Bests & Worsts Reviews from Amazon

The stuff works for my cramps better than anything else. I am a long distance runner and I use is just as a cramp is starting whether on the drive home from a race, or that night in bed. Update June 17, 2016 I have never updated one of my reviews before, but I am making an exception here. I have been using this product for two months now and it is fantastic. I have used it during and after a long run and in the middle of the night. It has taken away my leg cramps every time. Once at mile 22 of a run my hands were cramping up, so I asked a kind man on the porch of a house I was passing to pull the bottle from my hydration pack pocket and open it for me. He did, keeping his lit cigarette lit the whole time. Worked for the hands as well. I have also been refilling these little bottles with pickle juice from jars of pickles from the grocery store. I think it works just as well, but for long races, I will certainly use new unopened bottles. I don't want to take any chances there. Update: July 30, 2017 I continue to use this product with wonderful results. It immediately takes away muscle cramps in my calfs. It has yet to fail me with cramps in my legs or even my feet. The only time I did not get relief was when I had cramps in my fingers after a very long and hard race. For that I squeezed a soft ball about two inches in diameter, which got me through the drive home. I have stopped refilling my bottles, but I think it is still a viable option.
