Is this your first cycle? If so, it's plenty. I'm extreamly pro for low dose cycles.
I'd suggest running it for atleast 10 weeks though. Eight weeks is too short imo. No need to run the dbol yet. Save it for your next cycle.
1st cycle: Test 250mg weekly for 10 weeks.
I've personally seen people run this, and they have gained on average around 10-15#s.
