Many people want to know: Does Crazy Bulk work? We asked Ernst Peibst to answer this question, an English natural bodybuilder, who’s impressively transformed his physique several times (and has used almost every supplement known to man).

Steroid alternatives are certainly a hot topic in bodybuilding right now. Steroid alternatives are supplements which are formulated to replicate the effects of anabolic steroids (but without the dangerous side effects).

They claim to get users jacked, without risking their health.

This is a huge statement, causing some people in the fitness industry to be wary of companies making such claims. This can result in bodybuilders calling products ‘scams’ before even trying their products, or doing much research.

Firstly, I have personally tried some of the ingredients included in Crazy Bulk’s products, so I can give genuine feedback as to whether they really work or not.

Before I share my experience, readers should know that Crazy Bulk’s steroid alternatives are the following:

  • 100% legal
  • Do not require a prescription
  • Are approved by the FDA
  • Are not dangerous (unlike anabolic steroids)

My Experience With Tribulus (Crazy Bulk Ingredient)


I would like to share my experience with a natural herb I took roughly 8 years ago called tribulus terrestris. I took this in my early weight lifting years, where I would buy every supplement under the sun to test it out.

Tribulus terrestris is one of several ingredients in Crazy Bulk’s best-selling supplement – D-Bal.

Some readers may already know about tribulus, which is used in bodybuilding as a natural testosterone booster and a post cycle therapy to enhance endogenous testosterone levels after a steroid cycle.

Tribulus is a herb from the Zygophyllaceae family, touted to enhance libido, sexual performance; whilst increasing muscle mass and strength.

Steroid-Like Gains

If I could use two words to describe my experience on tribulus terrestris, they’d be: steroid-like. 

My strength went through the roof in the first week, adding roughly 10kg to big compound lifts like it was nothing. Such strength gains were a common occurrence, that carried on increasing until the end of the month.

My muscles blew up dramatically, looking bigger and more defined each morning when I looked in the mirror. In fact, before I even made it to the bathroom I could instantly feel that my muscles were bigger upon waking up.

T-shirt sleeves became tighter and everyone started commenting on how much bigger I looked. This was the first time in my weight lifting journey, where I was making rapid muscle gains. I must’ve gained at least 12-15lbs of lean muscle tissue in the first month of taking tribulus.

I would bump into people on the street who I hadn’t seen in a while, and they’d stop and tell me how jacked I was now (which was an epic feeling).

There was a personal trainer down my gym who’d noticed my muscles ballooning up in size and asked what I was doing. I told him I was taking tribulus, and he mentioned that he also had very good gains on it (ruling out the possibility of me potentially taking a tainted batch!).

I Turned Into the King of Alpha Males

At the time I was at college, and it wasn’t just my body that was changing dramatically. I had suddenly become super alpha. I was already a pretty confident guy, being popular in school, but tribulus took my confidence to a whole new level.

It was obvious that this new-found confidence was due to the huge surge in testosterone I was experiencing. I oozed confidence to the point where men were jealous of me and women were drooling over me. I would act and say things in a way, where I even surprised myself.

To make a movie comparison, I had turned into the guy off Limitless (Bradley Cooper), or Peter Parker, when the venom symbiote takes over his body and his persona starts to change.

This scene was literally me…and my pill was tribulus.

Note: I didn’t take tribulus to feel more confident at all, however this was a surprising bonus, in addition to all the muscle I gained. 

I literally felt like a superhero, and nothing felt impossible for me to achieve (no matter what it was). Some might call this delusional, but it was my reality. I wasn’t into the whole sleeping around thing, as I was seeing a girl at the time, but if I wanted to – I could have had my pick out of all the girls in college (easily). Some of them even knew I had a girlfriend, yet were still disappointed when I turned them down.

I don’t want this to sound like an egotistical post, but this was just what was happening.

My libido also went through the roof, where I’d be horny all the time, with endless random erections.

The Side Effects

What goes up, must come down.

Did I experience any side effects? Yes I did.

A general rule with steroids is: the more gains you experience, the worse your side effects will be.

This was certainly applicable to me, despite taking a natural testosterone booster.

Towards the end of my cycle I felt like my blood pressure was increasing and I would guess that it was high. I also experienced a higher body temperature, plus some anxiety and depression.

This was the comedown from the insane euphoria I was experiencing in the early and mid stages of my supplementation.

After doing some research, I discovered that tribulus had stimulative effects. Thus, it was revving up my central nervous system, causing my body to produce more adrenaline (hence the increase in body temperature). When the body increases adrenaline production, it can shift into fight or flight mode. Consequently, the body can start to perceive harmless situations as threats; resulting in anxiety. Stay in this mode for too long and serotonin can decrease, hence the low mood and depression.

I guess it felt a little like I would if I had taken steroids (but less extreme). This is the post cycle period where the world seems darker and gloomy, and you become a mere mortal (compared to your former extra alpha self).

I asked questions to people who had tried tribulus to see if they experienced the same side effects I did. And based on what they said I came to the following conclusion:

If you experience incredible gains with steroid alternatives, you will experience side effects. But if you don’t notice much in the way of gains, you won’t experience any crash or adverse effects.

I believed I experienced the effects I did because I’m sensitive to stimulants, thus it had a big impact on my nervous system during and after supplementation.

I also noticed that my hair got a little thinner from taking tribulus, however this wasn’t an issue as I naturally have very thick hair. Also I’m sure this thickened out again after I stopped taking it.

Why Did Tribulus Give Me Such Good Gains?

There is mixed research regarding tribulus. Some studies suggest tribulus is very powerful for increasing free testosterone levels, the unbound form of testosterone, that is a powerful muscle-builder. Whilst others deem it to be a placebo. My experience certainly wasn’t a placebo as I experienced steroid-like gains (that I wasn’t expecting).

Tribulus studies:

  • DHT levels increase by 25% (1)
  • Test levels spike significantly in just 10 days (2)

Bulgarian athletes who dominated weightlifting in the 1970’s also reported enhanced strength and muscle gains from using a Bulgarian tribulus terrestris extract. This was what initially peaked the interest of bodybuilders, looking to get jacked from this herb.

The increase in DHT in the first study makes sense to me, as high DHT levels can increase damage to the follicles on the scalp. This was why I experienced some thinning of my hair and soreness on my scalp. However, I would guess my DHT levels rose a lot more than 25%.

Other studies on tribulus concluded that participants did not experience any elevations in testosterone when taking the herb.

Such conflicting results, correlates with real-life user experiences on tribulus, where people can notice steroid-like gains, or minimal gains. Supplements generally are very much like this, where one product can work wonders for one person, but do nothing for the next person.

However, based on my gains, I recommend trying Crazy Bulk’s D-Bal supplement (containing tribulus). If you experience the gains I did, whilst having some short term side effects; overall you will be delighted with the results.

Note: Tribulus terrestris is just one of the testosterone-boosting ingredients in Crazy Bulk’s D-Bal formula. It also contains ashwaganda, Suma Root Concentrated Extract and vitamin D3.

Crazy Bulk Before and After Pictures

The following transformations have been posted on the official Crazy Bulk website from their customers.

Balwinder took clenbutrol for 5 weeks helping him transform from skinny/fat to ripped.

Cole took trenorol and winsol helping him to build significant amounts of muscle, whilst burning fat at the same time.


Which Crazy Bulk Products Will Work Best For Me?

This depends on your goals and budget. For example, if you want to build muscle and you have plenty of spare cash, Crazy Bulk’s bulking stack will produce the best results. This is a stack of: D-Bal, Trenorol, Testo-Max and Decaduro. However, if someone is on a limited budget, D-Bal is the best of these supplements.

If someone wants to lose fat, then the cutting stack will accelerate fat burning, whilst helping to keep the body anabolic (preventing muscle loss). The cutting stack consists of: Clenbutrol, Anvarol, Winsol and Testo-Max. If someone can only afford one of these supplements, clenbutrol will boost a person’s metabolism the most, producing the most weight loss.

If someone wants to build muscle and burn fat at the same time: D-Bal, stacked with Clenbutrol would be a shrewd choice. This way you have the best bulking supplement, combined with the most powerful fat burner. Also when you buy 2 of Crazy Bulk’s products, you get a third free.

Do I Need to Take a PCT After Using Crazy Bulk?

Steroid-users incorporate post cycle therapies, taking anti-estrogen medications to increase their testosterone levels. This is because anabolic steroids shut down your natural test production.

A PCT is not needed after taking Crazy Bulk’s products, because they will raise your natural testosterone production, instead of shutting it down. Thus, serum testosterone levels will not decline in the blood stream.

Are the Results From Crazy Bulk Permanent?


Muscle size can be lost after taking anabolic steroids because users can lose a lot of intracellular water which collects inside the muscle cells during a cycle. Thus, when they cycle off, they can experience a noticeable decrease in muscle thickness, in conjunction with a loss of strength. Also testosterone levels plummet after using steroids, creating a muscle-wasting state in the body.

However, Crazy Bulk’s supplements will not cause any of the above. The muscle gains you experience from their products will be permanent, as their products won’t cause significant water retention or shut down your testosterone production. Thus, your body will remain in an anabolic (muscle-building) state, even after you stop using their supplements.

However, to maintain the results experienced from Crazy Bulk, be sure to continue training hard in the gym. If someone’s diet or training begins to worsen, results can naturally become less (indirect of the supplements).

So, Does Crazy Bulk Work?

Based on the above reviews and transformations on the official website, there is evidence Crazy Bulk does work.

I can also vouch for their ingredients working, based on my experience when taking tribulus, a key ingredient in D-Bal. This genuinely gave me steroid-like gains, gaining roughly 15lbs of lean muscle in 30 days. For someone who isn’t a beginner, you can only dream of gains like this. To this day, out of all the supplements I’ve tried, this remains easily at #1.

My only criticism would be that some of Crazy Bulk’s customers may experience side effects. They say that their supplements don’t produce any adverse effects, however in my case I did from tribulus (one of their ingredients). However, I can agree that the side effects will certainly be mild compared to real steroids. Although for the gains I experienced it was certainly worth the temporary adverse effects.

An authoritive third party review website named Feefo has collected thousands of reviews from verified Crazy Bulk customers. Over 2,300 Crazy Bulk customers have left feedback, accumulating a very positive rating of 4.4/5.
