Tren is a great compound, but for the most part it hurts you diet. Not mine, but in most people it does. Sure others will post their thoughts as well.
If i was going to recommend a pure bulking cycle it would go like this:
Test E 600mgs EW/12 weeks
Deca 500mgs EW/11 weeks
D-Bol 40mgs weeks 1-4....Would be ok to do this 9-12 as well. Make sure there's an increase in quality cals going into PCT and during.
