What to Compare Before Buying
- Pack size: This version is 5.45 kg. Compare that with the amount you want to keep in stock and store.
- Servings: The pack is stated as 16 servings. Check whether that suits how often you plan to use it.
- Flavour: The flavour is chocolate. Choose the flavour you are most likely to use consistently.
- Serving preparation: One serving is mixed with 710 ml of water or plant milk. Check whether that fits the way you plan to prepare it.
Before You Decide
Confirm the chocolate 5.45 kg version and the 16-serving pack size before choosing an offer. If the serving mix volume matters to you, check that 710 ml fits your preparation routine. This is a mass gainer rather than a standard protein powder, so the calorie-focused format is the main point to compare.
