Methylene Blue Solution USP Grade 1% No Formaldehyde 3rd Party Tested

Easy to administer worked as expected Great stuff, as always, due diligence in researching if you need it or not. Hint; place droplet near back of tongue, swallow with water immediately to reduce blue coloration on lips and tongue. Remove dentures before to save cleanup time. Brush as usual to remove any blue from teeth.

No disappointment here! Good product for the price and very effective!!

it's a great addition to healthy journey

If there is no heat going down your throat and your urine isn't blue, you got fake Chinese sourced M-Blue.

Had other brands of Methylene Blue in the past. This seems to be descent quality. But, the bottle is super tiny for the price.

it's not for human consumption it's to clean fish bowls, so if that's what you need it for than it's a great product. but I wanted it for health reasons and it was not the right product for that.

Tastes like it doesnt want younto eat it. Tried for two days but couldnt get past that taste. Would need to work like the pills from "Limitless" to be worth it.

Uno de los aplicadores llegó partido por lo cual me es inservible One of the applicators arrived party so it is useless to me

This made me jittery and sick. I had to stop using it. Apparently, many sellers say their methlylane blue is pharmacutical food grade and safe, when its actually the raw industrial clothing dye full of bad ingredients. The taste was bad too.

Yucky. Stains your mouth.
