I can't believe that you have not used anything to mix your prop with yet. The pain was so bad I was going to trash my supply. I tried different injection sites, including quad and it was terrible. It was hard to walk the next day. You can use safflower oil or grapeseed oil, but you are suppose to boil it. Beware, when I boiled my oil, it filled my house with smoke, smelled like a fast food joint.
