Great product
Been taking this for 6 years. Compass is a brand you can trust.

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.

Directions?
Am I missing something? Where are the directions for this product? How much do I take? It says drop? Like one tiny drop or a full vial of the dropper that comes with it? How ridiculous to not have directions on the bottle.

Still working
Helps a lot with memory & brain fog. It also has cured my constipation issues I had all my life. Been using it since April 2025. Initially I had slot of energy but after using it for some time I no longer get the enerGuy boost.

Not as good as others out there
I bought two bottles. For my body size, I needed 7 mL of the 0.5% solution. Shortly after taking it, my urine turned deep blue. I used up both bottles. Then, I found a higher grade 2% solution of Methylene Blue by Heiltropfen and started taking it. To equal the same dose took only 2 mL. After taking it for several days, I noticed that my urine was not changing colors very much, which means this new 2% solution is better refined and pure, and is being better absorbed by my body.

Bad taste and zero results
The product has absolutely zero effect on me and the taste is disgustingly bad.
