I started using your basic beginner cycle Test-E for 12 weeks 500 mg Every week (250 Monday morning and 250 Thursday night.) And I've been injecting in my shoulder (switching shoulders), because that is where my friend showed me. It has been 2 and 1/2 weeks and I have developed some kind of lump right above my tricep. It's about a quarter size and it is tender to the touch. And its about 2 inches from where I inject. Any ideas? Should I see a Dr.? Or is it just some random occurrence that has absolutely nothing to do with my cycle? Any input will be greatly appreciated.
