Well, it finally happened. I've been on doctor trt for about 5 years (I'm guessing, I'm old) so jabbing once a week, and twice if I'm throwing something else in, for a while now. Right now I'm doing 100 test c and approximately 160 Tren e twice a week. Never had a single problem until last week. About 3/4 of the pin in and I have a metallic taste in my mouth and feel a little light headed. I've read about it, so I know it's coming. Then the coughing hits as I'm just finishing. Holy crap it's a bit scary, hard to catch your breath. Fortunately, it's not as bad as some I've heard about, and passes in a couple minutes. I always aspirate, and didn't see blood, so I guess I nicked a vein or something. Anyone else experience this? If so, how bad was it?
