Product Overview

Serious Mass

Serious weight gain requires serious calories. However, those who need the extra calories most often have the toughest time consuming enough of them. For many aspiring to be bigger, a highly active metabolism, weaker appetite and on-the-run lifestyle can make it a real challenge to consume enough calories through whole foods alone. SERIOUS MASS™ is the ultimate in weight gain formulas. With 1,250 calories per serving to boost daily calorie intake, 50g high protein to support muscle growth and repair, over 250g carbohydrates helping support muscle recovery , and now with 3 g added Creatine to support performance per serving, you’ve got nothing to lose and lots to gain. It is time to stop thinking small and get serious – SERIOUS MASS™

Micronised Creatine Powder

Creatine is proven to increase performance during high intensity training. From the World's No. 1 Sports Nutrition brand, each serving supplies a full 3.4 g of Creatine Monohydrate to increase muscle power in successive bursts of short-term, high intensity, repeated exercise*. Optimum Nutrition MICRONISED CREATINE POWDER always mixes easily and unlike other Creatine powders, there is no gritty taste or texture.

ON Shaker 600ml

Make mixing your drinks easier with the Optimum Nutrition protein shaker. Just add water to your favourite Optimum Nutirition protein powder and enjoy, lump free!
