How prices work

Where the prices come from

Mjerica reads each product's price from the stores' own websites. These stores are compared; select one to open its website.

How often they are updated

Prices are updated weekly. They were last updated on 15.10.2026.

What the numbers mean

€/kg is the price divided by the package weight, so a 2.5 kg bag and a 1 kg bag can be compared directly. €/serving is the price divided by the number of servings, where the store states it. Capsules and gummies are compared per piece.

The summary boxes

Each category page opens with a few boxes. Cheapest per kg also shows the price per 30 g of powder (whey) or per 5 g of powder (creatine): a comparison portion so prices are easier to picture, not dosing advice.

The creatine box, Cheapest pure monohydrate per kg, only names a product whose store page gives an ingredient list of creatine monohydrate alone; we checked those lists by hand and note the date. Blends (for example with dextrose), other forms and products we could not check are still listed, just not named in that box. Small labels such as Isolate or Blend come from the product name unless they say the ingredients were checked.

Protein per € is estimated from the product type (concentrate, isolate…), not read from each label. Lowest price is simply the cheapest pack to try, whatever its size; it is not a value-for-money ranking.
