Review: Great quality - It helped me
Review: Great product. - This is an amazing product. Great value for the money, and effective as well as easy to use... Just add a few drops to water or juice... great for sleep and minor pain relief. Just be sure to keep the doses small and don't take this if you are on any form of SSRI's. Most people should consult a doctor before taking this, or take it while under the care of a physician familiar with this product. It will make you pee blue, and it will permanently stain anything it touches, so handle with Care.

## 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.
