Having a pretty bad problem with test flu, although it seems to be pretty inconsistent. When I pin my quads I get fairly debilitating pip and swelling (no redness though) for a few days, accompanied by chills and fever about a day or two after pinning, and lasts about two days before subsiding. Ibuprofen deals pretty well with symptoms, but it's definitely becoming a huge game killer.
For whatever reason, this hasn't been the case for pinning my delts. I'm not sure whats going on here, as this is only my 2nd cycle, I had none of these symptoms with my first.
I'm definitely chalking this up to probably bad injection techniques for me....have pinned a couple of other places including my right leg and nothing happened. I have an aggravated muscle or something that keeps swelling up. I'll just stay off that quad for awhile.
