I was very impressed with the quality of this methylene blue powder. The 3.53 fl oz bottle is perfect for long-term and safe use. I love that it's third-party tested, providing confidence in its purity and effectiveness. It also meets USP grade standards, which is essential for those of us looking for safe, high-quality supplements.This product is ideal as a dietary supplement for brain health. It dissolves very well, leaves no residue, and the concentration is excellent. I definitely recommend this product to anyone looking for quality, reliability, and results. A purchase worth every penny!

As someone who uses methylene blue for various purposes, I was really pleased with the quality of this HXOGYUB powder. It comes in a small 3g bottle, but a little goes a long way, especially when diluted properly. The powder is fine, vibrant, and dissolves easily without leaving residue, which tells me it’s high purity. I personally use it for scientific experiments and occasional water treatment, and the results have been consistent every time. The packaging is secure and the bottle is clearly labeled with instructions, which I really appreciate. It’s also nice that it has a tight seal, no leaks or mess. If you need methylene blue for research, aquarium care, or other controlled uses, this product is definitely reliable and delivers what it promises.

This 5% Methylene Blue is top-notch! The pharmaceutical grade quality gives me confidence in its purity and effectiveness. It comes in a dark glass bottle with a dropper, which makes dosing easy and precise. I appreciate that it's non-GMO, free from additives, and lab-tested. Perfect for anyone seeking a reliable and clean formulation for their wellness routine.

It comes well sealed, in a practical and easy-to-handle presentation. The colour is very intense and dissolves quickly in water, which demonstrates its purity.

I truly appreciate that they tried to make this easy, but it is not easy. It is messy, it is dangerous, it is not worth the price, even though the price per gram is very reasonable (for Amazon). I got one bottle with a broken glass dropper in it so that one went right to the trash. Every bottle I have used so far leaks out of the bulb so my fingers turn blue no matter how well I rinse the bulb off after each use. The act of shaking the contents then squeezing the bulb causes leakage onto the bulb which I don't notice right away because my MB is reduces to leukomethylene blue and is close to clear, until it soaks into the skin, then it is deep blue. The stains take several hours to fade away. Also, having the powder in the bottle with the dropper is a problem. The powder sticks to the dropper so when you remove the dropper and set it down, some of that powder is lost. somehow one of my bottles came with MB powder between the cap and the bottle threads so when I opened it, the powder fell out. There was no way to know how much remained inside after this incident. the measuring cup indicates that the measurements are approximate, which is just plain ludicrous. I could go on, but I don't remember every little issue. It's a bad setup and completely unnecessary. They should just sell little packs of MB, one or two GOOD bottles that don't break or leak (for something as staining as MB, plastic would make more sense) and one beaker. No funnel is needed. The package could be 1/3 the size and the contents more user-friendly.

The media could not be loaded. I am extremely pleased with this Methylene Blue Powder Kit! It includes (8) 1-gram vials, a measuring cup, and a funnel. This makes it incredibly easy to create a 1% methylene blue solution—just add distilled water, and you’re ready to go. The instructions are straightforward, and the process is simple even for a first-time user. As a dietary supplement, I’ve noticed significant improvements in my mental clarity and sharpness. It’s clear this formulation is carefully designed to support mitochondrial energy production and promote blood and oxygen flow to the brain. I’ve felt more focused and energized since starting this supplement. Another thing I really like is its purity—being free of formaldehyde and compliant with USP-grade standards ensures safety and quality, which is critical for a product like this. Highly recommended for its quality, convenience, and effectiveness!

This is a promising supplement! I am excited to be trying it. Mixed with 100ml warmed distilled water, I keep it in the fridge, and my personal regimen includes only a small dose (1 drop) of the MB. So far, so good, as I have only been taking this supplement a short while. No issues with smell or taste. I think my sleep has improved too. So far, so good, and I recommend it!
