Label note: The net weight on the labels are required by Long Island Weights & Measures. It doesn’t reflect calories or macros. Your nutrition info comes from the recipe and the measured scoops of each ingredient, not how heavy the container is. Since foods can hold a little more or less water, the weight may change slightly, but the calories and macros stay the same.

Must be refrigerated. Can freeze up to 3 months.

Shipping costs $19.99 or $29.99 depending on your location and special packaging. Some states require 2-day shipping. If ground shipping isn’t shown, it may be due to your location or timing. Orders process within 24-48 hours before shipping.

A color-coded U.S. map shows shipping schedules by state for a business, with zones for 1-day, 2-day, and ground delivery. A chart lists order cutoff times and expected ship dates. Text explains shipping methods and processing times.
