Heisen Blue Avis 

Eexcellent product, shipping and handling were very porfesssional

I've been using it on and off for a few months now and I can honestly say there is a significant difference in both brain fog, concentration and energy. This is coming from a person with sleep apnea who uses an annoying cpap machine. Dont get me wrong sleep apnea is a serious condition and you can die in your sleep if serious enough. But, I pivot use it when my gf is sleeping over, she can't stand my snoring. The cpap machine also provides me with energy and I wake up earlier, since it pushes air through you all night lol. Anyways, the heisenblue does the same thing for me and more. I'm not advocating to not use cpap, for those that need it... Use it! But in regards to my own experience, I think heisenblue is great, especially considering methylene blue is used as an antidote to treat methemoglobinemia(lack of oxygen in blood cells). So for me it works perfectly, I get oxygen from it, instead of using my cpap. But who knows I could die in my sleep....(knock on wood I dont).

I'm still in the process of researching the product. Contacted customer service in order to return the order. They replied very fast and offered to keep the product. I am very satisfied with their communication and support.

It’s helping me so far and I like taking it

Great Product. Best I have used and fast shipping. Love the results

Great product and good to see an accurate and verifiable COA. Product does what it says it will do.

5 STARS ALL THE WAY! Both my husband and I are enjoying all the benefits of this amazing product!

Did not notice much of a change at all and never got more than a slight green tint in the urine.

I think you're methylene blue works great and I'm on my second bottle. I'm 65 and it's hard to find something besides caffeine to keep you going, and your methylene blue helped solve that problem. Thank you, I'll be ordering a third bottle soon, have a great day stay healthy, Matt.

I tried several other brands but nothing else touched the quality of Heisen blue..

A solid product and a solid company.

The "REAL DEAL" this gives me sustained energy throughout my workout.

I've tried several different methylene blue suppliers of methylene blue. Heisen Blue is the best. Quality, purity, honesty, Canadian, and integrity. Blue pee people rock. I've also noticed that I use less insulin.

Unfortunately, I was unable to take this product due to a medical condition. However, the company very generously refunded me my money, no questions asked. I so appreciate them understanding and being so courteous. Thank you!!!!

I can tell when my brain is “off.” I take 10 drops of HB, and I’m back to normal.

I was set up for a return, but a representative said there’s something wrong on their end so just keep it. Then I got an email from someone else that said they were gonna report me to the fraud department and I responded saying I was gonna let my girlfriend try it as she suffers from Alzheimer’s and that he better be real careful who he accuses of fraud.

My parcel broke, and instead of replacing or contacting me I had reach out after 2 weeks.

Even though the delivery company had notified them they did nothing to rectify the situation. I thought they would just resend. Nope just crickets.

Fast delivery, clear dosage instructions and it seems to work.

Great product nothing added unlike some other brands. The best.

Fast delivery of a quality product. Can feel the energy boost within days of the first application. I've found a dropper full to work best.
