I received Zim's Max-Freeze Continuous Spray in return for my unbiased review. Zim's Max-Freeze Continuous Spray is a greasless spray that's used for relief of pain in muscles and joints. Among it's ingredients are organic ilex & aloe, arnica, vitamin e and tea tree oil. It's effective in relieving pain from sore muscles & muscle sprains, back, shoulder, neck pain as well as painful hip, elbow & ankle joints. This spray has a vanishing scent so you don't have to worry about walking around smelling like medication. I've used this spray for my 17 year old's muscle soreness. He seems to always come home complaining of calf and hip soreness after running during practice. This spray was really effective in relieving his pain. It's very cold when applied but absorbs quickly. It seemed to give my son relief fairly quickly and lasted awhile. We're impressed with this spray and will definitely get more use out of it.
