HSN or PromoFarma for BCAA: which is better value per kg

The short answer. For BCAA, HSN lists 10 products and PromoFarma another 13. By price per kg, HSN’s median is €24.20/kg and PromoFarma’s is €61.72/kg. The highest scoring across both catalogues is HSN Raw Series BCAA's instantáneo 2:1:1 2.0 1Kg from HSN, with 81 out of 100 at €20.00/kg. Neither has products at verification level 4: for BCAA 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.

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).

Ingredients and dose per serving at HSN and PromoFarma, for BCAA
IngredientHSNPromoFarma
BCAAEvidence-backed dose: from 5 g per serving5 g10 of 10 contain it · 10 reach the dose—13 of 13 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 155 % more per kg than HSN (€61.72/kg against €24.20/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: different brands in the catalogue, products with declared additives.

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.€0.121€0.309
Different brands in the catalogueHSN mostly sells one brand, HSN Raw Series: 60 % of its catalogue in this category. PromoFarma spreads its own across 8 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 (60 % HSN Raw Series)8 (31 % BEST PROTEIN)
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.40 %0 %
Median rating at the storeBased on 5,275 reviews at HSN and 1 at PromoFarma. 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.4.7/54/5

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.
