IP INJ.=PAIN!!!!!!! If you can get anything else, don't go with IP the shit is too painful and the products are too hit and miss. So what if it's cheap, if the stuff does nothing for you or you have so much pain you cannot continue well there goes your cheap stuff! You get what you pay for! If you decide to go with IP I promise you will regret it! There is QV gear that you can get at very good prices and it is good stuff.
