Read the full verdict
PER4M is very widely stocked in the UK, which means it goes on offer often. On formulation it is worth understanding what you are buying: this is a four-source milk blend that includes skim milk powder, which is roughly half lactose and is the main reason the sugar sits at 10g per 100g. If you are choosing on protein per pound that may not matter. If you are lactose sensitive, it will.
Where to buy PER4M Nutrition Whey Protein
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.

Ingredients and formulation
- 01Whey protein concentrate
- 02Whey protein isolate
- 03Milk protein concentrate
- 04Skim milk powder
This is a four-source milk blend rather than a straight whey. Skim milk powder is the fourth protein source and is also where much of the 10g of sugar per 100g comes from, since skim milk powder is roughly half lactose. PER4M does not publish the ratio.

More than 40 flavours, the widest range in this batch and heavily dessert-led. An unflavoured version exists.
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.
PER4M does not appear in either database, nor in the SupplementLabTest archive.

Frequently asked questions
How much protein is in PER4M Whey Protein?
21g in a 30g scoop, about 70g per 100g. That is normal for a concentrate-led blend and roughly 20g per 100g below a true isolate.
Why does PER4M Whey have 10g of sugar per 100g?
The blend includes skim milk powder, which is roughly half lactose. Lactose is a sugar, so it shows up in the sugars row. On a 30g serving that is about 3g.
Is PER4M Whey Protein third-party tested?
We found no evidence of Informed Sport or Informed Choice certification. That is not the same as saying it is untested, but we could not verify any third-party programme.
