Introduction To Weight Gainers


Go From Half Pint To Hulk*

Many people have trouble putting on muscle mass. The old saying is true - you have to eat big to get big. It can be difficult to keep your calorie intake up, and those of us with fast metabolisms burn most of what we take in.

But have no fear because weight gainers are here! Keep your body packed with the right ingredients and sculpt your body into a rock-solid powerhouse!* Weight gainer supplements may help with:

  • Quality protein and carbohydrate source
  • Convenient
  • Packed with high quality calories

Add Weight On With Ease*

One of the biggest reasons would-be gainers struggle with packing on muscle is because they are not taking in nearly enough calories to generate new muscle tissue. It's not unheard of to see people consuming 4000+ calories a day - a challenge in itself along with your actual training.

If your head is spinning just thinking about how to cram enough protein, carbs, and calories in each day to fuel your body bulking, weight gainers are a convenient and high-quality alternative.

By cramming an awesome ratio of protein, carbs, and calories into one convenient powder, you can get the extra fuel you need without the hassle of preparing a meal. Just mix it up and you are set to go!


Supersize Your Gains*

Hitting a muscle building plateau is one of the most frustrating situations for anybody trying to put on some serious muscle mass.

Weight gainers are different than normal protein powders because they contain more protein, carbohydrates, and calories per serving. By adding a weight gainer shake to your daily diet, you can support:

  • Plenty of good calories, protein, and carbs for building muscle*
  • Recovery from workout sessions with nutrient availability*
  • The prevention of catabolism*

No Force-Feeding Necessary

Contrary to popular belief, weight gainers aren't only for those trying to become Mr. Olympia. In fact, many people who have extremely fast metabolisms and have trouble keeping on weight will also benefit from a weight gainer. People involved in endurance-intensive lifestyles that are trying to build some muscle mass can also benefit from a weight gainer.*

Likewise, anyone who is having trouble getting the proper carbs, calories, and protein from their normal diet may also want to consider a weight gainer, since it can help provide your body with important nutrients to fight dangerous weight loss.* Whether trying to gain 5, 10, or 30 pounds of muscle, weight gainers are your go-to product!*

Not Sure What To Pick?

Once you've decided a weight gainer is something to go for, there's still the decision of which one to go with. There are a few things to consider like:

  • Pick a calorie level that fits your nutrient needs
  • Be careful about fat content
  • Protein content at least 40 grams

For those looking to put on 5-10 lbs, go for a leaner calorie gainer. Alternatively, those looking to put on 30+ lbs should get something having at least 600 calories per serving.

An Easy Filling Station For Mass*

Once you have your weight gainer, the next thing you want to think about is how to use it. Ideally, you should be using the weight gainer between normal meals when you need to get those extra calories in your body.

Some people will try and use the weight gainer with their main meals, but it is most beneficial to consume your calories evenly throughout the day. Have you ever tried eating 4,000 calories in one sitting? It's hard for most people!

See which strategy works best for you. Spread it out behind 4-5 shakes or 2-3 a day. As long as you make your protein/carb/calorie intake for the day, you will be one step further to success!
