Trenbolone Review – The Holy Grail Of Muscle Building?

Trenbolone, a Nandrolone derivative, is an androgen and anabolic steroid (AAS) that, along with its Trenbolone ester cousins (including Trenbolone hexahydrobenzylcarbonate, known as Parabolan or Hexabolan, and Trenbolone acetate, known as Finajet or Finaplix), have been marketed in the past for clinical and veterinary use. These compounds were originally mainly marketed toward veterinary professionals aiming to quickly increase muscle growth in cattle and other livestock. Once injected into the muscle of the cattle, rapid muscle development would occur. Trenbolone and its esters are also taken illicitly by professional athletes and bodybuilders due to their muscle-growth-enhancing properties. Trenbolone is up to five times as potent as testosterone alone. As an added bonus, it does not aromatize into estrogen unlike some other anabolic steroids. This makes it especially attractive to bodybuilders who take the drug and want to avoid any unwanted excess estrogen in their systems. Due to its strength, it is not recommended for beginners. A weaker AAS compound such as testosterone should be used in its place. Due to its androgenic effects, it is commonly not recommended for use in women. Trenbolone is not legal and can only be obtained via illegal manufacturers.

How Does Trenbolone Work?

Trenbolone works best in conjunction with a Trenbolone ester. The most popular and widely available of these is Trenbolone acetate. Administration of these two drugs together helps increase the otherwise short half-life of Trenbolone to up to 3 days. Other esters are available, such as Trenbolone enanthate, which has a longer half-life of up to seven days. Some athletes prefer the enanthate ester because a longer half-life means less frequent injections and, ideally, fewer immediate post-injection side effects. Also, the enanthate ester provides a slower, longer lasting peak.

Once Trenbolone and its accompanying ester are injected and metabolized, they begin to increase the ammonium ion uptake in the muscles. This results in a much faster rate of protein synthesis, which in turn leads to rapid muscle development. Like other anabolic steroids, Trenbolone also increases appetite and decreases catabolism. It also binds with very high affinity to the progesterone receptor. Because of this, although the compound itself is not estrogenic, it does exhibit some progestogenic effects such as male breast tissue growth and shrinking of the testicles.

Benefits Of Trenbolone:

Bodybuilders and athletes prefer Trenbolone to the variety of other AAS options available for several great reasons. As previously mentioned, Trenbolone can be up to five times as potent as testosterone, another popular performance enhancer. Additionally, Trenbolone does not have some of the unpleasant side effects of other anabolic steroids. For example, unlike testosterone, Trenbolone does not cause fluid retention. This can lead to a more muscular and lean appearance more quickly.

Another positive aspect of Trenbolone is that it does not aromatize to estrogen once in the body. This is a tremendous downside to several other anabolic steroids and hormone injections. The benefits of this are two-fold. First, the Trenbolone stays in the body as Trenbolone much longer than other drugs stay in their pure form. Second, the testosterone-to-estrogen balance is not disturbed. The unpredictability of other drugs’ half-lives and their metabolic products make Trenbolone an attractive choice to those looking to have greater control over their blood chemistry.

Trenbolone is a very strong anti-glucocorticoid. This means that it binds with high affinity to the glucocorticoid receptor, which controls cortisol levels in the body. As cortisol decreases, the body’s consumption of fat as an energy source increases. This makes Trenbolone an incredibly effective fat burning tool. This, combined with its anti-fluid-retention properties, allows Trenbolone to give users a uniquely sculpted appearance in a much shorter amount of time than similar compounds.

Side Effects

It is very important that consumers be educated on the pros and cons of a drug before incorporating it into their lives, even if for just for a short period of time. Unfortunately, every drug has side effects and Trenbolone is certainly not without its fair share. Like other anabolic steroids and androgens, it can cause an increase in several undesirable qualities. Users report feeling extreme aggression, and the characteristic “roid rage”. Many consumers also have experienced feeling excessively hot, particularly at night. This is due to the fact that Trenbolone is a stimulant and increases blood pressure and heart rate.

A healthy heart is no doubt the cornerstone of every athlete’s overall fitness. Trenbolone, like most anabolic steroids and androgens, has negative effects on heart health in the long term. Because of this, is it not advised to use for long periods of time. Aside from raising blood pressure and heart rate in the short term, Trenbolone has farther-reaching cardiovascular side effects. In one case study, a young man who had used Trenbolone for bodybuilding purposes over the course of a year presented twice to the emergency room with arm pain and nausea. Since he was young and in otherwise good physical health, the doctors did not suspect heart issues and sent him home. Only after multiple visits and an eventual referral to a cardiologist did they discover that he had used Trenbolone so extensively and that it had caused permanent damage to his cardiovascular system.

Many factors of long-term steroid use contribute to a decline in cardiovascular health, but a major one is their effects on cholesterol levels. Steroids increase the levels of high-density lipoprotein (HDL, or “bad” cholesterol) and decrease the levels of low-density lipoprotein (LDL, or “good” cholesterol). Athletes already spend valuable time and money managing their diet and exercise habits to ensure peak physical condition, so it is important to account for unwanted side effects of any drugs included in your regimen. This is another reason why cycling drugs is so important, because effects in the long term are compounding.

Another reason to not use Trenbolone in the long term is that over time it can cause irreversible liver damage. This is a common side effect to the long-term abuse of many drugs and is not to be taken lightly. Also, some users report experiencing impotence long after discontinuing Trenbolone. Erectile dysfunction is most likely due to the cardiovascular effects of anabolic steroids on the body, however with proper cycling and very short-term use they can be minimized.

There are also a few less serious side effects to consider. As previously mentioned, although Trenbolone is not estrogenic, it does have prostaglandin effects. These can cause swelling in the male breast tissue over time. Another well-known side effect is “tren cough”. The mechanism behind it is not well understood, but it is suspected that the anti-inflammatory effects of the prostaglandins cause constriction of the blood vessels, specifically in the bronchus. The body’s natural reaction to this is to cough. Fortunately, most users find it does not last long after injection, although some find it so severe and debilitating that it causes them to rethink their decision to use the drug altogether.

As with other anabolic steroids, Trenbolone use will often cause acne and hair loss. This is particularly a risk for people who are already genetically predisposed to hair loss. The acne may subside after stopping the drug, but unfortunately hair loss is permanent and is definitely something to be considered.


Trenbolone is so popular and widely known for a reason: its results are undeniable. With the use of Trenbolone and a Trenbolone ester such as acetate or enanthate, athletes are able to build muscle insanely fast. Additionally, since it will not cause fluid retention the way that comparable anabolic steroids and androgens do, muscle gains look more pronounced, clean, and lean like the below picture.

after results

Results from Trenbolone acetate will begin to show within a week. Trenbolone enanthate results will take a bit longer, usually from two to three weeks. The “peak” times of each drug vary due to their differing half-lives. Trenbolone acetate, with its 3-day half-life, will give a quicker peak. Trenbolone enanthate, whose half-life tends to be around 7 days, will take longer to peak (but its results obviously last longer!).

Post-cycle therapy (PCT) is recommended after using Trenbolone or nearly any anabolic steroid. The standard dosage of Nolvadex or Clomid should suffice. Failure to properly do a PCT cycle will result in drastic loss of gains and tremendous hormone imbalances that can take weeks or months to recover from.

Recommended Dosage


The recommended dosage for a first-time user is 175mg-350mg per week. Trenbolone is only available in an injectable oil form, and the injection goes in the muscle. Again, Trenbolone is not for beginner steroid users or women. As with all new drugs, trying a small amount and seeing what works for you is always the best plan. Additionally, since Trenbolone is only available through underground manufacturers and labs, it is much safer to use a smaller amount than necessary since buyers can never be 100% sure of the concentration, potency, or composition of what they are purchasing through these channels. This helps to minimize potential side effects and dangers while getting a feel for how your body reacts to a new substance.

By all accounts I have come across, even a small amount of Trenbolone for a short amount of time should produce visible results. It is widely referred to as the strongest anabolic steroid available for bodybuilding purposes.

Final Thoughts

Trenbolone is an extremely powerful anabolic steroid and androgen that will give tangible, dramatic results quickly. That said, it is not without its faults. As previously mentioned, Trenbolone is absolutely not for beginners or women. This obviously excludes a large part of the bodybuilding population. However, beginners may be drawn to taking Trenbolone against this advice due to the indisputably fantastic results it can provide. I would strongly advise against beginners taking Trenbolone. Until you have gone through several cycles, at least some of which including other anabolic steroids and androgens, you will be unprepared for how your body handles such a strong drug with such serious potential side effects.

On the subject of side effects, Trenbolone probably has the most severe and greatest number of side effects of any drug in its category. The side effects most easily noticed by users will be on the milder side. These include acne, “tren cough”, aggression, excessive sweating, and a higher heart rate. These do not usually deter users as many of them are similar to the side effects of nearly any AAS drug. Unfortunately, the more serious side effects, particularly those found after long-term use, will not be noticeable until it is too late to do anything about them. Severe effects such as cardiovascular disease, heart attack, stroke, liver damage, and even erectile dysfunction can persist years after stopping Trenbolone. Some will be lifelong and can even result in death. For this reason, nobody recommends taking Trenbolone in the long term. It is simply not worth it. For people who choose to incorporate it into their cycling routines, keeping it minimal is key. In fact, some users do not recommend cycling with Trenbolone at all and use it strictly in pre-competition times to increase muscle appearance temporarily. Regimens such as this will help keep side effects to a minimum.

A popular alternative to Trenbolone is Trenerol. Manufactured by the company Crazybulk, Trenerol is a steroid-free natural supplement that allegedly rivals the efficacy of Trenbolone without the side effects. It is legal and readily available online without a prescription. For those hesitant to take on the baggage of a strong anabolic steroid like Trenbolone, Trenerol is definitely a viable alternative.

As always, never begin a new drug regimen unless you are healthy and educated enough to do so. Starting small will help minimize potential risks and give you a better idea of how your body responds to Trenbolone. In the short term, controlled use of Trenbolone can help you attain impressive gains in an insanely short amount of time. For experienced bodybuilders, a Trenbolone cycle is certainly something to consider trying. As any number of before-and-after pictures will show you, the results speak for themselves.
