As ultramarathon runners ourselves, we created Cramp Killer to help us meet our own racing goals.
We’re excited to support you in yours! Check out below and we will have your bottle shipped to you ASAP.
Just received my first bottle of Cramp Killer and it’s truly amazing. Stupid cramps have truly been cramping my style and I have a trail half next month that had me very concerned. Spray, rub, no cramp.
This oil has saved my legs a few times but this last race I am amazed with it!! Yesterday I was not able to bend my left leg at all without wanting to vomit and cry because of the pain. Today I am slow and still in some pain but I can bend my knee! Anyone with pains should try this… #MagnesiumOilSprayIsTheBomb
