How many scoops each tub size holds

Servings in an unopened tub by scoop weight; the same as days if you have one a day. The label gives the serving size and the servings per container. Rounded down.

The quick numbers

With a 30 g scoop, a 1 kg tub is 33 servings and lasts just over a month at one a day. A 2 kg tub is 66, about two months. A 5 lb tub (2.27 kg) is 75, two and a half months. If you have two a day, halve the days.

A scoop is not a measurement

How much a scoop holds changes with the brand and with how you fill it, level or heaped. The label gives the serving size in grams and the servings per container. If you want the date to be right, weigh one scoop once and use that number.

Pounds and kilos

Many tubs are sold in pounds. A pound is 453.6 g: 2 lb is 907 g, 5 lb is 2.27 kg and 10 lb is 4.54 kg. The table above already has them in grams.

What the calculator does not tell you

How much protein to have, or when. That is for you, your coach or a professional. The calculator only counts what you tell it.
