Our verdict on each
MaximumSlim
MaximumSlim suits US buyers who want a broad supplement range at a low entry price and a per serving cost that repeats cheaply. The brand scores 9.1 overall, with a starting price of $19.99 and a 60 day money back window on the Original Green Coffee line.
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
MaximumSlim
Pros
- Entry price of $19.99 ranks 37 of 157 brands, so a single pack is an easy outlay.
- A subscription takes 20% off later orders, lowering the renewal side of the bill for regular buyers.
- The range covers multivitamins, vitamins minerals and greens, far broader than ProSolution Plus, whose catalogue is vitamins minerals.
Cons
- Per serving ranking of 85 of 121 is weaker than the entry price ranking, so daily use costs more than the pack price implies.
- Support runs on email and help centre, with no phone or chat line in the listed options, so quick answers depend on written replies.
- Product types stop at multivitamins, vitamins minerals and greens, while DocMorris lists multivitamins, vitamins minerals and omega 3, so sleep, stress and collagen buyers get nothing from this range.
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
MaximumSlim
Who it suits
- US buyers who want multivitamins, vitamins minerals and greens ordered from a single supplier
- Daily supplement users who judge cost by $1.67 a serving rather than the pack price
- Shoppers who want a 60 day money back window before committing to a greens coffee order
Who should look elsewhere
- Buyers after sleep, stress or collagen lines: DocMorris lists multivitamins, vitamins minerals and omega 3, none of which the MaximumSlim range covers.
- Shoppers who want a short, single category catalogue: ProSolution Plus stays on vitamins minerals and keeps the range narrow.
- People who only want vitamins and minerals listed: TestRX covers vitamins minerals and nothing wider, which is simpler to shop.
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
MaximumSlim
How much does MaximumSlim cost to start with?+
The Original Green Coffee pack is listed at $19.99, and each serving works out at $1.67. Buyers sampling a single product can judge the outlay from the pack price, while daily users should read the per serving figure, since that is the line that repeats.
What does subscribing change on the bill?+
A subscription takes 20% off later orders, so the entry price and the renewal price are separate figures. Shoppers who will reorder can plan around the lower number, and shoppers who expect to stop after a short run of orders should not count on the saving.
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.
