About Mass gainers

Mass gainers, or weight gainers, are supplements designed to aid in gaining mass and weight. They typically have a higher carbohydrate-to-protein ratio, often around 3:1 or 2:1, meaning they contain more carbohydrates than protein. These carbs often come from sources like glucose and maltose, providing a mix of high and low-glycemic carbohydrates essential for post-workout glycogen replenishment.

Benefits Of Mass Gainers

The following are a few significant advantages of mass gainers:

  • Quick weight and mass gain
  • Enhanced recovery post intense workouts
  • Improved overall fitness results
  • Accelerated muscle growth

  • Aids in weight loss

Bulk up/Weight Gain

Weight gain can be a pain in the neck for those who struggle to eat a lot. In that case, mass gainers can be such great support. Weight gainer supplements will assist you in gaining muscle mass quicker and more effectively than chicken and rice. They're useful for skinny people who don't gain weight easily, as well as people of all body sizes who exercise really hard. They will even assist someone who is underweight and unable to get enough calories from their daily diet.


Let's face it: most weight gainers are high in carbohydrates, which cause insulin to spike, resulting in unwanted fat accumulation. On the other hand, whey protein supplements provide the body with the most important nutrient: pure protein. As a result, Ultimate Sup would advise you to use whey protein over mass gainers to build muscle and strength. 


Weight is a concern for athletes and sportspeople because it can affect their success in their respective fields. Hence, taking mass gainer supplements may not be the best idea. Athletes should instead refuel with whey protein, which has been shown to improve strength, flexibility, and athletic results. Mass gainers vs whey protein, you should choose whey protein powder. 


Many people believe that whey protein can only be consumed when they need to build muscle. This is something Ultimate Sup Singapore disagrees with. Whey protein is not only ideal for body construction, but it also has a lot of health benefits. Whey protein has been shown in studies to help control blood pressure, maintain a healthy heart, and prevent cancer.

  • Skinny people who don't gain weight easily.
  • Individuals who are underweight and unable to get enough calories

How To Use Mass Gainers?

In 1kg of energy, there are 7,700kcals (kcal=calorie). That means you'll need to consume 7,700 calories to add one kilogram. It's almost impossible to gain a kilogram in just a single day. But, if you desire to gain 1kg in a week, you'll need to add 7,700 calories a week to your everyday diet, equivalent to 1,100 calories a day. That's a perfect reason to use mass gainers. For example, one serving of Masstech Extreme contains 2050 calories. As a result, you'll need to take 0.5-0.7 servings every day, which is equal to 3-4 scoops. Meanwhile, if you use Quick Mass with 1000 calories per serving, 1-1.1 servings (4-4.5 scoops) are enough.

How To Use Whey Protein?

The DRI (Dietary Reference Intake) for protein is 0.36 grams per pound (0.8 grams per kg) of body weight. To be specific, an average sedentary man requires 56g of protein per day, while a daily average sedentary woman requires 46g of protein. However, if you tend to build lean muscle mass, the current daily reference intake of protein is 1.5-2.2g per kg of body weight. An average active man needs 105-154g of protein per day while an average active woman needs 86-127g of protein every day. People can only consume about 20-30g of protein each meal, equivalent to 60-90g of protein daily. So, using whey protein as a dietary supplement is an outstanding option. For instance, in combination with your daily diet, taking a MusclePharm Combat or Dymatize ISO100 shake once a day will meet active women’s protein requirements with 25g of protein per serving. Active guys can have two protein shakes daily to achieve their fitness goals. 

When To Take Mass Gainers?

You can take mass gainers several times a day. You know how many mass gainer scoops you need daily doesn't mean you have to take them all at once. You should consume mass gainers between meals and post-workout. Specifically, the most important time to take mass gainers is after your workout, when your body craves nutrients the most. 

When To Take Whey Protein?

You should consume whey protein immediately after your exercise. As soon as your muscles begin to relax, they will start the process of repairing micro-tears.

Since it can take 10-20 minutes for your stomach to digest the protein, many people take it after a cool-down phase.

Can I Take A Mass Gainer And Whey Protein Together?

The answer is simple. It is pointless to consume mass gainers and whey proteins at the same time. A useful mass gainer supplement contains 700-800 Kcal per 200g powder, consisting of nearly 140-160g carbohydrates and 28-36g protein (plus some fat). Whereas, a serving (nearly 25-35g) of a healthy whey product provides roughly 22-30 g protein with relatively little carbohydrates and fats.

  • A mass gainer provides adequate carbohydrates and proteins to a person looking for a bulky and muscular body. So, he doesn't need any specific protein supplements anymore.
  • If a person needs to add muscle mass while gaining just a small amount of body fat, he should use a lean mass gainer, BSN True Mass for instance.
  • If an individual just wants to build muscle, he should take a whey protein supplement. He can supplement with casein for gradual and sustained muscle recovery and development.

Skinny Guys Should Use Mass Gainers Or Whey Protein?

If you're a lean guy who wishes to gain mass first, mass gainers are a safer bet. With their high-calorie content, mass gainers are unquestionably the right supplements for weight gain and muscle gain.

Should I Use Mass Gainers Or Whey Protein To Bulk Up?

A muscle gainer is a superior supplement for bulking than whey protein. Although protein is necessary for all stages of muscle development, the calorie surplus decides how much weight you gain and whether you gain any weight at all. You won't be heavier unless you're on a surplus. Furthermore, the muscle you can gain in a calorie deficit isn't as remarkable as the size you can gain while you're bulking.
