THIS ENDS THE HAIR FOLLICLE debate - IT IS UNRELIABLE!

[Cheek busting]

The hair test

There has been a push in some quarters to use the “hair test” in order to convict or clear Canelo. To hear it told, this hair test is the answer to every question. In reality, hair testing for clenbuterol isn’t used for a reason; it’s incredibly unreliable.

The amount of clenbuterol that shows up in hair varies massively depending on factors like hair color. One study gave a group of people the same amount of clenbuterol. One participant, a 27-year-old female, showed 23 ng/g of clenbuterol in her hair afterwards. Another participant, also a 27-year-old female, showed 161 ng/g of clenbuterol in her hair. They both took the exact same amount, but one had seven times as much in her sample. The suggested reason for this discrepancy? The women had different hair color. This hair color discrepancy was supported by the other data in the study.

That might sound ridiculous, but other studies have found the same thing.

Another study, with more participants, found that even among subjects with similar hair color, the variation is still large. Despite every subject having hair listed as “brown” or “dark brown”, this study also found significant variation:

The lowest detected amount of clenbuterol in the first segment of hair was 0.43 pg/ng, the largest amount was 4.76 pg/ng. Both of these subjects had hair classed as “brown,” and both took the same amount of clenbuterol in the same way. That’s a difference of an entire order of magnitude. A similar issue was found in the second segments, which ranged from a detected amount of 0.00 pg/ng to 0.86 pg/ng.

Tests that have results varying by so much even under a controlled conditions are not reliable tests. The idea that they would somehow give us the information we need to determine if Canelo accidentally or deliberately ingested clenbuterol is ridiculous.

Drug expert Victor Conte who knows about this shyt more then anybody directly dis*****g these claims

Hair is a scientifically valid sample type 4 clenbuterol testing in the Canelo case. Yes there are variations w/ hair color. However they measure at picogram concentrations. A picogram is equal to one trillionth of a gram. This is ultra trace analysis by a WADA accredited lab.

Attacking the scientific credibility of hair testing for clenbuterol because of color variations is simply an uninformed argument. Many drug tests have all kinds of variations. Urine samples can be diluted or concentrated. Asians have much lower T/E ratios compared to blacks etc.

CANELO: The WADA accedited lab knows about color variations & that head & pubic hair have different growth rates. It is significant that they did not detect clenbuterol in the hair of Canelo. This is IMPORTANT EVIDENCE in favor of Canelo's defense.

There's a reason they kept the test secret. There was probably a 50/50 chance Canelo would have failed. If he failed we wouldnt have heard a word. Now that he passed its out there. With Canelos hair color the test is pretty much unreliable for Clenbuterol only. They didnt even test for any other substances or at least dont put out that information to the public. This is all extremely shady. Pure damage control.

In those studies, they all had varying results. Everyone who used popped but at different levels. Canelo had no levels.

Are people really using a study to supplement hearsay? You can’t use a study to prove something wrong when what you’re proving has ZERO to do with the study. If he had some low levels I’d see the nexus but he has zero. Nothing to variate.

And now it’s some kind of witch hunt? He popped for clen and is trying to prove he didn’t use clen. He passes his test but it’s a sham because they didn’t tesf him for other unrelated things? What kind of logic is this?

If you were accused of a singular crime..stole a car for example and literally that was it. Why would they try you for an unrelated murder? Do you realize what you’re saying? No offense man but lets keep it objective here.

It’s looking like Canelo may be telling the truth and judging from that Victor Conte post, it’s a legitimate form of testing. Again, from what it seems, there’s a variation for levels that come back but there seems to ALWAYS be levels that come back. Nowhere have I seen that it is so unreliable that some people come back negative. It’s like saying a woman is only a little bit pregnant.

If he’s innocent then great for him. If he isn’t, that’s too bad.

If I’m Canelo though, I get as much proof as I can of my (presumed) innocence and go on a mass lawsuit spree on everyone who attacked his character/defamed a la Pac-Floyd.

Anyway...I mean... zero traces kind of speaks for itself and completely refutes the variation portion it would seem. Unless there’s variation between zero levels and I misread the study, it’s still reaching at best to think he’d be one of the anomalies to test for zero.

Doesn't that raise the question of why the previous tests showed Clenbuterol though. Surely the HFT should have shown up the trace levels found by previous tests, and since it didn't then perhaps we need to be asking why.

[Elroy The Great]

any test gives him a failing result is the only test worth accepting

those who have it dead set against nelo will NEVER be convinced otherwise.

and thats sad

thats more of an indication of what kind a fight fan a person is.

no offence to CB but its time to relent. nelo isnt the bad guy hes made out to be.

he ate tainted meat.

everyone who isnt biased is acknowledging this

emotional types continue on with this hatefest

let it go

I hope & pray Vanes outboxes GGG so this whole debacle will die.

I'm not sure how this is still a debate. There is only one actual fact in this whole ordeal. Canelo had Clenbuterol in his system in Feb. That's a fact that is not disputed by anyone. Whether it was from meat contamination or PED usage is irrelevant.

If hair follicle result was NEGATIVE, it shows that the test itself was useless. You can point to anything you want, either the test is not conclusive, the threshold set was too high, the time period elapsed was too long, they faked the test, w/e.

We KNOW he had Clen in his system. If the hair test says he did not, it's useless. Simple as that.

Bing. ****. Boom.

And I simply believe the much more likely reason why he had CLen in his system, was to get a competitive advantage.
