It makes a difference. I put 4 scoops citric acid with 20 drop water mixture, wait 5 min color goes to light blue. extra vitamin c is good too.

Gives me instant energy when I first started taking 20 drops with full glass of water in the mornings, Great detox also

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.

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!

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.

It works!!! I feel great!!! It tastes like death on a cracker!!!

AMAZINNNNNG PRODUCT!!!! GOT ME RIGHT!
