I was looking at some HCG on powermedica.com and saw that theirs was measured in USP units. What is a USP unit and how does it compare to International Units?

How does it compare to international units?

"In the United States, the reference standards are produced and released under the authority of the United States Pharmacopeia Convention. USP Units and the International Units of potency are usually identical."
