Detroit
Heat days are rare in Detroit (about 0.6 a year at 95°F+), but the 10-year high reached 100°F, so a heat-wave week is still worth timing around.
Ann Arbor
Expect about 14 nights a year at 10°F or colder (10-year low -17°F). Dry powder is fine frozen, but bacteriostatic water can freeze and crack its vial, and a frozen vial opened straight away pulls condensation onto the cake. Let sealed vials sit at room temperature for 20–30 minutes before opening.
Climate: ERA5 reanalysis via Open-Meteo, daily 2 m temperature, 2016–2025.
Per mg: Purgo $3.75/mg with code vs Idun Peptides $4.50/mg.

Detroit has Wayne State University; Ann Arbor has University of Michigan; Grand Rapids has Van Andel Institute. Labs at these institutions typically buy through institutional suppliers; independent and small-company researchers in Midwest are the buyers this guide is for.
