Want to gain weight the right way? Weight gaining supplements help you put on muscle mass healthily, rather than unwanted fat. These supplements provide your body with high-energy, quality proteins that are essential for building lean muscle mass. Weight gaining supplements also contain carbohydrates that release energy slowly, supplying the right amount of calories for your workout.

The carbohydrates within the weight gainers keep your body properly fuelled whilst keeping your insulin levels regulated, which means you won’t get any unwelcome cravings. Carbs are important when you’re looking to gain weight and/or muscle, because when exercising, your body will burn the carbohydrates as fuel for energy before muscles- and you don’t want your body burning away muscles! It is also important that a little fat is included in these supplements, as this is an essential nutrient for weight gain, as long as they’re good fats, and you’re not filling up on junk food.

Sci-MX Mass System 5kg is the perfect product to use for guaranteed healthy weight gain. This supplement contains 46g of protein and 100g of carbs, so you know it’s going to pack a punch. It also contains a healthy amount of fibre, which is essential for your body’s digestion and of course, excellent for sustaining long workouts. Try the Omni-M Hardcore to see even better results, faster.
