I am doing my first cycle and I choose to inject into my deltoid. I am using a 23 gauge 1.5" needle. Everything is sterilized before injecting, a new needle everytime. I am doing 1 ML twice a week. Alternating deltoids, taking around 5-7 seconds to inject. Right after injection my delt is sore as ****!!! It seems to last about the whole day, then goes back to normal. I wondered if this is semi-normal? I know I could use other sites such as my thigh/glute, but for some reason the deltoid just seems right for me. Anyone have any info on why this is happening? Or is this common?
