Well the question we are trying to answer Bee is if there is a safe drug available that will increase your circulation so you don't have to freeze while winter camping. While this topic certainly invites lots of potential joke opportunities it is a serious subject matter.Viagra has been shown to have the abilty to increase peripheal circulation. The abilty to bring blood to the extremities not only serves as a performance enhancer by delivering more blood to the muscles but should also help keep head,hands and feet warmer.It certainly causes facial and torso flushing which is obvious vaso dilation.There are many athletes using it for the ability to incresae periperal circulation. Just throwing out a thought that has been discussed a lot in terms of a viable use of viagra.
