This stuff is AMAZING! I put 3 drops in a water bottle everyday and the focus it gives you and mental clarity is unlike any other. It's a clean feeling and doesn't make you feel like you took anything. The natural energy it gives you is wonderful. I'm a mom of 3 boys and this stuff makes my days more productive. There is no taste which is lovely. The price is wonderful because this bottle will last you all year long. 10/10 recommend

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.

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.

This was my first purchase of methylene blue after I learned about it through social media, online, and a friend. This product does work as intended. I feel a steady and "ready" body and mental energy. I am a healthy sweater, and after taking this product, I am sweating with any increase in temperature or body exertion. Unlike coffee, I do not feel the adrenaline rush or bump. I also think it is hard to tell how much you're getting in the dropper; you'll have to take the company's word for it. I am still researching if I should move to the troche(dry, measured block) since there is some skepticism on the accuracy of dosing. I'm taking it slow and up to 4-5mg per serving once or twice daily. I may up it to see if there are any additional benefits. It will likely turn into a supplement that I'll use to optimize health and not for a long-term routine.

I think the supplement is effective for the people that can take it, however, it did not work for either of us. He got sick with the runs and cramps, and for me, it just had no effect at all.

I received this methylene blue quickly and in perfect condition. It comes in a sturdy glass bottle with a dropper, which makes it easy to measure and use. The 1% solution is clear, deep blue, and has no strange smell. I appreciate that it is made in the USA, tested by a third party, and contains no heavy metals. I feel confident using it and will definitely order again.

Does it work? I'm not really sure. I think I feel better. I'm on day 10 of using this stuff. There is no dosage on the bottle so I had to go to the googles to see what the proper dosage is. Turns out all I found was someone saying 3-5 drops. Make my water taste like fabric dye but it's not unbearable. My pee is green and I'm not really sure about anything else. Make sure you don't take it if you're on SSRIs or MAOI inhibitors. Apparently that's bad and can cause a Serotonin issue that can kill you so that's important.
