Injection Issues/Questions

[apocolypse]

Had a bit of a wierd issue with my gear, and looking for some advice. I've done multiple glute injections before with no problem, yet did one yesterday and having some issues. It was pretty sore yesterday, and now today the area is discolored (redish), fairly swollen, and somewhat itchy. On one hand I was thinking I just messed up the injection, but I've also had to switch from Mexican to Chinese gear and this is my first injection with the new gear. Some searches of old threads showed other people at least getting sore from it, so I'm wondering if it sounded like it was more the gear, or me messing up the injection. I know we aren't to post UGL names, so I left it out, but some members may know what one I'm talking about. And in case it's relevant, the gear was just Test E, a little less than one and a half cc's of it. Thanks for any help you all may have.
