How We Rank Deals
ProteinDeals is built around transparent comparison metrics rather than brand preference.
Primary ranking signals
The comparison table lets users sort and filter products by price, price per 100g, protein per 100g, price per serving, calories and stock status where that data is available.
Price per 100g is one of the most important baseline metrics because it normalises products with different pack sizes.
Retailer and affiliate influence
Affiliate relationships do not decide which products appear as the best value in the comparison table. The ranking is driven by product and price data.
Sponsored or affiliate outbound links may earn ProteinDeals a commission, but users should still compare the final checkout price at the retailer before purchasing.
Data freshness
Protein prices and stock status can change quickly. ProteinDeals is designed around regularly refreshed data, but retailer pages remain the final source of truth at checkout.
If a retailer changes a price, removes stock or changes a discount code after our latest update, the checkout page may differ from the comparison table.
