Both of these products are as pure as the driven snow! The test is on the left, it is bonafide genuine Test Enanthate and it (if you can see and look close) looks like a brick of Grits, like you eat, that is hard as wax. Very white. The Deca (which is serious grade A Deca) is on the right and is slighty off white, little brown but not nearly as brown as a chickens egg but has that slight chicken egg tint but the consistancy of it is solid, there is no bubbly looking stuff in it like grits or like the test looks.
