I have to agree with the consensus on test flu. Note, I have had test flu on dr. prescribed test from the pharmacy so UG etc. does not matter. I expect since you are on CYP that it took a few injections to build up sufficiently to affect your system. You can read up in the stickies on half lifes and esters. You did the right thing on going to the doctor on the off chance you had a real infection, far better to be safe than sorry.
