Life Pro or Prozis for whey protein: which is better value per kg
The short answer. For whey protein, Life Pro lists 6 products and Prozis another 22. By price per kg, Life Pro’s median is €37.18/kg and Prozis’s is €55.12/kg. The highest scoring across both catalogues is Prozis 100% Whey Prime 1000 g from Prozis, with 66 out of 100 at €30.99/kg. Neither has products at verification level 4: for whey protein the ceiling today is a lab report published by the brand itself, and that is not a certification.
Both stores measured on the same criterion: price per kg and certification verification level. There is no overall winner because there isn’t one: one can win on price and the other on certification, and here you see both separately.
† Some links are affiliate links — they do not change the ranking
Some store links are affiliate links: if you buy through them, this site may earn a commission at no extra cost to you. It changes nothing in the ranking: the score is computed beforehand and without reading those links, and products with no affiliate programme appear exactly the same. How it is calculated.

Life Pro against Prozis, figure by figure
The same numbers for both
| Figure | Life Pro | Prozis |
|---|---|---|
| Products compared | 6 | 22 |
| Median per kg | €37.18/kg | €55.12/kg |
| Cheapest per kg | €34.05/kg | €30.99/kg |

The median is not the price you will pay. It is the midpoint of that store’s catalogue in this category, and it tells you whether a store is dear or cheap overall. For buying, the specific row in the table below is what counts.
What each tub contains
Median dose per serving
Price per kilo does not tell you how much active ingredient is inside the kilo. This table does: for each ingredient, the median dose per serving at each store and how many products reach the dose backed by studies (the same reference this site scores with).
| Ingredient | Life Pro | Prozis |
|---|---|---|
| Whey protein concentrateEvidence-backed dose: from 20 g per serving | —6 of 6 contain it · none publishes the dose | —22 of 22 contain it · none publishes the dose |
The dose is per serving, not per tub. A big tub with a short dose forces you to take two scoops to get the same, and then it lasts half as long: that is why the price per dose in the next section does not match the price per kilo.
Why one is cheaper than the other
Factor by factor, with both stores’ data
Prozis costs 48 % more per kg than Life Pro (€55.12/kg against €37.18/kg, medians of both catalogues). That difference does not come out of nowhere. These are the data that explain it, with each store’s figure alongside: pack size (median).
| Factor | Life Pro | Prozis |
|---|---|---|
| Cost of one effective dosePrice per kg and price per dose point to the same store, so the dose does not erase the label difference: Life Pro is cheaper both ways. | €0.992 | €1.470 |
| Pack size (median)Life Pro sells bigger packs, and a big pack spreads the same tub, the same label and the same shipping over more kilos. Part of the price gap per kg is this and not a discount: comparing one store’s small pack with the other’s large one inflates the gap. | 1.6 kg | 907 g |
| Median rating at the storeBased on 34 reviews at Life Pro and 2 at Prozis. These are the store’s own ratings, which is judge and party: they help spot a product that arrives damaged or tastes awful, not decide which formula is better. | 4.8/5 | 4.6/5 |
None of these factors is an accusation. They are medians of what each store publishes on its pages on the day prices were collected: where a page does not declare a figure, that store does not count in that row instead of counting as a zero. A specific product can contradict its store’s median, and that is what the full table is for. How all of this is calculated.
