When to use this
An athlete or parent asks whether they should buy a product, and the conversation needs a filter before it needs an answer.
- A supplement request arrives via social media hype or a teammate's recommendation.
- A family is spending on powders while the grocery list is still thin.
- You want one repeatable framework for every product question this season.
