New improved formula! Now neutral in colour instead of the previous blue colour. The new formula does not discolour clothes or skin. A unique formulation to ZipVit, combining ingredients associated with muscles and joints. Emu oil was traditionally used by Aborigines and Bushmen in Australia for soothing and healing. Other ingredients include Glucosamine, Chondroitin, Wintergreen and several essential oils. Just the product to get you running again!Amazing product. I have tried other pain relieving gels from other companies without success. Yours is the most effective by far and I will be recommending it to my friends. May I also say your call centre people are very friendly; keep up the good work.Mrs Ainsworth, (Kettering)
