Impact Whey pairs good protein density with strong value and unusually useful third-party programmes for banned substances and label protein content. The score applies to the reviewed regional product family, not every collaboration flavour or local formulation.
Score breakdown
| Area | Finding | Score |
|---|---|---|
| Formulation | Complete whey; up to 23 g protein | 22 / 25 |
| Transparency | Variation disclosed, but local labels differ | 18 / 20 |
| Laboratory verification | Informed Choice and Informed Protein | 18 / 20 |
| Safety | Banned-substance programme and allergen disclosure | 14 / 15 |
| Company reliability | Large established operator; evidence remains product-led | 8 / 10 |
| Value | Strong mainstream value when bought at normal discount | 8 / 10 |
Formula and ingredients
Myprotein reports up to 23 g protein and 114 calories per serving, with values varying by flavour. The base product is whey concentrate rather than an isolate. That is not a defect for buyers who tolerate lactose and do not need the leanest possible macro profile.
Laboratory and certification trail
Myprotein lists Impact Whey under Informed Choice and Informed Protein. The programmes answer different questions: banned-substance screening and verification of labelled protein content. Neither should be stretched into a claim that every possible contaminant has been publicly assayed.
Company accountability
The strongest accountability signal is the named third-party programme and regional product entries. Sales volume, customer-review count and brand visibility do not enter the score.

Impact Whey was selected as GQ’s favourite protein powder. We treat this as editorial recognition for the product experience—not laboratory evidence.

This is the clearest value-led option in the current audited field when discounts are genuine and the local label matches the certified product. Buyers should compare the normal selling price, not an inflated crossed-out reference price.
Limits and update trigger
No taste test or commissioned assay by ShreddedAF. Formula, serving size and certification must be checked for the exact country and flavour.
