Review: Excellent Quality and Effective - I recently purchased the 2% Methylene Blue (3.75 fl oz) from this brand, and I’m extremely impressed with the product’s quality and performance. Packaging: First off, the glass bottle is a nice touch. It feels premium and gives a sense of reliability that plastic bottles sometimes can’t match. The dropper is precise and easy to use, ensuring I can apply just the right amount every time. The cap seals well, and the bottle is sturdy and not prone to breaking, which is great for a product that’s likely to be kept for some time. Concentration & Effectiveness: This 2% Methylene Blue solution is ultra-concentrated, which means you really don’t need much to get the full benefit. It’s perfect for anyone who’s looking for a highly concentrated form of Methylene Blue without needing to dilute it themselves. I use it for cognitive support and I’ve definitely noticed the effects. It feels like it’s working quickly and effectively. USA-Made: It’s also great knowing this product is made in the USA. I prefer to support domestic manufacturing, and the fact that this is made locally gives me confidence in the production standards and quality control. Versatile Use: I’ve used it for cognitive enhancement and it’s been super easy to integrate into my routine. I appreciate the precise dosing the dropper provides, making it easy to get the exact amount I need without any mess. Value for Money: Given the high concentration and quality of this product, I think it’s an excellent value. The 3.75 fl oz bottle goes a long way, and I’m confident this will last me for a long time. Overall: If you’re looking for a high-quality, ultra-concentrated Methylene Blue, I highly recommend this product. The USA-made quality, combined with its effective concentration, makes it a standout in the market. The glass bottle and dropper are just the cherry on top, ensuring a clean and easy experience every time.
Review: Consistent, Quality Methylene Blue - I have been taking this Methylene Blue for about a year now, so I felt it was time to give a review. Overall, I'm very pleased with this product and brand and have found it consistent for the 3 bottles I have purchased and used. All the 'signs' of it being actual MB are there (stains anything you get it on, will turn urine blue/green, etc) and I have felt better using it each morning. MB does not taste great, so I tend to add it to my morning beverage of choice (works well in bitter or flavored carbonated beverages like coffee or colas). I have heard of others using it in soups and such but I've never put that much work in. My typical daily dose is one full dropper (10 drops), or 50MG - note, I worked up to that. To anyone new to MB, I would start with a few drops and find the dose that works for you. Tip: This dose go on sale every now and then (not often), but I find it lasts so long, I just put it on subscribe and save and find the value good at this price point.

### ⭐⭐⭐⭐⭐ Methylene blue saved my life.
*by E***A on January 16, 2026*

Excellent quality producing youthful energy levels... I have massive head trauma, from my time spent serving in a combat unit. Five hour knaps were common. Methylene blue saved my life. Of course, I was extremely reluctant to try the blue. I am certainly grateful for the 2% blue.
