Methylene Blue Pharmaceutical Grade, USP Grade, Third-Party Tested Brain Health Dietary Supplement for Humans, No Formaldehyde, Made in USA (0.5% 50ml Bottle)

Pretty good product. Noticed a difference on day two. Staying around 5 drops daily. I do three drops in a medium glass of water then hour later do two more. It does taste nasty which is why I split my dose. Be careful it will permanently stain fabric and some surfaces. Noticed a clearer head and less fatigue.

I am a big nootropics guy and have ran through most of what's out there, 9-mbc, noopept, racetams you name it. After trying this I've gotta say, the mood change, motivation, focus, concentration are top notch!! Buy this right now and experiment with dosage but for the love of all that's holy DO NOT get it on you or clothes because it's very hard to get off. This stuff is legit and I was always curious about it but always passed it by assuming it wasn't all that. Believe me I was dead wrong and will be ordering more because I love it from day one. Tried a small amount early and was like "ok...ok this seems good" then a larger dose hours later and started raving to my beautiful fiancé that she has got to try it to remove brain fog. Top notch, can't say enough good things about methylene blue 😄😄 impressed and surprised!!

This stuff is UNBELIEVABLE!!look it up and do the research! This is one of the most recommended brands and it's SO POWERFUL..JUST tryUPDATE, after 30 days or more use i notice my skin tighten up! Not just a little! But DRAMATIC took ten years off my age look!!Crows feet and such GONE!!This is hands down the most powerful supplement I've ever used!!I've never had something have so many benefits but no backfire! The ONLY thing I've found is if I take too much I get a slight headache, so I don't take to much (5mg, once or twice/daily)I tried another brand as well and came running back here!

It's only been one day, but I already noticed an improvement. I took it last night before bed (sucked through a straw at the back of my tongue to minimize blue mouth and teeth), and I woke up with MUCH LESS morning grogginess. I felt clear-thinking and had no problems staying focused at work, despite having only 5 hours of sleep. I didn't expect any results this soon, so today was a very pleasant surprise (as was the green pee in the toilet).

Works well

Restored my strength. Gave me my life back.Have been taking 14 drops in water everyday for about a year already.

So far so good, I feel this is a quality product and love the lack of brain fog

No, this seems weird but as soon as I started taking it within the first couple days, my brain fog was gone
