Are your supplements third-party tested?

Many of our products undergo third-party testing, and we stock a dedicated range of third-party tested products. All our stock is sourced directly from authorised NZ distributors.

Selected products across our house brands, including Swoleys, Pack Nutrition, Athletech and NoWhey, undergo third-party testing. Depending on the product, this may include HASTA (banned-substance) testing, protein and creatine content analysis, contaminant testing and heavy metals testing. Testing varies by product, so it isn't applied to every item. Third-party testing means an independent lab has verified what's in the product. We're working on the best way to list our test results online. In the meantime, you can request test results for a specific product directly by emailing [email protected]. Browse our Third Party Tested range, and read more about our sourcing and quality standards on our Transparency page.

What supplements should a beginner start with?

For most people starting out, a quality whey (or plant) protein plus creatine monohydrate covers the essentials. Add a pre-workout only if you want a training energy boost.

Protein powder helps you hit your daily protein target for muscle repair and recovery. Browse protein.
Creatine monohydrate is one of the most researched supplements for strength and muscle. Browse creatine.
Pre-workout is optional, for energy and focus before training. Browse pre-workout.

Not sure where to start? Our in-store team can build a plan around your goal. Find your nearest store.

How much protein do I need per day?

A common guideline for active people is around 1.6 to 2.2 grams of protein per kilogram of bodyweight per day, spread across meals.

For example, an 80 kg person aiming to build or maintain muscle might target roughly 130 to 175 grams a day. Protein powder is a convenient way to top up if you fall short from food alone. Your needs vary with goals, training and health, so treat this as a general guide. Browse protein.

What's the difference between whey, whey isolate and plant protein?

Whey concentrate is the everyday all-rounder, whey isolate is lower in lactose and carbs, and plant protein is dairy-free for vegan or lactose-intolerant users.

Whey concentrate: Great value, mixes well, suits most people. Browse whey.
Whey isolate: More filtered, so lower in lactose, carbs and fat. A good pick if whey concentrate upsets your stomach. Browse isolate.
Plant protein: Dairy-free, made from sources like pea and rice. Suits vegan and lactose-intolerant users. Browse plant protein.

Is creatine safe, and how do I take it?

Creatine monohydrate is one of the most researched sports supplements and is widely considered safe for healthy adults. A typical dose is 3 to 5 grams per day, every day.

How to take it: Mix 3 to 5 grams into water, juice or a shake. Timing doesn't matter much, so pick a time you'll remember. Consistency is what counts.
Loading is optional: Some people load with around 20 grams a day (split into 4 doses) for 5 to 7 days to saturate faster, then drop to 3 to 5 grams. You can skip loading and just take 3 to 5 grams daily.
Stay hydrated and, if you have a medical condition or take medication, check with a healthcare professional first.

Browse creatine.

What does protein do?

Protein supports muscle repair, recovery and maintenance.

When you train, you create micro-tears in muscle. Adequate protein, together with rest, supports repair and adaptation. It also helps with feeling full, which can support weight management. Explore our protein range.

What does a fat burner do?

Fat burners may support weight management by boosting energy, managing appetite or supporting fat metabolism, alongside diet and training.

They come as pills or powders, often containing caffeine or botanical extracts. They aren't a substitute for good nutrition and exercise. View fat burners.

What's the difference between BCAAs and EAAs?

EAAs contain all 9 essential amino acids. BCAAs (leucine, isoleucine and valine) are just 3 of those 9.

EAAs give a more complete amino profile for muscle support. BCAAs can still be useful, especially intra-workout, but they're a subset of EAAs. See our amino acids.

Do you stock vegan, gluten-free or dairy-free options, and can you help with allergens?

Yes. Use the filters on our category pages or check the nutrition label. If you're navigating allergens or intolerances and aren't sure what's suitable, contact our team for assistance before buying.

Browse plant-based protein, gluten-free protein and lactose-free protein. Supplements can contain allergens such as dairy, soy, gluten and tree nuts, or be made in facilities that handle them, so always check the label. If you're unsure, email [email protected] or ask our in-store team and we'll help you find a suitable option.

Do supplements have a best-before date?

Yes. Supplements carry a best-before date. A best-before date relates to quality, including freshness, taste and potency, not safety.

Best-before vs use-by: Best-before relates to quality. Follow the label and use your judgement.
Common changes: Hygroscopic powders like pre-workouts and some fat burners may clump, and potency can slowly decrease over time.
Storage matters: Keep sealed, in a cool, dry place away from humidity and heat.

How should I store supplements, and why does my powder clump?

Store sealed in a cool, dry place. Clumping is normal in powders that attract moisture and usually doesn't affect potency.

Keep it dry: Away from humidity and heat, with the lid firmly closed.
Clumping is common: Ingredients like citrulline and some flavours absorb moisture. Break up the clumps. If the product has been stored properly and is within its best-before window, potency is typically unaffected.

Is it safe to take supplements while pregnant or breastfeeding?

Some supplements may be suitable during pregnancy or breastfeeding, but not all supplements are safe or appropriate. Always check with your doctor, midwife or pharmacist before taking any supplement while pregnant or breastfeeding.

Medications, age limits and WADA / banned substances

Medications and health conditions: If you take prescription medication or have a medical condition, consult a healthcare professional before using any supplement.
Age: Stimulant-containing products are intended for healthy adults. Always read the label warnings.
Tested athletes: If you're subject to drug testing, check ingredients against the latest WADA and NSO lists and confirm with your team or doctor. We can't guarantee compliance for every federation.
