The world of muscle supplements has exploded in recent years, especially as people have looked for alternatives to traditional steroids. Let’s take a look at CrazyBulk, one of the most well-known muscle growth supplement companies on the Internet, and see how their offerings measure up.

What is CrazyBulk?

Put simply, CrazyBulk is a muscle supplement company that provides “steroid alternatives” in the form of capsules primarily made from natural ingredients. While these aren’t true steroids per se, they are very similar even though they don’t require injections or any other intake method besides consumption of capsules.

Their supplements mimic the effects of real steroids and reportedly don’t include many of the harmful side effects that pro athletes suffer from when they use such enhancements. They’ve become incredibly popular over the last few years because they allow bodybuilders and athletes to boost their muscle growth rate and appearance without any of the legal ramifications that come with using regular steroids.

CrazyBulk has a broad catalog of steroid alternatives, selling capsules that can:

  • Improve your muscle gain (bulking)
  • Enhancing your muscle appearance (cutting)
  • Improving actual strength gain
  • Preventing your muscles from degrading as you age
  • Boosting your testosterone, which comes with a plethora of possibly helpful side effects

CrazyBulk was initially founded in 2014 and has since improved its offerings and updated them as new science and ingredients have become available.

While genuine steroids are more powerful than the alternatives that CrazyBulk sells, they are almost entirely illegal and come with many negative side effects.

Why Are Steroids Harmful?

Anabolic steroids (which are the kind of people usually mean when they say steroids) are almost always merely synthetic variations of the core hormone testosterone. Testosterone is the primary male sex hormone, although both men and women produce it in varying amounts. Testosterone is not only good for helping you to build muscle but also regulates many of your body’s basic functions and helps you live a healthy life.

Steroids were initially developed specifically to boost testosterone in certain people with hormone deficiencies.

But steroids can be harmful precisely because testosterone is an incredibly powerful hormone and it affects a variety of bodily processes. Strictly speaking, scientists aren’t 100% sure why steroid injections cause such negative side effects in many of their users. But the bad symptoms that come in conjunction with regular steroid use are well known and include:

  • Infertility in men and women
  • Painful erections in men
  • The development of breasts in men
  • Lower sperm count for men
  • Testicular shrinkage for men
  • Impotence for men
  • Growth of body hair for women
  • Voice deepening for women
  • Reduced breast size for women
  • Increased acne for both sexes
  • Increased skin oil for both sexes
  • Yellowing of the skin
  • Heart enlargement
  • Increased risk for liver disease and cancer
  • Increased risk for high cholesterol
  • Potential for violent mood swings

Perhaps most worriedly, using steroids can shut down your body’s natural production of testosterone by up to 70%. This can have lasting side effects once you stop taking the steroids and requires you to adhere to a “post cycle therapy” regimen to boost natural testosterone production and repair your body.

As you can see, it’s no surprise that regular steroid use is outlawed by most governments in the developed world. They are also strictly illegal for all official sports competitions; this is to prevent athletes with more money or resources from gaining unfair advantages over their competitors.

How is CrazyBulk Different?

CrazyBulk’s product line uses natural ingredients and the science of chemistry to create supplements that provide many of the same advantages as regular steroids without pumping you full of artificial hormones.

Naturally, these ingredient combinations can’t replicate the intense power of a true testosterone injection. But they can increase your body’s rate of protein synthesis, as well as put your body into a natural anabolic state. In other words, you’ll build muscle more quickly and keep the muscle you put on even once you stop taking the supplements.

Because of this enhancement method, you avoid the negative side effects that come with taking synthetic testosterone. In addition, you’ll avoid the post steroid therapy needed to make your body produce testosterone again.

What Does CrazyBulk Offer?

CrazyBulk offers two main collections of muscle supplements. The product collections are each developed for different bodybuilding goals, although the products within both lines do not need to be taken together and can be mixed and matched as you desire. Some products are also good for more than one use, like bulking and cutting.

Let’s check out each product that CrazyBulk offers and see what is inside every bottle.

For Bulking

CrazyBulk products designed for bulking will contain a high number of amino acids and other natural ingredients that directly influence muscle growth and preservation. These products are what you’ll want to target if you need to pack on extra muscle and improve your strength directly.


D-Bal is one of the flagship CrazyBulk products and is a direct alternative to the steroid Dianabol. D-Bal’s primary purpose is to boost muscle production between two or three times faster than you normally would. Its primary ingredient is called Suma, a compound that contains the anabolic agents class Ecdysteroids.

You might think that these are the same thing as regular anabolic steroids, but they don’t come from the same source. Instead of being synthetic testosterone, Ecdysteroids are derived from the root of the Suma plant. As a result, products with Suma are banned by some athletic commissions and allowed in others.

D-Bal also includes several strong vitamins and minerals, like Vitamin D3 and sodium hyaluronate.

If you’re an athlete looking to use this product to boost your muscle gain, check with your sport’s athletic commissions board before purchasing this supplement.


Trenorol is a direct alternative to the anabolic steroid Trenbolone, which gained notoriety in the bodybuilding world as many muscle men used it to bulk up at incredible rates. This supplement, instead of attacking you with a bunch of negative side effects, still boosts protein synthesis in your body to help you pack on muscle fast.

As a plus side, it also prevents water retention. Stopping water retention is one of the best ways you can look absolutely shredded when you’re at the gym or during a bodybuilding competition. In this way, Trenorol is a great cutting supplement, as well.

This supplement has ingredients like nettle leaves, peptin, and samento bark, which boosts your muscle gain tremendously for a natural ingredient.


Like the other supplements we’ve looked at so far, Anadrole is a direct alternative to a steroid as well: this time, it’s Anadrol. The steroid variant of the supplement was created primarily to preserve muscle mass and assist bedbound hospital patients.

Anadrole, on the other hand, is much safer than any steroid. Its primary ingredient is Acetyl-L-Carnitine, and amino acid that’s responsible for repairing your muscles and improving their growth. This amino acid is one of the most effective across muscle building supplements, so this pick is another good choice for bulking up.

It’s also bolstered with soy protein isolate and whey protein concentrate, natural compounds that increase your body’s testosterone production instead of pumping you full of synthetic hormones. This is a safer way to improve your testosterone levels without all the side effects.


DecaDuro isn’t a direct alternative to a single steroid, but it’s very similar in effect to Deca Durabolin, which is a steroid that gained notoriety among bodybuilders for its muscle-building boosts.

DecaDuro isn’t as drastic as the real steroid, of course, but it allows you to pack on more muscle at a faster rate thanks to amino acids and other natural ingredients contained within the formula. It’s one of the better choices for packing on pure muscle all over, although it doesn’t do anything for water retention.

It includes ingredients like wild yam, ginseng, and L-arginine.

For Cutting

CrazyBulk products designed for cutting may have some ancillary benefits when it comes to building muscle. But their primary purpose is to help you burn fat or lower water retention. Both effects will make your muscles pop much more dramatically, making you look leaner and more muscular at the same time.


Clenbutrol is a direct alternative to the steroid Clenbuterol: this particular steroid is well known for being abused by Hollywood celebrities and bodybuilders trying to cut down on body fat fast. However, Clenbutrol is a safer alternative that combines several products to provide multiple benefits.

For starters, it includes capsaicin as a primary ingredient. This compound will help your body burn fat more efficiently, so every mile you run is that much more effective. It’s also made with InnoSlim, which is a new synthetic ingredient that boosts your metabolic rate. In other words, it also helps your body burn through fat and calories more quickly.

It also comes with several energy-boosting ingredients and appetite reducers, like vitamin D3, bitter orange extract, and guarana extract. It’ll give you the energy you need to finish your work out and keep going throughout the day without eating as much. All in all, it’s particularly effective for those who are a little overweight and who want to maximize their body’s calorie-burning capabilities.


Anvarol was created as a response to the steroid Anavar, which originally began as a muscle preservative stimulant much like Anadrol.

So how does the supplement Anvarol help you when it comes to cutting? It helps by stopping your body from burning through muscle as you work out, allowing you to retain the shape and muscle mass you’ve already put on. As a result, it’s a great choice if you’re already fairly slim or lean and want to burn away the fat that remains without eating through the muscle you’ve worked hard to grow.

Basically, when your body burns through calories and fuel when you work out, it doesn’t always chew through fat specifically. Sometimes its natural inclination is to use muscle cells for fuel instead. Supplements like this one preserve your muscle and direct your body to burn fat instead.

Avarol causes your cells to make more ATP, the primary energy unit on the cellular scale, using ingredients like soy protein and whey protein.


Winsol is CrazyBulk’s answer to the steroid Winstrol, which is another muscle preservative with the standard plethora of steroid side effects. Winsol does a great job as well without all of the negative downsides, as well as providing you with several other health benefits thanks to its natural ingredients list.

Winsol can also improve your stamina overall, making it a great choice for cardio fanatics or gym-goers who want to improve their running endurance. It contains several natural ingredients that can boost your muscle endurance overall, though you’ll still need to practice before you can run a marathon!

Other Products

CrazyBulk also offers a handful of additional products that provide ancillary benefits without specifically boosting your bulking or cutting performance. These can be taken in conjunction with many of the other products to either enhance their effects or specifically for their advantages.


Testomax, if you couldn’t guess from the name, is a testosterone booster. Unlike synthetic testosterone like you’ll get from regular steroids, you won’t receive the negative side effects and can still see almost immediate improvements.

Low testosterone is a condition that affects lots of men, especially as they age and their body slows down. This can be particularly bad for guys since low testosterone can change their sex drive, how well they build muscle, and their overall energy levels. It’s not just athletes and bodybuilders that may want a testosterone boost.

Testomax is an alternative to the steroid Sustanon, which is a steroid usually prescribed by medical professionals in very small doses.

You can take Testomax without worrying about issues, though. It has several amino acids, plus other ingredients like ZMA and D-Aspartic, both of which have been proven to increase testosterone production naturally.

Because of this general benefit, you can take Testomax with many of the other supplements that CrazyBulk offers and see improvements for their benefits as well as all-around improvements if you suffer from low testosterone. It’s one of the best products that CrazyBulk provides for men, period.


HGH-X2 is a direct alternative to regular HGH, or the human growth hormone. This hormone is well studied in the medical world and is one of the primary hormones used in antiaging treatments, such as creams, injections, and other solutions. The human growth hormone reportedly repairs cell degradation and can even help you burn fat.

The only trouble is that regular human growth hormone is really expensive in its pure variety and is usually only acquirable through a medical prescription. It’s also directly illegal in many places, and especially for many sports commission boards.

So HGH-X2 is a more affordable and legal alternative. It’s primarily composed of the compound Somatropin, which acts to trigger your brain’s pituitary gland to release more HGH normally. This way, you don’t fill your body with synthetic HGH and instead get the real stuff from your brain.

Because of this, HGH-X2 arguably works just as well as regular HGH injections that there is no difference between the hormones you’d get either way. You’ll see improvements to your muscle growth and protein production, as well as better fat burning during your cardio sessions. You also may see several ancillary benefits like decreasing age lines on your face and skin, though this effect can vary greatly from person to person.


NO2-Max is the final CrazyBulk product they offer as a direct supplement. It’s a workout enhancer that opens your blood vessels prior to your workout, allowing any exercise you do afterward to be even more effective than it already would be.

In a nutshell, opening the blood vessels increases blood flow to and from your muscles, which allows them to get more fresh oxygen with every breath you take. You’ll also feel that your muscles don’t get as tired or burn as intensely because of the increased blood flow. Men with some muscle already will probably find that they can perform more powerful muscle “explosions”, like when they lift particularly heavy weights.

This supplement is a good choice if you want to make the most out of every workout and see results fast. However, it does not offer any direct muscle gains or improvements; it’s just useful as a temporary performance enhancer.

Special Offers

CrazyBulk has a number of special offers going on at any one time. One of their more common discounts grants you the third item you choose free if you buy multiple supplements or accessories at the same time. You also get free worldwide shipping on every order you place regardless of how expensive or cheap it is.

Pricing and Dosages

The vast majority of CrazyBulk supplements can be purchased between $30 and $80 depending on what specials are running at the time and what savings you might get from bulk purchases. Most of the bottles also contain 90 capsules.

The exact dosage required for the best effects can vary from supplement to supplement, but most require you to take 2 to 3 capsules per day. As a result, each bottle is good enough for at least one month of use, provided that you take the supplements every day as intended.

This adds up to an average of $50 per month per supplement. This is about on par with the pricing and dosages of other muscle growth supplements on the market, so CrazyBulk is fine in this regard.


In addition to offering all of its products individually, CrazyBulk offers special “stacks” that are packages you can purchase in a group that combines several products together by either bulking or cutting themes.

The Bulking Stack

This stack comes with everything one could need in terms of muscle growth supplements. The stack comes with:

  • D-Bal to boost muscle growth
  • Trenorol to improve muscle growth and lower water retention for appearance
  • DecaDuro to increase strength gains with every workout
  • Testomax to improve your overall testosterone production and boost your energy level
  • A guide book to help you work out more effectively

The Cutting Stack

The Cutting Stack is designed specifically for gym goers that want to look their best and become lean and fit-looking as fast as possible. It includes:

  • Testomax to increase testosterone production for energy levels and fat burning
  • Clenbutrol to help you burn fat more effectively
  • Anvarol to protect your muscles from being consumed as you burn energy
  • Winsol to boost your stamina and endurance so you can have better cardio workouts

CrazyBulk for Women

CrazyBulk is certainly primarily marketed toward men. Both most of the pictures and its advertising language are decidedly masculine, and there’s even a supplement included specifically designed to increase testosterone production.

However, CrazyBulk can also be useful for women. In fact, many women looking to build muscle either in the competitive or aesthetic sense from using muscle growth supplements like those that CrazyBulk offers.

That’s because women naturally produce less testosterone than men and produced several other amino acids and hormones in lower amounts. They also produce a much higher amount of estrogen, which grants them their feminine qualities but also makes it a lot harder to build muscle. These factors combined mean that women have to work more than twice as hard as men to produce the same amount of muscle mass. Even in a perfect scenario, they can’t put on as much muscle overall.

At the same time, you don’t want to take steroids as a woman for the negative side effects we described earlier.

So healthy and natural supplements like CrazyBulk’s can be a huge advantage for women wanting to get fit and cut. Their supplements don’t have negative side effects that will make women appear or feel more masculine, but they provide many of the same protein-boosting and muscle preserving advantages that men can enjoy.

The only supplement that women will likely want to stay away from is Testomax, as this directly increases testosterone production. While a little extra testosterone won’t hurt anything, continued absorption of testosterone as a female will eventually lead to some mild side effects like the ones you experience upon taking regular anabolic steroids.

Possible Side Effects

So far we’ve gone over what CrazyBulk offers and talks a lot about their natural ingredients. But do these supplements come with any side effects?

On paper, there are no negative side effects you need to concern yourself with if you take CrazyBulk supplements correctly and in the right amounts. All of the CrazyBulk capsules are made with natural ingredients only instead of synthetic compounds or amino acids. As a result, all of the ingredients in every supplement can be processed easily by your body; they’re things you might normally get in much smaller doses from eating food.

That being said, side effects are possible if you take too many of the supplements in a short period of time. Saturating your body with too many of a particular compound is never a good thing, even for ostensibly healthy amino acids that increase protein synthesis. You may feel sick upon taking too many of the capsules or feel lethargic rather than energized.

In addition, not everyone reacts to the contained natural ingredients the same way. Just like people have normal allergic reactions or digestive disagreements with certain foods, some supplements just won’t be right for you. Certain mild side effects can include:

  • Heart palpitations or rapid beating
  • Increased sweating and overall body heat
  • Mood swings, particularly toward the aggressive side
  • Fatigue of the body, even before working out
  • Appetite changes, either growth or loss

If you experience any of the side effects, it’s recommended that you stop taking the CrazyBulk supplements until they subsist. This way, you can restore your body to its natural state and either try a different, lower dose of the same supplement or pick a different product.

You should also hesitate before using CrazyBulk supplements if you are on any kind of medication. It’s a good idea to double-check with your doctor and read the back of the bottle of the supplement you choose to see if the compounds within will interfere with your medication.

In general, though, CrazyBulk supplements don’t have any negative side effects to overly concern yourself about. They’re also a far cry safer than traditional steroids.

The Final Verdict

All in all, CrazyBulk supplements are an excellent choice for bodybuilders or men and women looking to generally increase their muscle gains and appearance. They offer supplements for muscle growth and for burning fat, making their catalog one of the most versatile on the market. They also offer most of their products for reasonable asking prices, and you can usually take advantage of a sale to get them for even cheaper than their regular costs.

We’d recommend CrazyBulk for any consistent gym-goer or folks dedicated to getting more muscular over several months.
