated from my Dietetic Internship Program in May of 2003. I have ample respect for him he really knows his stuff. Off of the AST FAQ page I found this info.

  1. Kynoselen is not a drug; it is however a veterinarian quality injectable vitamin/mineral supplement. It contains potassium, Adenosine mono-phosphate (AMP), magnesium, and B-12. The vitamins/minerals in Kyno are important possess no performance enhancement abilities. It appears as if the AMP is the misunderstood component of Kyno.

Paul Cribb stated that a supplement company that he did not name markets the US version of Kynoselen. This company claims that AMP regulates protein synthesis, which is false.

Kyno is expensive, and a decent multi-vitamin/mineral supplement would be more potent and economical. Paul recommends that your roommate's boyfriend should save his cash because the claims concerning Kyno are "pathetic". He goes on to say that it is "one of the lamest marketing attempts" that he has seen in quite a while!

Now, keep in mind that he does not mention the ingredient HEPTAMINOL, why…. I do not know. Perhaps the U.S. version, which he spoke of, does not have Heptaminol in it and therefore making AMP the chief ingredient in the U.S. version. Other versions DO claim to have Heptaminol in them. This ingredient, after conducting an extensive Medline/Infotrac (peer reviewed journal articles) search appears to have somewhat of a hypotensive (lowers the blood pressure) property.

This claim however is still controversial. Heptaminol was also used as a psycho stimulant/antidepressant in treatment programs. Several "steroid" users report feeling great while cycling anabolic compounds such as anabolics…interestingly though this drug is not anabolic and as Paul stated it is merely more of a multivitamin on steroids.

Below is info I found regarding what it is supposed to be used for. Here are some indications and dose recommendations notice how none are converted for human use. Furthermore, it appears that they are injecting the stuff in the anterior region of the neck in some cases (as well as other places but still!!!).

"Administer in the anterior half of the neck in food producing animals".

Ultimately, I would never put this into my body! Sure some athletes go to the "extremes" to win but this stuff is far fetched and only sounds dangerous!

KYNOSELEN, valuable whenever cardiac/skeletal muscles are compromised via disease, deficiencies, or exhaustion. It can also be used when general stimulatory, restorative, or `tonic' effects are desired. May be helpful when debility and strength decrease are present.

* Myopathies & muscular degeneration, white muscle disease, selenium deficient myopathies, hypocalcaemic & hypomagnesaemic metabolic diseases in cows, tying-up syndrome of horses, post-race or strenuous activity, cobalt & vitamin B-12 deficiencies, muscular weakness via arthopathies in cats & dogs, heart disease & degeneration, muscle disorder in pigs, general weakness, a stimulant or restorative aid of the metabolic processes, cellular energy depletion, Kyno helps heart & skeletal muscles recompensate.

Administration is intramuscularly, subcutaneous, or intravenous injection. Subcutaneous injection used primarily in dogs and cats. Administer to the anterior neck in food animals. The dosage & frequency administration correlated to selenium content in Kyno.

    Horses & Cattle: 20ml/400kg (0.25ml/kg)
    Foals & Calves: 10ml/100kg (0.1ml/kg)
    Sheep: Up to 5ml (0.2ml/kg)
    Lambs: Up to 2ml (0.2ml/kg)
    Adult Pigs: Up to 10ml/100kg (0.1ml/kg)
    Piglets: Up to 1ml/5kg (0.2ml/kg)
    Dogs: Approximately 2ml-5ml (0.1ml/kg)
    Cats: Approximately 1ml (o.2ml/kg) Used as treatment, recommend one injection every 3 days using 3 to 4 separate occasions. Used for preventative measures, one injection once weekly for a 2-4 week period.

Advised to withhold Kyno from racehorses 24 hours before racing.

No adverse affects have been reported at recommended dose rates.

Licensed under Animals Remedies Act 1967, No. 4234.

Kyno is a Prescription Animal Remedy Class 1, to be used only under veterinary consultation.


Finally, Bryan Haycock MSc., CSCS wrote that - Kynoselen is banned and used in horse and dog racing. He too believes that the active ingredient is Heptaminol. This is an inotropic substance able to influence muscle contractions.

An example of inotropic drugs is caffeine and ephedra. Heptmainol blocks resorption of noradrenalin, which leads to an increase in noradrenalin levels. Hence that reason ECA mixtures are banned in the IOC and other athletic organizations. Flat out they are stimulants but if the U.S. product does not contain heptaminol it will not do anything!

I hope that this helped. As far as the Kyno making him irritable and him not wanting to break his diet…I applaud him for that. The Kyno would not be making him irritable the caloric restriction and increased training around contest time may. He will return to being himself after the competition season is over.

This irritability could be controlled if he had control over his emotions at all times, but speaking from experience this is a difficult task at times. The Kyno definitely has nothing to do with this though. Share this FAQ info with him I am sure he'll appreciate the facts.
