Quick Verdict
MyProtein Creatine Monohydrate and Optimum Nutrition Micronized Creatine are both reliable creatine products that deliver 5g of creatine monohydrate per serving. The core ingredient is identical, and your muscles will respond the same way to either product. The key differences lie in sourcing, certification, pricing, and availability.
Choose MyProtein if: You want the best value per serving (RM1.10 vs RM2.00), appreciate offline availability at Watsons Malaysia, and ALS third-party testing is sufficient for your needs.
Choose ON if: You need Creapure sourcing for maximum purity assurance, require Informed Sport certification for drug-tested sports, and are willing to pay nearly double per serving for premium quality credentials.

Value for Money
This is where MyProtein dominates. At 100 servings per container versus ON's 60, you get 67% more servings from MyProtein. The cost per serving difference is dramatic: RM1.10 vs RM2.00 — meaning ON costs 82% more per serving.
Over a year of daily use (365 servings), the cost difference is substantial:
- MyProtein annual cost: approximately RM402
- ON annual cost: approximately RM730
- Annual savings with MyProtein: approximately RM328
Winner: MyProtein — Significantly better value with more servings at a much lower per-serving cost.
Quality & Testing
Optimum Nutrition uses Creapure, the gold standard in creatine purity from AlzChem in Germany, and carries Informed Sport certification for banned substance screening. This makes ON the safer choice for competitive athletes subject to anti-doping testing.
MyProtein uses standard creatine monohydrate tested by ALS (Australian Laboratory Services) for potency and purity. While this provides good quality assurance, it does not include the specific banned substance screening that Informed Sport offers.
Winner: Optimum Nutrition — Creapure sourcing and Informed Sport certification provide superior quality assurance.
Availability in Malaysia
MyProtein has a unique advantage in Malaysia: it is available at Watsons stores nationwide through its official distributor, EJI Nutrition. This makes it one of the few international creatine brands you can buy in a physical retail store in Malaysia without visiting a specialty supplement shop.
ON is widely available on Shopee and Lazada Malaysia and at specialty retailers like Proteinlab Malaysia and LAC (formerly GNC). Both brands have reliable stock availability in Malaysia.
Winner: MyProtein — Watsons availability gives MyProtein unmatched offline convenience for Malaysian consumers.
Mixability & Taste
ON's micronized formula dissolves slightly better than MyProtein's standard grind. MyProtein's non-micronized version can leave a bit more sediment in water, though it still mixes adequately in shakes and juice. Both are unflavored.
Winner: Optimum Nutrition — Micronized formula provides smoother mixing.
Our Recommendation
For most Malaysian gym-goers: MyProtein. The value is exceptional, Watsons availability makes it convenient, and the creatine monohydrate is equally effective. At nearly half the price per serving, the savings add up over months and years of consistent supplementation.
For competitive athletes in drug-tested sports: Optimum Nutrition. The Informed Sport certification is worth the premium if you face anti-doping testing.
For Muslim consumers: Neither product carries JAKIM certification. Consider AGYM or PharmaNutri for halal-certified options.
