Well if the sides get bad, and you're willing to deal with feeling like shit for 1-2 weeks, here's my advice.
What dose are you running? Something along the lines of 700mg test e per week 350mg tren e per week would work for mass gain. You probably want some cabergoline, prolactrone or pramipexole for prolactin related sides otherwise you might get prolactin induced gyno or your willy won't work. You also need an AI on hand, I recommend aromasin 25mg eod or e3d depending on your sensitivity level. PCT is torem+clomid with triptorelin kickstart after ester clears or I know people on this board recommend clomid+aromasin for 4 weeks.
Since you're running tren, you are going to need a lot of cals to notice a difference at all in weight. It's better at making you recomp than anything.
Personally, I think using tren is kind of a waste for a bulker, especially since it's your first cycle. You might as well just start at 500mg test and ramp it up a few times throughout cycle until you're up to 1g+. that way you don't need to pick up prolactin control drugs and you can just use your AI more heavily if you notice bloat/gyno/etc.
I think heavyiron mentions it in his sticky on how to do a test only ramp up cycle. Something like
1-8: 500mg
8-12: 750mg
12-16: 1000mg
After this cycle, you'll know how you respond to testosterone as a base. If you gain a lot of weight with minimal sides while feeling good, you'll know test is good for you. If you feel like shit, don't gain that much and get bad sides, you'll know low dose testosterone is probably best for you in teh long term.
