Methylene Blue Pharmaceutical Grade 3.75 fl oz, USA Made Glass Bottle and Dropper Pure 1% Aqueous Solution 110 mL, Zero Heavy Metals 3rd Party Tested

This has been really great so far. It's the first time I've tried it, but I feel it's great quality and I feel it has increased my energy and focus. It's a pretty decent quantity and value comparitively, and the data sheet shows it's been tested. It doesn't taste good, and I'd recommend having water or a flavored drink to wash it down. I generally take a few drops and it seems to increase my energy in an hour. I haven't had any stomach upset or negative symptoms from it and I'm a super sensitive person so I definitely recommend so far so good.

Great health aid for mental clarity, smooth & elevated energy lift & overall wellbeing. Replaced a.m. coffee. Like that it's USP grade & richer than less expensive brands. Beware of stained fingers & teeth I mix in juices/smoothies & drink thru a straw to keep off my teeth. Love it's benefits!!!

I am recovering from prostate cancer (Numbers look good and I am in remission so that's great) and I have been on adderall for fatigue and mental brain fog due to a lack of testosterone from my hormone therapy.This was recommended to me by a doctor and I bought it to try instead of the adderall and it works great. The adderall had side effects including trouble sleeping, but the Methylene Blue gives me a noticeable mental boost, energy and focus (better than adderall) without the sleep troubles.According to the experts I am supposed to take 20 drops per day for my body weight, so I started with ten ten in the morning and planned on taking another ten in the afternoon, but I don't need the afternoon ten drops, so I have just stuck with ten drops once a day. A full dropper is 15 drops and sometimes I'll just take the full dropper so that I don't have to count drops but I don't really need the fifteen drops because ten works fine.I add them to about 5 or 6 ounces of water and hoark it down. It tastes very slightly metallic but not bad. I was afraid it'd be awful tasting, but it's not so bad.I am not a doctor. Do your own research.

This pharmaceutical-grade methylene blue is exactly what I was looking for—clean, pure, and easy to use in small amounts. The quality feels reliable, and it arrived well-packaged. Definitely recommend if you're using it for research or other careful applications.

I am trying to vet this product more since the supplied lab results are not including all toxic materials that show up in the manufacturing process of Methylene Blue. There are different levels of purity and you need to be taking the purest form and long term use with low purity can cause health issues. I am unable to find information on the actual company besides an LLC agent address that has been used for scams.. very concerned.. I would love some more thorough testing results supplied and company contact information would be great.. Everyone needs to stay vigilant with safety of products being sold on Amazon.

It seems to work as described but there is no markings on the dropper so you aren't sure how much you are using but other than that its a decent product.

First off, I am running a minimum of a 5k per day the entire year of 2025; zero rest days. Starting in March, I began sprinkling in longer runs, from 10k to 10 mile to half marathon. Needless to say, I've been more tired lately. I heard about MB on a Joe Rogan podcast and decided to give it a shot; 10mg (20 drops) in the morning, 5mg (10 drops) at night. I calculated the half life of these doses and you'll neve get over 12mg in your bloodstream using these doses.....so no real risk of building up to toxicity levels. See the attached excel screenshotIt's a very low dose for a 220 pound man, but it has (seemingly) been very effective for me. Figure 15mg for a 100kg man = 0.15mg/kg of weight. I ran 8 miles + walked 6.5 on Monday. I ran a sub-30 5k, walked a 5k, and rode my bike 20 miles on Tuesday. I ran 10 miles and walked a 5k on Wednesday....and before I started, I felt heavy and exhausted in my legs. Two miles in and I felt great. This morning, I ran a 5k. I don't run fast (~10min/mile), but I do suffer and run far and long whenever possible. And this week, I have felt good, happy, and aware on my runs. I'm not a natural runner and i'm not a good runner, but the MB has seemingly made a big difference for me. First thought was that it was all placebo. But my performance (moreso in stamina and feeling energetic) increased despite today being day 86 straight of running a minimum of 5k per day.On the downside, I noticed high levels of copper @ 27ppm, but when comparing 10 drops @ 27ppm of copper and a gallon of water @ 1.3ppm......i've decided to accept it unless someone can give some insight and push me toward another reasonably priced brand.So in summary, I truly believe this stuff is making a big difference for me. Maybe i'll have a change of heart, but i'll give it a go for a while and measure the results.

Well I heard the Buzz about this stuff on podcast and advertising ads there's a ton of brands out there I'm sure some are better than others as well . I just got it today 1 day to my door tried it around 3 pm 5 drops in about 16 Oz of water 💧 noticed results about 30 min later energy boosted and better Mood 😀 more positive Happier more peaceful it is not my imagination.
