Our Top Choices For Weight/Mass Gainers For Skinny Guys (fast metabolisms):

If you’re a skinny guy struggling to gain weight, we have tailored supplement recommendations for you. These will help with your weight gain and muscle-building goals.

Our top choice for beginners is Mutant Mass Extreme, given its balanced formula and impressive results.

1. Mutant Mass Extreme (Top Choice)

  • This powerful mass gainer is designed specifically for those who find it difficult to add weight. With a rich blend of proteins, carbohydrates, and healthy fats, combine it with Mutant Creakong CX8 during workouts for optimal results. This combination not only fuels your workouts but also aids in recovery and muscle growth, making it the best recommendation for those new to supplements.

2. Applied Nutrition Critical Mass 

  • This dynamic duo supports weight gain and muscle growth effectively. Critical Mass provides the necessary calories and nutrients, while adding Applied Nutrition Creatine can enhance strength and explosive power, maximizing your training efforts.

3. USN Hyperbolic Mass

  • Formulated with fast metabolisms in mind, this mass gainer is particularly beneficial for skinny guys. It includes creatine in its ingredients for added benefits, helping to increase muscle size and improve performance. This supplement is a great choice if you’re looking for an effective way to pack on pounds while supporting your workout regimen.

4. Amino Drinks

  • Additionally, consider taking an amino drink first thing in the morning. Options like Mutant Geaar and CNP Loaded EAAs are excellent choices due to their straightforward ingredients. This small addition to your daily routine can significantly aid in gaining weight and muscle by promoting recovery and preventing muscle breakdown throughout the day.

 

By incorporating these supplements into your diet, especially starting with Mutant Mass Extreme, you can effectively target your weight gain goals, making your journey as a hard gainer or skinny guy much more manageable and successful.

Best Weight Gainers For Skinny Guys With Slower Metabolism:

If you have a slower metabolism, selecting the right weight gainer is crucial.
The following options can help you achieve your muscle-building goals:

1. Usn Muscle Fuel Anabolic

Muscle Fuel Anabolic is an excellent all-in-one weight gainer. It provides a perfect balance of calories and nutrients, allowing you to add weight and muscle at a steady rate without losing your shape. This gainer contains a blend of proteins, carbohydrates, and essential nutrients aimed at supporting muscle recovery and growth.

2. Optimum Nutrition Serious Mass

Optimum Nutrition Serious Mass is another fantastic all-in-one solution for weight gain. While it is calorie-dense, consider reducing the serving size if you’re concerned about gaining weight too quickly. This flexibility allows you to adjust your intake based on your unique needs and goals, making it suitable for those with a slower metabolism.

Why Choose Low-Calorie, Nutrient-Dense Weight Gainers?

For individuals with a slower metabolism, opting for weight gainers with a lower calorie count but rich in essential nutrients can help maintain a more balanced diet while still promoting weight gain.

These products are formulated to provide all the necessary macronutrients (proteins, carbs, fats), which you can adjust according to your serving size to suit your dietary requirements.

Other Top Recommendations for Weight Gain:

When considering your weight gain journey, think about your goals and body type. Here are some of the best weight gainers for building quality muscle:

  • Mutant Mass: Perfect for those ready to pack on serious muscle without compromising their physique.
  • CNP Mass XL: A balanced formula that supports muscle growth while keeping fat gain in check.
  • BSN True Mass: Offers a blend of protein, carbs, and healthy fats to help you reach your weight gain targets.

Determine Your Weight Gain Strategy

Before diving into supplementation, it’s essential to decide how you want to gain weight.

  • Fast Weight Gain: If you’re willing to sacrifice a lean physique for quick muscle gain and plan to cut down later, products like Serious Mass, Mutant Mass, or Critical Mass are ideal choices.

  • Gradual Weight Gain: If you prefer a more measured approach to adding weight, focus on nutrient-dense products that allow for incremental increases without excessive fat gain.

Fast Weight Gain & Muscle Building
For skinny guys who struggle to add weight and aim to pack on more pounds quickly, along with muscle, a well-rounded supplement is your ticket to success.

Weight gainers, comprising protein powders coupled with added carbs, BCAAs, and extra calories, like Usn Hyperbolic and Mutant mass Extreme especially suit those with swift metabolisms.

Top tip: Consuming the protein shake immediately after a workout since it helps prevent muscle breakdown and facilitates weight and muscle gain.

Controlled Weight Gain & Muscle Development
For slim men who wish to gain muscles faster but don’t want a rapid weight gain (potential extra fat), Usn Muscle Fuel Anabolic is a great supplement or if you don’t want the extra calories we would recommend a creatine powder and a whey protein powder, this way you can better control your weight gain and reduce calorie intake but you definitely need the extra protein to build the muscle and gain the weight.

If you don’t want to take a weight gainer a great supplement to add would be a Amino or BCAA drink in the morning and around your workout to help build and prevent muscle break down.

The choices we have are all great for weight and mass gain, they have great flavours and all mix well in shakers and a price to suit all budgets.

Weight Gainers vs. Mass Gainers: Understanding the Key Differences

In the world of bodybuilding, gaining muscle mass is a common goal for many individuals. To help in this process, there are various supplements available, including weight gainers and mass gainers.

While these terms are often used interchangeably, it is essential to understand the distinctions between them. This article aims to shed light on the dissimilarities between weight gainers and mass gainers, helping you make an informed decision regarding which one suits your needs best.

Weight gainers primarily focus on helping individuals increase their overall body weight. They contain a higher ratio of carbohydrates to protein and are rich in calories. Weight gainers are typically marketed towards individuals with a fast metabolism or those struggling to consume a sufficient number of calories from their regular diet alone.

Mass gainers, on the other hand, are designed to promote lean muscle mass development. They generally contain a balanced ratio of carbohydrates, proteins, and healthy fats, along with essential vitamins and minerals. Mass gainers are commonly used by individuals looking to enhance muscle growth and recovery after intense workouts.

Weight gainers tend to have a higher carbohydrate content to provide a quick source of energy. They often contain a lower proportion of protein, ranging from 15-25 grams per serving. These supplements are typically packed with simple and complex carbohydrates, which help in replenishing glycogen stores and fueling intense workouts.

Mass gainers have a more balanced macro-nutrient profile, including a higher protein content, typically ranging from 30-50 grams per serving. These supplements aim to provide the necessary amino acids for muscle repair and growth. Additionally, mass gainers often contain a moderate amount of carbohydrates and healthy fats, aiding in sustained energy release and overall muscle development.

Weight gainers are known for their high-calorie content, often ranging from 500 to 1,200 calories per serving. These supplements are ideal for individuals with high caloric needs or those aiming to gain weight rapidly. However, it is important to monitor calorie intake carefully to avoid excessive weight gain and prioritize a healthy lifestyle.

Mass gainers generally provide a more moderate calorie count, ranging from 300 to 700 calories per serving. This allows for a controlled calorie surplus, facilitating lean muscle gain without excessive fat accumulation. Mass gainers are suitable for individuals seeking a more gradual and controlled approach to muscle development.
Usage and Timing:

Weight gainers are typically consumed between meals or as meal replacements. They are often taken during the day or before workouts to provide a calorie-dense source of energy. Individuals aiming to increase overall weight and muscle mass often incorporate weight gainers into their daily nutrition plans.

Mass gainers are commonly consumed post-workout to facilitate muscle recovery and replenish glycogen stores. The balanced macro-nutrient profile of mass gainers makes them an effective option for muscle building, especially when combined with regular resistance training.

While weight gainers and mass gainers share the common goal of promoting weight and muscle gain, their specific purposes, macro-nutrient compositions, calorie contents, and timing of usage differ significantly. Understanding these differences is crucial in selecting the appropriate supplement to align with your fitness goals.

Is Mass Gainer Good For Skinny Guys?

Mass gainer or weight gainers are great for skinny guys who want to bulk up quickly. Mass gainers are for people who don’t mind all the weight they will gain to be all muscle.

A weight gainer is great for people who want to put on weight a little slower but for skinny guys with faster metabolisms to support the muscle building better, but a mass gainer will help with the calorie in take needed to gain the muscle. Mass gainers and weight gainers work best when taken between meals and immediately after your training session.

 

Is It Good To Take Mass Gainers For Beginners?

Absolutely, when your first starting out and wanting to build muscle and or add weight quick I would definitely use a mass gainer as they are generally all in one protein shakes and a great way to get started in adding mass.

How Do I Use A Mass Gainer?

You need to determine the amount of weight you are wanting to gain and your own body’s metabolism, If you are a skinny guy with a fast metabolism trying to add weight then you will need to consume excessively, this is where a mass gainer will be good because you can eat all you need and add a couple of mass gainer protein shakes in to your day to really add the weight.

I would recommend drink one straight away when you wake up and one as soon as you finish training. If you are trying to add weight but not don’t struggle as much with adding weight but want to gain muscle then you need to determine the food you are going to have, the amount of calories, protein, carbohydrates etc and then check the amounts in your chosen mass gainer protein and add in your day as needed to boost the muscle growth. Mass gainers protein can also be used as a great substitute if you can not or don’t have time to consume everything you need in your day.

If you are trying to add mass fast then the aim can be to consume excessively, so if your food intake covers your daily requirements then a mass gainer protein shake can give you the extra nutrients and calories to add the weight and refill your body nutrients store straight after training. But no matter your requirements from a mass gainer protein definitely have a shake straight after training.

Why Would I Use A Mass Gainer?

The main reasons for taking weight gainer protein shakes are reasonable obvious, to gain weight/add mass. If you are a person who struggles to gain weight or maintain weight they are great for you.

But also they are good for people who struggle to eat the amount of food needed in a day, like maybe too busy and just don’t have the time to squeeze all your meals in. They are also good for people who don’t have big appetites and can help get the nutrients in your diet.

But the main reason to have a mass gainer protein shake is to help you build the muscle mass with a complete muscle building set of ingredients. Which they will definitely do if you weight train correctly (check out our great training guide for beginners) and eat well they will give you the extra boost to your diet to build quality muscle.

How Do Mass Gainers Work?

Mass gainers work by capitalizing on what is known as the anabolic state. The anabolic process builds muscle and is generally the body’s way of growing.

The opposite of anabolism is catabolism, or when the body eats up tissues for sustenance. When we do intense exercise, we tend to break down muscle tissue or use up a lot of our body’s nutrient stores. 

If you don’t replenish your body’s nutrients, you might enter a catabolic state or a state where the body is getting its nutrients from existing lean muscle mass, you definitely don’t want that.

You want the body to get its nutrients before this happens, thats where mass gainers drinks come in. Rather than waiting for food, get a protein drink straight in your body.

Why Do Mass Gainers Work?

When it comes to bulking, you want to replenish your body and over load your nutrient stores. This is because you want to make the most of your body’s anabolic state during and, more importantly, post exercise. When we lift heavy we break down the muscle fibres. This is what causes the muscle to grow. So Obviously we want to pack enough nutrients in to help the muscle repair fast and make them bigger. That’s whey mass gainers are one the best options to building and repairing muscle.

The best mass builders contain different digestive speed proteins to help maximize muscle recovery.They contain the BCAAs which are very important when it comes to muscle mass.Some gainers contain creatine which helps with muscle building and boost strength and creates an environment where glycogen is stored easily. We would not say absolutely essential in a mass gain due to you may want more creatine in your diet, but you can always buy a creatine supplement to add to you protein shakes or take individually.

Why Do Mass Gainers And Weight Gainers Work For Skinny Guys?

Mass gainer and weight gainers work great for skinny guys and women because they have an over load of calories, carbohydrates, protein and necessary nutrients to add and build muscle.
