Quality Methylene Blue option

I've been taking the specific brand of methylene blue for a few months now on and off. I was impressed that Walmart carried this item and I could get it shipped and delivered to my house relatively quickly. I will definitely purchase again in the future. This needs to be diluted in water or another liquid and can cause staining in your mouth and teeth so good they're all rinse afterward is needed, but that is the case with all methylene blue products.

Been taking it for a week now. its too soon to say if its working. But i do feel like its working. I would mix it with something other than water. there is a slight aftertaste when used with water, but not noticeable when mixed with anything else.

I needed to refill my OTC supplement that my usual source was out of. Surprisingly they had it cheaper, so I bought two.
