Musashi is one of the most familiar sports nutrition names in Australia and New Zealand. Walk into a supermarket or chemist and you will usually see at least three of its tubs side by side. They look similar, they cost about the same, and the front labels all promise protein. The differences are on the back.
This guide walks through the three Musashi powders most people choose between, how to read their labels, and how to work out which one suits you. If you want the bigger picture on every protein type, start with our guide to choosing the right type of protein powder.
The three Musashi powders at a glance
| 100% Whey | High Protein | Plant Protein | |
|---|---|---|---|
| Protein source | Whey concentrate and whey isolate | Whey concentrate, whey isolate and milk proteins | Pea, brown rice and chia |
| Protein per serve (as listed) | About 24 g | About 30 g per 45 g serve | About 22 g per 32 g serve |
| Dairy | Yes | Yes | No |
| Best fit | Everyday shakes, value per tub | Bigger serve, more protein per scoop | Dairy-free or plant-based eaters |
Always check the panel on the tub you buy. Recipes and serve sizes change between flavours and batches, and prices change often.
Why protein matters, in plain terms
Protein is needed for building and repairing body tissue, including muscle. Most adults can get enough from food alone. A powder is a convenience, not a requirement. It is useful when you are busy, when your appetite is small, or when you want an easy protein serve after training.
Research reviews of resistance training (including the International Society of Sports Nutrition position stand on protein and exercise, Jäger and colleagues, 2017) find that total daily protein matters more than the brand or the exact timing. So the right powder is the one you will actually use, that agrees with your stomach, and that fits your budget.
If you are over 50 and building strength, our guide to starting resistance training safely explains why the training itself matters as much as the protein.
Musashi 100% Whey: the everyday choice
This is a blend of whey protein concentrate (WPC) and whey protein isolate (WPI). Concentrate keeps a little more lactose and fat. Isolate is filtered further, so it is higher in protein and lower in lactose.
What to look for on the label:
- Protein per 100 g. This is the fairest way to compare tubs, because serve sizes differ. Whey blends usually sit somewhere between 70 g and 80 g of protein per 100 g.
- Lactose. A WPC and WPI blend still contains some lactose. If dairy upsets you, read our lactose-free protein powder guide first.
- Testing. The Amazon listing says this product is batch tested under Sport-Informed. That matters most for people in tested sport, who need to know a product has been screened for banned substances.
Who it suits: people who digest dairy well and want a simple, good-value daily shake.

Available on Amazon Australia. Check the label and current price before you buy.
Musashi High Protein: more protein per scoop
This one combines whey concentrate, whey isolate and milk proteins. Milk proteins include casein, which digests more slowly than whey. The listed serve is larger (45 g) and gives about 30 g of protein.
What to look for on the label:
- Serve size versus protein. 30 g of protein in a 45 g scoop works out to roughly two-thirds protein. That is good, but compare it per 100 g with the other tubs rather than per scoop.
- Added fibre. The listing says it contains inulin, a type of fibre. Some people find inulin causes wind or bloating, so start with a half serve if you are sensitive.
- Sweeteners. Check the ingredients list for the sweetener used if you prefer to avoid any.
Who it suits: people who want one bigger protein serve, for example as part of a quick breakfast.
Musashi High Protein Powder, Vanilla
Available on Amazon Australia. Check the label and current price before you buy.
Musashi Plant Protein: the dairy-free option
This is a blend of pea, brown rice and chia protein. Blending plant proteins is common because each source is low in a different amino acid, and mixing them gives a more complete profile.
Can plant protein keep up with whey? Two small human trials suggest it can for many people who train. In a 12-week trial of young men doing resistance training, pea protein and whey led to similar gains in muscle thickness (Babault and colleagues, 2015, Journal of the International Society of Sports Nutrition). In an 8-week high-intensity training trial, pea and whey groups showed similar results (Banaszek and colleagues, 2019, Sports). Both trials were small and short, so treat them as encouraging rather than final.
What to look for on the label:
- Protein per 100 g. About 22 g in a 32 g serve is close to 70 per cent protein, which is solid for a plant blend.
- Texture. Plant powders are often thicker and earthier. Blending with milk alternatives, banana or oats helps.
- Allergens. Check the label if you have allergies, and check where it was made if cross-contact matters to you.
Who it suits: vegans, vegetarians, and anyone who avoids dairy.

How to work out the real cost
The tub price does not tell you much. Work out the cost per 100 g of protein instead:
- Find the protein per 100 g on the nutrition panel.
- Multiply it by the tub size in kilograms and by 10. That gives you the grams of protein in the whole tub.
- Divide the price by the grams of protein, then multiply by 100.
Example: a 2 kg tub with 75 g of protein per 100 g holds 1,500 g of protein. At $77.49, that is about $5.17 per 100 g of protein. Do the same for each tub you are considering and the best value becomes obvious.
Quick checklist before you buy
- Is it dairy or plant based, and does that suit you?
- What is the protein per 100 g, not just per scoop?
- Does the ingredients list include anything you avoid (lactose, inulin, a particular sweetener, allergens)?
- Is it batch tested, if you compete in tested sport?
- What is the cost per 100 g of protein?
- Where will you store it? Our guide on whether protein powder expires covers storage.
Common mistakes
- Comparing per scoop instead of per 100 g. Bigger scoops look better on the front label.
- Using powder to replace meals you enjoy. Food first, powder to fill gaps.
- Starting with a full serve of a new powder. Start with half to see how your stomach handles it.
- Assuming more protein is always better. Your daily total matters more than any single shake.
Fitting protein into your day
Protein powders are a convenience, not a requirement. For many people, the first place to look is everyday food, and a powder can help fill a gap when meals are busy. This section is general information and not personal dietary advice.
How much protein do adults need?
Australia and New Zealand’s Nutrient Reference Values suggest around 0.75 grams of protein per kilogram of body weight a day for women and 0.84 grams for men aged 19 to 70, with somewhat higher figures for older adults. Needs vary with age, activity and health, and many people already meet them through food. A doctor or accredited practising dietitian can advise what is right for you, particularly if you have a kidney condition or another health concern.
Food sources worth remembering
Eggs, dairy foods, fish, poultry, lean meat, legumes, tofu, nuts and seeds all provide protein. Spreading it across meals, instead of eating most of it in one sitting, suits many people’s routines.
Reading the label
Check the serving size, the grams of protein per serve, the ingredient list and any allergen statements, such as milk or soy. Compare products using cost per gram of protein rather than the price of the tub alone, as shown in the cost section above. Because supplements are not all tested to the same standard, some people prefer products that state independent testing, particularly athletes who compete under anti-doping rules.
Frequently asked questions
Is Musashi protein good for older adults?
Protein powder can be an easy way to add protein if your appetite is small. Older adults often benefit from spreading protein across meals. If you have kidney disease or another medical condition, talk to your doctor or an Accredited Practising Dietitian before adding a powder.
Which Musashi protein is lowest in lactose?
Of these three, the plant protein contains no dairy. The whey products contain some lactose.
Can I bake with it?
Yes, many people add protein powder to pancakes, muffins or oats. Whey can make baking a little dry, so add extra liquid.
Is clear protein better?
It is different, not better. Clear whey isolates are lighter and juice-like. Our clear protein powder guide explains when it is worth it.
The bottom line
All three Musashi powders give you a solid serve of protein. Choose 100% Whey for everyday value, High Protein for a bigger scoop, and Plant Protein if you avoid dairy. Compare them per 100 g of protein, check the ingredients for anything that disagrees with you, and remember that food comes first.
