can i add some tren to my current cycle?

right now i'm in my 8th week of 500mg cyp and 500 mg eq. i'm going for 12 weeks, and waiting 3 weeks after last injection to start pct, so i basically have 8 weeks left. my gains have pretty much stopped now, so i was wondering if i could throw in Tren At maybe 75mg eod?? i would throw it in for the last 6 weeks.
