Struggling to Gain Weight? ON Serious Mass Puts You over the Top

Ectomorphs tend to be naturally slender with super-charged metabolisms. They can eat all the carbs they want and still have trouble gaining. Achieving the muscular build they desire takes a serious number of calories. But for a hard gainer getting these all in can be tricky. Some people have a real challenge consuming enough calories through eating. Their weak appetites and active lifestyles hold them back from getting to the size they’d like. But taking ON Serious Mass, along with dedicated weight training, will enable you to build a physique you’ll be proud to show off at the pool (think, BIG).

Each serving packs in over 1,250 calories, 50 g protein, 250+ g carbohydrates and 25 vitamins and minerals, as well as glutamine and creatine. Here’s the breakdown:

  • 1,250 calories per 2 scoops Serious Mass mixed with 710 mL of water; 1,630 calories with low fat milk
  • 50 g protein from combined fast and slow digesting sources, including whey, egg and casein
  • 250+ g carbs with NO ADDED SUGAR to fuel your extreme workouts and aid in replenishing glycogen stores
  • Enriched with L-glutamine and glutamine peptides, creatine, choline, inositol, MCTs and PABA
  • 25 vitamins and essential minerals, with a boost of B-vitamins and antioxidants.

How to Bulk Up Like a Champ with Our Serious Weight Gainer

For best results, put 2 heaping scoops Serious Mass with 700 mL water in a blender and blend for approximately one minute. Toss in a few ice cubes and whiz 30 seconds more. Using low or non-fat milk in place of water will result in a delicious thick, creamy shake that is even more calorie-dense. You could also add nutritious high-calorie ingredients, like peanut butter, avocado, or full fat yoghurt. This mass gainer also works well when stacked with ON 100% gold standard Whey Protein too.

Drink ½ to one serving between each meal to add calories and maintain a positive nitrogen balance. Use ½ to one serving of Serious Mass 30 to 45 minutes post-workout in order to obtain maximum recovery gains. Drink ½ to one serving about an hour before bedtime to aid muscle recovery throughout the night. Just starting out with Serious Mass? We recommend a single scoop daily for week 1 and gradually increasing to two scoops several times per day for a serious weight gain effect.

Achieve Lean Muscle Mass with Diet, Training & Proper Recovery

You will achieve top results with Serious Mass nutritional support when you combine it with intense weight training (3-5 times weekly) and a sensible diet of whole, natural foods. In addition, your ability to make hard gains requires sufficient muscle recovery time. Allow at least 48 hours between working out the same body parts, and you will soon find yourself making those serious gains you desire.
