The 6 Best Supplements for Muscle Growth

#1 D-Bal MAX: Best Muscle Builder Overall

Marketed as a natural alternative to steroids, D-Bal Max is our top choice for muscle gain, strength, and performance.

D-Bal MAX is a dietary supplement that bodybuilders use to maximize their workout performance. This product can create the following benefits for your body:

  • Fast muscle gains
  • Increased strength overall
  • Faster muscle recovery
  • Impressive workout performance

D-Bal MAX produces these benefits through its powerful formula of natural ingredients.

First, it helps to increase protein synthesis in your body. Protein synthesis is the process your muscles go through post-workout to restore any damaged fibers and rebuild your muscle cells stronger.

Without D-Bal MAX, your muscles may require a day or two of rest between workouts to recover from muscle soreness. However, D-Bal MAX’s ingredients increase muscle protein synthesis, allowing you to get back into the gym faster so that you can lift weights every day.

Next, this product includes ingredients that can reduce your serotonin levels. Serotonin is the primary neurotransmitter involved in sleep. When your serotonin levels are high, you experience muscle fatigue more frequently and need to take longer breaks between workouts. However, lowering serotonin levels can help improve exercise performance and reduce tiredness.

Finally, D-Bal MAX boosts the levels of two essential hormones for building muscle mass: testosterone and insulin-like growth factor (IGF-1). Testosterone contributes to muscle growth, while IGF-1 triggers the production of new, stronger muscle cells. Keeping both of these hormones high is an important factor in improving muscle strength.

D-Bal MAX contains the following natural ingredients:

  • Whey protein complex
  • Pro BCAA (branched-chain amino acids) complex
  • 20-hydroxyecdysterone (20E), a plant steroid

To experience the best results from D-Bal MAX, be sure to take three capsules each day. If you do not begin seeing impressive gains in 60 days, you can receive a full refund of your original purchase price.

We recommend D-Bal MAX for anyone looking to build muscle mass quickly and effectively through a tried-and-true natural supplement.

#2 TestoPrime: Best Supplement for Increasing Testosterone


TestoPrime is the best muscle-building supplement for men who want to increase their testosterone levels, improve their physical energy, and boost their confidence.

Testosterone is the primary male sex hormone. While this hormone plays a wide range of roles within the body, one of its main jobs is maintaining muscle mass.

Unfortunately, many men experience low testosterone at some point in their lives, often as they begin to reach middle age. According toHarvard Health Publishing, low testosterone can lead to several side effects, including loss of muscle mass.

Thankfully, TestoPrime is a natural solution for increasing testosterone levels and for beginning to up your muscle performance. This supplement can produce benefits such as:

  • Faster muscle recovery
  • Increased energy levels
  • Increased muscle strength
  • More body fat loss

TestoPrime produces these benefits through its natural ingredients that boost testosterone levels.

One of TestoPrime’s most potent ingredients is D-aspartic acid, an amino acid that contributes to the production of luteinizing hormone. This hormone helps boost testosterone levels, thus creating firmer muscles and enhancing weight loss.

Next, TestoPrime contains green tea extract, which can help to prevent testosterone from breaking down into dihydrotestosterone in the body, keeping your T-levels high as a result. Green tea extract is also high in antioxidants, so that it reduces oxidative stress and fights free radicals. Because it contains a small amount of caffeine, green tea can also boost your energy levels.

TestoPrime also contains several ingredients that target other areas of muscle gain aside from testosterone. Panax ginseng, for example, is a Chinese root that can boost your energy and prevent muscle fatigue. Additionally, fenugreek is an ancient extract that can boost your metabolism, making it easier for you to burn fat.

The TestoPrime creators carefully crafted the supplement’s formula so that it has only effective, trustworthy ingredients for muscle gain and testosterone production. This supplement includes the following ingredients:

  • D-aspartic acid
  • Fenugreek
  • Ashwagandha extract
  • Panax ginseng
  • Green tea extract
  • Zinc
  • Vitamin D
  • Pomegranate extract
  • Vitamin B6
  • Black pepper extract
  • Garlic extract
  • Vitamin B5

The TestoPrime creators recommend taking four TestoPrime capsules each morning before eating breakfast. The supplement is designed to not cause indigestion or an upset stomach, allowing you to feel confident taking them each day before your first meal.

Altogether, we recommend TestoPrime for any man looking to increase his testosterone levels and boost muscle gain naturally.

#3 CrazyBulk: Best Bulking Stack for Muscle Gain

crazybulk bulking stack

CrazyBulk is a muscle-building stack with four different supplements in one complete package.

You may have heard that pro athletes sometimes take several steroids at the same time to boost their overall muscle-synthesizing effects. However, steroids can cause a range of adverse side effects and are illegal without a prescription. If you’re looking for a stack of muscle-building supplements that can produce similar benefits to those of steroids, we recommend CrazyBulk Bulking Stack.

CrazyBulk is a leading supplement company that produces several steroid-like supplements for athletes. CrazyBulk Bulking Stack can deliver multiple benefits for your workout performance, such as:

  • Increased muscle mass
  • Boosted testosterone levels
  • Faster muscle growth
  • Increased endurance
  • Better exercise performance

This stack includes four CrazyBulk supplements for improving muscle gain: Testo-Max, Trenorol, DecaDuro, and D-Bal.

Testo-Max increases your testosterone levels through a powerful formula of D-aspartic acid, zinc, vitamin D, and several other effective components. These ingredients can stimulate luteinizing hormone, which tells your body to raise its testosterone levels.

Next, Trenorol helps your muscle tissue and muscle cells retain more nitrogen than they would naturally, allowing you to burn fat more quickly. This supplement also increases your red blood cell production, which may give you more energy during and after a workout.

Meanwhile, DecaDuro also allows your muscle cells to retain nitrogen, helping your body increase muscle mass faster. The supplement also strengthens your connective tissues, such as your ligaments and tendons, to reduce muscle soreness and joint pain post-workout.

Finally, D-Bal has several effective ingredients that contribute to muscle bulking and fat reduction. Additionally, this supplement lowers your cholesterol and increases your VO2 max, which is the maximum oxygen consumption your body can use during exercise.

Each component in the bulking stack contains a unique blend of natural ingredients. You can read more about each supplement’s formula on the CrazyBulk website.

To see the best results, follow this schedule for when to take each pill:

  • Take Testo-Max in the morning
  • Take DecaDuro and Trenorol as pre-workout supplements
  • Take D-Bal post-workout

Be sure to combine these supplements with an intense training exercise program and a healthy diet.

Overall, we recommend CrazyBulk Bulking Stack for any athlete looking to bulk up and build muscle quickly.

#4 HyperGH 14X: Best for Increasing HGH Production

hypergh 14x

HyperGH 14X is the top-rated supplement for increasing HGH levels, making it a popular choice among bodybuilders and athletes.

Human growth hormone (HGH) plays a major role in regulating body composition, bone density, cholesterol, and fat storage. Adults who have a HGH deficiency often experience higher body fat levels, fatigue, and lean body mass, all of which may make it challenging to increase muscle mass and achieve muscle gain in the gym.

If you’re looking for a way to boost HGH production, HyperGH 14X could be your perfect solution. This natural dietary supplement can provide benefits such as:

  • Faster workout recovery
  • Reduced body fat
  • Increased muscle gain
  • Higher energy levels

HyperGH 14X contains an effective formula of fifteen HGH precursors, each of which jumpstarts your HGH production and provides additional benefits for your muscles.

One of the supplement’s primary ingredients is L-arginine, an amino acid that can boost your HGH levels, improve workout performance, and build muscle tissue. Because your body does not produce L-arginine independently, you can obtain this substance only through a normal diet or a supplement like HyperGH 14X.

The supplement also contains L-glutamine, an amino acid that your body uses during times of stress and high exertion. L-glutamine helps you maintain healthy muscle tissue, increase your energy levels, and produce new muscle cell growth.

Another critical ingredient in HyperGH 14X is gamma-aminobutyric acid or GABA. This amino acid stimulates HGH production and promotes a healthy nervous system.

HyperGH 14X’s extensive ingredient list includes:

  • L-glutamine
  • L-arginine
  • L-tyrosine
  • Tribulus terrestris extract
  • L-glycine
  • L-lysine
  • GABA
  • Astragalus root extract
  • Deer antler velvet
  • Colostrum
  • Anterior pituitary powder
  • L-valine
  • GTF chromium
  • Phosphatidylcholine
  • L-ornithine

The HyperGH 14X creators recommend taking one dose of the supplement twice each day. Spreading out your doses in this way will optimize your body’s absorption of the supplement’s ingredients, creating an ideal release of HGH throughout the day. In addition, unlike other supplements, HyperGH 14X uses a special system to increase absorption by 80% to 90%.

Overall, we recommend HyperGH 14X for athletes looking to increase HGH production during muscle and strength training.

#5 TestoFuel: Best Pills for Bodybuilding


TestoFuel is one of the highest quality supplements for men who want to gain muscle, increase testosterone levels, and reduce body fat.

Bodybuilders need the right balance of protein and nutrients in their diets to maximize their strength and muscles. If you’re looking for a supplement that can help you sculpt a defined physique while increasing muscle mass, TestoFuel is an excellent option to consider.

TestoFuel is a natural supplement that aims to increase low testosterone levels and was developed with bodybuilders in mind. Taking this supplement each day can produce benefits such as:

  • Increased muscle growth
  • Boosted strength
  • Reduced body fat
  • Improved mood and self-esteem

The TestoFuel creators know how challenging increasing your muscle mass can be, even when you regularly participate in strength training and high-intensity exercise. The company created this supplement to help athletes achieve faster muscle gains and see the evidence of their hard work in the gym.

One of the primary ways that TestoFuel helps bodybuilders is by stimulating testosterone production. The supplement contains several ingredients that can raise your T-levels, including D-aspartic acid, vitamin D, and others.

Increasing your T-levels can speed up protein synthesis in your body, allowing you to gain muscle mass more efficiently. Testosterone may also limit the effects of the catabolic hormone cortisol in your body, reducing muscle breakdown.

TestoFuel also contains ingredients that target other areas of muscle gain. For example, ginseng, a primary contributor to the TestoFuel formula, can boost muscle mass by increasing nitric acid levels in your blood. This ingredient also enhances your insulin sensitivity, allowing you to shed excess body weight and fat faster.

Additionally, TestoFuel contains an effective dose of magnesium. This mineral can regulate the enzymes within your body, increases your energy levels, and promotes faster muscle recovery from a challenging exercise program.

TestoFuel contains the following natural ingredients:

  • Oyster extract
  • Vitamin D3
  • Fenugreek seed
  • Vitamin K2
  • Asian red panax ginseng
  • Vitamin B6
  • D-aspartic acid
  • Magnesium
  • Zinc

To experience the best results from TestoFuel, be sure to take four capsules each day. The creators recommend taking the supplement for at least two months to see the most benefits.

All in all, we recommend TestoFuel for bodybuilders looking to improve their muscle gain by boosting testosterone production.

#6 PrimeShred: Natural Bodybuilding Supplement


PrimeShred is one of the most effective supplements for increasing muscle mass while shredding fat.

Burning excess fat is an essential step in building stronger, bigger muscles. However, getting rid of stubborn fat can be challenging, even if you are eating healthily and working out each day. One way to aid your fat-burning processes is to take a supplement with special ingredients that help you to shed body fat faster.

PrimeShred is a dietary supplement that can help you achieve the lean, muscular body of your dreams. Taking this supplement can produce benefits such as:

  • Faster whole-body fat burning
  • More energy to complete workouts
  • Better focus and mental clarity
  • Improved mood

PrimeShred produces these benefits by boosting your body’s fat-burning processes, allowing you to burn fat faster and more efficiently.

One way PrimeShred helps you burn fat is by increasing the release of norepinephrine and epinephrine in your body. These hormones trigger lipolysis, or fat breakdown, which can enable you to burn more fat than you could through diet and exercise alone. Several of PrimeShred’s ingredients, such as L-tyrosine, green tea, and the capsaicin in the cayenne pepper, increase the production of norepinephrine and epinephrine.

Next, PrimeShred can help reduce belly fat by boosting lipase levels in the abdomen. Lipase is an enzyme that breaks fat down into glycerol and fatty acids. As a result, increasing your lipase level tells your body to burn more fat.

Additionally, PrimeShred contains several ingredients that increase your adiponectin levels, another hormone that boosts the fat-burning processes. Caffeine, green tea, and green coffee each increase adiponectin.

Finally, PrimeShred contains several ingredients that can give you an energy boost and mayl help you to complete intense workouts. The supplement’s formula includes pure caffeine, along with green coffee and green tea, which each contain small amounts of caffeine. Additionally, PrimeShred includes L-theanine, which enhances the effects of caffeine within the body.

Altogether, PrimeShred’s ingredient list includes the following:

  • DMAE
  • Green tea extract
  • Green coffee
  • L-tyrosine
  • L-theanine
  • Vitamin B complex
  • Bioperine
  • Rhodiola rosea root
  • Caffeine anhydrous
  • Cayenne pepper

PrimeShred packs all of these ingredients into a vegetable capsule suitable for vegetarians and vegans.

To see the best results, plan to take three capsules daily about 20 minutes before eating breakfast. Be sure to take these capsules every day, whether you plan to work out that day or not.

Overall, we recommend PrimeShred for anyone looking to boost their fat-burning processes to lose weight and build muscle.

Additional Muscle-Building Supplements to Consider

Some athletes choose to supplement their diets with specific proteins, amino acids, and compounds to promote targeted effects for their muscles. These supplements contain a less diverse range of ingredients compared to the products we reviewed above. Still, their effects are more specialized, allowing athletes to choose a few different supplement options to target their needs more precisely.

Here are a few popular supplements that produce more specialized effects for your strength training goals.

Whey Protein

If you’ve been weight training for long, you probably know that your protein intake is essential for building muscle mass and increasing strength. However, you may not realize that some protein sources are better than others.

Whey protein is one of the most beneficial protein sources for building strength and muscle. It is a combination of proteins from whey, which is the liquid in dairy products.

Athletes often take whey protein supplements because the protein has numerous effects on weight training. Whey protein promises to:

  • Increases muscle growth
  • Releases anabolic hormones
  • Stimulates protein synthesis
  • Is absorbed faster than other protein sources

If you’re having trouble consuming enough protein in your diet to give an increase in muscle mass, taking whey protein supplements or whey protein powder may give you the boost you need.
