Manufacturer statement
XYMOGEN product page says: "We gladly offer certificates of analysis on request" and "our rigorous quality assurance, on-premises quality control laboratory testing for identity, strength, quality, and purity..." However, I did not find an independently verifiable COA for this specific product, and the NSF Certified for Sport registry result I found was for a different product (FIT Whey For Sport Cocoa), not this methylcobalamin product.
