IMO there is no point in going 400mg in the first 5 weeks then 500mg then next five. Go 400 or 500 or even 450mg all the way.
I would also run the EQ for weeks 1-8 and again at one dose, no tapering up.
Week 1-10: Test E 500mg
Week 1-8: EQ 400mg
Week 1-4: Dbol 20mg
Also what is your cycle experience? If this is your first I think 3 compounds is too much, I would go for just Test E @ 400-500mg for 10 weeks
