Questions & Answers

Can I gain up to 10kgs in a month
Hi Flavian, 10 kg in one month isn't a realistic target. At that speed most of the weight would be fat and water, not muscle. A steadier pace, around 0.5 to 2 kg a month, is the usual range, and it depends on your starting weight, how much you eat, your training and your sleep. Serious Mass is a high-calorie shake that helps you eat more. It doesn't replace a proper diet or training. If you tell us your weight and goal, we'll help you work out a sensible plan.
