Tren cyp, huh? Never heard of it lol. But I'm honestly not a fan of tren in long ester form. I much prefer acetate and no I wouldn't mix them. Much better to have full control over how much tren is in your system at a time with tren ace IMO.
Eq is great for cutting AND bulking depending on how you eat and train. Same goes for every steroid no that I'm thinking about it! So the compounds are less of a factor than your diet and training in terms of whether you're bulking or cutting. Eq has my vote over deca any day of the week, though, so I like Eq for bulking.
I would honestly do a nice long 16 week bulking cycle with just test and eq, and leave the tren for your next cut as adding tren will likely increase your calorie demand so high that it'll turn your cycle into more of a recomp. It's very difficult to bulk on tren.
I would also add proviron to help free up more test and help buffer estrogen. You'll still wanna run an AI but you'll be able to run less of your AI (let's say about .25 eod) and with 50-75mg of proviron you'll be sitting pretty. It will also act like a minor kick starter to get things moving in the first few weeks without causing a ton of bloating and water retention like a traditional kick start oral would cause...That is a personal pref so take or leave it, but I feel like it's added a lot to my regimen so feel free to try it out as it will keep you dryer and harder though out cycle.
So that's my take on it. Just test and eq with proviron through out the entire cycle. Leave the tren for a cutting cycle.
