I got it once from shooting tren only in the syringe. Steril, double filtered .08 and .02, heat treated 250 for 45min and still got it. So it's not from dirty gear. I aspirated, no blood(I've never hit a BV in my glute). So it's not from hitting a vein. It hinda felt like a breathed in a ton of dust. It went away after a little while. The whole time on tren though, I loose my breath a lot faster. I really noticed it during sex. When I'm really going at it, I get so short i have to stop and catch my breath, almost like asthma.
Amazing drug, but due to the sides, can only cycle it for short periods of time. I don't get the slightest night sweats, only slightly, for a short period when I 1st took it.
