So as much as I love EQ, I'd 100% hand it to Deca in terms of lean tissue accrual. The reasons to consider EQ are its higher safety profile, lesser sides, and the ability to use it as a pseudo-AI. Just know that you're gonna need significantly more EQ mg/mg, and it will be less potent. Personally, I'd forgo test altogether and run a Deca/EQ split, then finish off with Dbol at the end. Deca/EQ/Dbol is a beautiful and classic cycle, and most guys can run Deca without test (in fact, some prefer it). Of course, its up to individual response on that one. Now if Deca is causing you significant sides, its likely due to something progestogenic, so I'd be checking my bloods to see what may be causing the sides you mentioned. Really, I'd think over if Deca is worth it for me with those sides, or if there is something I can do to eliminate them. Also in terms of Test/EQ, you gotta dial in the raito that's right for you. I've never had issues with higher EQ, but some do tend to have low E2 sides from it (due to EQ preforming competitive aromatase and tying up the aromatase enzyme, which lessens the conversion rate). Hope that helps!
