Haven’t used long enough for results

Product is amazing im feeling awesome!

I think it works well and the research is promising on the benefits of this. I don't notice any downsides so far. Price was good for the quantity.

This is a very strong, concentrated liquid and it definitely behaves like it. The solution looks clean and consistent, and the bottle feels well-made and secure. The dropper works fine, but you do have to be careful because this stuff can stain sinks, counters, and basically anything it touches if you’re not paying attention.I also appreciate that the product focuses on purity and testing, and it’s easy to add a few drops to water. That said, I do think this is one of those items where extra caution matters. If you take antidepressants or other mood/brain medications, this is not something to casually combine, and it’s worth treating it as a “do your homework first” type of purchase rather than a simple daily add-on.Overall, it seems high quality and thoughtfully packaged, but I’m giving 4 stars because it’s a potent product that requires careful handling and clearer, stronger interaction guidance right up front.

Life changing supplement. You just gotta get the dosage right

I have no idea what this actually is.Supposed to be doing for me, in like the physiological sense of it's good for me, but it has been turning my urine, a slightly darker shade of blue, which made the whole thing turn green, and it's a lot more fun to pee know.

First time using this product mild bitter taste. After 1 week no more headaches concentration is much better.Excellent price highly recommend.

I feel more focus and more energy with that product.These methylene blue drops are high quality and very easy to use. The dropper makes dosing simple and precise. Great product, well packaged, and exactly as described. I’m very satisfied with my purchase.

Nasty taste!!

It ls good. My husband like it. It will stain stuff so be careful

Arrive on time. Stated to use this product for an elderly relative and started to show benefits.

This bottle of 1% methylene blue arrived on time, as promised by the seller, in a well-packaged amber glass bottle with an excellent quality dropper. It's helping with the healing of a wound my dog ​​has on one of his paws.

Great value!!!

I feel so great. I struggle with breathing sometimes, & knowing that oxygen plays such a major role in energy production i felt like i really needed to breathe easier and use this supplement.feels odd to say a dye makes me feel better than an OTC antihistamine. However, i love knowing the oxygen is going straight to my cells with my trouble breathing.thank you!

High-quality product, very concentrated so a little goes a long way. Arrived well packaged and exactly as described. Very satisfied.

The best methylene blue I’ve found! Pharmaceutical grade, formaldehyde free, 3rd party tested and made in USA! Both me and my husband take it and love it!

The bottle arrived well sealed and clearly labeled. The dropper works smoothly and makes measuring easy. I like that it’s USP grade and comes from an independent lab. Overall, it looks high quality and matches the product description.

What stood out to me about these methylene blue drops is how straightforward the formula is—just a 1% USP‑grade solution in distilled water with no extra fillers or heavy metals listed on the box. The dropper makes it easy to control the dose, and the liquid is strong and very blue, so a little clearly goes a long way. The taste is noticeable but not terrible when mixed into a full glass of water, and the bottle feels sturdy with a cap that seals well so there are no leaks in storage. The packaging also clearly reminds you that it’s not meant to diagnose or treat anything, which is helpful so you go in with realistic expectations and use it responsibly.

I bought the Bluesun methylene blue drops and was very satisfied with the product. The presentation is very good, the bottle is resistant and the dropper allows precise dosing, which is very practical.The liquid has an intense and uniform color, which demonstrates good concentration and quality. It arrived well sealed, with clear labels and a professional appearance. You can see that it is a well-crafted and reliable product.I have used it for general/laboratory purposes and it has perfectly fulfilled expectations. Excellent value for money. I recommend it without a doubt and I would buy it again.

I purchased this after reading about methylene blue and its potential benefits that are being studied, especially around cellular health. I got one for myself and one for my mom who is dealing with health challenges. Happy with the quality and purity. Love that it’s made in USA. So far feels great in my body

I took these drops in small doses mixed with water as directed, and what I’ve noticed is a subtle but real improvement in my daily mental focus and overall energy. Some days I feel sharper and more present, especially during long work sessions. The liquid format makes it super easy to customize the dose to what feels right for me.If you’re curious about supporting mental clarity, sustained energy, or just want a reliable, high-grade methylene blue supplement, this product stands out. Just remember to start with a low dose and adjust gradually, and be mindful to check with a healthcare provider if you’re on medications or have health concerns.

This product appears to work but it caused me to have blue urine. Also it dyes your teeth to the color of blue. My dentist told me to stop using it. It dyed the inside of my coffee cup blue. I had to scrub it with bleach a few times to try and remove the stain. Also, I urinated into one of the Plastic Urine containers to test the blue dye and the container is permanently stained blue like my coffee cup. I had to purchase another coffee cup.

After a few hours of taking it I sensed a difference in focus, energy, a boost in mental acuity, amongst other boosts I'm still discovering and I'm.bately on day two

I use it to have more energy and transport more oxygen to my body, and thus have better health.

I like alot

Excellent product and very good quality. The methylene blue comes well-sealed in an amber glass bottle with a precise dropper and is clearly labeled as USP grade. I was very confident knowing it was third-party tested and included a Certificate of Analysis (COA). The 1% concentration is exactly as described. It arrived quickly and was well-packaged. I definitely recommend it and would buy it again. I recommend the seller 100%.

This product is very effective, highly recommended.

This is high quality, pharmaceutical grade methylene blue drops. It doesn't really have a smell, but it does have a taste, that I dislike. But it hasn't stopped me from taking it, cause it's been extremely effective. It's a dark blue and it will stain anything it comes in contact with. It does come with a safety seal. I think it's an excellent value.

Turned my urine blue. Didn’t notice any change with my physical well being. Small size. Easy to use. No energy change or strength change. Easy to mix. Decent price. Quality is undetermined since I stopped using it due to my urine turning blue and it having a pretty bad taste.

Producto de alta calidad y muy bien presentado
