an AI will work to stop most of the issues of bloat revolving around Test but will do little for Tren and Deca which is why when you run Test with Tren or Deca you need both an AI and Cabergoline
Use arimidex .5mg ed or eod depending on what your cycle is. I used to be called fat face while on test until I got adex. That stuff took the bloat away after about 4-6days. Love it!
