Choosing between MyProtein and Bulk for your supplement needs can feel overwhelming, especially when both brands dominate the UK market with competitive pricing and extensive product ranges. As a fitness professional who’s tested countless supplements, I’ve put together this comprehensive comparison to help you decide which brand deserves your hard-earned money. Whether you’re focused on building muscle, losing fat, or simply maintaining a healthy lifestyle, understanding the differences between these two British supplement giants will ensure you make the right choice for your goals and budget.
Price Comparison: Which Brand Offers Better Value?
When it comes to affordability, both MyProtein and Bulk have built their reputations on offering budget-friendly supplements without compromising quality. MyProtein typically operates on a constant discount model, with promotions running almost daily that can slash prices by 40-60%. Bulk, on the other hand, maintains more consistent pricing with fewer dramatic sales events, positioning themselves as a straightforward, no-nonsense option.
For whey protein specifically, MyProtein’s Impact Whey often retails around £18-25 for 1kg when on sale, whilst Bulk’s Pure Whey Protein sits at approximately £16-22 for the same quantity. However, the actual cost per serving can vary significantly depending on when you purchase. MyProtein’s frequent flash sales mean you can secure exceptional deals if you time your purchase correctly, whereas Bulk’s stable pricing makes budgeting more predictable.
Beyond protein powders, both brands offer competitive pricing across creatine, pre-workouts, vitamins, and other supplements. MyProtein generally has a broader range of products, including an extensive clothing line, whilst Bulk focuses primarily on core supplements and sports nutrition.

Product Quality and Testing Standards
Quality control and third-party testing are crucial factors when selecting a supplement brand, and both MyProtein and Bulk take different approaches to ensuring product integrity. MyProtein holds Informed-Sport certification for many products, meaning they’re tested for banned substances, making them suitable for competitive athletes. They also conduct in-house testing and provide certificates of analysis upon request.
Bulk emphasises transparency with their “Pure” range, which focuses on minimal ingredients and no artificial flavourings or sweeteners. They’ve also achieved ISO 9001 and ISO 22000 certifications, demonstrating commitment to quality management and food safety standards. Both brands manufacture in the UK, which means they’re subject to stringent British and European regulations.
From personal testing experience, both brands deliver on their protein content claims. Independent lab tests conducted by various fitness publications have shown that both MyProtein and Bulk products contain accurate amounts of protein per serving, with minimal discrepancies. Neither brand has faced significant quality scandals, which speaks to their reliability in the UK market.
Taste and Mixability Comparison
Taste is subjective, but it’s often the deciding factor for many supplement users who need to consume protein shakes daily. MyProtein offers over 40 flavours of their Impact Whey, ranging from classic Chocolate Smooth to adventurous options like Birthday Cake and Sticky Toffee Pudding. This variety means there’s something for everyone, though some flavours receive mixed reviews.
Bulk’s flavour range is more conservative, with approximately 15-20 options focusing on traditional favourites. Their flavours tend to be less sweet than MyProtein’s, which some users prefer for a more natural taste profile. The Vanilla, Chocolate, and Strawberry options are consistently well-reviewed for their balanced flavour without being overpowering.
Regarding mixability, both brands perform admirably. MyProtein’s Impact Whey dissolves easily in water or milk with minimal clumping when using a shaker bottle. Bulk’s Pure Whey Protein shows similar characteristics, mixing smoothly without requiring excessive shaking. Neither brand requires a blender for standard mixing, though both can occasionally leave some residue at the bottom of your shaker if not mixed thoroughly.
