Marketed for is not tested for
A compound can be sold for injury recovery and studied for something else entirely — that is the most common pattern on this site, not the exception. A row saying "trials, but not for injury recovery" means registered studies exist and none of them asked this question. It is not a claim that the compound does nothing.
