Your look is largely due to diet. Yes, gear will effect your puffiness, but you can still look pretty darn good on what are traditionally considered "bulking" drugs. Just keep that in mind as you move forward. As for lactation and prolactin based gyno, it isn't SUPER common that guys I work with are sensitive to prolactin, but it does happen. Maybe 1 out of 10 has a problem. Changes in sex drive are most common. Guys that actually lactate are fewer, but once again, it does happen. Using caber at .5mg 2x wk is the route I would employ. Caber will take care of issues quikly. It wouldn't hurt to have some on hand. As far as type of tren to use, I would only ever suggest Ace for a first run. It is easy to manage and control. If an issue came up, you can simply skip a couple of shots and you will find relief. With Tren E, it can take wks.
But look, all of this said, For lean gains, I would not use Deca or Tren. I would use EQ. EQ is my favorite compound for muscle gains. The side effects are low. The gains are slower than something like deca, but I find the muscle to be "real", less fluid. EQ makes me feel good. Strength and stamina is good. The key is to use it a little longer. I would run it for 16 wks for muscle gains. It takes a little while to really kick in because of the long ester, but as long as you are eating to grow, you can do well.
So if you wanted to use Tbol, here is how I would use it, based off of your experience
1-16
Test 500mg
EQ 4-500mg
adex .5mg 2x wk, more only if needed for estrogen related sides
1-6
Tbol 50mg ED
