By Steve Haigh – As we all know Canelo Alvarez has tested positive for Clenbuterol and GBP have issued a statement (below)
Statement From Golden Boy Promotions: As part of the voluntary testing program that Canelo Alvarez insisted on ahead of his May 5 fight, one of his results came back positive for trace levels of Clenbuterol, consistent with meat contamination that has impacted dozens of athletes in Mexico over the last years.
As Daniel Eichner, Director of SMRTL, the WADA-accredited lab that conducted the tests stated in his letter today, “These values are all within the range of what is expected from meat contamination.”
Upon receiving this information, Golden Boy immediately notified the Nevada State Athletic Commission and Gennady Golovkin’s promoter Tom Loeffler.
As has been planned, Canelo will immediately move his training camp from Mexico to the United States and will submit to any number and variety of additional tests that VADA deems necessary ahead of and after May 5.
Added Canelo: “I am an athlete who respects the sport and this surprises me and bothers me because it had never happened to me. I will submit to all the tests that require me to clarify this embarrassing situation and I trust that at the end the truth will prevail.”
Canelo has tested clean dozens of times over the course of his previous 12 fights.
I personally don’t buy it.
Clenbuterol is a bronchial dilator which helps asthmatic.It also has thermogenic properties that aid metabolism and the burning of fat whilst preserving muscle tissue.
A user will also benefit from prolonged endurance or stamina which is something we’ve seen lacking from Canelo, but more importantly, it will also prove beneficial as a masking agent for more harder compounds such as Human Growth Hormone or AAS (anabolic and androgenic steroids)
Clenbuterol has a half-life of 36 hours and a detection time of 4-6 days.
Therefore consumption of contaminated beef being the cause is very unlikely as the time it takes from slaughterhouse to the plate would more than likely exceed the time frames.
Here is some more information on the substance in sport and ill leave you to draw your own conclusions.
Clenbuterol is excreted from the body in the urine and can thus be detected by analysis using such technology as mass spectrometry.
Currently the most sensitive equipment is capable of detecting Clenbuterol concentrations as low as 5-10pg/ml in the urine, but WADA only requires that an accredited laboratory be able to detect a level as low as 2ng/ml (a picogram (pg) is one-trillionth of a gram; whilst a nanogram (ng) is one billionth of a gram).
A typical dose used by an athlete might be in the range of 50-100µg(microgram, one millionth of a gram) or higher, and under these conditions, Clenbuterol may be detected in the urine for a week or longer after it was last consumed.
Since Clenbuterol is used on livestock to increase the proportion of lean meat, it can potentially be consumed by humans without their knowledge. In Europe, meat sold for human consumption is required to have a level of Clenbuterol less than 100ng/kg but elsewhere – particularly in China, Mexico and the Latin American region – standards may not be enforced.
Thus athletes who have tested positive for this substance in recent times have argued that their ingestion of this substance was accidental rather than the result of intentional doping.
Some scientists believe that this uncertainty might be alleviated by instituting a threshold for Clenbuterol — a level below which a positive would not be considered doping — but WADA has announced that it has no plans to change the status of the drug.
The current situation therefore remains: the outcome of each case is determined by whether or not an athlete can successfully argue that the evidence supports the conclusion that ingestion resulted from contaminated food.
Such evidence might include the location in which the meat was obtained or a hair test since Clenbuterol, like many other substances, accumulates in very small amounts in hair follicles. If an athlete has taken the substance over a period of time in the past, his/her hair test might return a positive for a period of six months or longer. Conversely, if the Clenbuterol resulted from a single incident, in which the subject had eaten meat for example, a hair test would almost certainly be negative.
