Flavour fights are entertainment. Scoop maths decides who wins.
TL;DR: Divide tub price by (serves × protein grams per serve), then normalise to $ per 25 g protein. That’s the fair fight in AUD.
The formula
$ / 25 g protein = (tub price AUD ÷ total protein grams in tub) × 25Or: price ÷ serves ÷ protein-per-serve × 25.
Do it on the label in front of you. Promotions change weekly.
What to read on the label
- Protein per serve (as sold, not fantasy “dry basis” games)
- Serve size in grams
- Serves per container
- Added sugars / junk if that matters for your cut
Lactose wrecks you? Isolate (WPI) can be worth the premium. That’s a gut call, not a detox — full comparison: Whey concentrate vs isolate.
Example framing (illustrative)
| Tub type | What usually wins |
|---|---|
| Big WPC bag on sale | Often best $/25 g |
| Premium WPI | Worth it for lactose or lean macros — not ego |
| “Mass gainer” | Cheap calories; not the same as protein economics |

Don’t
