When you first take it you will almost feel high. But as you take it daily that feeling goes away. It's amazing how my mental clarity and just overall feeling has improved. I feel more motivated than ever to commit to my life's goals. Quick tip. This stuff is extremely bitter and will stain anything it touches, especially the tongue. And you'll need to scrub all day to get it off. So what I do is get empty clear capsules and put it in there. It solves all the problems. Overall highly recommended. This brand is also one of the few that has a 2% concentration. So it's double the potency of other popular brands. Another small thing to point out is it may make your pee stream weaker at first. This goes away as you take it. But I recommend drinking a little extra water with this product. Also it will turn your pee either blue or green depending. This is normal so no worries! ## Features - 2% ULTRA CONCENTRATION: Less Drops to be Effective and double the amount of anyone else. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CV5QBFT7 | | Best Sellers Rank | #3,173 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2 in Analytical Reagents | | Brand | METHYLENE BLUE CO | | Brand Name | METHYLENE BLUE CO | | Container Type | Bottle | | Customer Reviews | 4.2 out of 5 stars 1,245 Reviews | | Included Components | 1 Bottle | | Item Form | 2% Solution | | Item Highlight | Ultra concentration formula, heavy metals tested, laboratory reagent grade, sealed vial, analytical research application Item Highlight Ultra concentration formula, heavy metals tested, laboratory reagent grade, sealed vial, analytical research application See more | | Item Volume | 100 ml | | Manufacturer | Methylene Blue Co | | Model Number | Ultra 2% Solution | | Package Information | Bottle | | Part Number | MBCO-ULTRA2 | | Purity Percentage | 99.9 | | UPC | 676753994059 | | Volume | 100 ml | ## Product Details - **Brand:** METHYLENE BLUE CO - **Item Form:** 2% Solution - **Item Volume:** 100 ml - **Package Information:** Bottle ## Images ![Methylene Blue 2% Pharmaceutical Grade Solution 3.75 fl oz USA Made - Image 1](https://m.media-amazon.com/images/I/71W8FqZP22L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Quality and Effective *by A***N on September 28, 2025* 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.

This is normal so no worries! ### ⭐⭐⭐⭐⭐ High quality MB product, made in the USA 🇺🇸 *by E***M on May 8, 2026* I purchased this brand of 2% Methylene Blue because this is the brand that Dr Boz uses. I’ve been using a different brand. Compared to the other MB product tried, it was well packaged & arrived intact given the material is in an opaque glass bottle. Microplastics are becoming a concern and I appreciate the glass packs for the MB.. This 2% MB solution is a more concentrated solution than many on the market. When I first started taking the same concentration of a different brand at the recommended dosage, I notice it tasted absolutely vile & didn’t see any of the reported results others were reporting but when I baked off to 5 drops in about 8 ounces of 💦 , boom - what a change. I prefer to support domestic 🇺🇸 manufacturing, but if they are doing stupid stuff, I will source internationally. I tried it for cognitive enhancement and though it was easy to integrate into my routine, I didn’t notice any 🧠 changes. What I did notice was that when I didn’t use it on a recent weeklong business trip, an issue that I hadn’t notice had not been prevalent reared its ugly head again. Getting back in the groove of using it has beat that issue back again. Value for Money: Seems comparable to the other brand of MB that I’ve been using. Overall: This is not a paid review. You can read my other reviews - I leave 1 ⭐️ reviews as well as 5 ⭐️ - I spend my own money on these products & many of them I have on subscription. ## Frequently Bought Together - 2% Methylene Blue 3.75 fl oz, USA Made Ultra Concentration Glass Bottle and Dropper Pharmaceutical Grade for Humans Nootropic Supplement - Heavy Metals Tested - The Ultimate Guide to Methylene Blue: Remarkable Hope for Depression, COVID, AIDS & other Viruses, Alzheimer’s, Autism, Cancer, Heart Disease, ...
