Rule 1 Mass Gainer

The formula combines a carbohydrate base with whey concentrate, isolate and hydrolysate, plus creatine monohydrate. Its large serving size is intended to add energy to meals rather than replace them. Portion size should suit your overall calorie and protein needs.

For a full serving, mix two heaping scoops with approximately 590–710 mL (20–24 fl oz) of water or milk in a blender or large shaker. Use the exact gram weight printed on your selected flavor’s label. Adding milk, fruit or other foods changes the prepared nutrition values.

The large bag provides about 16 full servings. At one full serving per day, it lasts about 16 days; smaller measured portions last longer. Compare the serving weight for your flavor rather than judging by scoop volume alone.

Amounts per full labeled serving: 2 heaping scoops, measured to the selected flavor’s gram weight.

A full serving is two heaping scoops, measured to the stated gram weight. Per full serving, carbohydrates are 254 g Chocolate Fudge, 256 g Vanilla Cream, 255 g Strawberries & Cream, 252 g Cookies & Cream and 250 g Chocolate Peanut Butter. Each supplies 1 g creatine monohydrate. These values exclude milk and other additions.

Calories and protein are shown per powder serving. The complete flavor panel also lists fats, carbohydrates, sugars, sodium and other nutrients.
