ActivOn Is a great product for the relief of muscle pain. It is a topical analgesic. It comes in a roll up tube. I have ultra strength. This deep, penetrating relief is to be applied directly where it hurts. It is safe and effective. I like this product because it does not have the bad fragrance that so many of these products do. It does not burn and did not iritate my skin. You can see more about this product at www.activ-on.com . It is not recommended for children under twelve years of age. My product size is two oz. I can say that it lasts a very long time, so it is a great value for your money! I also like this product because it can be applied directly to the forehead, if you are suffering from headaches. It does contain menthol. I hated those messy gels and ointments. They were never good for travel, or using in public. This great roll on is so easy to use. It does not drip or stain your clothes. Its lightweight and in a plastic container, and very easy to use anytime.
