Canelo was already proven innocent and the clen trace was from tainted meat. Everyone here who claims he used Clenbuterol for the 2nd Golovkin fight are fúcking idiots
Canelo submitted to hair follicle testing at the request of the Nevada State Athletic Commission and the test came back negative for the banned performance-enhancing drug clenbuterol, lending some credence to Alvarez's insistence that his two positive drug tests for the substance in February, which caused his rematch with unified middleweight world champion Gennady Golovkin to be canceled, were caused by eating contaminated beef.
The Nevada commission collected hair samples from Alvarez on March 29 and they were tested at the Sports Medicine Research & Testing Laboratory, a WADA-accredited lab in Salt Lake City, Utah, Bob Bennett, the commission executive director, told ESPN.
The results document, which was provided to ESPN, was returned on April 20 with a single note in the section reserved for analysis details: "Hair sample tested for clenbuterol. Clenbuterol was not detected."
The negative hair follicle test is notable because while clenbuterol is detectable in urine for less than a week after it is ingested, the drug can be detected in hair for several months.
That would appear to lend credibility to Alvarez's assertion that he was positive for trace amounts of clenbuterol in random urine tests conducted by the Voluntary Anti-Doping Association in his hometown of Guadalajara, Mexico, on Feb. 17 and Feb. 20 because he consumed a small amount that was present in the meat he ate as opposed to taking larger doses of the substance as part of a doping program that would be more likely to remain in his hair follicles for months after he had stopped taking it.
According to Dopeology.org, which extensively covers doping in professional cycling, "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."
"From the beginning, Canelo has insisted that he accidentally ingested clenbuterol from eating tainted meat," Eric Gomez, president of Golden Boy Promotions, Alvarez's promoter, told ESPN. "The fact this NSAC-required hair follicle test came back entirely negative for any traces of clenbuterol should lay to rest any su****ion that he was intentionally taking a banned substance. Canelo is looking forward to getting back into training and returning to the ring in September. He thanks all of his fans for sticking by him and believes this test proves once and for all that he is a clean fighter."
Contaminated meat in Mexico is a long-standing issue for athletes in Mexico, where farmers often include the substance in cattle feed because it helps reduce fat and increase lean muscle mass.
"They found traces of clenbuterol in his system and if he was using it (to dope) there would probably still be enough in his system that it would show up in his hair," Golden Boy Promotions CEO Oscar De La Hoya told ESPN. "We did the hair test to prove this was accidental. Canelo is telling the truth about the meat contamination and he went far and beyond what he had to do by agreeing to have this hair test done so he can keep on proving that he is an innocent fighter.
"Meat contamination is a problem in Mexico. It happened with the national soccer team and it has happened with several athletes in Mexico. I believe what Canelo wants to do now is keep proving until his career is over, 10 or 15 years from now, that he is a clean fighter and an innocent fighter and that he did not do this purposely whatsoever."

Clenbuterol can be detected in hair with more accuracy than urine. here is the Scientific study:
Quote:
Several bodybuilders, all winners of international competitions, were arrested for trafficking of a number of doping agents including anabolic steroids, ephedrine, beta-adrenergics, human chorionic gonadotropin, antidepressants, and diuretics.
In accordance with the recent French law against doping, the judge asked to test seven bodybuilders to identify doping practices. Hair and urine specimens were collected for analysis. After decontamination, a 100 mg hair strand was pulverized in a ball mill, hydrolyzed, extracted, and derivatized to be tested by GC/MS for anabolic steroids, beta-adrenergic compounds, ephedrine, and other doping agents. Urine was analyzed for anabolic steroids and metabolites, beta-adrenergic compounds, ephedrine, and human chorionic gonadotropin, in addition to a broad spectrum screening with GC/MS.
The following compounds were detected in urine: ephedrine (29 and 36 ng/ml, n = 2), clenbuterol (0.2 to 0.3 ng/ml, n = 3), norandrosterone (4.7 to 100.7 ng/ml, n = 7), norethiocholanolone (0.9 to 161.8 ng/ml, n = 6), stanozolol (1 to 25.8 ng/ml, n = 4), methenolone (2.5 to 29.7 ng/ml, n = 4), testosterone (3 to 59.6 ng/ml, n = 7), epitestosterone (1 to 20.4 ng/ml, n = 7) and ratio testosterone/epitestosterone n = 6 for four subjects (18.5 to 59.6).
The following drugs were detected in hair: ephedrine (0.67 and 10.70 ng/mg, n = 2), salbutamol (15 to 31 pg/mg, n = 3), clenbuterol (15 to 122 pg/mg, n = 6), nandrolone (1 to 7.5 pg/mg, n = 3), stanozolol (2 to 84 pg/mg, n = 4), methenolone (17 and 34 ng/ml, n = 2), testosterone enanthate (0.6 to 18.8 ng/mg, n = 5), and testosterone cypionate (3.3 to 4.8 ng/mg, n = 2). These results document the doping practice and demonstrate repetitive exposure to anabolic compounds and confirm the value of hair analysis as a complement to urinalysis in the control of doping practice.

In urine tests, 3 of 7 bodybuilders tested positive for Clenbuterol. In hair testing, 6 o 7 tested positive for Clenbuterol.
