Methylene Blue | 1% USP Grade Solution | 4oz Liquid Drops | Pharmaceutical Grade | Cellular Energy & Mitochondrial Support | Formaldehyde Free | Made in USA (4oz)

This stuff is amazing! I’m 71 years old and have the energy of a 40 year old. My wife is working around the house and not slowing down till about 10PM. I highly recommend this product.

Wasn’t sure what to expect, but methylene blue has been a game-changer for focus and energy. I use a tiny amount diluted in water, and it gives me this calm, clear mental boost—way better than caffeine. Just be careful—it stains everything if you’re not precise.Great quality, shipped fast, and does exactly what I hoped. Definitely recommend if you’re into nootropics or biohacking.

It arrived quickly and not broken so that's good! I just took my first dose about an hour ago. I saw a lot of complaints about the taste but I mixed my dose with 1/4 tsp ascorbic acid and 8oz warm water and there was almost no taste at all :D. So far, I'm very pleased!

I like this..it's better than the other brands ive tried..Will keep using this one. The third party testing sold on it..exceptional quality.

Why does it say, Formaldehyde free? No measure on the tincture so good luck getting your dosage right. Probably has some Formaldehyde in it. No other Methylene Blue has that.

My husband read up on this supplement and insisted we both try it each day. It doesn't taste great, as it shouldn't, so make sure you have a chaser drink there. Also, it definitely stains your teeth and tongue so rinse quickly- be careful not to spill on anything as it can stain. We are happy so far!

Larger bottle and gives about 2 months of doses for cognitive stability high energy and high-quality dropper bottle. I recommend this 5- Star rated.

Great value
