Our verdict on each
Diamond CBD
Diamond CBD suits US shoppers who want a sleep and stress line with third-party testing and a long money-back window. A subscription order takes 40% off the price, so a routine buys well; the limit is that orders ship to US only.
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
Diamond CBD
Pros
- Third-party testing is a stated yes, so the lab claim on the products is easy to weigh before buying.
- Subscription orders come in at 40% off, the cheapest way to keep a routine running.
- The money-back window of 100 days gives slow decisions plenty of room.
Cons
- Orders ship to US only, so the 40% subscription saving is worth nothing to anyone outside that market.
- The catalogue is sleep stress and nootropics, a much tighter range than DocMorris, which lists multivitamins, vitamins minerals and omega 3.
- The only certification listed is organic, leaving shoppers who weigh a named testing programme with a thin basis.
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
Diamond CBD
Who it suits
- US shoppers focused on sleep and stress who want third-party testing and a long trial window.
- People happy to order by subscription to take 40% off repeat purchases.
- Shoppers who want a focus product in the same basket, since sleep stress and nootropics covers sleep, stress and nootropics.
Who should look elsewhere
- Anyone who wants a broad catalogue: Diamond CBD covers sleep stress and nootropics, while DocMorris lists multivitamins, vitamins minerals and omega 3.
- Buyers after probiotics, collagen, omega-3 or vitamins and minerals, which Life Extension lists in multivitamins, vitamins minerals and omega 3 and sit outside sleep stress and nootropics.
- Shoppers living outside US, where the brand does not ship.
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
Diamond CBD
What does the subscription discount do to the price?+
Subscription orders are marked at 40% off, and that saving attaches to the subscription rather than to a single buy. Pair it with the 100 days money-back window and a cautious trial is easier to justify. Serving cost still moves with the size of the format you pick, so compare the listed serving figures before settling.
Is there a long return window if a product misses the mark?+
The money-back guarantee runs 100 days, long enough to judge a sleep or stress formula over repeated use rather than a single night. Requests go to the same team, reachable on email, chat and phone. Together they make a slow decision low risk, as long as you keep the terms attached to your order.
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.
