I would wait to run the tren for the last 8 wks, right into the show. I'd also consider stacking it with masteron p. This is the "bread and butter" of competition cycling. There is no need for the hardeners until then. No need for tren at 12 or 16 wks out. Its a very toxic drug and you want to stay as healthy and sensitve to the gear as possible, So start with less and build into the show. Remember that this is all about the diet. If you are not reaelly lean, the gear is not going to matter. So get the diet right and then the gear will just add to the look. At 16 wks out, I would consider starting fat burners but no need for the hardeners
