CRUCIAL MASS is a high-calorie, premium weight gaining formula containing key ingredients which are needed to help the body gain quality muscle and weight, alongside a healthy weight-training regime.

Gaining weight can be a difficult task for many athletes and added size and muscle mass can be a huge advantage in certain roles in many sports. By using a clean carbohydrate formula with key ingredients such as sweet potato, quinoa, oats, maltodextrin, and premium protein powders (such as whey protein concentrate, and whey protein isolate), we believe that we have created the ultimate mass gain formula. Our premium mass-gaining formula delivers 1225 calories per serving with added BCAAs to help recovery and added creatine monohydrate to help increase performance.

Quality, effectiveness and convenience are key in this carefully formulated instantised ready to mix and drink shake. This product is ideal for post workout, pre workout, and in between meals to increase your daily, weekly, and monthly calorie intake, helping you add quality calories to put your diet in a calorie surplus to help gain body weight and muscle mass.


Ingredients: Carbohydrate blend: maltodextrin, oats, sweet potato, quinoa. Protein blend: Whey protein concentrate (wpc) (milk), whey protein isolate (wpi) (milk). Glycine, creatine monohydrate, BCAA blend (leucine, iso leucine, valine), flavouring, natural colouring, sweetener (sucralose). Cocoa powder for chocolate-based flavours. Natural colour for vanilla and banana flavours. FD&C red E129 for strawberry flavour).
