The product arrived securely sealed, clearly labeled, and the deep blue color indicates high concentration and purity. It dissolves well in distilled water and has been consistent in quality with each use. I’ve been microdosing under careful guidance, and have noticed subtle improvements in focus and mental clarity. As always, anyone considering this for human use should do thorough research and consult a qualified professional, as this is not officially sold as a dietary supplement. Great value for the amount—just handle it with care, as it stains easily and requires precise dosing. Review: Great product. No more to say. - Great product. I purchased smaller bottles with the pipper in, and some longer disposable plastic pippets, so I draw the liquid out of the big bottle into the smaller ones. Tip: do this over your stainless still sink, as this is a dye. Using 5 drops every other day, and the energy levels are unreal. Took down a large tree in my front garden the other day, and fug out the roots. Would nether been able to do that previously. Well not in time I did it in. ## Features - 1% Methylene Blue trihydrate, demineralized water. Pharma grade ingredients: Demineralized water (EP, USP), Methylene blue (USP).

I purchased smaller bottles with the pipper in, and some longer disposable plastic pippets, so I draw the liquid out of the big bottle into the smaller ones. Tip: do this over your stainless still sink, as this is a dye. Using 5 drops every other day, and the energy levels are unreal. Took down a large tree in my front garden the other day, and fug out the roots. Would nether been able to do that previously. Well not in time I did it in. ### ⭐⭐⭐⭐⭐ It works, doesn't stain, taste is fine *by P***W on 3 April 2025* I have chronic fatigue and only Creatine has raised my energy level up a little until now to get me through the day. I've tried this liquid Methylene Blue, followed the very simple instructions exactly (two full pippetes into 200ml of water daily) and I have noticed I'm feeling noticeably less fatigued than I did before. My tongue is blue for about ten minutes, my pee is blue, exactly as expected. I have a glass measuring jug and spoon specifically for this that I use, specifically for this as I'd read Methylene Blue dyes everything it touches. I found I can rinse the glass measuring jug and spoon under the tap and there's no staining. The taste is actually fine for me, it reminds me of eating unsalted almonds. I do prefer savoury foods rather than sweet, I think that makes the bitter taste fine enough for me. The price for the bottle is high but buying much smaller amounts repeatedly is vastly more expensive, so I see this as good value for money for the amount of liquid contained. ## Frequently Bought Together - Methylene Blue 1% Solution 33.8 Fl Oz - 1000 ml Liquid Drops | USP Pharma Grade Ingredients - Third-Party Tested | Glass Bottle | Heiltropfen® - The Ultimate Guide to Methylene Blue: Remarkable Hope for Depression, COVID, AIDS & other Viruses, Alzheimer’s, Autism, Cancer, Heart Disease, ...
