## Questions & Answers

**Q: I bought this, but cannot unscrew the dropper.  Any suggestions?**
A: I hold the dropper and turn the bottle clockwise while it sits on my counter

**Q: Is this actually usp grade as there is no usp labeling on the bottle?**
A: There is a statement in EXCEEDINGLY small print....kind of a sales pitch... saying enjoy your USP grade Methylene Blue, but I do not see any official symbol representing that statement.  On the contrary, there IS a prominent statement saying, "For Research and Development purposes ONLY."  It scared me enough to not use it.   I'm trying to look into it too.

**Q: My bottle came without a dropper, is that the new normal?**
A: Too many people like me take more than the dropper will hold and the blue stain makes it hard to see markings on the dropper

**Q: Why is the product description different then the actual bottle label i received, it does not say usp on the bottle but it does on the product page?**
A: Jut used to have the labeling. I still get a lab essay on purity if I ask.
