I am really just looking for a clearer answer to my last cycle pip issues. I have researched all the previous threads pertaining to this subject. Hours upon hours. Here's how it went: the first 5 weeks of my cycle I was using sustanon no issues at all. 500mg a week split up in 2 doses @ 250mg/cc. After I used up my sustanon that I had I went over to testosterone cypionate. It is dosed the same. On my first injection in my right glute everything was smooth. This was a AM injection. No pain after injecting at all. The next morning it was swollen, red, and warm. (Never burning hot) The next morning it looked like I had a sunburn on my right a$$ cheek. Late PM on the 4th day I was worried about infection so I started taking antibiotics. I then told myself I was going to stop the cycle. Late PM on the 5th day it looked like the swelling was still apparent and fluid was accumulated down my quad. Pain is unreal without taking 800mg Advil. Redness was not spreading any further. It took day 7-8 for things to go back to normal. Now, since I was antibiotics for a few more days I decided to try a new bottle of the same stuff to see if it was just a bad bottle. I even boiled some water and put the new vial in it for 10 mins. (Up to the oil line) Maybe the gear crashed and this may have helped reconstitute. Anyway did an injection 1cc into my left glute and the same reaction happened. Advil to function. Is this normal to get gear like this here and there? Has anyone endure pain for up to 10 days after each injection for and entire (or half) cycle?
