I've heard of the infamous Test Flu and thinkin that it's hittin me right now and hard. Been runnin 500mg of Test E for the last 3+ weeks now and last inj was yest, boy oh boy...my shoulder was in pain after that and the next morn(this morn) I felt like absolute crap. I'm under the impression this is more or less "normal" and I should be g2g in a day or so..What's up with this though?? I mean why does this happen EXACTLY??? Shouldn't the bodies immune system be increased with an abundance of Test???
