History and Overview

Initially released in the 80’s in the cattle industry under the name Finajet, Trenbolone enjoys a rather unusual history, marked by long periods of unavailability or excessive selling prices.

It was the French pharmaceutical brand Negma who developed the first Trenbolone compound for human use. However, the manufacturer stopped its production in 1997.

When Parabolan was discontinued, bodybuilders started to extract the Trenbolone acetate hormone from the Finaplix H cattle pellets. Since these pellets were by no means meant for human use, the obtained injectable compound often led to serious infections and abscesses.

Ever since all of the different esters available on the black market nowadays are either made in underground laboratories or they are veterinarian grade.

Since we are talking about one of the strongest anabolic steroids currently available on the market, Trenbolone should be avoided by those users who are just starting to use anabolic steroids. This compound should be used only by intermediate and advanced users who have already completed various testosterone (or other beginner anabolic steroids) cycles.

Is it legal to buy and use Trenbolone in the UK?

Trenbolone is currently available in the UK on the black market only as an underground compound and has no official pharmaceutical grade. Under the UK law, it is classified as a class C Drug. However, you are allowed to possess it for personal use.

There is a 100% legal equivalent of this steroid called Trenorol. More information on this supplement can be found below.

What about the USA and the rest of the world?

The USA has possibly the strictest laws in the world regarding steroids. It is not only illegal to sell and manufacturer steroids, but also, to own them for personal use.

Canada and Australia have laws which are more in line with the UK’s.

Best place to buy Trenorol?

The best place to buy this supplement is from the official manufacturer. By purchasing from there you will eliminate any chance of purchasing a substandard counterfeit.

Results Wise What Can I expect?

Available in three esterified variants – Trenbolone Cyclohexylmethylcarbonate (aka Parabolan), Acetate, and Enanthate.

This is an extremely potent anabolic steroid, delivering outstanding results. Some of the effects to expect are as follows:

• Outstanding muscle tissue growth, vascularity, density, and dryness

• Amazing strength and performance enhancement

• Boosts RBC count (i.e. increases the number of red blood cells)

• Enhances the direct fat burning process

• Increases mineral absorption, protein synthesis, and cellular repair

• Increases the nitrogen retention in muscle tissue

• Since it does not aromatize, there are almost no estrogenic side effects

• Almost no water retention

• Great results in a short period of time

As you can see, the benefits of this drug are definitely worth considering. However, such a potent anabolic steroid could not come without serious side effects (which we will discuss further on).


How does it work?

A derivative of Nandrolone, this steroid belongs to a category known as 19-nor compounds, a category that is defined by its resistance to any Estrogen conversion.

As a consequence, it is a very powerful androgen with a potent anabolic activity. This makes it ideal for rapid strength and muscle mass build-up. Usually, this compound provides users with outstanding results in a short period of time. The anabolic effects of Tren are often compared to those provided by famous bulking agents such as Dianabol.

However, there is one crucial difference: unlike other mass drugs, this drug cannot convert to estrogen. That means that users will not have to worry much about estrogenic side effects – such as gynecomastia, – and will still obtain, hard, very well defined muscle tissue, with almost no water retention.

This steroid’s high androgen level can accelerate the fat burning process as well, delivering a tighter physique (even in the absence of extreme dieting). This makes it a perfect contest preparation drug.

Since this steroid is five times more potent than testosterone, androgenic side effects are expected while using this compound. Aggression, oily skin, hair loss, and even acne are common side effects during cycles. Due to the androgenic nature of this steroid, those women who are considering its use should be extremely cautious, especially since certain virilisation side effects can be permanent.

As already mentioned, it is available in three esterified variants: Trenbolone Cyclohexylmethylcarbonate (aka Parabolan), Acetate and Enanthate. Their half-lives represent the major difference between these variants.

Trenbolone Acetate

The most popular of the three variants, Acetate is highly regarded for building muscle. However, due to its short half-life (i.e. around 1 day), it has to be administered every other day (and even daily). During cutting cycles, this compound is frequently stacked with testosterone propionate.

Trenbolone Enanthate

Another popular variant of Trenbolone, the percentage of active steroid of the Enanthate variant is almost 20% lower than that of Trenbolone Acetate. For this reason, the weekly dosage for Enanthate is higher than the one for acetate. With a 5 days half-life, this ester is usually injected 2-4 times a week.

Trenbolone Hexahydrobenzylcarbonate

This ester extends the compound’s activity for over two weeks, making it more comfortable to administer.

As we have already said, the differences between the three variants are negligible. It all comes down to the administration comfort.

Trenbolone dosage and use

Due to its non-aromatizing nature and potent androgenic activity, Trenbolone is an extremely efficient cutting and hardening agent.

Fat cells are known to contain androgen receptors. Since Trenbolone binds to the androgen receptors, the fat-burning process is accelerated. In addition, Trenbolone’s ability to bind to glucocorticoid receptors and reduce cortisol makes it an ideal compound for bodybuilders who are trying to reduce body fat.

The dosage depends on each user’s tolerance to the compound. The dosage varies between 35 mg and 150 mg per day. However, beginners should start with low doses and see how they react to the compound before increasing the dosage.

It is known that the results of Trenbolone cycles are enhanced when stacked with other anabolic steroids (e.g. Testosterone or Dianabol). Nonetheless, Trenbolone only cycles also give good results, but are not advised due to extreme natural testosterone shut down.

Acetate dosage

The usual dosage of Trenbolone Acetate is of 35-150 mg/day. Dosages higher than 150 mg are generally used to increase the nervous system stimulation. 100 mg/day dosages are used for mass or strength improvements. However, most users find themselves comfortable with 50-75 mg/day dosages.

Enanthate dosage

In the case of Enanthate, the weekly dosage ranges between 300-800 mg. Due to its effective half-life, the dosage can be split into 1-2 injections per week.

Hexahydrobenzylcarbonate dosage

Since it is a slow-acting ester, Trenbolone Hexahydrobenzylcarbonate is often administered at a dosage of 152-220 mg per week.

It is a known fact that the extended use of anabolic steroids might cause kidney damage and liver toxicity. Trenbolone makes no exception. Therefore, inexperienced users are advised to limit the use of Trenbolone to ten weeks. Experienced users might stretch this limit.

Side Effects

The side effects of this steroid are directly proportional to the extended list of benefits it provides.

Out of all the anabolic steroids out there, this is the one whose use requires the most caution. The side effects of Trenbolone can be very harsh, especially if you are sensitive to this compound or suffer from specific medical conditions.

Since Trenbolone has such a powerful androgenic activity, all those side effects that usually occur with strong androgens should be expected: male pattern baldness (if you are genetically prone to it), acne, oily skin, facial and body hair growth, aggression. Due to its powerful androgenic activity, females should avoid using totally. If they decide to use it, they can expect to experience virilisation (i.e. clitoral enlargement, deepening of the voice, acne, frontal hair thinning, and menstrual disruptions).

It is true that it cannot aromatise. However, since it is a progestin, it can cause gynecomastia if the user is highly sensitive to the compound.

Other common side effects worth mentioning are increased blood pressure, poor sleep patterns, insomnia, severe sweating at night or when performing routine physical activities (e.g. climbing stairs). Since it affects the cardiovascular functions. This steroid is not recommended to those athletes whose routine involves a moderate level of cardiovascular fitness.

Many users have reported negative effects on the kidneys. However, there is no accurate evidence of this. Perhaps this theory appeared due to the fact that, while using this drug, urine becomes much darker. But there is an explanation for this: since Trenbolone suffers little to no breakdown, the compound is excreted in the urine in a rusty, oxidised form.

Researchers tend to demonstrate that kidney damages are actually due to the increased water loss and sweating while using this steroid. This is why users are advised to up water intake greatly.

Since this steroid shuts down the natural testosterone production of the body, users can experience loss of libido, fertility issues, and, sometimes, even impotence.

Another famous side effect is the so-called ‘tren cough’, which tends to manifest itself after each shot. The common symptoms are tightness in the chest, a metallic taste in the mouth, and a violent cough which is difficult to control.

Can it Damage The Liver?

Trenbolone presents the same amount of stress on the liver as any other anabolic steroid. Since it is not C17-alpha alkylated, it exhibits a higher resistance to hepatic breakdown and metabolism. Its small amount of hepatotoxicity is far from the liver toxicity exhibited by C17-alpha-alkylated steroids. However, individuals with pre-existing liver issues should take special care.

Can it Cause Hair Loss?

This drugs strong androgenic activity can definitely cause hair loss, especially to those users who are genetically predisposed to MBP. Unfortunately, there is not much you can do to prevent this side effect.

Will it Make Me Aggressive?

This steroids powerful androgenic and anabolic activity can – and in many cases DOES – cause increased feelings of aggression and irritability in most users. However, these side effects are highly dependent on the used dosage (aggression and irritability are more frequent when users opt for high dosages). Those users who generally manifest anger-control problems should be extremely careful with using Trenbolone, as the compound might amplify those pre-existing problems.
