Hell of a combo right there brother! Test Tren Mast is the bread and butter of competitive bodybuilding. Given all the time you’ve had off of cycling, I would suggest starting low. These are strong compounds. Maybe start with 1cc EOD. Then work up to 1.5cc EOD. Then if all is good after 4-5 wks, go to 2cc EOD. Be sure to have an AI in the cycle. I would use adex about 1mg EOD
