Canadian insulin

Question for those of you who have bought insulin from Canada and had it shipped to the US. I’ve been looking into it quite a bit (thanks for everyone who recommended marks marine pharmacy!) so we can order my SOs insulin which currently costs us over 800 dollars a month here.

Is it safer/ better to order from a pharmacy such as marks or can I have it shipped by a person? One of my good friends lives in Canada and is willing to ship it to me but I’m wondering which route is less likely to sit in customs or possibly be confiscated.
