Advice
Short answers. The dose on the label still comes first.
When do I take creatine?
Five grams, any time of day you will remember. You do not need a loading week.
Is the whey a meal?
No. It is a scoop of protein. Eat food around it.
Do I need electrolytes every day?
Use them when you sweat for a long time. A short walk does not need a pouch.
Can I take magnesium with casein?
Yes. The evening stack is that pair. Take the printed servings, not both scoops of each.
