I received the Muscle Rub product approximately two months ago. Up until that time I had been using either Biofreeze and or a similar type of product that included more than just CBD. Since then, I have had the opportunity to test this product on my shoulders, back, knees and ankle. The results were surprising. In each case, I experienced significant relief of pain within 30 minutes of application. I have highly recommended this product to all my friends and family members. I will continue to use this product and purchase as necessary.
