Myprotein vs Bulk Whey Protein: UK Budget Showdown
Quick Verdict
Both are excellent budget whey proteins from UK brands. Myprotein wins on flavour variety and regular sales. Bulk wins on protein per serving and everyday pricing. The differences are marginal — pick whichever you prefer the taste of.
Nutritional Comparison (per serving)
| Metric | Myprotein Impact Whey | Bulk Pure Whey |
|---|---|---|
| Serving size | 25g | 30g |
| Protein | 21g | 22g |
| Calories | 103 kcal | 110 kcal |
| Fat | 1.9g | 1.8g |
| Carbs | 1.0g | 2.5g |
| Protein % | 84% | 73% |
| Type | Concentrate | Concentrate |
Myprotein’s smaller serving size gives it a higher protein percentage, but Bulk delivers slightly more total protein per scoop. In practice, the difference is negligible.
Price Comparison

|---|---|---|
| Full price (1kg) | ~£20 | ~£18 |
| Sale price (1kg) | ~£13–15 | ~£15–16 |
| Cost per serving (full) | ~£0.60 | ~£0.54 |
| Cost per serving (sale) | ~£0.39–0.45 | ~£0.45–0.48 |
| Subscribe & save | No | Yes (5% off) |
Myprotein has more aggressive sales (sometimes 50–60% off), making it cheaper during promotions. Bulk’s everyday pricing is more consistent and they offer a subscribe-and-save discount.
Taste and Mixability
Myprotein: 60+ flavours ranging from Chocolate Smooth and Salted Caramel (excellent) to more adventurous options like Blueberry Cheesecake and Sticky Toffee Pudding (hit or miss). Mixes well in a shaker with minor clumping. Some flavours are overly sweet.
Bulk: Around 15 flavours with Chocolate, Vanilla, and Strawberry being the most popular. Slightly thicker consistency and arguably better base flavour. Less variety but the core flavours are all solid. Mixes similarly to Myprotein.
Packaging and Experience
Myprotein ships in resealable pouches that work well. Bulk also uses pouches with a slightly more premium feel. Both brands offer 500g, 1kg, 2.5kg, and 5kg options. Bulk’s website is cleaner and easier to navigate; Myprotein’s site is cluttered with constant pop-ups and upsells.
Who Each Brand Suits
Choose Myprotein if you:
- Love trying different flavours
- Time your purchases around sales for the best UK price
- Want the widest product range (bars, snacks, clothing, etc.)
- Don’t mind a busier shopping experience
Choose Bulk if you:
- Prefer consistent, fair pricing without waiting for sales
- Want a simpler, no-nonsense buying experience
- Like subscribe-and-save convenience
- Are happy with a smaller but reliable flavour range
Final Recommendation
You genuinely cannot go wrong with either. If you’re patient and buy Myprotein during sales, it’s the cheapest quality whey in the UK. If you want reliable pricing and a cleaner experience, Bulk is the better everyday choice. Both deliver solid protein at budget prices.
