HSN or Prozis for whey protein: which is better value per kg
The short answer. For whey protein, HSN lists 6 products and Prozis another 22. By price per kg, HSN’s median is €30.00/kg and Prozis’s is €55.12/kg. The highest scoring across both catalogues is HSN Raw Series 100% Whey protein concentrate 2Kg from HSN, with 81 out of 100 at €30.00/kg. The cheapest per kg is HSN Sport Series Evobasic whey 2Kg from HSN, at €21.54/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.

HSN against Prozis, figure by figure
The same numbers for both
| Figure | HSN | Prozis |

| Products compared | 6 | 22 |
| Median per kg | €30.00/kg | €55.12/kg |
| Cheapest per kg | €21.54/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 | HSN | Prozis |
|---|---|---|
| Whey protein concentrateEvidence-backed dose: from 20 g per serving | 29.9 g6 of 6 contain it · 6 reach 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 84 % more per kg than HSN (€55.12/kg against €30.00/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), different brands in the catalogue, products with declared additives, with a published lab report (level 3 or 4).
| Factor | HSN | 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: HSN is cheaper both ways. | €0.811 | €1.470 |
| Pack size (median)HSN 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. | 2 kg | 907 g |
| Different brands in the catalogueProzis mostly sells one brand, Prozis: 100 % of its catalogue in this category. HSN spreads its own across 2 brands. A store selling its own brand skips the manufacturer’s margin and can cut the price without touching the formula; a reseller pays that margin and passes it on, and in exchange carries brands the other does not sell. | 2 (67 % HSN Sport Series) | 1 (100 % Prozis) |
| Products with declared additivesWhat the pages of both declare: colourings, artificial sweeteners. An additive is not fraud, but it takes up grams that are not active ingredient and is cheaper than the active ingredient: where more additive is declared, the price per kg drops without the product being better. | 67 % | 0 % |
| With a published lab report (level 3 or 4)HSN publishes lab reports on more product pages. Testing a batch in a lab costs money and is passed on in the price: part of what you pay extra is the check that the tub contains what the label says. It is the only part of the premium you can read in a PDF. | 4 of 6 | 0 of 22 |
| Median rating at the storeBased on 5,368 reviews at HSN 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. | 4.7/5 | 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.
