I have what I am absolutely sure is legit HCG and it comes in an ampule reading Pregnyl 5000iu. The issue is that theres such a small amount of powder in the amp that it just seems off to me. I've never used HCG before so I don't know what would look right. Does 5000iu's come in a really small amount of powder? About the volume of an eraser on the end of a pencil?
