Back up your quote.
Retractile muscle tissue grows on progressive overload, its the basic adaptation of the protein muscle tissue. &guy, for all practical purposes, means necessarilly stronger, this is true for hormonized athletes, though the training regime may vary because of augmented protein accretion and synthesis.
Saying that there is something as bigger and not stronger, or stronger but not bigger makes no sense. You will never be big if you dont squat big, you will never squat big if you are not big.
Oh, and dont even worry about starting a discussion of this, citation wars and "I have a friend" examples dont work on the internet.
Also, steroids are the reason why people dont know how to strength train, they do much of the work, as you may already know, a natural trainee will grow less overtime (not a new trainee) than a hormonized individual who doesnt actually strength train because of the sheer anabolic property of aas.
