Review of the Best Muscle Growth Supplements of 2025
#1. D-Bal Max: Best Supplement for Bodybuilding and Natural Muscle Growth
D-Bal Max is a popular bodybuilding supplement that mimics the effects of the anabolic steroid Dianabol. Taking the steroid Dianabol can lead to dangerous side effects ranging from heart disease to liver damage, which is why many athletes turn to safer alternatives - like D-Bal Max - instead.
Benefits
Taking D-Bal Max can lead to benefits such as:
Faster muscle growth
Streamlined exercise recovery
Amplified muscle strength and power
Increased energy and stamina
Faster fat burning
Formula Overview
D-Bal Max contains a blend of natural ingredients. The formula includes the following:
Vitamin C
Magnesium
Vitamin B6
Zinc
Vitamin B9
Copper
L-arginine HCL
Ashwagandha
L-Lysine HCL
SENACTIV®
Caffeine
Magnesium is one of the primary ingredients in the formula and plays an important role in building muscle. Low levels of magnesium in the body can lead to symptoms like muscle cramping and weakness.
The formula also includes ingredients that boost immunity, such as vitamin C and zinc. While these vitamins can help you stay healthy, they also impact your ability to build muscle. Zinc also helps your body produce testosterone and human growth hormone, which both contribute to muscle building.
The formula contains two amino acids: L-arginine and L-lysine. L-arginine is a precursor to nitric oxide and can speed up your body's release of growth hormone. L-lysine, when combined with L-arginine, promotes growth hormone secretion and aids muscle recovery.
Each dose of D-Bal Max also includes 200 mg of caffeine, which is equivalent to about two cups of coffee. This dosage can help you stay alert and energized as you adjust to tougher workouts, but it shouldn't give you the jitters.
SENACTIV® is a patented ingredient that contains a blend of Panax notoginseng and Rosa roxburghii. This compound helps fight inflammation in the muscles and gives you the energy to complete tough gym sessions.
What We Like Most
We appreciate that the D-Bal Max creators offer a 100% satisfaction guarantee on all supplement orders. The company's 60-day money-back guarantee enables you to try D-Bal Max for two full months without a monetary commitment. If the supplement isn't right for you, you can return your unused capsules for a refund of your purchase price.
The D-Bal Max formula is clean and natural, containing no soy or gluten and only including natural ingredients. The company manufactures this supplement in the U.S. and backs its formula with scientific research.
Who Is This Product Best For?
We recommend this product to anyone looking to amplify muscle growth. If you're a bodybuilder or simply trying to build strength, D-Bal Max is a reliable supplement to help you achieve your goals.

#2.Testo-Max: Most Effective Muscle Builder for Increasing Testosterone
Men experience decreasing testosterone levels as they age, which can impact their ability to build muscle, lose weight, and even perform in the bedroom. While significant deficits may require prescription medication, most men can benefit from the subtle testosterone boost that comes with a formula like Testo-Max.
Benefits
Taking Testo-Max can produce the following benefits:
Increased testosterone levels
More energy and motivation
Increased muscle growth and strength
Faster fat loss and a leaner appearance
Formula Overview
Testo-Max contains a blend of 11 ingredients:
D-aspartic acid
Fenugreek
Zinc
Vitamin K1
Boron
Magnesium
Korean Red Ginseng
Nettle Leaf Extract
Vitamin D3
Vitamin B6
BioPerine
While all of these ingredients contribute to the supplement's testosterone-boosting effects, one of the most powerful is D-aspartic acid.
D-aspartic acid is a natural amino acid regulator that stimulates your body's production of luteinizing hormone (LH). LH directly increases your testosterone levels. So taking a supplement with D-aspartic acid is one of the most straightforward ways to increase testosterone production.
Zinc is another ingredient that directly supports testosterone levels. This mineral slows down your body's conversion of testosterone into estradiol, giving you access to more free testosterone to increase muscle mass and libido.
Nettle leaf extract is a plant extract that may support testosterone production and provide several other benefits for your athletic performance. This extract contains antioxidant-rich polyphenols, which can help you regulate your blood sugar levels, reduce stress, and streamline weight loss efforts.
Like other supplements for muscle growth on our list, Testo-Max contains magnesium to support several aspects of a healthy lifestyle: boosting metabolism, supporting muscle protein synthesis, increasing energy, and balancing electrolytes.
What We Like Most
CrazyBulk, the creator of Testo-Max, is a well-known supplement company that produces several steroid alternatives and muscle-builder supplements. The company offers a 60-day money-back guarantee that enables you to try its supplements without a monetary commitment.
CrazyBulk wants to support your weight loss and muscle-building efforts beyond simply creating great products. The company also includes two free e-books with every Testo-Max purchase - the Hypertrophy Workout Plan e-book and the 5x5 Workout Plan e-book.
Who Is This Product Best For?
Testo-Max is a great solution for men looking to increase their testosterone levels naturally. This testosterone booster contains several key ingredients that directly support T-levels and other aspects of muscle-building, allowing you to see comprehensive results.

#3. CrazyBulk Bulking Stack: Best Muscle-Building Stack
Sometimes, taking one muscle-building supplement isn't powerful enough to produce your desired results. If you're serious about bulking up and building muscle, you may want to consider a bulking stack - like the one from CrazyBulk.
Benefits
The CrazyBulk bulking stack can produce benefits such as:
Fast muscle growth
Boosted muscle mass
Rapid exercise recovery
Formula Overview
This bulking stack consists of four CrazyBulk supplements:
D-Bal, a legal alternative to Dianabol
Testo-Max, a legal alternative to Sustanon
DecaDuro, a legal alternative to Deca-Durabolin
Trenorol, a legal alternative to Trenbolone
You can explore the full ingredient lists for each of these muscle-building supplements on the Crazy Bulk website. We'll highlight one key ingredient for each supplement.
First, D-Bal contains a new formula that is seven times stronger than the previous version. One of the most powerful new ingredients is ashwagandha, a plant extract that increases your VO2 max. This measure is the maximum amount of oxygen you can take in while exercising.
As we discussed above, Testo-Max contains several key ingredients, one of which is the amino acid regulator D-aspartic acid. This ingredient stimulates the luteinizing hormone to produce more testosterone.
DecaDuro contains three amino acids - L-arginine, L-carnitine, and L-citrulline - that boost nitrogen production and collagen synthesis. Nitrogen helps your body build muscle, and collagen helps strengthen the ligaments and connective tissues, reducing muscle fatigue.
Trenorol contains beta-sitosterol, which helps balance testosterone levels and may support muscle growth and strength.
What We Like Most
Stacking supplements for muscle growth can be effective, but you must understand which supplements you can safely take together. You don't want to overlap ingredients or accidentally overdose on an amino acid or mineral.
With the CrazyBulk bulking stack, you can feel confident that you will only ingest safe, effective levels of each ingredient. CrazyBulk also explains the best way to take this stack:
Take Testo-Max every morning
Take DecaDuro and Trenorol before your daily workout
Take D-Bal after your workout
Sticking to this schedule helps you gain the appropriate benefits of each supplement at specific times of the day.
Who Is This Product Best For?
We recommend the CrazyBulk bulking stack for anyone who has tried muscle-building supplements in the past without success. Stacking these four effective supplements may produce more noticeable results for your muscle growth and lean muscle mass.

#4. HyperGH 14X: Powerful Muscle Enhancer for Increasing HGH Levels
Human growth hormone (HGH) is a naturally occurring hormone that impacts many aspects of your physical fitness, including muscle growth.
While your HGH levels can naturally decline with age, you can restore them to their previously elevated levels with a supplement like HyperGH 14x.
Benefits
Taking HyperGH 14x can produce benefits like:
Faster recovery times
Rapid muscle growth
Lower body fat composition
Better sleep habits
Formula Overview
HyperGH 14x packs in 15 natural ingredients that include over 4,000 mg of HGH precursors in each daily dose. The full ingredient list includes:
L-arginine
L-glycine
L-tyrosine
L-glutamine
L-lysine
Tribulus Terrestris
Deer antler velvet
Astragalus root extract
GABA
L-valine
Colostrum
Anterior pituitary powder
L-ornithine
Phosphatidylcholine
GTF chromium
The formula includes seven amino acids - all of the ingredients starting with "L-" - that stimulate muscle protein synthesis and supply your body with nitrogen. It includes both essential amino acids - ones your body does not produce on its own - and non-essential amino acids - ones your body can produce, but that you may not get enough of through diet alone.
L-arginine is a non-essential amino acid you'll often see in workout supplements. This ingredient may increase your growth hormone levels by as much as triple their current levels. It can also aid fat burning, help you build healthy muscle tissue and muscle fibers, enhance male fertility, and boost your immunity.
L-glutamine plays a role in metabolism and maintaining muscle growth. Your body uses this substance during times of stress, and having a healthy supply can help you manage physically demanding processes, like building muscle mass, better.
Outside its amino acid content, HyperGH 14x also contains extracts like deer antler velvet, which is high in insulin-like growth factor (IGF-1). This component plays an essential role in your body's natural production of HGH.
What We Like Most
This supplement takes a few measures to boost your body's absorption and usage of its natural ingredients. It uses a twice-daily dose - one in the morning and one before bed - to optimize the times your body releases HGH. It also has a pharmaceutical-grade enteric coating that may increase your body's absorption of its ingredients by 80% to 90%.
HyperGH 14x comes with a generous 60-day money-back guarantee. You can return two empty boxes and as many unopened boxes of HyperGH14x as you want within 60 days of the purchase date for a full refund, minus shipping charges.
The company produces its bodybuilding supplements in an FDA-compliant and GMP-certified facility. You can feel confident that these pills are safe and effective.
Who Is This Product Best For?
We recommend HyperGH 14x for anyone looking to increase their human growth hormone levels naturally while specifically targeting muscle tissue and lean muscle growth. This supplement contains the right blend of ingredients to stimulate muscle protein synthesis throughout the day.

#5. CRN-5: Best Creatine for Muscle Growth
Creatine is an amino acid your body uses to increase muscle mass and improve exercise performance. If you're looking for the best pre-workout supplements with creatine, we recommend CRN-5 from CrazyNutrition.
Benefits
Taking CRN-5 can produce benefits like:
Maximize strength
Intensify workouts
Preserve muscle gains
Speed up exercise recovery
Increase focus
Formula Overview
CRN-5 contains five creatines and essential electrolyte ingredients that support healthy muscle growth. The ingredient list includes:
Creatine monohydrate
Creatine ethyl ester
Creatine hydrochloride (HCL)
Tri-creatine malate
Creatine citrate pyruvate
Aquamin MG
Sodium
Potassium
Creatine monohydrate is a common ingredient in creatine supplements. This form of creatine helps support the natural production of phosphocreatine in the muscles, which can prevent muscle breakdown and help maximize muscle gains. Creatine monohydrate may also help the muscle cells produce more energy.
To help you gain muscle faster, CRN-5 contains creatine hydrochloride, which your body can absorb and utilize more quickly than creatine monohydrate. Similarly, tri-creatine malate is water soluble, which maximizes absorption and minimizes bloating when you take it.
Creatine ethyl ester is another popular form of creatine in supplements for muscle growth. This ingredient is effective in small doses and can penetrate the muscle cells faster than other forms of creatine. It produces rapid muscle growth and strength.
This supplement contains sodium to help you maintain an electrolyte balance. At healthy levels, sodium is essential for muscle, cell, and nerve function and for maintaining adequate hydration.
Potassium has similar effects - it can help you maintain endurance, energy, and hydration through intense workouts. It can also aid muscle recovery.
What We Like Most
CRN-5 packs in five powerful creatine forms to give your body the best chance of increasing its creatine supply. Including a mix of different creatines instead of one higher dose of a single creatine can help prevent a creatine tolerance from forming over time.
We appreciate that this supplement also focuses on muscle hydration through its addition of electrolytes, giving your body the essential components for muscle gain.
CRN-5 comes in two delicious flavors - lemon-lime and orange-mango - and actually tastes good, so you won't have to force it down. Unlike some creatine supplements, CRN-5 shouldn't cause any bloating or gas.
Who Is This Product Best For?
We highly recommend CRN-5 as one of the best creatine supplements on the market. If you're looking for an effective way to boost muscle strength and recovery, taking a well-rounded creatine supplement like CRN-5 can produce effective results.

#6. CrazyBulk Mass Gainer: Best Mass Gainer for Fast Muscle Growth
Mass Gainer is a protein powder supplement from CrazyNutrition, the sister company of CrazyBulk. It can help you pack on muscle gain quickly and with minimal bloating.
Benefits
Taking the Mass Gainer pre-workout supplement can produce benefits like:
Rapid muscle growth
Faster muscle recovery
More lean body mass without the additional fat
Formula Overview
Mass Gainer contains only whole-food-sourced ingredients without any fillers or maltodextrin. This muscle supplement includes the following ingredients:
Gluten-free oat flour
Whey protein blend
MCT oil
Vitamin B6
Vitamin B12
Zinc
Magnesium
Digezyme
Gluten-free oat flour contains complex carbohydrates that can support healthy blood sugar levels, boost muscle gain, give you a feeling of fullness, and improve your digestion. This ingredient is the foundation of the Mass Gainer formula.
Mass Gainer also contains MCT oil, which is an ingredient distilled from coconut oil that is popular among people following a keto diet. This supplement is low in carbohydrates and high in beneficial fats. It can improve your gut health, help you convert fatty acids into energy, and fuel intense workouts.
Mass Gainer's whey protein blend contains a combination of whey protein and milk, providing 40 grams of protein in each dose. It also contains a diverse amino acid profile that targets muscle protein synthesis.
Digezyme is Mass Gainer's blend of five enzymes that target absorption and digestion. With this ingredient, your body can absorb the whey protein powder and other ingredients in the Mass Gainer formula faster and with minimal bloating. This blend may also reduce muscle soreness.
Zinc and magnesium both play important roles in protein synthesis and can help with increasing muscle mass and strength. They can also help you fight fatigue and sickness as you adjust to an intense workout regimen.
What We Like Most
Whey protein powder has a reputation for tasting bad and being hard to get down, but Mass Gainer overcomes this reputation by combining its whey protein isolate with digestion-supporting and delicious ingredients. Mass Gainer comes in tasty vanilla and chocolate flavors that are easy to mix with water or any other liquid.
When you order Mass Gainer, you'll also receive a free lifetime subscription to Muscle and Health Magazine, which can help you stay up to date with the latest breakthroughs in the science of muscle growth.
Like other supplements for muscle growth on our list, Mass Gainer comes with a 60-day money-back guarantee that allows you to try the product risk-free.

How to Choose The Best Supplements for Muscle Gain
The six best muscle-building supplements above are only a few of the hundreds of related supplements available on the market. At a glance, it can be challenging to determine which pre-workout supplements are actually safe and effective and which could be a scam.
If you decide to look for workout supplements outside this list, we recommend choosing an option that meets the following criteria:
Natural Ingredients
The best muscle-building supplements should only contain natural ingredients that you can get without a prescription. If you find a supplement that contains actual drugs and is being sold online or over the counter, you cannot trust that it is safe.
Many supplements for muscle growth produce similar effects to anabolic steroids, so their creators call them "steroid alternatives." Even if a company compares its supplements to steroids, these products should not contain any actual drugs or harsh ingredients.
Supplement companies should also be transparent about the ingredients in their formulas. If you have to search high and low to find a supplement's ingredient list, the company probably has something to hide - whether that's low-quality ingredients or potentially unsafe ones.
Good Manufacturing Practices
The FDA does not regulate the production of dietary supplements, so you'll need to exercise due diligence to determine that a supplement is safe and reliable. One way is to examine a supplement company's manufacturing practices.
Many manufacturers produce their supplements in Good Manufacturing Practices (GMP) certified facilities. You should also look for companies that use third-party testing to ensure that their supplements contain formulas that accurately reflect their labels.
Positive Customer Reviews
Many supplement companies post customer reviews on their websites, but you cannot always assume that these reviews are accurate. Instead, we recommend looking for reviews of a product on third-party platforms like Google My Business, the Better Business Bureau, and Amazon.
Make sure you sort the customer reviews by "most recent" instead of "top" to get a balanced mix of positive and negative reviews. While you can expect every dietary supplement to have some negative reviews, the best supplements for muscle growth have overwhelmingly positive ones.
Reviews can also help you have realistic expectations as you try a new pre-workout supplement. If most users say a supplement took several weeks to begin working, you can better predict your own experience with the supplement.
Money-Back Guarantee
Trying a new supplement is an investment, as you really need to test a supplement for at least 60 days before determining whether it is right for you. However, the best muscle-building pills come with money-back guarantees to lower your risk.
Money-back guarantees enable you to return your unused capsules for a full refund of your purchase price. Most of the supplements on our list come with 60-day money-back guarantees, which allow you to try the product for a significant amount of time to truly understand its effectiveness.
Companies that offer money-back guarantees know that most customers will like their products. If they didn't, they wouldn't take such a big risk by offering full refunds on products they can't resell.
Types of Muscle-Building Supplements
Different types of muscle-building supplements target different aspects of muscle growth, like supplementing your protein intake, providing you with essential amino acids, increasing your testosterone or growth hormone, or supporting your creatine production. Understanding the differences between these types of supplements can help you choose the right one for your needs.
Pre-Workout Supplements
Pre-workout supplements can enhance athletic performance, which is why you should take them within an hour before your workout. These supplements typically contain ingredients like caffeine that can energize you. They may also contain ingredients such as:
Creatine
Beta-alanine
Nitric oxide precursors
Branched-chain amino acids
Beta-alanine and branched-chain amino acids are both amino acids that can support muscle mass and reduce muscle fatigue.
Beta-alanine may aid your body's production of carnosine, a compound that can boost your endurance and help your muscle fibers contract with more force. Branched-chain amino acids are the fuel your muscles burn for energy.
Meanwhile, nitric oxide precursors support your body's ability to produce nitric oxide, which is an essential component of muscle growth.
Many athletes pair pre-workouts with post-workout supplements that aid workout recovery. If you do this, just make sure that the two supplements do not contain overlapping ingredients that could produce side effects in ultra-high doses.
Testosterone Boosters
If you're over the age of 40, adding a testosterone booster to your supplement regimen can make a world of difference. Testosterone plays a role in a wide range of physical functions, including sex drive, muscle growth, fat loss, energy, and even mental health.
Testosterone boosters typically contain D-aspartic acid, which stimulates the luteinizing hormone in the testes to increase testosterone production. Along with boosting testosterone, these supplements also typically promote muscle growth and may help you burn fat, among other benefits.
Protein Shakes
If you're trying to bulk up, increasing your protein intake is essential. Amino acids, the building blocks of protein, help repair muscle cells and maintain muscle tissue.
Protein supplements and shakes can aid with building muscle mass by giving your body access to plenty of protein to keep your muscles healthy. Whey protein isolate is a popular ingredient in protein powder because it is affordable and has a pleasant taste. It's also considered a complete protein, meaning it has all nine types of essential amino acids.
Whey protein supplements usually come in the form of protein powder instead of as capsules or pills. You should mix the correct dose of protein powder with a liquid, such as water, milk, or a smoothie, and drink the entire dose.
Anabolic Supplements
Anabolic supplements are legal steroid alternatives that produce similar results to anabolic steroids - without the harsh side effects.
CrazyBulk is a popular manufacturer of these steroid alternatives. The bulking stack above consists of four anabolic supplements that include comprehensive blends of natural ingredients to help you gain muscle.
While anabolic supplements aren't nearly as powerful as actual steroids, they target similar areas of the body. Because anabolic steroids are illegal, unsafe, and expensive, many athletes turn to these natural alternatives instead.
Creatine
Creatine is an amino acid found in the muscle tissue and the brain. This substance helps produce energy for your muscles, and while your body produces it naturally, you may not get enough from a normal diet. Taking a creatine muscle growth supplement can ensure that your body has access to plenty of this energizing substance.
Creatine amino acid supplements are most effective for high-intensity interval training (HIIT) and exercises like weight lifting and cardio.
Frequently Asked Questions about Muscle Mass Supplements
What is the best muscle-building supplement for women?
While most of the supplements above are suitable for women (aside from Testo-Max), we recommend CRN-5 as the best option. This creatine supplement includes a diverse range of creatines to prevent you from building up a tolerance.
How can I get the best results with muscle supplements?
Even the best supplement for muscle growth are not magic pills that will instantly grow your muscles. Instead, these supplements work best when you combine them with a healthy diet and exercise regimen.
If you're trying to build muscle and body weight without gaining fat, you'll want to stick to a healthy diet with lots of protein-rich foods, fruits and vegetables, and whole grains. Cut down your fat, sugar, and salt intake and stay hydrated throughout the day. (The general rule is to drink half your weight in ounces of water each day.)
If you're hoping to gain muscle in a certain area of your body, such as your triceps and biceps, you'll still want to exercise all of your muscles. We recommend at least four workout days a week.
How long does it take to see results with muscle-building pills?
The best supplements for muscle growth begin producing some results within six weeks of use. You'll see the best results after two continuous months of taking a new supplement, however.
Muscle and protein supplements take time to begin regulating your amino acids and nutrient levels, so you can't expect to see instant results. That's why many supplement companies offer a 60-day money-back guarantee, which allows you to try their supplements for the recommended time before making a decision about their effectiveness.
Once you stop taking muscle gain supplements, their benefits will cease. As a result, it's important to continue taking these supplements throughout your muscle-building journey. If you have trouble avoiding muscle breakdown, you may want to keep taking these dietary supplements for a few months after you meet your goals.
Are muscle enhancers safe to take?
Muscle-building supplements are generally safe for most people. The best supplements for muscle growth on our list contain only natural ingredients in safe dosages. You likely won't experience any adverse side effects from these products.
If you have any health concerns or are currently taking other supplements, talk to your doctor before adding a muscle growth supplement to your regimen. If you do experience adverse effects, stop taking the supplement and consult your doctor.
