FAQs
How many serves are in each tub?
Rule 1's current Source7 tubs are 1.8 lb (820 g) with 20 serves and 4 lb (1.8 kg) with 44 serves, based on a 41 g scoop. Our size options are listed as 2 Lbs and 5 Lbs, so check the net weight and serves printed on your tub.
How is Source7 different from a whey isolate?
Source7 mixes seven proteins, including whey concentrate, micellar casein and pea protein, and adds a creamer. Per scoop it gives 22 g of protein, 10 g carbohydrate and 4.5 g fat (Chocolate). For comparison, R1 Protein whey isolate lists 25 g protein, 3 g carbohydrate and 0.5 g fat per Chocolate Fudge scoop.
Does it contain sugar?
The Chocolate panel lists 5 g of total sugars per serve and 0 g of added sugars, so the sugar comes from the milk-based ingredients. It is sweetened with sucralose and acesulfame potassium.
When should I take it?
Rule 1 says any time. It suits a shake after training or between meals. The NIH Office of Dietary Supplements cites 1.2 to 2.0 g of protein per kg of body weight a day for athletes, so daily total matters more than timing.
