† 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.
Nothing is claimed about the formula in this category. None of these stores publishes how much active ingredient each dose carries, so the score comes from the price per kg and the verification level, and nobody appears here as well or badly dosed: we do not have the data and we do not make it up.

Questions about mass gainer
Answered with the data on this page
- Which mass gainer should you buy?
- Zumub Heavy Gainer 4Kg (2x 2Kg) from Zumub, with 81 points out of 100 at €7.50/kg. The mark is 35 % price against the cheapest in the category, 35 % verifiable quality (certification, purity and additives), 20 % the category's own requirements and 10 % the buyers' rating at the store, and no commercial deal moves the ranking.
- Which is the cheapest mass gainer?
- Zumub Heavy Gainer 4Kg (2x 2Kg) from Zumub, at €7.50/kg (4000 g pack for 29,99 €). It sits at verification level 1 out of 4. Cheap is not the same as well scored: price is 35 % of the mark and most of the rest is how verifiable its certification is.
- How much does a kilo of mass gainer cost?
- Between €7.50/kg and €469.01/kg across the 12 stores compared, with a median of €18.98/kg. That is the price per kg, not per pack: two tubs at the same price can cost twice as much as each other depending on what is inside.
- What certification should mass gainer have?
- Of the 96 products compared, 0 reach level 4 (the certification is backed by a third party: either we checked it with the body that issues it, or the product carries in its name a trademark that requires a third party behind it, such as Creapure or IFOS) and 0 reach level 3 (a lab report published by the brand itself). The remaining 96 stop at a certification claimed on the product page, or none at all. Only level 4 is checked against whoever issues the certification.
