java script help

Can someone help me figure out how to hack/crack this java to give me 500 Stamina its a counter that counts every 1 hour and gives you 50 Stamina and the max Stamina is 500 I was wondering if theres a way to type something in my address bar that will get me 500 Stamina straight away instead of waiting the time? I have looked in the script and pulled this out ? and i am hoping someone can help me out

Thanks Lupus
