I believe X-MASS is non-methylated and doesn't aromatize easily. PRO-TEST is methylated though, right? I've never used cissus-drol for an AI but from what I've read I'm not entirely sure it is sufficient by itself. If I were you, I'd by some research chemical called nolvadex (30/20/20/10), get yourself some sustain alpha (5-7 pumps for weeks 1-4 or 5 of PCT), activate xtreme is good for weeks 2-6. That'd be my plan but I'm real cautious about restarting my HPTA and I always run a stringent PCT.
I'm obligated to say - you should have set up PCT before starting the cycle. You shouldn't be picking it up the week you want to start - but I'm sure you know that.
