In Continous Production Since 2012.
Our methylene blue is an analytical calibration grade. That means it has to be ultra-pure and pure enough to calibrate highly sensitive equipment accurately. This purity level exceeds the standards required by USP and FDA requirements for injectable (pharmaceutical grade) methylene blue.
Disclaimer: Methylene Blue is not a nutritional supplement, and if we disclose usage guidelines for application in humans or animals, the FDA would reclassify our product as a drug and force us to take it off the market. We can not label this product as pharmaceutical grade because the FDA has only approved one brand of IV methylene blue to receive this designation.
