## Description

Product description

Review: Education, not indoctrination - First thing I need to explain is that my background is microbiology, virology and psychology, followed by years as a military intelligence analyst. My day job currently after 40 years is still a data intelligence analyst. So basically I am a professional researcher. As veteran of the '80s and '90s I was exposed to polychlorinated biphenols(PCBs), asbestos, diesel fumes, fungicides, pesticides, untested vaccinations for smallpox, anthrax, and all of the shots that we needed to travel to South America Africa Europe etc. I was what they called a PT Max or PT monster, a super fit, ultra fit long distance, runner, cyclist and swimmer. I benched 350, squats at 550. I weighed 185, with 10% body fat. I exited the service and began my civilian life married with children continuing to cycle run and exercise. By age 34, I suddenly developed type 2 diabetes, COPD, and so much joint pain. For 30 years I've tried everything, but it just got worse. I've never smoked, never had alcohol, not even coffee. I eat only real foods. All of that is to let you know that no matter what we do we don't really have control over things that affect us in our environment by research ability plus my medical background I began to investigate methylene blue. I remember using methylene blue in the lab in college and also putting methylene blue in the punch at parties because it was funny to hear the stories of people the next day who actually went to the bathroom and saw blue. I began 1 drop in 20z twice a day. Micro dose. What I discovered was better sleep quality and pretty vivid dreams. I also noticed energy levels improved some. I avoided the vacx, took hcq and ivermectin during the cov19scam. I was also taking micro doses of mb at the same time. Funny thing is I don't get sick anymore like I used to. I am now using 5 drops in 20 oz, and I put a single drop of Perfect Minerals, because I distill water. Pure water needs a touch of minerals and I know that it helps the uptake of mb. My advice, do your research on a computer, not a phone, as your phone information is filtered, curated and limited. Do not limit yourself to only the first group of articles that you Google get off of Google and go to other browsers due the same research using multiple browsers look for articles from the National institute of health look for articles from Japan, Europe; Spain Italy etc. Read white papers. The media pharma military industrial mega machine wants you sick, weak, sitting in a cube, ordering food and crap, while watching streaming content. Get out of the house, start moving, eliminate canned drinks, by a water distiller, find farmers markets, start a garden. But don't wait until you're in your '60s and have tried the commercial medical industry to help you because they don't want you healthy they want you addicted to their drugs their prescriptions. Methylene blue can be effective, it is easy to use and this brand seems to be a very high quality. Get the book. But get others. Do y'all remember libraries Go there and do research. Or sit in your cube, door dash fast food and watch Netflix. You get to choose.
Review: Ethylene Blue, a gift from 1876. - The patents are expired. The money men have all died. But for a strange twist of fate, Ethylene Blue might have been completely forgotten. It was 144 years later, a crazy criminal syndicate conspired to over throw an election by faking a pandemic with propaganda news, locking the population in their homes during the electioneering, to enable to stretch voting day to a couple of weeks, so they can stuff ballot boxes. Yeah, it’s a lot to take in. But, emergency rooms were sometimes overwhelmed with flu symptoms and other pathogens, where patients were dying of respiratory illness. However, emergency rooms had kept around an old tried and true remedy from the 19th Century, known as Ethylene Blue. As the old saying goes, “When patients are failing, and nothing else will do, reach for the Ethylene Blue.” As it turned into a coverup, as crazy conspiracies do, the manipulators of this plot were trying to suppress the use of other known tried and true methods, doctors were using to deal with this mess. So the doctors, in some cases, had to fly under the radar, and were saving patients with Methylene Blue. Well, word got out as the investigations were underway, eventually, people started talking about their experiences with Ethylene Blue. Word of mouth still works even better in the Internet Age, but by the end of 2022, a ground swell of people, sick of their idiotic prescriptions for symptoms that don’t cure anything, started experimenting with Methylene Blue. If you’re new to Ethylene Blue, this yet another human trial without doctor supervision (like COVID vaccine), you might want be a little cautious. Ethylene Blue’s star attraction is its effect on the mitochondria in every living cell in your body. That’s a wide range of effects. And you might take note of the fact, that everybody’s body is uniquely different. For that reason, unless you’re feeling safe in your assumptions, you may need to ease into this thing like getting into a hot bath. But you’re you, and you’re welcome to use it or not or modify my instructions to suit you. Copy it, distribute it. But I think for first timers, by doing it this way, you’ll learn how little is needed and how effective. This is recommend for first timers, especially if you’re old with issues already. This is assuming you’ve read up on the experiences of others while using it. Start the first day with 1 drop (0.5 mg). Always take in the mornings, with the same drink, water or juice. On the second day, if you’re still inclined, take 2 drops and again on the third day. If after two days on the 2 drops, bump it up 3 drops for three days. Then in that manner, continue to increase by 1 drop every three days. Write down your impressions, if any, at the end of the day. The reasoning behind this slow approach is the unknown half-life for Ethylene Blue. I guesstimate it at 12 hours, give or take 2. That means, if accurate, the blue you took that morning is half gone after 12 hours, and 12 hours later the other half will have halved again, leaving a quarter in your body when you’re ready to take another dose. So you see that it takes time to evaluate the effect on your metabolism, and many have said before, “Little is better.” Of course, I didn’t do any of that in my first experience with Ethylene Blue. No-one told me to. So my experience was to jump around from 10 drops to 36 to 20 to 27, from day to day without really understanding any cause and effect. But I did seem to find better concentration, and a longer attention span. I’m hoping for a lasting improvement, because I don’t want to take this for the rest of my life. But right now, it seems to come and go. Perhaps my perception is clouded by familiarity to the changes. In closing. The accepted formula for 1% Ethylene Blue solution to arrive at the safe range: 1 drop (0.5 mg) to 8 drops (4 mg) per Kg of body weight. That’s a large range. Pounds = Kg x 2.2046. So, to change your pounds to Kg, you divide. (lbs/Kg) Most people will use under 1 drop per Kg. Examples of the low end of the range (1 Drop per Kg): 100lbs = 23 Drops, 150lbs = 34 Drops. Very little is used up in the body. It is only filtered out in the liver and excreted through the kidneys. It supplies electron transfer. Not chemistry.

## Questions & Answers

**Q: Has this company been investigated by the fda?**
A: I don’t know if the company has been investigated but in response to the other two answers. Methylene blue is indeed considered a drug that has been approved by the FDA for the treatment of various medical conditions such as methemoglobinemia and urinary tract infections. It is also often used for diagnostics in various surgical procedures.

**Q: Will this stain my mouth or teeth? How much dilution to prevent staining?**
A: MB 1% solution is as staining as blue ink for an ink jet printer, so yes it will stain teeth, countertops, or your carpet (which happened today for us.) 

However, you can avoid staining your teeth and tongue by purchasing size 00 acid resistant veggie capsules, sold here on Amazon.

Regular size 00 veggie capsules also work, but the AR capsules are thicker, and are white, not clear.  You put 8-11 drops in the longer half of the capsule, then push on the smaller half.

Even AR capsules get soft when filled with MB (or even water, which you can practice with), so be sure to fill your veggie cap over a sink (preferably stainless steel), or outside, just as you would if using ink.

Swallow the capsules and wash it down with water or your favorite beverage.  I use this method myself.

Limeade diluted with water can also be used if you just want to add drops to a beverage.  It hides the taste and is high in Vitamin C.

**Q: They say in the comment that it is 0.5 mg per kilo, so that means I have to use if I weight example 68k I have to use 34 drops of this bottle perdose?**
A: When the manufacturer states that a drop has 0.5 mg and there are 1000 drops in a bottle, he is using the technical definition of a drop, which is 0.05 ml. In reality there are 400-500 drops in this bottle using this dropper (half as many). A drop in reality is not the same thing as a technically-defined drop, because different fluids have different densities and surface tension, and dropper sizes vary too. There are 500 mg in this bottle and roughly 500 drops in reality. So a drop in reality is roughly 1 mg, or a little more, 1.25 mg. So if you are targeting 34 mg, then I think you’re correct, roughly 34 drops of this bottle using this dropper.

**Q: What is the difference/benefit with ordering the 0.5% and the 1% methylene blue?**
A: One drops of 1% is equivalent to 0.5mg methylene blue, for example, I use 8 drops (4mg) dosage for best mitochondria action. If 0.5% solution is used, then it needs to be 16 drops instead of 8 drops.

### ⭐⭐⭐⭐⭐ A Game-Changer for Energy, Mood, and Sleep!
*by B***R on May 31, 2025*

I’ve been using Compass Laboratory’s Methylene Blue (1% USP-Grade, 50ml) for a few weeks now, and I’m blown away by the results. As someone who’s always looking for science-backed ways to optimize my health, this product has exceeded my expectations in every way. The pharmaceutical-grade quality and third-party testing gave me confidence to try it, and I’m so glad I did! Health-wise, this methylene blue has been a fantastic addition to my routine. Its ability to support mitochondrial function has noticeably boosted my overall vitality. I feel more resilient and less sluggish, even on busy days. The antioxidant properties are a huge plus, as I feel like I’m giving my cells the support they need to stay healthy and combat oxidative stress. When it comes to sleep, I’ve noticed a significant improvement in quality. I fall asleep faster, and my sleep feels deeper and more restorative. I wake up feeling refreshed, which is something I haven’t experienced consistently in years. The vivid dreams are an interesting bonus, but the real win is how rested I feel. Mood-wise, I’ve felt a subtle but meaningful lift. I’m not dealing with clinical depression, but I’ve noticed I’m more focused, motivated, and emotionally balanced. It’s like a mental fog has lifted, making it easier to tackle daily tasks with clarity and enthusiasm. The energy boost is equally impressive—unlike caffeine, which gives me jitters, this provides a smooth, sustained energy that keeps me going without crashes. The dropper bottle is convenient, and the liquid form makes it easy to measure precise doses (I started with 1 drop in water twice a day, as recommended). Yes, it turns your urine blue, but that’s harmless and expected. The taste isn’t great, but mixing it with a flavored drink helps. Compass Laboratory’s commitment to purity (no formaldehyde or heavy metals) and USA-made production makes this a brand I trust. If you’re looking to enhance your energy, mood, sleep, and overall health, I highly recommend giving Compass Laboratory’s Methylene Blue a try. Just be sure to consult your doctor, especially if you’re on medications like SSRIs. This has become a staple in my wellness toolkit, and I’ll definitely be repurchasing!
