"Horse Needle". The needle in question is 23 and is the same size used to pull blood. My children are even brave and don't scream with it at the pediatrician. It does create a moment or two prick however. 1x a week, not a big deal. Take it and forget about it. And again, the efficacy will be superior. Whether the superiority will be very clinically meaningful or not, I don't know.
This said, 23 is not confirmed yet, and 21 is still a concern if a 21 will be required. I think a 23 can move the product with swift sales, but if it turns out to be a 21, then I'll talk "horse needle" and that will be a major issue for sales.
a 21 1x a week or a daily pen needle. That would be a much more difficult sell for the 21.
