Just wanted to shout out hi. Wanted to let you know that I have taken Trenbalone off and on for about 3 years. Just did an injection on my upper thigh and IMMEDIATELY had one of the worse Tren coughs of my life. It went on about 3 minutes of almost solid hard, gut wrenching coughing and shortness of breath. I came close to calling 911 but it was slowly subsiding. I have had it before but never to this extent. I am pretty sure I hit a vein as well which led to it's severity. Be careful with the injection site.
