I have been using 300mg TestE from same source every week for 2 years. A few weeks ago the injection almost knocked me out it hurt so bad. I thought I just hit something wrong. Next week same thing. I contacted source and was told High BA content and new bottle sent out. First injection out of new bottle was BRUTAL and pain stayed for over a week. Can sterile oil be mixed in to cut out BA content? Is this smart? I have a hard time spending more money on Test that I am unable to use. Any help would be great!
