Methylene Blue Pharmaceutical Grade 2oz– USP Grade 1% Solution with Balanced Electrolyte SolutionThird-Party Tested Brain Health Supplement for Humans –No Formaldehyde High Cognitive Support

I bought this out of curiosity and I was really surprised. After a few days, I started feeling more focused and clear — like my brain just works better. I’m a mom, and most days I feel tired, scattered, and just mentally foggy. I decided to try this methylene blue to see if it could help, and I’m honestly so glad I did. After a few days, I noticed I felt more clear, more focused, and not as drained by midday. It’s easy to use, doesn’t have any weird aftertaste or smell, and I love that it’s tested and clean. I’m not into supplements usually, but this one is staying in my routine. It really made a difference.

I’ve been using this Thinbi Methylene Blue for a couple weeks now, and I’m honestly loving it. I bought it mainly for the cognitive support, and I can already tell a difference—my focus is sharper and I feel more mentally “on” throughout the day.The dropper makes it easy to use, and I like that it’s a pharmaceutical-grade formula with no weird additives or formaldehyde. It’s also third-party tested, which gives me peace of mind about the quality.I just take a couple of drops in the morning, and it gives me a noticeable boost without feeling jittery or wired. Also, no bad taste or side effects, which is a win!Definitely recommend if you’re curious about trying methylene blue and want something clean and trustworthy.

Ultimate Methylene drops have become an essential part of my daily routine! I take them every morning diluted in water, and the difference in my energy and focus is unbelievable. Within minutes, I feel more alert, clear-headed, and ready to take on the day.I absolutely LOVE the vibrant blue color — it makes the whole experience feel fun and unique, almost like a little daily ritual that energizes both my mind and mood. These drops are truly incredible. If you’re looking for something that actually works and helps you stay sharp and energized without the crash, this is it. Total game-changer! 💙

Thinbi’s 1% Methylene Blue has quickly become a staple in my wellness routine. The purity and consistency of the formula really stand out — it’s reassuring to use something that’s pharmaceutical grade and clearly designed with quality in mind.Another big plus is what’s not in it: no harsh chemicals, no GMOs, and nothing that might trigger allergies. That kind of clean formulation is hard to come by. The concentration is just right for easy and accurate use. For anyone into health optimization or cellular function support, this is definitely worth considering.

I will post changes throughout my testing of this first thing in the morning.First impressions is that the product is highly concentrated, just one drop in a clean glass of water can really make the whole thing blue. It was warm when I got the package so I assume it was under the sun for a bit and I'm not sure if this will affect its properties. The bottle and the label looks high quality. Content of bottle was full.Day 1 (5 drops):No taste really, and no evident changes whatsoever.Day 2 (10 drops):The taste is now evident and kind of metallic. I think I experienced a bit more energy during my day, and at night my eyes were pleasantly heavy that I felt it aid to my sleep. At the next morning I had to go to the bathroom though, I think it promoted my digestion.Day 3 (went back to 5 drops to increment by 1 so 6 drops):A slight boost on my energy levels during my day, and somehow slightly clearer thinking feeling. I noticed my mood was a little more towards the happy side but I also just recently graduated from College so a lot of responsibilities and weight were dropped so unsure of its relation with this more peaceful chapter in my life.Day 4 (7 drops)Energy levels seems normal now. Clear mind for multitasking, barely noticeable though, I hope that with larger dosis the effect will be more powerful.Day 5 (8 drops)You have more energy during the day and consequently more desire to rest at night with heavier sleep. I think also you are willing to do more stuff, you feel the need to spend the extra energy and tackle bigger tasks.Day 6 (9 drops)Probably due to the extra effort but evidently I find my self super thirsty. Clear minded.

I’ve been using the USP Grade 1% Methylene Blue solution from this brand and have been genuinely impressed by its quality and effectiveness. Within the first week, I noticed greater mental clarity, improved focus, and a steady boost in overall energy. The inclusion of a balanced electrolyte blend is a major advantage—it truly supports cellular hydration and enhances overall well-being.What I appreciate most is the transparency and safety behind this product. Each batch is third-party tested, which gives me complete confidence in its purity and potency. The fact that the formula is formaldehyde-free shows a serious commitment to clean supplementation and customer health.The high purity of the solution also supports mitochondrial function, and I can definitely feel the difference—better stamina and less fatigue throughout the day.I highly recommend this product to anyone looking to enhance cognitive performance, support brain health, and increase daily energy naturally and safely.

I was a bit skeptical before trying this but let me tell you. It exceeded all of my expectations! I’ve only been using it for about a week but I already feel like I’ve had much more mental clarity and more energy. I was looking for something to help with energy levels that wasn’t caffeine and this does the trick! Great product!

So far I am loving this product! Aside from the fun, vibrant color which makes me happy, I have had more energy and just felt really good on it. It has no taste when you're drinking it; maybe the tiniest bit of aftertaste but it's not bad. I'm excited to see more positive long term effects as time goes on.
