Size and growth deca ****s all over eq.. Eq will add polish to an already lean physique or a physique just entering lean mode.. Adds some details.. But no weight persay on the scale.. The mass added is very small from eq and hardly noticeable.. Deca is king for mass and size.. I really doubt yiull see much prog effects from deca.. Its very independent of each person.. But most wont face those sides unless dosing over 700mg..
