I'd drop the eq, and run it in another cycle. Test, deca and drol will be a crazy stack and you WILL grow. Eq is not beneficial to this cycle IMHO because it has a reputation of not providing extra gains, and it's one more compound for your poor drol-riddled liver to take care of...the hepatoxicity of drol is second to none, so I'd be cautious about over-doing it. When your liver takes a beating, you won't think future, you'll think about NOW
Now IMO for dosage, deca should be minimum 12 weeks, and test should be run 2 weeks longer than deca, 4 weeks past deca would be better. Last 2 weeks of 4 week extension would be really good to run a very small dose like 250mg weekly.. More of a test replacement than to gain muscle. Your balls are going to take a beating as well. Take hcg at 250iu eod (or twice a week at least) to stim those balls. Also will help with restarting your natty test after being completely shut down for so long. Deca works fast for shutting you down.
I'd stick with adex for ai and have letro on hand in case you develope gyno. With deca and test it can still happen.
I'd also consider some milk thistle for liver cleaning effects, but I've heard it shouldn't be taken on cycle because it fights the gear. I doubt it though.
THIS IS MY OPINION... I'm not a doctor or anyone special... Just joe

correct me if I'm wrong with this information
