TRU Muscle and Joint Cream is a safe, effective, high quality product, which works quickly when applied. It contains all Natural ACTIVE Ingredients, which have science based information backing up there use in the product. It also contains several essential oils that help carry the active ingredients to the painful and inflamed area. Works great for bruises, body stress, muscle soreness, spasm, inflammation and joint pain. I highly recommend TRU MUSCLE & JOINT CREAM.
