My brother keeps the injectable type around for his dogs, actually uses it as a pour on. I've used some by pouring it on my arms and rubbing it in. Talked to a vet the other day and he said he knows several guys who rub it into their hands like hand cream. None of them have even had a cold this winter.
Edit to add: Had a bit of an argument with my dr last summer when I went in for an A1C test. I was complaining about all the mask requirements, spacing, stay in your car till called, ect. I told him I'd seen studies showing that masks do more harm than good with all the different types of materials and such that people were using. He finally shrugged his shoulders and admitted that they knew it was BS, but if they didn't do it too many people who believed the hype wouldn't come in for treatment when they really were sick.
