Guide to Trenbolone Acetate and FAQs

Trenbolone Acetate Frequently Asked Questions

trenbolone acetate

At some point in our lives, we’ve all wanted to run faster, jump higher, launch our best friend like a shot put ball – all while having to beat women off of us like an Axe commercial. For those of you that have really tried to get into the best shape possible, you probably know that it’s easier said than done if you’re not using something like trenbolone acetate. Even when constantly changing up workout routines to be as challenging as possible, our bodies experience plateaus or genetic limitations that prevent us from continuing to build muscle and lose body fat. These limitations have increased the popularity of the anabolic steroid Trenbolone Acetate.

You might ask why we have decided to do an article about Trenbolone Acetate on our health website… The first reason would have to be education. Regardless of potential side effects or the dangers of hormone supplementation, people are going to use steroids. It is our intention to educate these individuals so that they may avoid any negative effects that could occur if used incorrectly. There is currently a huge epidemic in the United States, and throughout other countries, referred to as Body Dysmorphic Disorder, where individuals become extremely unhappy with their physical looks. This disorder is responsible for thousands of suicides each year and proven to kill more people than steroids ever have. Steroids are sometimes prescribed to individuals with Body Dysmorphic Disorder in order to boost their self esteem. In recent years, there has been talk that trenbolone may be submitted for FDA approval for human use for its ability to help those with anemia and other hormone-related disorders.

What is Trenbolone Acetate?

Trenbolone Acetate (also known as “Tren” or “Trenabol”) is an anabolic steroid and a derivative of Nandrolone. The chemical was formulated in the 60s and was produced in the 70s by a company in England called Hoesct, and in France by Roussel . Trenbolone acetate was sold under the brand names Finajet and Finaject and was sold in the prescription drug market under those brand names for human use. However, due to a declared anabolic steroid “epidemic” declared by governments in the 1980s and early 1990s, production for human use was discontinued. It was around this time that bodybuilders began to experiment with Trenbolone acetate and began to see the amazing effects that the steroid could produce.

What differentiates Trenbolone Acetate from Other Anabolic Steroids?

Trenbolone Acetate has three very unique characteristics that set it apart from your average anabolic steroid. The first characteristic being that Trenbolone acetate has a very strong affinity for the androgen receptors which makes it an extremely potent steroid. Several sources say that the strong affinity that trenbolone acetate has for androgen receptors make it five times more potent that testosterone compounds. The second unique characteristic of Trenabol is the drugs amazing resistance to aromatization into estrogen. We’ll get into the benefits of this characteristic in a later question, but this makes it very preferential to some users due to the fact post-cycle therapy is not 100% necessary. Some anti-estrogen drugs can actually be more difficult to obtain than anabolic steroids. The last important characteristic that makes Trenbolone acetate a great anabolic steroid is the steroid’s resistance to metabolism by the body, making it a long-lasting steroid with a long half life.

What is Trenbolone Acetate Used for?

The primary use for trenbolone acetate today is for veterinary purposes. The drug is typically given to cattle to increase mineral absorption, to increase appetite in cows that aren’t eating as much as average livestock, and to improve muscle mass in cows that are experiencing atrophy or eating disorders.

Am I old enough to Take Trenbolone Acetate?

While we (nor the FDA) do not encourage the use of trenbolone acetate in any human individuals, it is strongly advised that nobody under the age of 25 take trenbolone, or any other anabolic steroid for that matter. Those under the age of 25 years old still have bodies and organs that are not finished developing. Messing with the body’s Endocrine system (hormones) is never a good idea unless it is malfunctioning. This is especially true in individuals that are still developing because hormonal changes will have impact on these developments.

How is Trenbolone Acetate taken?

Trenbolone acetate, like most steroids, is almost always injected into the body. Most steroids are also available in oral form, but generally aren’t very bioavailable when taken orally. Trenbolone is somewhat more bioavailable than most steroids, due to its resistance to metabolism by the body, but still requires a much higher dose when taken orally. Many report more side effects and more pronounced side effects when taking tablets vs. injecting the steroid. Due to additional passes through the liver, steroids can also be more toxic and may cause additional damage to the body when taking oral form rather than injecting. I know this is horrible news for those that are afraid of needles, but your options are to avoid steroids all together, get over your fears, or take on additional risks of damage to your internal organs. In the future, it is likely that steroids will be discovered or created in oral form and be safer/more bioavailable, but so far, there aren’t many of these drugs available. If injecting trenbolone acetate, ensure that shots are given away from any major veins or arteries. Sterilize the injection site thoroughly, and dispose of needles immediately after use. Never share needles with anybody!

Is Trenbolone Acetate Legal?

In most countries, trenbolone acetate is only legal for veterinary uses. The FDA currently does not have trenbolone acetate approved for human ingestion or treatment of any diseases or disorders. However, this does not stop bodybuilders and other from using it. In the United States, trenbolone acetate is currently a Schedule III Controlled Substance, meaning that harsh penalties may come with getting caught with the substance.

Is Trenbolone Acetate Safe?

This is a difficult question to answer. If steroids are used within certain doses, and if frequent blood tests are done to ensure hormone levels aren’t highly out of whack, it can be safe. But similar to the use of any type of drug, there will always be risk of side effects. However, trenbolone acetate may be safer than most steroids due to its resistance to typical metabolism by the body.  Whereas most steroids elevate liver enzymes, trenbolone seems to be expelled from the body in a different manner which means less stress on the liver and kidneys than most steroids.  We strongly recommend weighing the benefits vs. the risks before even considering using trenbolone acetate.

Does Trenbolone Acetate have Side Effects?

All drugs have potential side effects, so to no surprise, trenbolone acetate use may come with some unwanted side effects being that it is a very potent anabolic steroid. Some trenbolone acetate side effects include:

Increased perspiration – It’s important to drink extra fluids with trenbolone acetate. Trenbolone users have been known to sweat much more during workouts and some even perspire at random times of the day, regardless of surrounding temperatures.
Insomnia –While some steroid users encounter sleeping disturbances, those that have used trenbolone acetate say that it’s not only common, but can be very difficult to counter – even by taking sleeping medication with the steroid. Some studies suggest that trenbolone acetate may have a direct stimulating effect on the central nervous system. This profound side effect has lead to the term “trensomnia” by many in the anabolic steroid community.

Gynecomastia Problems – Gynecomastia is the term used to describe men who develop large breasts, similar to that of a woman’s breasts. This is one of the most feared side effects of steroid users, and rightfully so, because the changes can sometimes be permanent. However, they’re usually able to be reversed to a large degree, if not fully. Unfortunately, even though trenbolone acetate has resistance to aromatizing into estrogen, it seems to increase the body’s sensitivity to estrogen (which is always present to some degree), and increases the release of prolactins from the Pituitary Gland. This increase in prolactin levels is thought to be responsible for the highly unwanted side effect of gynecomastia. Those that experience issues with gynecomastia during trenbolone cycles may want to use a dopamine agonist alongside trenbolone acetate. Dopamine/Prolactin-agonists have been known to decrease prolactin levels to a degree. A few examples of prolactin agonists are Bromocriptine, Pramipexole, or Cabergoline. Vitamin B6 has also shown to reduce prolactin in some studies as well.

Decreased Libido & Erectile Dysfunction – Many users of trenbolone acetate experience difficulty getting or maintaining erections. This unwanted side effect is commonly referred to as ‘Tren-dick’ by bodybuilders and other in the steroid community. This side effect is thought to also be caused by increases in prolactin levels by the Pituitary Gland.

Many users also experience a significant decline in libido or sexual desire. Some users will only experience these side effects to a degree. Many users may easily obtain erections and actually experience increases in sexual desire, but may not be able to achieve orgasms during sexual activity. Sexual changes are quite common, and to be experienced with trenbolone acetate. These effects usually subside after trenbolone use is discontinued. It is highly recommended that you keep some form of prolactin-agonist on-hand during trenbolone use in case you experience these issues.

Increases in Aggressive Behavior – Like with any androgen, trenbolone may increase aggression and irritability in individuals. These side effects are almost entirely dose-dependent. Not everybody reacts to drugs in the same manner. This is especially true for those altering hormones. However, those prone to aggression or those that have experienced anger issues in the past may want to start off with a low dose of trenbolone acetate until they are aware of how it may affect them, or trenbolone acetate.

Will Trenbolone Acetate Interact with Any of My Current Medications?

Because trenbolone acetate has not had many human studies conducted, there is not much information available for drug interactions. It is highly recommended that you speak with your primary care physician to discuss potential adverse effects or interactions with other drugs that you may be taking. There are some obvious drugs that you should avoid with any steroid use including testosterone (and other steroid) containing drugs such as Androgel, Testim, etc. Trenbolone acetate may also interact negatively with medications used to treat hypertension or hypotension such as Clonidine, Toprol, Diovan, etc. Medications used to treat heart conditions are also likely to interact with trenbolone acetate. Some of these medications include Warfarin and Heparin.

Does Trenbolone Acetate Aromatize?

Trenbolone acetate does not aromatize into estrogen. This is good news for some, but this can also cause other issues since the body relies on balance of hormones to operate at normal function. Estrogen levels may actually fall to low levels with the high amount of androgenic activity and lack of aromatization. Low levels of estrogen may cause joint inflammation/problems, mood changes, and loss of libido.

How long is Trenbolone Acetate Usually Taken?

The most common cycle for trenbolone acetate is 12 weeks. However, many users of trenbolone acetate cycles of 8 weeks have also shown to be effective for gaining muscle and reducing body fat. It is strongly recommended to use trenbolone acetate for a maximum of 12 weeks.

Do I need to Cycle Trenbolone Acetate?

Yes. All steroids should be cycled in order to prevent the body from completely shutting down production of certain hormones such as testosterone. Cycles also prevent the body from building up too many hormones that can cause massive damage to the body. A trenbolone acetate cycle of 8-12 weeks is long enough to achieve desirable effects without experiencing bothersome side effects.

What is a Typical Dose of Trenbolone Acetate?

Trenbolone is typically taken every other day in dose ranges of 35mg – 150mg and commonly taken with testosterone or Dianabol since Tren suppresses testosterone production. The most common dose of trenbolone acetate is 75mg every other day. Those that have never taken steroids should start with a lower trenbolone acetate dosage of 35mg – 50mg every 48 hours. More experienced users may want to use higher doses of 75mg – 100mg. While some of the more experienced users of steroids may take doses of up to 150mg every other day, this high of a dose is not recommended because of excessive central nervous system stimulation and the high risk of side effects that users may encounter.

What Results Should I Expect with Trenbolone Acetate Use?

Trenbolone acetate is well known for its ability to quickly build muscle and increase strength ability. These effects are caused by the drug’s ability to increase nitrogen retention, synthesize proteins, and rapidly repair cells. Many users also experience great cutting abilities (or the ability to rapidly reduce body fat without losing muscle fiber). It is important to increase the amount of food that you typically eat during steroid use to achieve desired results.



While we do not recommend using trenbolone acetate due to its limited research in humans, we hope that this information will help educate you should you decide to use it anyways. Trenbolone can produce extremely impressive muscle building and fat shedding results if used properly. While your doctor will strongly advise against the use of trenbolone acetate, it is wise to discuss your use with him before using the drug. Doctors have a duty to discourage steroid use, but most will monitor your hormone levels through blood tests to help ensure safety if you ask them to.
