HSN or PromoFarma for glutamine: which is better value per kg
The short answer. For glutamine, HSN lists 7 products and PromoFarma another 15. By price per kg, HSN’s median is €24.73/kg and PromoFarma’s is €84.93/kg. The highest scoring across both catalogues is HSN Raw Series L-glutamina en polvo 1Kg from HSN, with 76 out of 100 at €18.02/kg. Neither has products at verification level 4: for glutamine 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 PromoFarma, figure by figure
The same numbers for both

| Median per kg | €24.73/kg | €84.93/kg |
| Cheapest per kg | €18.02/kg | €56.78/kg |

| Level 3 (the brand’s own lab report) | 0 of 7 | 0 of 15 |
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 | PromoFarma |
|---|---|---|
| GlutamineEvidence-backed dose: from 5 g per serving | 5 g7 of 7 contain it · 7 reach the dose | —15 of 15 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
PromoFarma costs 243 % more per kg than HSN (€84.93/kg against €24.73/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.
| Factor | HSN | PromoFarma |
|---|---|---|
| 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. | €0.124 | €0.425 |
| 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. | 500 g | 300 g |
| Different brands in the catalogueHSN mostly sells one brand, HSN Raw Series: 86 % of its catalogue in this category. PromoFarma spreads its own across 15 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 (86 % HSN Raw Series) | 15 (7 % Mega) |
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.
