Disappointed! It wasn't strong enough ! Very weak formula . it doesn't appear to be as powerful as many years ago . I applied it to my aching lower back and its not what I had anticipated and I really like McNess ,but this product I will not purchase again McNess Store Response: Thank you for your comments Brad. I'm sorry to hear that the Mentholated Wintergreen Oil is not working for you. I can assure you that it is the exact same formula that has been produced as Pain Oil for decades.
