Here is our Dit Da Jow, a formula that we ourselves (and other Martial Artists) have been using for many years for conditioning (Iron Palm, Iron Forearm & Shin etc) and also for small injuries like bruising and soreness that occur after contact training. We don't have a "1000 year old formula created by Shaoling Monks in a cave" story but we can say this formula was given directly to us by an Iron palm Master.
More information to come when the Jow is available.
