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

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.

Helping to boost energy clear brain fog just making my all-around day better and better the more I use it. I 100% recommend doing some research and giving a chance. only side effect is you will be peeing blue and or green variance.

I am pleased with this product. I have been using this brand of Methylene Blue since the beginning of the year. This most recent purchase was my second time buying this brand, and I have no reason to change to any other. I did a lot of research on methylene blue before buying and using it. This brand checked off all of the boxes. The customer service was great, and I received my order earlier than expected.

Seams to be working. Only thing is the taste could be improved a bit. Will buy again.

I don't know about the purity of this product which can't be worse than your average convenient store snack, but I can speak to it's effectiveness. I only take a couple of drops daily and immediately the impact was evident and significant. It has given me clarity along with energy that is more than energy, it's accompanied by a type of motivation. A boost in daily drive. Taste is not pleasant. I highly recommend this.

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.

Potent!! I have to be careful as to how much I take, or I'll be pissing blue for days! Physically I am feeling better, sleeping better, thinking better.

The first time I tried this, I took 3-4 drops and felt myself get pulled into a sweeping state of anxiety.Since I’ve read so many positive reviews on this product and wanted the benefit of the effects, I decided to microdose this product on a daily basis.So now, I put 1-2 drops into a cup of water and drink it in the morning. I feel a slight boost without feeling dizzy and nauseated, which is how I feel if I take too much at once.
