Good evening, I have a question regarding a symptom I feel since starting up gear. On the last 3 pins I do, I have noticed that after pinning 1-cc of Test 400, I get the "punies" or the equivalent to a fever/flu like symptoms. I had to swap out a brand, one that I had not used for years. It also gets very sore. Could it be because of the oil used by a specific brand?
