Wild to see how popular methylene blue is getting, I appreciate that there are many USP-grade products these days.

I purchased my first bottle in 2014 at a fish shop as it was commercialized mostly as a fish tank disinfectant.😅

As well as education around it, my first dose was way too high and gave me a serotonin reaction I thought I would die.

Keep in mind MB is a very strong MAO inhibitor so never overdo it - and not a single drop if taking antidepressants! (That you should throw away anyway)
