Good concentration level as I'm only 3 days in promising start .seems like a good product in the making .will continue and see what happens .it's a product you have to continue to get the benefits.

Bright color and tasteless, so easy to drink

Prompt delivery, well packaged. It’s the first time I’ve ordered it. I’m using it for putting in the bath and for drinking (diluted in water of course.) A bland taste, which is good, but as with all methylene blue, it stains the teeth and tongue etc for a while. I am taking 5 drops daily and have done for about 2 weeks - I can’t say I’m feeling any difference so far, but that’s OK.

Only just received it and for all the packaging it still leaked and stained my hands and had to handle with care and paper towels. Just taken two drops in water, not sure if you supposed to mix it because it sort of lingered in strands in the water, but as I drank it began to disperse more. Will write again regards effects in a week or two.

Well packaged and as expected

There was a leak in the box when I received it. The bottle was not sealed.My first impression was blue dye everywhere.

Excellent product, thank you! one has to be super careful with it, as it stains very quickly and easily, but there is a knack to using it. It has definitely made a difference to me

I haven’t tried it yet, but arrived fast, sealed and well packaged.
