I used the pens for my loading dose (4 shots then 2 shots 2 weeks later). For the first 4 shots, I stopped at my doctor's office on the way to work. The nurse gave the first one and I gave the other 3 (all in my abdomen). I had no side effects, and drove to work. For the shots 2 weeks later, I injected them in my thigh and found them to sting more than in the abdomen. It hurts for just seconds.
This month, I'm going to try the syringes. I didn't have a problem with the pens, but the whole big plastic gizmo seemed like a lot of waste, so I'll help the environment and use the syringe.
Btw, I'm from Michigan too!
