34 products ranked. Updated 2026-05-19.
Overview
It's a genuine coin flip between these two protein bar heavyweights, but on the numbers, Muscle Nation edges it with a single standout bar. Their HIGH PROTEIN BAR - Choc Honeycomb takes the top spot in our analysis, delivering 30.1g of protein per serve. While the average Protein Score across both brands is nearly identical, Muscle Nation secures the win with the highest-scoring single bar in this showdown. That said, BSc's lineup shouldn't be overlooked, especially if you want the absolute most protein for your calories. Their High Protein Bar range dominates on density, with the Salted Caramel flavour packing a huge 52.7g of protein per 100g. BSc also wins on lowest sugar, so if you're prioritising macro purity, their bars are the smarter pick when you spot them at Coles and Woolworths.
The verdict
On average Protein Score, this matchup between BSc and Muscle Nation is a coin flip. BSc's High Protein Bar range consistently delivers a bigger protein density, hitting 52.7g of protein per 100g in their Salted Caramel bar, and also wins on lowest sugar. But it's Muscle Nation that nabs the highest individual Protein Score in our analysis with its HIGH PROTEIN BAR - Choc Honeycomb. While the numbers give Muscle Nation's top scorer the win, its list of eight additives is a red flag, so we'd skip it. For a cleaner bar from the same brand, the Muscle Nation Crisp Protein Bar Choc Brownie is the smarter pick. If your priority is the absolute biggest protein hit with a more reasonable ingredient list, the BSc High Protein Bar Choc Fudge delivers a massive 48g of protein per serve and keeps its additives to a more modest five.
Rankings
- #1. Muscle Nation Crisp Protein Bar Choc Brownie - Protein Score 9.5/10 · Clean Score 7.4/10 · 20.4g/serve
Protein Score 9.5/10. Muscle Nation Crisp Protein Bar Choc Brownie leads this comparison with 20.4g of protein per serve, 34.1g of protein per 100g and just 3g of sugar per 100g. Its Clean Score is 7.4 with 5 additives, so it is still a formulated bar, but it gives Muscle Nation the strongest all-round slot in this match-up.

- #2. BSc Soft Protein Bar Banana Chocolate - Protein Score 9.4/10 · Clean Score 6.6/10 · 16.2g/serve
Protein Score 9.4/10. BSc Soft Protein Bar Banana Chocolate takes second place with 16.2g of protein per serve and 29.4g of protein per 100g. It keeps sugar to 3.9g per 100g, but the Clean Score of 6.6 reflects a longer ingredient list with 6 additives. It is a solid BSc option that delivers a softer, baked texture for shoppers who prefer a confectionery-style bar, though it is not as clean as the Muscle Nation leader on this list.

Editorial deep dive
It's a genuine head-to-head on the protein bar shelf between BSc and Muscle Nation. Both are major players you'll find stocked at Coles and Woolworths, and with 34 bars between them in our analysis, they cover every texture and flavour profile you could ask. Looking at the average Protein Score across their entire lineups, the difference is negligible. It's a coin flip, so the right choice comes down to what you prioritise in a bar. If your only goal is the maximum protein hit, BSc takes the round. Their High Protein Bar range is seriously dense, with the Salted Caramel flavour packing 52.7g of protein per 100g. Muscle Nation's best effort in this specific contest, the HIGH PROTEIN BAR in Cookies & Cream flavour, lands at a still-43.9g of protein per 100g. For pure protein density, BSc has the edge. However, the numbers on the front of the box don't tell the full story. Our top-ranked bar in this matchup is the Muscle Nation HIGH PROTEIN BAR - Choc Honeycomb, but with eight additives on its ingredient list, we say skip it. The same goes for the #3 ranked BSc High Protein Bar Cookies & Cream, which contains six additives. When the top of the list is this cluttered, we look for the cleaner pick. The highest-ranked bar that avoids our skip warning is the Muscle Nation Crisp Protein Bar Choc Brownie, which keeps the additive count to five. The sugar numbers also draw a clear line. BSc is the winner here, with its High Protein Bar Cookies & Cream containing just 1.2g of sugar per 100g. Muscle Nation's lowest is 2.3g of sugar per 100g in their HIGH PROTEIN BAR - Choc Honeycomb. Both brands lean heavily on sugar alcohols like maltitol to keep sugar low, so if you have a sensitive stomach, you might want to test one before committing to a full box. So, who wins? Neither brand, outright. They're effectively tied. Your best move depends on your priorities. If you want the highest possible protein content and aren't fussed by a longer ingredient list, the BSc High Protein Bar range delivers. But if you want a more balanced bar, we'd point you to the Muscle Nation Crisp Protein Bar Choc Brownie. It offers a solid protein hit with a cleaner profile than the top-ranked bars from either brand.

- The BSc High Protein Bar range is the clear winner for low sugar content. The Cookies & Cream flavour leads the pack with just 1.2g of sugar per 100g, closely followed by the White Choc Raspberry flavour at 1.6g of sugar per 100g. These figures are low for the category.

The BSc High Protein Bar Salted Caramel flavour is the most protein-dense bar we scored in this guide, with 52.7g of protein per 100g. Other flavours like Choc Fudge and Cookies & Cream are right behind it with 52.2g and 52.4g of protein per 100g, respectively.

- What's the difference between Muscle Nation High Protein and Custard bars?
- The difference comes down to a trade-off between protein and sugar. Muscle Nation's HIGH PROTEIN BAR range is built for macros, with the Choc Honeycomb flavour providing 43g of protein per 100g and just 2.3g of sugar per 100g. In contrast, the Custard Protein Bar range offers a softer, filled texture but sacrifices protein and adds sugar to get there. For example, their Custard Protein Bar in Choc Fudge Brownie has only 28.9g of protein per 100g while containing 4.9g of sugar per 100g. If your priority is a higher Protein Score and better macros, choose the HIGH PROTEIN BAR range every time.
- How does ProteinScore rate BSc and Muscle Nation protein bars?
- Our Protein Score provides a single number to compare protein bars, but it's not just a measure of raw protein. The score is calculated using an algorithm that rewards high protein density (grams of protein per 100g) while penalising things that detract from a lean protein source, like excess sugar, sodium, and total calories. This is why a bar with slightly less protein might score higher if it's significantly lower in sugar or calories. We also calculate a separate Clean Score, which evaluates the use of artificial sweeteners, colours, and the overall length of the ingredients list.
- Are BSc and Muscle Nation protein bars gluten-free?
- Based on the ingredient labels we screen, most protein bars from BSc and the High Protein range from Muscle Nation do not list gluten as a primary allergen. However, some specific Muscle Nation bars, particularly in the Custard Protein Bar range, explicitly state gluten in the allergen information. Because formulations can change and cross-contamination is always a possibility in manufacturing, it's crucial to check the packaging yourself before purchasing. If you have coeliac disease or a serious gluten sensitivity, always rely on the on-pack statement for the most accurate information.
