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

You may feel the detox effects quicker than you were expecting. But it works! Clarity is UNREAL! If you've ever seen limitless, thats what this is.

Works just fine!

Helps a lot with memory & brain fog. It also has cured my constipation issues I had all my life. Been using it since April 2025. Initially I had slot of energy but after using it for some time I no longer get the enerGuy boost.

Great quality

This is an amazing product. Great value for the money, and effective as well as easy to use... Just add a few drops to water or juice... great for sleep and minor pain relief. Just be sure to keep the doses small and don't take this if you are on any form of SSRI's. Most people should consult a doctor before taking this, or take it while under the care of a physician familiar with this product. It will make you pee blue, and it will permanently stain anything it touches, so handle with Care.

I'm not one to write reviews, but I do happen to like and wear pretty expensive and comfortable clothes. This review is not about the quality of the product, (I didn't get that far before I felt compelled to warn my best dressed besties!!!) WHEN YOU RECEIVE THIS BOTTLE AND SEPARATE DROPPER TOP: STEP 1 : REMOVE ALL CLOTHING!!!!! (THAT U LIKE) AND STAND ON A SURFACE THAT YOU DONT CARE ABOUT....I HIGHLY RECOMMEND THE LAWN OR GRAVEL!!! (just gently removing the plug from the bottle absolutely DESTROYED a $250 pant suit I happened to be wearing and also irreversibly stained the tiles and sink in the hotel I happened to be staying in) ...(so, REEEEAAAALLLLYYY EXPENSIVE LESSON LEARNED!!!!) Turns out that NOTHING will remove the stain once this substance has contact with ANY SURFACE!! I still am convinced it's an extremely good and beneficial product (my coworkers who use it regularly swear by this brand) ...but they're not neat freaks and don't wear luxury clothing....so I just wanted y'all to get the warning I didn't. 😂🤗 great product but don't open unless you're naked standing in gravel or in the shower or if you're looking for an excuse to replace your entry shower tiles!! 🤣😂🤗 I'm laughing but simultaneously trying to settle with the hotel...DO NOT LET THIS HAPPEN TO YOU!!! Just put a towel over it and open it far away from any indoor space and don't ever let this product inside your house or near any surface or your clothes. Other than that, I've heard AMAZING things!! I'm pushing forward despite the massive surfactory inconveniences.

I really like the product, and it was delivered in a timely manner

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!!
