Premarin is the same hormone found in humans, and works just as well as the human stuff. At least until fairly recently, there were also hormone products being made from the urine of post-menopausal nuns. But horse urine is cheaper and easier to collect.
Are you a doctor? A researcher? Where’d you get that “fact?”
You are wrong there sir, it is not the same as found in humans. My body never made a single drop of horse urine.
