Verified U.S. offers ranked by cost per 25 g of protein.

What qualifies?

Only approved sizes and flavors with verified label nutrition and fresh U.S. offers qualify. Shipping and tax are excluded. Some links may earn FitFrek a commission; that does not affect the ranking.

Fresh rankings are temporarily unavailable

We do not substitute stale or estimated prices. The ranking returns after the next successful data check.

How we calculate value

Cost per 25 g = item price ÷ (servings × protein grams per serving) × 25.

We compare eligible offers for each approved variant, choose the best variant for each product family, then rank those families. The two price modes are calculated together from the same data.

Full eligibility rules

Conventional protein powders only. We exclude bars, ready-to-drink shakes, mass gainers, collagen-only products, protein coffee, meal replacements and closeout stock. First-order offers, subscriptions, memberships and multi-tub promotions do not reduce the ranking price.

Prices must have a successful check within 72 hours. Exact label nutrition is reviewed at least every 180 days and after relevant changes. A missing or ambiguous value is withheld, never estimated.
