I'm on the second week of my Test 500 cycle. Pinned my right and left quad without incident last week (M/Th), and my right this Monday as well. However, when I went to pin my left quad this morning, I got an extreme pain and was only able to go 3/4 of the way in before it became unbearable and I have to quickly withdraw. No blood came out. I switched out the needle and pinned my right quad without incident. Has this ever happened to anyone before? Also, is it alright that I've pinned my right quad twice in the same week? I hate the thought of having to try again on the left side next week...
