I have sent stuff frozen in deliberate, perfectly-nesting pieces via USPS Priority and have never had a problem. I use styrofoam panels from various packing boxes and assemble them with spray foam to keep the whole thing as tight as possible.

In a large Flat Rate box I can get about 15 pounds of protein...

What is typical transit time via flat rate?
3-5 days, depending on destination.


Generally faster IME and if it is a block and sealed airtight inside the styrofoam it is still frozen at the other end.
