Heisen Blue is a legit high quality methylene blue. I noticed clearer thinking, reduced brain fog, better focus, and smooth, clean energy. No jitters or crash. It genuinely helped me stay locked in while studying, and I’m confident it helped me pass my final exams. This stuff is the real deal.

Great product and great service

High quality product!!! Can't wait for the powder to arrive.

Love Heisen blue! Great customer service. I take this everyday and it has drastically improved my mood and energy levels. I am able to handle and complete tasks without hesitation and procrastination is no longer something I struggle with when I take this stuff. Highly recommend methylene blue to people suffering with mood and motivation issues.

Product appears to be as advertised and received quickly.

after trying many different brands Heisen is the first real one .

I paid for it and have not received it weeks and weeks later

Nothing about my experience has disappointed me so far; all the usual…placing order was easy & received it in a timely manner without glitches; I ordered MB hoping to help with long term low energy & within a couple of weeks I started feeling higher peaks of energy dotted throughout my day; overall experiencing more focus & clarity; but I feel I haven’t been taking it long enough to be certain the effect is real & not a placebo…yet I’m hopeful & will be watching in months ahead to be able to definitively see permanent improvement.

For the methylene blue 1%:

"COA 143984 is accurate. On the other two 146367 & 146368 the methylene blue results have been altered from what we provided to the customer."

I contacted the lab directly and that was the lab manager's response to me.

inflammation gone, energy is steady all day long.

Packaged beautifully. Have yet to use it, but I reckon it will be just as effective as all the USP Grade MB’s.

This product has really helped my brain fog and increased my energy levels

I have using this product for about 3 weeks now, after the first 3 days I noticed a significant change in my energy levels and when playing brain games I am more focused and I am surpassing my high scores previously set. I would highly recommend this brand and product.
