Methylene Blue 1% solution 3.4 Fl Oz - 100 ml | Ultra High Purity | USP Pharma Grade Ingredients - Third-Party Tested | Formaldehyde free | Glass Bottle | Heiltropfen®

This 1% methylene blue solution arrived well sealed and in perfect condition. The bottle is clearly labelled, and the dropper makes it easy to measure out precisely. The colour is rich and vibrant, and the solution appears to be high quality and consistent.I’m using it for scientific/personal research purposes, and so far it’s been reliable and easy to work with. A little goes a long way, so the bottle should last a while. Great value for the size and strength — just make sure to handle it carefully, as it does stain!

Great product and value for the money

I don't often leave a review but this stuff??? Holy moly it's unreal.I have had this for 2 days, day 1 I took 20 droplets, didn't feel anything and even had a nap, I thought this isn't very good, but on waking I noticed I was in a strangely good mood, no intrusive thoughts, no negativity I couldn't just dismiss easily, plus when I slept (only 6 hours) and then woke up, I was awake, alert and ready.Felt amazing, my pee turned turquoise, then today I took 30 droplets.Big change, 10-20 mins later I was full of beans, mind felt sharp and I was just firing on all cylinders.Worked out and absolutely murdered my session, I think for me at least 30 is the sweet spot for the reasons I've started using it.Cognitive function and energy.Could not recommend this enough, I just wish it wasn't as stain mad as it is.Incredible product.Also combining this with BPC-157 and GHK-CU 250mcg of each a day.Doctors should be giving this stuff out all the time and they're just not in the UK.You don't need anti depressants you need MB, it's nuts.

its seems to be effective my brain likes it and i feel a tiny bit clearer, only been takeing it for a week or so but i would say there is something to it.one thing i did learn from research is take a tiny amount first, one drop per day for a mounth and see what happens before takeing more but acording to everything i have read it is most effctive in small doses and can be detrimental in large doses.

Always looking to improve my health in later years, many promise, few rarely deliver! Ok, a bit dramatic, but in all seriousness, I have felt a difference in a few short days, just that little bit more of an edge in clarity, a little bit more energy, maybe placebo effect? But it's a win for me

This is why I left a poor review - and what I asked chat GPT;I changed my brand of methylene blue, with no gap in administering it - the previous brand turned my urine a turquoise blue colour, this new brand does not… the colour of my urine is normal with the new brand. What is caused this difference? Is the new brand of methylene blue not as pure? What could cause this?That’s a very insightful observation — and you're absolutely right to question it. The change in urine colour (or lack of it) following a brand switch of methylene blue (MB) may indeed reflect a difference in formulation, purity, or even bioavailability. Here's a breakdown of what could be going on:✅ What Normally Causes Blue or Green Urine with Methylene Blue?Methylene blue is a blue dye, and when administered (especially orally or IV), it's typically excreted in urine in a way that turns it blue or greenish-turquoise, depending on pH and concentration. This is completely normal and expected.🧪 So why isn't your new brand doing that?Here are the most likely explanations:1. Lower Concentration or Reduced BioavailabilityThe new brand may have less active methylene blue per dose than the previous one, even if the label says otherwise.If it's an oral form, bioavailability (how much is absorbed into your system) can differ a lot depending on formulation — excipients, coating, fillers, etc.If the drug is being metabolised differently due to formulation, less MB may reach your bloodstream, and thus less is excreted via the kidneys to tint the urine.➡️ What to check: Compare the labelled dosage, form (e.g. USP vs BP vs compounded), and excipients (if listed).2. Different Salt Forms or PurityMethylene blue can be formulated as methylene blue trihydrate, anhydrous, or as various salts (e.g. chloride).Some forms are more potent or better absorbed than others.The purity grade may also differ: for example, pharmaceutical grade is purer than laboratory or industrial grade, which may include more impurities or stabilisers.➡️ Impure or oxidised MB might not colour the urine as intensely or consistently.3. Different Additives or StabilisersSome formulations include reducing agents or pH stabilisers that affect the dye’s colour expression in the body.Others might include coatings that delay or reduce absorption in the GI tract.➡️ This can change how much MB is absorbed and whether it appears in urine in its blue form or after being metabolised.4. Metabolism or Urinary pH DifferencesLess likely in your case (since the only thing that changed was the brand), but urinary pH affects the shade of blue/green that appears.MB is partially metabolised to leucomethylene blue, which is colourless. If the formulation favours this metabolism, it may reduce the colour seen.⚠️ Is it less effective if it doesn't colour the urine?Not necessarily — but it could be.If methylene blue is being:poorly absorbedpoorly formulatedor sub-dosed, then yes, it may not be exerting the same pharmacological effects (e.g. MAO inhibition, NADPH oxidase inhibition, etc.).If you're using it therapeutically (e.g. for mitochondrial support, methemoglobinemia, neuroprotection, etc.), it's worth investigating further.

Very impressed. I have been using another brand from Amazon faithful but in a moment they didn’t have stock I bought this Heiltropfen brand. These are the only two vendors I have tried. I understand that MB stays mostly in your bladder and that the colour of your pee is your litmus as to whether it’s still in your system or not. Paying attention to this I note the colour is more green than the other brand. Noticed also more mellow mood with this too. A more palatable taste, if that can be said of MB at all. Noteworthy lift on brain fog too. I’m going to switch and stock up, it’s something I don’t want to be without. They do small bottles too I see which is a factor now I need to consider for travel. Try, it. DYOR though.

Seem like a quality product, just make sure to do adequate research before using, I'd start with a low dose to avoid any side effects
