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.
Transparent Labs
Pros
- Protein per serving of 28 g ranks 10 of 43 brands in our protein powders data
- Third-party tested products give buyers independent label checks before buying
- Category spread covers whey protein, plant protein, creatine, pre-workout, electrolytes, protein bars and mass gainer through whey protein, plant protein and creatine
Cons
- Entry price of $64.99 ranks 57 of 66 brands in our price data, so it is not the cheapest way in
- Serving cost of $1.33 on the multivitamin line sits above the €0 site median once a daily item is included
- Support runs on email and help centre only, with no phone line for questions about dosing or orders
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.
Transparent Labs
Who it suits
- Lifters chasing a high protein figure per serving rather than the lowest serving price
- Vegan shoppers, since the multivitamin line lists vegan in vegan and the protein range carries organic and vegan in organic and vegan
- Consumers in the US, GB, AU and CA who want one brand for protein, creatine and pre-workout
Who should look elsewhere
- Budget buyers comparing only entry price, where cheaper brands in our price ranking come first
- HUM Nutrition shoppers who only want plant protein and creatine and prefer a narrower range
- Anyone who needs meal replacement shakes, a category Body Attack lists and this range omits

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.
Transparent Labs
How much does Transparent Labs cost to start?+
The range starts at $64.99, which ranks 57 of 66 brands in our price data. Ordering on a subscription reduces each delivery by 10%. Buyers who only want one tub pay the entry figure, while regular buyers pay less per order.
How much protein is in each serving?+
A serving carries 28 g of protein, which puts the range at 10 of 43 brands in our protein powders comparison. That is the strongest argument for the price, since cheaper options often give less protein per scoop.
