All three are pure creatine monohydrate, the form with the most research behind it, so the best one comes down to price, size and testing. Beast Labs Creatine and the Legit 1 kg bag cost the least per 5 g serve, at about 40 cents. ON Micronized Creatine costs a little more but is banned substance tested under Informed Choice, according to Optimum Nutrition. Legit 300 g is the easiest place to start at $39.95.

Legit Creatine: best all-rounder
Legit is a single-ingredient micronised creatine monohydrate, unflavoured, with 0 kJ and 0 mg sodium per 5 g serve. It comes in three sizes, so you can start small and move to the 1 kg bag once you know you will take it every day.
ON Micronized Creatine: best for tested athletes
The label lists "Other ingredients: None", and Optimum Nutrition states it is banned substance tested under Informed Choice. A Sport Integrity Australia survey found 35% of 200 supplements bought online contained a prohibited substance, so if you are drug tested, choose a certified product and check your batch.
Beast Labs Creatine: an easy first tub
At $19.95 for 50 serves of 5 g, Beast Labs is a low-cost first tub. It is 100% micronised creatine monohydrate with nothing else added.
How to take creatine
- Daily dose: the ISSN suggests 3 to 5 g a day. Taking it every day matters more than timing.
- Loading (optional): about 0.3 g per kg of body weight a day (roughly 20 g, split into four doses) for 5 to 7 days fills your muscles faster, then drop to 3 to 5 g.
- Weight gain: expect a small rise in scale weight in the first weeks from water stored in muscle.
- Safety: the ISSN considers creatine monohydrate safe for healthy people at recommended doses. Check with your doctor if you have kidney disease or take regular medication.
The AIS places creatine in Group A of its Sports Supplement Framework, meaning strong evidence for specific uses in sport. Read more in our best creatine guide.

FAQs
What is the best creatine in Australia?
For most people, a plain creatine monohydrate is best. Legit and Beast Labs cost the least per 5 g serve, while ON Micronized Creatine is banned substance tested under Informed Choice according to Optimum Nutrition, which suits tested athletes. All three are single-ingredient creatine monohydrate.
How much creatine should I take a day?
The ISSN suggests 3 to 5 g a day. You can load with about 20 g a day, split into four doses, for 5 to 7 days to fill your muscles faster, then go back to 3 to 5 g. Taking it consistently matters more than timing.
Is micronised creatine better?
Micronised creatine is ground finer so it mixes more easily. It is still creatine monohydrate, so the effect is the same. All three products in this guide are micronised.
Does creatine cause bloating or hair loss?
Creatine can cause a small gain in water weight in muscle, especially when loading. Stomach upset is more likely with large single doses, so split loading doses. The evidence linking creatine to hair loss is very limited and comes mainly from one small study, so it has not been shown to cause hair loss.
