Methylene Blue 1% Solution 33.8 Fl Oz - 1000 ml | Ultra High Purity | USP Pharma Grade Ingredients - Third-Party Tested | Formaldehyde Free | Glass Bottle | Heiltropfen®

Great quality. Super pure. Very blue. Be careful, it'll be hard to get the stains out. Very effective for what I need. Very easy to use when mixed with juice.

Great price. This company has high quality. Buy several different items from them. First time buying Methylene Blue. Working great for me.

Its Big, its Safe and its Worth every penny!! Very pleased with my results!

Methylene blue is my new favorite supplement and this is my favorite company to get it from.

This is an awesome value and great product...hands down the best deal. Why the 4 stars? Because this stuff is a Nightmare if you don't have the proper tools. First you need to have a small bottle with a dropper. This stuff is supposed to be taken with drops. After reading the book on this...I use 20 to 30 drops per day. I already had the bottle from a different brand so I was just going to refill it with this. HA...Good luck. You MUST order a glass or metal mini funnel to do this. I tried over my kitchen sink, it spilled and nearly ruined my stainless steel sink. This is Blue INK. It took me 30 minutes with goof off to get the blue out. This bottle should include the dropper bottle and the funnel. I am just giving you the heads up. This is a fantastic product and the best value on amazon...and it was packed perfect for shipping. Just understand that #1 you need to have a smaller bottle with the eyedropper for the daily use. #2 You will need a funnel #3 Pour this stuff into the smaller bottle outside in the yard...do not do it inside or where anything can be harmed. You will spill some and you will be furious. Blue ink on anything is not fun. Blue ink in the lawn...who cares. I am going to say it again. WHEN YOU REFILL A SMALLER BOTTLE....DO IT FAR AWAY from your house outside on the lawn or in the bark dust. I would also recommend rubber gloves. This is BLUE INK. You get it on anything...it is NOT coming off. Clothes, hands, driveway. Now that I have learned the hard way...I hope this helps you. I have all of the items now...I hope this helps and stops any frustration.

Everything good

Wow! It WORKS and now, so do I

I was paying for the little bottles. This makes me feel great the same way the small bottle from another company did. A+ use it for me my chickens, my dog. We are all on it.

excellent, porduct,its a real game changer for me daily

I ordered the 1000ml Methylene Blue primarily for personal research purposes related to cognitive enhancement and mitochondrial support. The product arrived securely sealed, clearly labeled, and the deep blue color indicates high concentration and purity. It dissolves well in distilled water and has been consistent in quality with each use. I’ve been microdosing under careful guidance, and have noticed subtle improvements in focus and mental clarity. As always, anyone considering this for human use should do thorough research and consult a qualified professional, as this is not officially sold as a dietary supplement. Great value for the amount—just handle it with care, as it stains easily and requires precise dosing.

This product is good quality

Great product. I purchased smaller bottles with the pipper in, and some longer disposable plastic pippets, so I draw the liquid out of the big bottle into the smaller ones. Tip: do this over your stainless still sink, as this is a dye. Using 5 drops every other day, and the energy levels are unreal. Took down a large tree in my front garden the other day, and fug out the roots. Would nether been able to do that previously. Well not in time I did it in.

C'est un de mes meilleurs achats, un produit de grande qualité et à prix économique. Cette quantité de 1000 ml me permet de transvider avec un petit entonnoir en acier inox dans une petite bouteille que j'ai déjà. De plus le colis reçu était emballé de façon ultra sécuritaire comme je n'avais jamais vu. Je recommande en tout points cet article. Il est cher à l'achat mais vous sauvez le double au long terme.
