This is my second cycle I have done in the last year. The problem I am having is the pain and sorness that comes with the shots. I atlernate between shoulders and and then butt cheeks, but I get so sore and it "lumps" up a bit around the injection site. I am using sustanon 300 and doing 300 mg a week. Then I am going to switch to Testenanthate. So what shoud I do
