I have been buying this product from Omax for two years. I used to have muscle cramps in my adductor muscles that were so severe that I couldn't even walk it out. I started using the CBD menthol roll on and my muscle cramps have virtually disappeared. Then I started using it for back and neck pain from years work our working out and when I wake up in the morning I feel great! Even bought some for a friend. Awesome product and good customer service.
