I think that’s an extremely plausible cause given his earlier camp pee was clean, then he tests with this super small amount at the end. And the 2 different unrelated supps both being spiked.
But where he messed up, was trying to pin it on the companies instead of trying to keep the responsibility pinned in his camp.
Stupid petty people get what they deserve, sometimes.
I agree with you that something about the situation just doesn't add up because like you said, the tests from earlier in his camp were clean - so its odd that he would have last minute decided to use something that anyone could have told him would still be in his system and that wouldn't have even had any performance enhancement benefit at the dosages that were in his system.
Also, the dosages in his system were so low that they do suggest a cross contamination level of use - meaning that from the time of the last clean test, even if he had used Ostarine for only a couple weeks at a low dose, higher levels should have been in his system. The levels in his system do suggest a cross contamination dose BUT I don't think its from the supplements that he blamed.
I think there's a chance what you said happened, but I think there's also a couple of other plausible theories.
When these athletes are tested, they are supposed to declare any supplements they are taking. Maybe he didn't declare something else he was taking, whether because he didn't want them to know or bc he simply forgot or didn't take it long, and that was what was cross contaminated. He wouldn't then be able to blame it on that bc he may have finished it or thrown it out, but also blaming it on one he didn't list would be admitting he lied or omitted something on the testing form, which is an offense in itself.
Maybe he took some other performance enhancer or research chemical that wouldn't show up in a test, and it itself was what was cross contaminated with Ostarine. That would line up bc repeated testing of things like that have shown huge cross contamination issues.
If Garcia's team really believed what they were saying, it seems the next step for them would have been to purchase sealed containers and have them sent out for testing. If they did, they haven't announced it. If they didn't, then I think it says something that they didn't.
Irregardless though, to blame it on the wrong products is absolutely terrible.
Both companies accused should have (and probably are having) independent labs find the exact batch numbers for sale at third party retailers and buy them directly (the labs buying them allows for strict chain of custody) and have them sent directly to the labs for testing. If confirmed there is no cross contamination, they should sue him.
----------------
The thing that I'm surprised by the most is that the sanctioning body didn't try to find and buy a sealed container of the batches of accused supplements from third party retailers and have them sent directly to the lab for testing.
I think that that is a needed step in situations like this - if an athlete is going to make an accusation like this in order to get a reduced punishment from an athletic committee or sanctioning body, I think the open container that the athlete has should be tested but I think a sealed container should be purchased by the sanctioning body of the same batch and sent out for independent testing direct from third party retailer to the lab. That keeps chain of custody intact and gives a definitive answer and I think if the athlete is found to be lying, they should be punished for that in addition to the punishment for failing the drug test to begin with.
