9 Trenbolone Side Effects - Are They Dangerous

Trenbolone has become a popular choice among athletes and bodybuilders because it helps them get the body they want while having few side effects.

The drug works by binding itself to the androgen receptors, which, in turn, leads to an increase in the levels of testosterone.

This increases protein synthesis, which lets the person build lean muscle mass while burning fat at the same time.

Furthermore, Trenbolone does not cause water retention, resulting in a cleaner appearance that is both aesthetically pleasing and in high demand.

Some people think that trenbolone is one of the most effective anabolic steroids for building muscle and losing fat. However, there is a big problem with using it.

Some of them are higher blood pressure, acne breakouts, hair loss, trouble sleeping, and maybe even anger.

Taking too much Trenbolone can also hurt your liver because it is hepatotoxic, and it can also stop your body from making its own testosterone.

Even worse, different esters of Trenbolone, such as acetate and enanthate, have similar side effects. However, the timing of these effects may be different for each ester type because serum testosterone levels peak at different times.

Trenbolone Side Effects

Blood Pressure and Cholesterol

Trenbolone is an anabolic steroid that has been used in bodybuilding and by athletes to increase muscle mass and strength.

However, it can have serious adverse effects on the body, including raising cholesterol levels, which can lead to cardiovascular strain and left ventricular hypertrophy, which are both risk factors for developing cardiomyopathy (heart disease).

To reduce the chances of atherosclerosis, it is recommended that users of Trenbolone engage in regular cardiovascular workouts and supplement with 4 g of fish oil per day to lower blood pressure. 

Stacking Trenbolone with other oral steroids should be avoided, as this has been shown to cause a dramatic increase in cholesterol levels due to their stimulating effect on hepatic lipase in the liver.

This combination could be devastating for those with heart conditions or diseases, as elevated levels of cholesterol can lead to plaque buildup inside the arteries, increasing your risk for heart attack and stroke.

Also, because Trenbolone is toxic, long-term use could cause high blood pressure and damage to the liver. 

Testosterone Suppression

Anabolic steroids are strong hormones that can have big effects on the body, like stopping the body from making its own testosterone.

As more athletes and bodybuilders use steroids to improve their performance and gain muscle mass, they need to be careful to protect their health and keep their T-levels at a healthy level.

When coming off steroids, there is often a “crash” period where natural active testosterone levels drop because the body is getting too many hormones from outside sources. This can cause symptoms like depression and trouble getting an erection.

To minimize this effect after cycles, individuals are advised to use caution with dosage, cycle length, and post-cycle therapy (PCT) protocols.

Gynecomastia (Gyno)

Trenbolone is very likely to raise progesterone levels, which can lead to gynecomastia in men who use it.

Progesterone is a female hormone responsible for regulating menstrual cycles in women, and the elevation of this hormone can cause gynecomastia, the development of excess breast tissue in men.

To help combat this, bodybuilders often opt for aromatase inhibitors (AI’s) or selective estrogen receptor modulators (SERMs).

AI’s blocks testosterone’s conversion into estrogen, thereby increasing testosterone levels and reducing estrogen levels.

SERMs, on the other hand, inhibit estrogen’s effects without affecting aromatization.

While both of these compounds are effective at reducing the risk of progesterone-induced gynecomastia, two popular SERMS Nolvadex and Clomid, should not be taken with Trenbolone as they increase progesterone levels and thus could potentially worsen the situation. 

Popular AI options include letrozole (Femara) and anastrozole (Arimidex). These compounds work by inhibiting aromatization, a process whereby testosterone is converted into estradiol.

By blocking this conversion, AI’s reduce estrogen levels in the body, which in turn helps reduce the risk of developing gynecomastia from elevated progesterone levels caused by Trenbolone use.

However, using an AI should not be done unnecessarily, as it can have significant cardiovascular effects if used too heavily or too frequently.

That being said, if one notices that nipples become puffy or swollen while taking Trenbolone then it would be wise to take an AI such as Letrozole or Anastrozole to help mitigate the risk of developing gynecomastia due to progesterone elevation caused by Trenbolone use.

Acne Breakouts

Trenbolone is a highly androgenic anabolic steroid, which can result in oily skin and acne vulgaris.

To combat this, many bodybuilders have seen positive results when taking Isotretinoin (commonly known as Accutane).

Research has demonstrated that 20mg per day of Isotretinoin is effective as a treatment for moderate to severe acne, as well as guarding against future breakouts.

Additionally, incorporating two popular aromatase inhibitors (AI’s) letrozole (Femara) and anastrozole (Arimidex) into trenbolone cycles helps reduce the chances of on-cycle acne.

With the right care, you can get the muscle-building benefits of trenbolone without breaking out in acne.

Hair Loss

Trenbolone is a powerful anabolic steroid that has a range of benefits for bodybuilders. It is often used during a cutting cycle to help increase muscle definition and strength, as well as decrease fat levels.

However, there are some potential side effects associated with its use. One of the risks of using trenbolone is hair loss due to its extremely high androgenic rating of 500.

This can cause elevated levels of dihydrotestosterone (DHT) which can lead to hair thinning or balding in individuals who are genetically predisposed to it.

While only short-term use may cause thinning or recession, it usually reverses post-cycle when DHT levels regulate back to normal.

To reduce the risk of hair loss from using trenbolone, some bodybuilders take medications such as Finasteride which block the conversion of testosterone into DHT, however, this may reduce muscle hypertrophy gains.

Additionally, certain supplements such as saw palmetto and biotin have been known to help reduce the amount of DHT produced by trenbolone and other steroids while also providing other health benefits such as improved brain function and stronger nails.

Furthermore, many bodybuilders opt for alternative treatments such as scalp massages with essential oils to stimulate circulation in the scalp and promote healthy hair growth during post-cycle recovery periods.

Visceral Fat

Anabolic steroids can have mixed effects on a person’s body composition. While they may be effective in burning subcutaneous fat, they can also increase visceral fat levels.

Unlike subcutaneous fat which is visible to the naked eye and is usually located underneath the layer of skin, visceral fat is found deep inside the abdomen, surrounding internal organs.

High levels of visceral fat can cause a bloated or protruding look in the midsection even after any subcutaneous body fat has been reduced.

Estrogen plays an important role in an increase of visceral mass, which explains why women typically store more body fat around their abdomens than men do.

Interestingly, trenbolone does not convert to estrogen; however, progesterone mimics certain effects of estrogen when it comes to body composition.

This means that even though abdominal muscles definition might be achieved with trenbolone use, users could end up having a bloated-looking stomach as well due to the increased level of visceral fat.

Anxiety and Depression

Aside from being an anabolic steroid, Trenbolone is known for its stimulating effect on the central nervous system.

This can have both physical and mental side effects, like making you irritable, anxious, paranoid, or depressed.

To counteract these consequences of using Trenbolone, users should consider consuming foods rich in l-tryptophan.

L-tryptophan is an essential amino acid that helps calm the nervous system by making you feel sleepy. Whole milk, turkey, chicken eggs, steak, and tuna, all of which are excellent sources of protein, contain significant amounts of l-tryptophan.

Eating carbohydrates along with l-tryptophan increases absorption rates considerably, making it more effective at reducing symptoms associated with Trenbolone use. 

Another thing to note is that l-tryptophan plays a key role in the synthesis of serotonin – a neurotransmitter responsible for regulating mood and sleep patterns.

It is especially beneficial for those suffering from anxiety or depression related to Trenbolone use. In addition to helping alleviate mental symptoms, l-tryptophan has also been shown to help reduce muscle fatigue and promote tissue repair after exercise. 

Therefore, users of Trenbolone need to make sure they are getting enough of this beneficial amino acid in their diet, as it can have a positive impact on both physical and psychological health.

Tren Cough

Trenbolone, a popular performance-enhancing drug among bodybuilders, can cause severe coughing fits that are commonly referred to as “Tren cough.”

This condition is estimated to affect 20% of those who inject the drug and can be accompanied by chest tightness and a metallic taste in the mouth.

It is believed that it is the potent androgenic properties of Trenbolone that cause vasoconstriction in the bronchus leading to coughing upon injection.

Moreover, similar symptoms may occur with Deca Durabolin or Testosterone injections but are far less frequent compared to Trenbolone.

Female Virilization

Trenbolone is an androgenic steroid that can cause unwanted changes in women’s bodies, such as clitoral enlargement, jaw hypertrophy, shrinking breasts, and a deeper voice.

While a professional female bodybuilder may accept these changes as a price to win competitions, there are other anabolic steroids better suited for women that do not cause femininity-compromising side effects.

Anavar, Primobolan, and Deca Durabolin have all been looked at for less severe side effects related to cholesterol and blood pressure.

If you are looking for more detailed information about suitable anabolic steroids for female athletes along with applicable dosing guidelines, it is recommended to read medical research articles that can provide up-to-date research on this topic.


Trenbolone is one of the most powerful anabolic steroids available and therefore should be used with extreme caution.

Due to its potency, side effects can range from mild to severe depending on dosage and cycle length.

Users should start with a small dose and slowly increase it as their bodies get used to the compound.

Additionally, users need to be aware that stacking Trenbolone with other anabolic steroids will amplify the potential side effects experienced.

Furthermore, those who are looking to stack Trenbolone should not do so alongside compounds known to have adverse effects on cholesterol levels or the heart, such as Anadrol, Dianabol, Superdrol, or Winstrol.

Advanced bodybuilders tend to be more suitable candidates for a cycle of Trenbolone due to their built-up tolerance for various anabolic steroids; however, even these users should proceed with caution given medical research showing Trenbolone’s not something that should be underestimated in terms of its potential risks.

If Trenbolone is used wrong, it can cause a number of physical and mental side effects, such as increased aggression, hair loss, acne, gynecomastia, or “man boobs,” and changes in sex drive.
