Methylene Blue, 1% USP (Pharmaceutical) Grade, 50 mL (1.69 fl oz); 3rd Party Tested

Very nice neurotrophic. I got this to replace a bottle that had broken. Side note, Bar keepers friend does fantastic in removing it from most hard surfaces. In my case it was tile and grout. Make a paste and rub, may have to do it more than once. Finish with clear water, damp rag. I've noticed that it does help me with focus and it took about a week and I noticed a definite settling out with my moods. Good price point, made in USA, 3rd party tested, overall good stuff. Easy to use, figure out the dose for you and then start on the low end and work up to that dose if needed. Do recommend.

It's an excellent product, and it starts working on day one.

It’s my first bottle ever, and it definitely gives me more energy. I am narrow, fatigued, and this helps a lot.

I am stepping slowly in to this as it something new to me. I am currently using 8 drops in 6 oz of water. At this dose I don't feel anything, but effects may be taking place. I'm moving to 12 drops.

UPDATE..... I now take 5 drops 2 times a day befor noon. but plan on breaks from taking it every 10 days. i take no other drugs so get no headaches or nausia. i also found it to help with mouth issues, brain fog and urinary tract issues. at 70 years old i feel better than i did in high school!there seems to be a lot of great info on youtube with Dr. info and dosage information. dont take to much to start... go slow with getting used to dosing. i am getting a lot of healing in things i thought i would just have to live with. started out with 1 drop a day and moved to 3 drops each morning in about 4 oz of cold water each morning seems to do what is needed for me. wish i found this years ago... but this and my red light therapy is working wonderful things for my brain and body. THANK YOU!

Im really not seeing any difference really

Works fast! I did ten drops in a 6oz glass of water. This is the best price for the amount of product you will get. It tastes bitter but it’s not too bad. I chugged it with no problems. There’s no dropper but you won’t need it since the bottle design is made so that you can invert it and dispense it drop by drop.

This is a powerful drug. This should only be used with the supervision of a doctor who is familiar with it or is willing to do some research. It is a very old and time-tested drug but it is very strong. Only extremely small, carefully measured amounts should be used. When I say small amounts, I mean drops. To learn more Google "Methylene Blue Serotonin Syndrome." You literally could kill yourself taking this carelessly. It is amazing and bizarre taht it is sold over the counter. My doctor was flabergasted that this is sold without a prescription.
