Madison
Heat days are rare in Madison (about 0.2 a year at 95°F+), but the 10-year high reached 97°F, so a heat-wave week is still worth timing around.
Madison
Expect about 28 nights a year at 10°F or colder (10-year low -28°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 $4.50/mg with code vs MyPurePeptide $8.00/mg.
