From what I can tell this is desertcart's fault, not really the seller's so I cant fault them. All i can say is packaging could be better for overall product durability.... along with desertcart drivers not feeling the need to toss small packages onto the ground -_- ... Be warned there is no refund/exchange/return policy on this product through desertcart. With that out of the way, onto the good! I highly recommend this brand. Ive been using methylene blue for about a year now and have flip flopped around a few brands trying to find the best bang for the buck while making sure its actually 3rd party tested. This stuff so far takes the cake. Everything I expect out of a S tier methylene blue product without the highway robbery on pricing. These (2x) 100ml bottles are the equivalent of almost 14 bottles of meraki blue while being equally as pure and potent when comparing apples to apples. If youre reading this thinking about buying MB for the first time, I highly recommend also purchasing some of the nutricost brand vitamin C and NAC. Vitamin C turns methylene blue into leukomethylene blue (LMB). Which more has been shown to be more efficiently at the cellular level and crossing the blood-brain barrier. The NAC has helps your body produce glutathione which aids in detoxification aling with curbing the mild oxidative stress caused by MBs improved mitochondrial electron transport For beginners, start very very small, even if you feel no effects. Start with 1mg and slowly over several days go to 2 and 3mg until reaching the desired effect. You need to kind of temper your body to it for best result without side effects. In 6-8 Oz of water add 1-3 mg (~2-6 drops respectively of 1% solution) with a half scoop/serving of both vitamin C and NAC stir till dissolved and let it sit for about 10-15 minutes. Slowly and steadily increase dosage until you begin to notice the increased energy without exceeding 20mgs per day (i still dont exceed 10mgs a day). You now have the best all around known methylene blue experience to date. (All three products are less than $75 total and will last you well over a year). Review: Great value but monderate the dosage. 2 to 3 drops per 16 oz ruffly. - Bought this for a friend and he loves it. Comes with two large bottles that should last a year if used as directed. 2 to 3 drops seems to work great for a reg size bottle of water. Maybe a couple more for larger bottles. If you use to much it will start to turn your mouth and teeth blue. ## Features - 1% Methylene Blue trihydrate, demineralized water.

I am using it for my prostate and it seems to help. When Amazon sells a medicine, there should be SOME vetting of the product. Otherwise, it's snakeoil. ## Frequently Bought Together - 2X Methylene Blue 1% Solution | 2X 3.4 Fl Oz - 2X 100 ml | Ultra High Purity | Pharma Grade Ingredients - Third-Party Tested | Formaldehyde Free | Set of Two | Heiltropfen® - The Ultimate Guide to Methylene Blue: Remarkable Hope for Depression, COVID, AIDS & other Viruses, Alzheimer’s, Autism, Cancer, Heart Disease, ...
