bro, you need to do ALOT more reading and research before you start.
modifying their inherrent characteristics with ancillaries aside, var is usually used for cutting, dbol for bulking.
that said, you could probably use var + dbol in a bulking cycle, but since they're both 17aa, watch your liver enzymes and use rALA and milk thistle for protection.
p.s. the var will temporarily KILL your HDL, and if you're going to eat more animal fat on your bulking diet thats not a good place to be...
if you're going to use the var+dbol in a cutting cycle, be sure to use arimidex/anastrozole/liquidex etc to keep the dbol estrogen down.
