Extremely effective for human athletics and is just as good for equine athletics. The -78 degree co2 cold spray is applied locally to ligaments and muscles for a short period of time! 2 to 4 minutes per treatment depending on the area being treated. The cooling effect creates increased blood flow to the treated area, helping damaged tissues to recover faster. This can be used for tendon injuries, muscle injuries, kissing spine, laminitis, and sore shins.
