I have suffered with cramping all my life, and always at the critical moment!!!! I have tried many different remedies, with no success, I literally had resigned to having this issue for ever, till I found CrampFix spray in the supermarket and tried it, I was skeptical and over the next few rides used it before the ride and suffered no cramping, still a little skeptical I ordered the shots, and today completed a 120KM ride with a small Quad cramp with 10ks to go that disappeared with a shot!!!!!! I have been using the shots before and during the ride when I feel that tingle in my legs, I am convinced!!!! and am highly recommending CrampFix, a product i have waited to long to discover!!! thank you.
