Best Muscle-Building Stack Under $150

A good muscle building stack under $150 covers three things: enough protein, a daily dose of creatine and one extra that suits how you train. Below are three stacks from our shelves that each came in under $150 at the time of writing, with every item linked so you can check the live price in AUD. None of them replace good food and hard training, but they make both easier to stick to.

Three muscle-building stacks under $150 at a glance

Each total was under $150 when we checked prices for this guide, and each one is also over $99.99, so it ships free anywhere in Australia. Prices on this page update automatically, so if a sale ends and a total creeps over $150 you can swap one item for a similar product from our creatine range or under $50 range.

What a muscle-building stack actually needs

Muscle is built by lifting with progressive overload and eating enough food, especially enough protein. Supplements fill the gaps. The International Society of Sports Nutrition (ISSN) suggests most people who train aim for 1.4 to 2.0 g of protein per kg of body weight a day, spread across meals. For an 80 kg lifter that is roughly 112 to 160 g a day, and one or two shakes make that much easier to hit.

Creatine monohydrate is the most researched muscle-building supplement on the shelf. The Australian Institute of Sport (AIS) Sports Supplement Framework lists creatine in Group A, its highest evidence level for specific uses in sport. The ISSN creatine position stand says about 3 to 5 g a day fills your muscle stores over roughly three to four weeks, and that, combined with training, it supports gains in strength and lean mass. Plain creatine monohydrate is all you need.

The third item is a personal choice. A caffeinated pre-workout can help you train harder. Magnesium and fish oil are general health extras rather than muscle builders, so pick one only if it fills a gap in your diet.

Stack 1: the value stack

Next Generation Protein Delicious 1.25 kg is one of our best-selling proteins over the last six months. It is an Australian-made blend of whey isolate, hydrolysate and concentrate with 24 g of protein per 28 g serve (Chocolate), and the 1.25 kg bag holds 44 serves. That works out to about $2.27 per shake at the time of writing, the most protein serves for the money of the three stacks.

Add Beast Labs Creatine Monohydrate 250 g at $19.95. It is a single ingredient, 5 g of micronised creatine monohydrate per serve, and the tub lasts 50 days at one serve a day. Round it out with Nature's Best Magnesium Glycinate, which gives 200 mg of elemental magnesium per two-capsule serve. Be realistic about what magnesium does: the AIS places it in Group C for sport performance, so it will not build muscle. It is a sensible top-up if your diet is light on nuts, seeds, wholegrains and leafy greens. Adults should keep magnesium from supplements to 350 mg a day or less, the upper limit in the Australian Nutrient Reference Values, and one serve sits well under that.

Stack 2: the training-day stack

Rival Whey 2 lb costs $64.95 and blends whey isolate, concentrate and native whey isolate for 25 g of protein per 32 g scoop. It is sweetened with stevia and monk fruit, and Rival states it is Informed Choice certified. Check the product page for flavours in stock.

Pair it with Legit Creatine Monohydrate 500 g, our best-selling creatine over the last six months. One 5 g scoop a day means the bag lasts 100 days, about $0.50 a serve. The extra here is Fresh Pre-Workout, which lists 3 g of L-citrulline, 1.6 g of beta-alanine, 1 g of betaine and about 180 mg of caffeine per 8 g scoop. A full two-scoop serve has about 360 mg of caffeine, well above the 200 mg single serving that FSANZ suggests for adults, so stick to one scoop and count any coffee or energy drinks you have that day.

Caffeine is also in AIS Group A. The ISSN caffeine position stand found that 3 to 6 mg per kg of body weight, taken about 60 minutes before exercise, improves performance across many types of exercise. If you train in the evening, skip it or go stim-free, because caffeine can stay in your system for hours and affect your sleep.

Stack 3: the all-rounder stack

Legit Whey Protein 2 lb is Australian made and costs $79.95. It blends whey concentrate, whey isolate and milk protein concentrate for 23.4 g of protein per 30 g serve (Chocolate Milkshake), with 30 serves per bag. Add Evogen Essential Series Creatine Monohydrate at $35.00, a 5 g scoop of micronised creatine with about 60 serves per tub. Evogen's current label carries the NSF Certified for Sport logo, which matters if you compete in tested sport.

The extra is Rule 1 Fish Oil: one softgel a day gives 1 g of fish oil with 180 mg of EPA and 120 mg of DHA, and the bottle holds 100 softgels. Fish oil sits in AIS Group B, meaning the evidence is emerging but not yet strong. Choose it if you rarely eat oily fish such as salmon or sardines, not because you expect bigger arms.

How to take your stack

• Protein: have a shake after training or at any meal that is light on protein. The ISSN says your total for the day matters more than exact timing.
• Creatine: take 3 to 5 g every day, rest days included. Mix it into your protein shake so you do not forget. A small rise in body weight in the first few weeks is normal and mostly water stored in muscle.
• Pre-workout: about 30 to 60 minutes before training, and never more than the label says.
• Magnesium or fish oil: with a meal, as directed on the label.

If you have a medical condition, take regular medication or are under 18, talk to your GP before starting a new supplement.

Which stack should you choose?

Choose the value stack if you want the most protein for your money and a simple daily routine. Choose the training-day stack if you like a pre-workout and want our best-selling creatine. Choose the all-rounder stack if you prefer Australian-made whey and want an omega-3 top-up. All three share the same core of daily protein and creatine, which is where most of the benefit sits.

FAQs

What is the best muscle-building stack for beginners?

Start with the two supplements with the strongest evidence: a protein powder to help you reach your daily protein target, and creatine monohydrate at 3 to 5 g a day. Both are simple to take and fit easily under $150. Add a third product only if it solves a real problem, such as low energy before training or a diet with little oily fish. Training consistently and eating enough food will still do most of the work.

Do I need a pre-workout to build muscle?

No. A pre-workout does not build muscle by itself. Caffeine, the main active in most stimulant pre-workouts, can help you train harder, and the AIS rates it Group A for performance. If you already drink coffee before training, train late in the day or are sensitive to caffeine, you can skip the pre-workout and put that money towards a bigger tub of protein instead.

Should I take creatine on rest days?

Yes. Creatine works by keeping your muscle stores topped up, so take 3 to 5 g every day, including rest days. Timing is not critical, so pick a time you will remember, such as with breakfast or in your protein shake. A loading phase is optional: skipping it simply means your stores take around three to four weeks to fill instead of about a week.

How long does a stack under $150 last?

It depends on the products. In the value stack, the 1.25 kg protein gives 44 shakes, the creatine lasts 50 days and the magnesium 30 days. The training-day stack gives 27 protein shakes, 100 days of creatine and 40 single scoops of pre-workout. The all-rounder gives 30 shakes, about 60 days of creatine and 100 days of fish oil. Protein usually runs out first.

Is creatine safe to take every day?

The ISSN position stand concludes that creatine monohydrate is safe for healthy people at recommended doses, including long-term use of 3 to 5 g a day. The most common change is a small rise in body weight from extra water stored in muscle. If you have a kidney condition, take regular medication, are pregnant or are under 18, talk to your GP before you start.
