Frequently Asked Questions

Common questions about ProteinDeals

ProteinDeals compares tracked US retailer products by cost per 25g of protein. Pack size and protein content both count, so a lower tub price does not automatically mean better value. Filter whey, isolate and vegan protein powders to compare their protein cost, calories and total pack prices.
