I usually like my test at 250-500mg a week with other compounds such as those.
For me less test = less sides.
I'd like to run the deca higher than tren just because tren is really potent as is, something like this,
Test 250-500
Deca 400-600
Tren 200-300
At the higher end of doses you're still running near 1.5 grams of gear a week, I would keep it to 1 gram combined per week max.
