  • Gets the job done
I’m purchasing my 6th bottle. This brand is the best I found for size/price and it’s effective. I initiated with a 30 drop dose twice a day for 30 days and now maintain with 2 droppers full (roughly 30-45 drops) daily in juice. I’m 128 pounds. I mix in a dark coffee cup with a metal straw and use it to drink the concoction as well, to bypass my teeth. Although while on vacation I didn’t have the straw and the blue stains disappeared within a few minutes, so I’m not sure the straw method is necessary. Definitely do not put it in a capsule. It needs to coat the throat and all the way down the esophagus to mix with stomach acid to be most effective, which will also ensure the microbiome in the small intestine is not disrupted. Also it’s well absorbed in the mouth and easily crosses the blood brain barrier through the oral mucosa. During my loading period in the first 30 days I noticed a lot of positive changes. Especially with energy, mood and overall better digestion. I had a couple days of stomach cramping and strange poop but compared to everything I had been through, it was minor. And expect periodic blue or green urine. Now feeling energized is my new normal, so I don’t recognize huge improvements anymore. I haven’t missed a daily dose for 7 months so I can’t report the lasting effects after stopping. I battled Lyme and other autoimmune issues for years that I resolved 90% of the way with herbs, ivermectin and fenbendazole. Adding methylene blue was the final step to total freedom. I listened to every podcast and audio book on it that I could find and jumped in with both feet. I only had positive things occur after starting it and have recommended to MANY people that report similar success stories for various health issues. Hopefully this review finds someone that needs to hear it!! I was at my wits end with my health in 2018 and know how devastating it can be when you are trying to heal yourself and mainstream allopathic medicine continues to let you down. Often saying tests are inconclusive and nothing can be done! Or they try to prescribe various pharmaceutical meds to put a bandaid over symptoms instead of treating the root cause - which I refused to take. I’m living proof that something can indeed be done. I have my life back ALL OF IT and will be forever thankful. ... show more

  • affordable quality product
Arrives well-packaged. Product appears clean with no unusual odor, taste. Price is significantly better than other brands available presently with no apparent decrease in quality.

  • Fixed my tinnitus extra energy bonus
So this fixes my tinnitus in my ears. I’m a big guy so it took getting over 20 drops to do it. Increases energy but did notice a slight difference in the effectiveness of my nitric oxide. It helps to take this in morning and early afternoon doses as it can make it a little harder to fall asleep if you take it too late. ... show more

  • Depends upon your current condition.
I like it. Has some perceivable positive effects with little stomach upset. The blue pee can be fun. Too early to tell if it is a 5 star product. Going to try some other reputable brands. This is one of those products that will depend upon your current condition. Your absorption and utilization. If you are doing great than it is a good product for health and longevity. If you are not doing so great, if may help you out of a rut. It may give you that boost and time to figure it out. Then make all the other necessary changes to maintain good health and happiness. ... show more
