Hello Everyone. I am in my 10th week of Denkall UltraGan EQ. Last week I injected 2 cc's into my rear delt, and I had typical soreness for a couple of hours (nothing out of the ordinary). After about the 4th day I developed a bruise that extended from the injection site all the way down into the upper head of my Tricep. There is no soreness, it just looks like someone smashed a baseball bat on the back of my arm. Anybody ever had anything like that happen to them? What causes it, how do I prevent it?
