Neither of these compounds are “wet”. In anabolic slang, wet is defined as water retention under the skin. Typically from estrogen via aromatization (test, M14ad, 4andro, dbol etc), but also with compounds that can raise estro that don’t aromatize (deca/NPP, LMG, prodienelone).
What people mean is DMZ & Msten both tend to hold a lot of glycogen in the muscle - still water weight that gets shed post cycle, but having the water IN the muscle instead of ON it makes a world of aesthetic difference. Hope that helps clarify some. They will put water weight on you like most orals but they are decidedly dry by nature. LMG is wet.
