Methylene Blue, 1% USP (Pharmaceutical) Grade: 50 mL Bottle with 8 oz Refill 2-Pack Glass Kit; 3rd Party Tested

I got my smell back! I lost my sense of smell from COVID in 2021 and now it's back. Have to be careful about my farts now. Geez, I stink!Use with Red light therapy. I'm doing it on my face for skin cancer to see if it works.

Works great! Works as it should. But then again: be extra careful transferring it from the large bottle to a smaller one. Even with the use of a funnel, it's very BLUE!

Carefully packaged and shipped, this is appreciated. It is pharmaceutical grade. If you are using it for health benefits you need to read a book on it. I like the book by Mark Sloan. He's got a chart in it for dosage.

The only issue that I have is that the eye dropper is about 1/8" or more too short to reach the bottom of the bottle. Explain how to get what is in the bottom of the bottle out when you can't immediately refill.

I like what it does for my brain and body.

I usually buy the small dropper size bottle but opted forA larger one once opened the box the lid was not secure? Leaked out MB onto my counter

It helps me with sleep, mental, antioxidant.

I have tried to order this product twice. Zero response! The order window continuously displays 'ORDER RECIEVED' Yet there is NO movement showing this order is being filled or sent... NOTHING!I canceled the order and went with another seller. Shame because this is a very good product!
