Personally, I have never done this and I probably wouldn't. I feel it would be redundent. My bro science is that I'd much prefer to combine steroids that are more unique to attack the androgen from different angles, not to mention, you already have 3 unique compounds running through this cycle. I would pick either EQ or 1Test. It sounds like you are running a cutting cycle, and in which case, either one would be fine, but 1 Test cyp does seem to be drier than EQ. Plus, since you have never run it, it might be worth a shot. Also, I feel that 16 wks is a long time to run tren ace. Over time, I feel that my body gets used to a certain drug at a certain dose. I'd much prefer to do something like run NPP for the first 8 wks, and then switch it out for tren in the 2nd 8 wks.
