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.
British GQ Best Protein Powders UK 2025
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.
Decision before price
Impact Whey Protein is best considered for value-focused buyers who want a conventional whey with named external testing programmes. That is a defined use case, not a universal “best protein” claim. The main reason to skip it is flavour and region variation make a single universal macro and price claim unreliable.
The score measures the strength of the public product record across formula, transparency, verification, safety, company accountability and value. It does not establish that the reader needs powder, will prefer the taste or should pay the local price.
How to compare the tub in front of you
The reviewed identity is global listing excluding the USA, Canada and India; vanilla packshot shown. Check the exact local label. Flavours can change protein percentage, sweeteners, allergens, inclusions and certification status. A matching brand name or similar package in another country is not enough; compare the live label, serving and exact certifier entry.
Price should be converted into cost per useful protein serving. Then compare protein source, grams delivered, total energy, added creatine or botanicals, allergen information and product-level verification. A cheaper tub can be poor value if the serving is small or the label is unclear. A premium tub can also be poor value when the extra cost buys flavour marketing rather than traceability or fit.
What the score cannot prove
ShreddedAF did not purchase the retail unit, control chain of custody, taste the flavour or commission a laboratory assay. Certification can strengthen confidence in the exact product and programme scope; it cannot prove superior hypertrophy, digestion or safety for every person. Company statements establish the marketed specification, not independent confirmation of every lot.
Buying checklist
- Confirm country, flavour, serving size and protein grams on the live label.
- Check whether the exact product—not merely the brand—appears in a current directory.
- Compare price per useful protein serving and the food alternative.
- Account for allergens, sweeteners, thickeners and added actives.
- Do not buy when ordinary food already covers the intake target conveniently.
The 60-second decision
If ordinary meals already cover the daily protein target conveniently, another tub has no job. If a gap exists, calculate how many useful servings the package supplies and whether the flavour, digestion and format make consistent use realistic. The best purchase is the least complicated verified product that solves the actual gap at a sensible cost.
A higher score can reduce uncertainty about the product record; it cannot guarantee taste, tolerance or additional muscle. Training stimulus, total protein, energy intake and consistency remain upstream of the brand choice.
Update triggers
Re-score if the formula, serving, certification, warnings, ownership, manufacturing disclosure or material evidence changes. Awards, retail placement, customer-review volume and affiliate economics never trigger a higher score.
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.
