i have used deca and eq, and love them both it really depends on ur goals, deca gives nice swell and fullness to muscle a and makes ur joints feel better and usally ran for about 10-12 weeks, eq gives hard look to body and good lean gains and more viens and most run for about 14+ weeks as it takes a while to kick in, some people wont use deca cause there scared of limp dick or big shut down or sensitive to progesterone gyno, eq its easier recover from and doesnt really have sexual sides, but some people dont use eq cause of anxiety , i personally dont get anxiety from eq i get it more from deca, test/deca/eq with an oral is the ultimate stack , get a bit from both worlds, dont knock either one till u try it
peace
