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.
Myprotein
Pros
- Price per serving of £1.10 puts it at 10 of 46 brands on cost per scoop, the strongest ranking in the set.
- The catalogue covers whey protein, plant protein and creatine, so creatine, pre-workout, electrolytes and meal replacement sit in the same basket as protein.
- The Impact Whey range carries 40 flavours, which cuts the odds of a repeat order going to waste.
Cons
- Entry price of £32.99 ranks 44 of 66 brands, so the headline figure is not the cheapest on the market.
- The range is certified to Informed Sport only, with no organic or GMP certification listed, while 24.8% of brands compared carry organic.
- Protein per serving of 22 to 23 g sits just under the 24 median across protein powder brands.
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.
Myprotein
Who it suits
- Lifters and everyday gym users who want a low cost per scoop and many flavours to choose from
- Vegan, vegetarian and gluten-free shoppers who want protein and creatine in the same order
- Anyone based in one of the GB, AL and AD listed delivery markets
Who should look elsewhere
- HUM Nutrition shoppers who only want plant protein and creatine in a small range
- Myvitamins shoppers looking for a vitamins and minerals range alongside performance products
- Body Attack shoppers who want the lowest entry price on a whey tub

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.
Myprotein
How much does Myprotein protein cost per serving?+
The Impact Whey range works out at £1.10 per serving, and each serving carries 22 to 23 g of protein. On cost per scoop that places Myprotein at 10 of 46 brands compared, which is the figure to watch if you order regularly.
Is the entry price on Myprotein the cheapest?+
The range starts at £32.99, and on that headline figure Myprotein ranks 44 of 66 brands compared. Cheaper entry prices exist in this category, so the first order is not where Myprotein leads. Its strength is the per serving cost that follows.
