Our verdict on each
KoRo
KoRo suits adults inside Germany who want a broad supplement range at a low cost per serving rather than a plan or a subscription. The money back window of 14 days and the DE reach keep the commitment small, though products are not third-party tested and the listed certification is organic.
WeightWorld
WeightWorld suits lifters who want a cheap creatine tub and a wider sports-nutrition order in one place, with prices from €24.99 and a serving cost of €0.28. It is a broad shop rather than a specialist, so check the subscription rate before you commit.

Pros and cons
KoRo
Pros
- A serving cost of €0.01 makes daily use inexpensive, and the entry price of €19.50 keeps a first order small.
- Range spans vitamins minerals, omega 3 and probiotics, wider than the vitamins and minerals focus at ProSolution Plus and TestRX.
- Products suit vegan and vegetarian diets, and the listed certification is organic.
Cons
- Third-party tested is no, and the listed certification is organic, so an independent potency check sits outside what is stated.
- Price from ranks 44 of 157 brands, so the entry price is not the cheapest in the comparison.
- The range covers DE only, which is narrower than a multi-line pharmacy such as DocMorris.
WeightWorld
Pros
- Serving cost of €0.28 puts WeightWorld at 1 of 46 brands compared on price per serving
- Entry price of €24.99 keeps the first order modest while the subscription rate of 10% trims repeat buys
- Range covers creatine, pre workout and electrolytes, wider than Nuun at electrolytes and CON-CR?T Creatine at creatine, electrolytes and pre workout
Cons
- Entry price of €24.99 places WeightWorld at 22 of 66 brands compared, well away from its per-serving value
- Creatine monohydrate comes in 1 flavour, so there is little choice for anyone who wants a flavoured powder
- Sells in Ireland, GB and FR, and that catalogue is narrower than Body Attack at whey protein, plant protein and creatine
Who each suits
KoRo
Who it suits
- Adults in DE who order one-off supplements rather than a plan
- Vegan and vegetarian shoppers, since the diets listed are vegan and vegetarian
- People who weigh cost per serving above all, given the rank of 1
Who should look elsewhere
- Shoppers who require third-party tested products, since third-party tested is no
- Anyone outside DE, where the range does not reach
- Buyers chasing sleep, stress and nootropic lines, listed for DocMorris in multivitamins, vitamins minerals and omega 3 but not part of vitamins minerals, omega 3 and probiotics
WeightWorld
Who it suits
- Lifters buying creatine monohydrate on a tight per-serving budget
- People in Ireland, GB and FR who want one shop for creatine, pre-workout and electrolytes
- Vegetarians and vegans shopping vegan, vegetarian and keto products with gmp and vegan
Who should look elsewhere
- Buyers who want the widest sports-nutrition catalogue, since Body Attack carries whey protein, plant protein and creatine
- People who want electrolyte tablets from a single-purpose line, as Nuun carries electrolytes
- Shoppers who prefer a smaller creatine and pre-workout line, since CON-CR?T Creatine lists creatine, electrolytes and pre workout

Questions about each
KoRo
How much does KoRo cost?+
Prices start at €19.50, and the cost per serving is €0.01. The first figure matters for a single purchase, the second for anyone taking a product every day. The price shown is the one you pay, so no second bill arrives later.
Is KoRo cheaper than rival supplement brands?+
It depends which measure you use. On price from, KoRo ranks 44 of 157 brands, so the entry price sits mid-table. On price per serving it ranks 1 of 121 brands, the stronger result of the two for a daily user.
WeightWorld
How much does WeightWorld creatine cost per serving?+
Creatine monohydrate is priced at €24.99 to start, and each serving works out at €0.28. That per-serving figure is what puts the brand at position 1 of 46 brands compared in the creatine and pre-workout group, so the serving cost matters more here than the tub size.
Is the first order the cheapest price?+
Not really. On price from, WeightWorld ranks 22 of 66 brands compared, so the entry figure is ordinary for the group. The value sits in the running cost of €0.28 a serving rather than in the opening price, so weigh the two before ordering.
