Okay, now we're talking hypothetically.
Keep in mind, people prefer different steroids for different reasons. If you want to get stupid strong and don't care about sides, drol and tren will do ya. If you want clean gains, you're going to like primo. Some guys bloat on test, others don't. One guy loses his dick using Clomid , someone else gets horny. So again, what someone else uses doesn't matter.
But let's have some fun. Let's take 5 clones who all eat, sleep and train the same and have equal stress levels. They may all look a little different while on, some more full, or vascular or more cut or what have you. But after all is said and done, PCT is complete and you're living with the results. The muscle size, shape, density and definition will be pretty much the same. (Though the damage can very well be more or less severe).
In other words, if Winny builds 5 pounds of muscle with no water and Test builds 5 pounds of muscle with another 10 pounds of water, it's going to appear that they produce different results -- until you drop the water, then it will look exactly the same afterward as long as you keep the same amount of muscle.
