Two of the biggest names in UK sports nutrition. Both make solid protein powders at competitive prices. But which one should you actually buy? Here’s a straight comparison.
The Brands
Myprotein is Europe’s largest sports nutrition brand, part of The Hut Group. Based in Manchester, they ship from UK warehouses and run near-constant promotions. Impact Whey is their flagship product.
Bulk (formerly Bulk Powders) is also a UK brand, founded in Essex. Known for good quality, competitive pricing, and a slightly more premium feel than Myprotein. Strong following among serious gym-goers.
Protein Quality Comparison
| Feature | Myprotein Impact Whey | Bulk Pure Whey Protein |
|---|---|---|
| Protein per serving | 21g | 22g |
| Serving size | 25g | 30g |
| Calories per serving | 103 kcal | 113 kcal |
| Protein ratio | 84% | 73% |
| Type | Whey concentrate | Whey concentrate |
| Flavours | 50+ | 30+ |
Myprotein wins on protein ratio — you get more protein per gram of powder. Bulk’s serving size is larger (30g vs 25g) which inflates the per-serving protein number slightly.
Taste and Mixability
Myprotein: Chocolate Smooth is excellent. Wide flavour range means something for everyone. Mixability is good but not perfect — small clumps without vigorous shaking.
Bulk: Chocolate Milk flavour is genuinely good — slightly creamier than Myprotein’s equivalent. Fewer flavours but the quality of each is more consistent. Mixability is slightly better than Myprotein.
Price Comparison
| Size | Myprotein (sale) | Myprotein (full) | Bulk (sale) | Bulk (full) |
|---|---|---|---|---|
| 1kg | ~£25 | ~£42 | ~£22 | ~£38 |
| 2.5kg | ~£52 | ~£85 | ~£48 | ~£78 |
| 5kg | ~£85 | ~£140 | ~£82 | ~£130 |
At sale price, Bulk is marginally cheaper — but both run frequent sales. The difference per serving is pennies. Price alone shouldn’t decide it.
Other Products
Myprotein has a much larger product range — creatine, vitamins, bars, clothing, specialist supplements. If you want one-stop shopping for all your nutrition needs, Myprotein is more convenient.
Bulk has a more focused range but higher quality across the board. Their creatine, pre-workouts, and vitamins are well-regarded. Better for buyers who care about ingredient quality over price.
Which Should You Buy?
| You should choose… | If… |
|---|---|
| Myprotein | You want the widest flavour selection, one-stop shopping, and are happy to wait for sales |
| Bulk | You want slightly better mixability, more consistent flavour quality, and a cleaner ingredient list |
| Either | You’re primarily driven by price — the difference is minimal at sale prices |
Matt’s Verdict
Both are excellent. For a first purchase, go with Myprotein Chocolate Smooth 1kg — the flavour is hard to beat and the sale price is exceptional. If you’ve tried Myprotein and want to switch things up, Bulk Chocolate Milk is a genuinely good alternative with slightly better mixability.
You can’t go wrong with either. Don’t overthink it — just make sure you’re buying on sale.
