I have been on cycle for the past 3 years 750mg week of test cyp from the same manufacturer, never had coughing problems except when i hit a vein usually on my deltoid, ive done tren before also with no cough.
Recently i switched over to test enth and right after the injection i cough and end up vomiting, i thought it was odd, i did it again the next week with the same problem, i think it has to do something with the switch , ive done enth before no problems. it only happens with that particular new bottle, i hit prop and no issues
I always aspirate.
