How the numbers stack up against the price
£1.05 buys 25g of protein here, which makes it the 8th cheapest of the 24 powders we have reviewed, behind Protein Works Whey Protein 360 - PLATINUM Innovation at £1.03, and 5p under the median.
It is also Informed Choice certified, and isolate leads the blend. The two things to weigh against that are the salt, at 1.4g per 100g the highest here, and saturated fat at 3.7g per 100g, which is roughly double most of its competition.

Cheapest in-stock listing at a partner retailer, for packs of 400g and over. MyProtein Clear Whey Protein, Protein Works Vegan Protein 360 - GOLD Innovation, Protein Works Vegan Protein 360 - PLATINUM Innovation, Protein Works Vegan Pea Protein - BLACK Innovation, Protein Works 100% Micellar Casein - BLACK Innovation, Protein Works Diet Whey Protein Isolate - BLACK Innovation, Protein Works Clear Diet Whey Protein - GOLD Innovation have no partner listing in stock, so they carry no figure.
Isolate is listed first, then hydrolysate, then concentrate, which is an unusually strong ordering for this price. USN does not publish the ratio. The formula also carries inulin, which is where the 7.4g of fibre per 100g comes from, and Tolerase L, a pH-stable lactase enzyme.
What the label gets right, and wrong
Strengths
- Isolate is first on the ingredient list, ahead of hydrolysate and concentrate
- Added Tolerase L lactase enzyme, the only product in this batch with one
- Informed Choice certified, which is a real third-party programme
- Inulin gives it 7.4g of fibre per 100g, unusual in a whey product
Watch-outs
- Salt at 1.4g per 100g is the highest in this batch
- Saturated fat at 3.7g per 100g is roughly double most competitors
- Informed Choice is per production run, not per batch like Informed Sport
- The allergen statement warns of soy traces even though the ingredient list specifies sunflower lecithin
Where to buy it
Ordered by cost per 25g of protein, because pack sizes and protein densities differ enough that a headline price on its own does not tell you which is better value.

Price history
What a scoop actually contains
Taken from the manufacturer’s published label. Source.
USN states 24g of protein in a 34g scoop, which resolves to about 70.6g per 100g and matches the per-100g panel reproduced by UK retailers. One retailer still shows a 26g figure, which appears to be a superseded formula. We use USN’s own number.

The allergen statement nonetheless warns of possible traces of soya protein from soy lecithin, which contradicts the ingredient list. Do not treat this product as soy free.

Third-party testing
Certification is per programme and often per flavour or per batch, so a badge on one product does not carry across a brand’s whole range.
Informed Choice tests a sample per production run. That is a weaker guarantee than Informed Sport, which tests every batch. We found no Informed Sport listing for this product.

Taste and what buyers report
Quoted and linked, so you can read the full thread.
“USN or Gold Standard are the two I have found to be best.”
What the maker does not publish
- USN does not disclose the country of manufacture for the UK stock.
- USN publishes its per-flavour nutrition as images we could not read, so the per-100g panel here comes from a retailer reproduction rather than USN directly.
- Buyer reports do not converge on a best or worst flavour for this product.
Questions buyers ask
The things people search for about USN Blue Lab Whey, answered from the label and the live partner prices rather than from the brand’s own copy.
How much protein is in USN Blue Lab Whey?
24g of protein in a 34g scoop, about 70g per 100g. One UK retailer still lists 26g, which appears to be an older formula.
Is USN Blue Lab Whey good for lactose intolerance?
It contains Tolerase L, a pH-stable lactase enzyme intended to help break down lactose, and isolate leads the blend, which is naturally lower in lactose than concentrate. That is a better starting point than most whey blends, but it is not a lactose-free product.
Is USN Blue Lab Whey Informed Sport certified?
It is Informed Choice certified, not Informed Sport. Informed Choice tests a sample per production run; Informed Sport tests every batch. If you compete in a tested federation, that distinction matters.
