test, deca and eq is a good stack for a good bulk, i personally enjoy it, as stated below your better of choosing either deca or tren, not both, also depending on your opinions on pinning, test prop kicker would be healthier than the dbol, after ten cycles you would know all this, id do something like-

test e- 1-20- 750mgs
test p- 1-6- 150 eod
deca- 1-16- 500mgs
eq- 1-18- 800mgs

obviously you need good solid support ancillaries, caber, ai of choice and good pct, you will need something for your blood pressure, its going to get real high unless your onto it straight away, you will need blood work done at least twice on cycle, once before and once or twice after cycle and pct, donate blood week 12 and 18, avoid stimulants! including high dose caffeine! keep yourself very hydrated, eq is notorious for headaches, a sign of dehydration, also a sign of high rbc, i would start ai from 1st day off week two low dose and adjust and ramp up as needed, with your caber, shouldn't be needed until beyond week eight, but thats where blood work and knowing your body comes into play, keep your vitamin and mineral count high, and eat for a bulk ( what your goal is ) and you will literally look like a different man at the other end of this cycle, the deca will beef you up the the eq will kick and dry up the puff and harden you and almost condition you at the same time, you will enjoy the vascularity about week 12( and the pump) just another tip, have antibiotics on hand in ample amounts, its a lot off pinning, and infection at the sites are a big possibility, good luck, and im here if you have any questions or need guidance.

12 weeks isnt't really long enough for EQ to live up to its potential. 16 weeks minimum, preferably 18-20. Get some bold cyp if you are gonna run 12 weeks only. A low dose of deca could still be beneficial. 600mg bold cyp, 400mg test e, 200mg deca and 50mg anadrol 2 weeks on 2 weeks off throughout the cycle would be my choice.
