Both are different types of AAS, EQ stands for equipoise which is a steroid that is supposed to increase appitite, improved vascularity and hardness, And Propinate is a short ester steroid most use to kickstart a cycle because it kicks in faster than a longer ester such as cyp. or enanthate. Prop must be shot at least every other day tho, and Eq only should be shot twice a week. Hope that helps a little
