Trenbolone is a steroid substance used in bodybuilding and other sports to enhance performance. This substance is a derivative of nortestosterone. It has some similarities with other substances also created for fattening cattle. Its use in both humans and livestock is currently completely prohibited.

Trenbolone was distributed in the 1980's by the pharmaceutical companies Hoescht and Roussel (USA and France respectively). Interestingly, both companies gave very similar names to this steroid - Finajet for the American version, and Finaject for the European version. Finajet was mainly used on cattle to improve appetite and increase muscle mass. Although the FDA (American Food and Drug Administration) never approved trenbolone for human consumption, it quickly gained popularity among bodybuilders. This was due to its terrific androgenic activity and lack of estrogenic manifestations.
However, in 1988, Hoescht stopped sales of Finajet on the American market, and a little later the French company Roussel did the same with Finaject. As a consequence, the widespread use of trenbolone by bodybuilders quickly ceased. Because trenbolone had not been available for some time, it developed a certain mythical aura among bodybuilders. However, in 1986, Roussel received approval from the FDA to release trenbolone in granular form under the trade name Finaplix. Therefore, the break in the availability of trenbolone was quite short. Moreover, shortly after all these developments, imported Mexican Trenbol 75 also became available. Injectable Trenbol 75 was usually preferred, as it required special ingenuity to extract trenbolone from Finaplix granules.
Produced by the French pharmaceutical company Negma, Parabolan was the only version of Trenbolone created specifically for humans. That being said, the production of this steroid was discontinued in 1997, and since then, you can only get your hands on veterinary trenbolone or clandestine versions of this drug. Be that as it may, due to its incredible reputation, trenbolone has always been highly sought after and it is likely to hold its position in the market for a long time to come.

Due to the fact that trenbolone is a derivative of the hormone nandrolone (Deca Durabolin), it can be said that it belongs to the family of 19 nortestosterone (19-nor). At the same time, two fundamental modifications have been made to trenbolone, thanks to which this steroid has properties that nandrolone does not have. The double ligaments in positions c9 and c11 occupy the ligaments necessary for aromatization, which completely deprives trenbolone of the opportunity to aromatize. Unlike trenbolone, nandrolone does not actively aromatize, but it is still converted to estradiol.

Another significant difference between trenbolone and its parent nandrolone is its androgenic activity. Trenbolone is so extremely androgenic that according to the androgenic-anabolic rating, it is 5 times more powerful in this respect than testosterone. This is possible due to the fact that trenbolone does not interact with 5-alpha reductase enzymes, and therefore, it does not convert to dehydrotestosterone (DHT). In addition, the previously mentioned double ligaments c9 and c11 increase the binding force of androgen receptors, thereby giving more power to trenbolone.

Injectable trenbolone is available with three different esters: acetate, enanthate, and hexahydrobenzyl carbonate. It is very important to remember that esters do not affect the work of the steroid in any way, and the only thing they change is the rate of release of the active substance into the blood.

Trenbolone acetate can easily be called the most popular version of this steroid. There are three reasons for this. First of all, compared to other esters, acetate is the most affordable. Secondly, due to the short half-life of this ester, trenbolone is a relatively easily controlled steroid. It is washed out of the body very quickly, which allows you to stop taking it very quickly in case of severe side effects. Thirdly, since parabolan stopped being produced in 1997, and until the advent of trenbolone enanthate, bodybuilders had no real alternatives to trenbolone acetate. On the other hand, due to the short half-life of acetate, more frequent injections are required. Bodybuilders usually inject themselves with trenbolone acetate every other day, and some every day. Of course, this is a significant drawback of this ether, since there is little pleasure in such a number of injections.

Introduced in 2004, Trenbolone Enanthate is the most recent version of trenbolone. However, trenbolone enanthate is not as modern a steroid as it may seem, because in fact, it is just a scion of Parabolan with another ester.

Due to the fact that enanthate has a longer half-life, trenbolone enanthate can be injected once a week. Some bodybuilders inject themselves twice a week, but those additional benefits are not enough to justify taking trenbolone enanthate so often.

Trenbolone hexahydrobenzyl carbonate is better known by another name — parabolan. Compared to enanthate, parabolan has two huge advantages. First, he starts acting faster, dismissing the need for another steroid to give a "boost" to the course. While trenbolone enanthate is better known as a slow starter. Secondly, it has an even longer half-life, which makes it possible to give injections even less often.

Interestingly, bodybuilders agree that parabolan is more powerful than the other two versions of trenbolone. Despite the fact that esters only affect the release rate of the active substance of steroids, trenbolone hexahydrobenzyl carbonate has something that gives it extra power. Unfortunately, after the production of parabolan stopped in 1997, it became almost impossible to find its originals on the black market. So the last source of parabolan was clandestine producers.

Although not as popular as injectable options, there are two versions of trenbolone for oral administration. The first of them is oral trenbolone acetate. In fact, it is a standard trenbolone acetate that is taken orally. At the same time, he has no structural changes that could protect him from splitting in the liver. Therefore, bodybuilders reasonably doubt its effectiveness.

The second version is Metribolone (methyltrienolone), methylated, so that it can remain intact when passing through the liver. However, this structural change implies the presence of one big drawback — a high level of hepatotoxicity. This is what pushes many bodybuilders towards less toxic injectable versions of trenbolone. Moreover, it is not just hepatotoxic — it is extremely hepatotoxic. Therefore, if you dare to test this particular version of trenbolone, be sure to take regular blood tests and take dietary supplements to maintain the liver.

Due to the fact that trenbolone does not aromatize at all, there will be no estrogenic side effects when taking it. Therefore, even those who have a predisposition to estrogenic manifestations will not have to worry about water retention, accumulation of subcutaneous fat and gynecomastia. However, there are a number of side effects with trenbolone that you should always keep in mind.

Due to the highly androgenic nature of trenbolone, side effects such as acne, pronounced hair growth on the body/face, and baldness are highly likely to occur. Due to the fact that trenbolone is so much more androgenic than nandrolone, the probability of these side effects is also higher. Unfortunately, since trenbolone cannot be converted to DHT, auxiliary drugs like Proscar will not help in the fight against baldness while taking this steroid.

In addition, the above-described androgenic activity can significantly affect the mood of a bodybuilder. According to some stories, intense aggressiveness and irritability may occur while taking trenbolone, especially if there is a predisposition to such behavior. Therefore, we must be prepared for a possible deterioration in mood and take measures to prevent any aggressive actions.

Trenbolone suppresses the natural production of testosterone very strongly and quickly. Therefore, a very strong PCT is required, for which drugs such as Clomid or HCGenerate ES are suitable. It is still not known why trenbolone has such a strong suppressive effect despite the fact that it is not converted to estrogen. According to one common theory, the blame lies on the activity of progesterone, since usually any sex hormone can suppress the production of testosterone in the body. Anyway, the strong suppressive effect of trenbolone obliges to PCT.

This is another common problem among bodybuilders who take trenbolone. Unfortunately, the origins of this problem are unknown, and there is no scientific justification to explain insomnia in trenbolone users. Dietary supplements based on theanine (L-theanine) can alleviate this condition. N 2 Sleep has performed well in eliminating sleep problems.

There is one side effect that occurs with all steroids, but is more intense in the case of trenbolone — cough. It is so strong with trenbolone that English-speaking bodybuilders have even dubbed it as "Tren-caught", which can be loosely translated as "Trending Cough". A steroid-related cough occurs when a small portion of the oil enters the bloodstream through small capillaries that can be punctured during injections. As a result, the body tries to get rid of the foreign substance through the lungs, which provokes a cough. Unfortunately, with trenbolone, this cough can be very severe, and if a bodybuilder has no experience with this steroid, you can get scared.

Despite the fact that injectable trenbolone does not contain a 17-alpha-alkylated (17aa) group, it may be somewhat hepatotoxic due to the resistance of its chemical structure to cleavage in the liver. Although the level of its toxicity was not close to the toxicity observed in steroids with group 17aa, it is recommended to take such liver protection supplements as N2Guard. If the course of trenbolone is administered with an oral version, especially a methylated one, taking N2Guard is simply necessary.

Excessive sweating characteristic of trenbolone is not dangerous to health, but this side effect should be mentioned in the context of dehydration. Since this steroid wildly accelerates metabolism, you will experience more intense sweating than usual, particularly at night. This can lead to significant water loss followed by dehydration. Therefore, it is recommended to drink more water during the tren course.

Trenbolone has one side effect, which certainly affects asthmatics. When taking large doses, trenbolone can increase the level of prostaglandin F2 alpha, which can lead to bronchial constriction. Moreover, the higher the dose, the more the production of prostaglandin F2ALFA increases, which exacerbates the problem. Consequently, the user will experience problems with heavy breathing, especially during physical exertion. As a rule, this side effect does not pose any danger to ordinary athletes, and disappears shortly after completing the course of trenbolone. However, if trenbolone is taken by an asthmatic, many precautions should be taken, and if possible, another steroid should be chosen altogether.

There are many rumors in the bodybuilding community regarding the toxicity of trenbolone to the kidneys. The main argument for such statements refers to the dark rust color that urine takes when taking trenbolone. Many people confuse this color of urine with blood. However, everything is much simpler. Trenbolone oxidizes to a dark color like rust, and when its metabolites are excreted in the urine, it turns the same color. Moreover, many studies conducted on humans and animals have proven that even after a long course of taking trenbolone, the kidneys were not damaged.

Although trenbolone does not convert to estrogen, according to some scientific studies it has a certain progestogenic activity. Very often, progesterone can provoke side effects that are very similar to estrogenic side effects. Fortunately, due to the fact that there have been no known cases with such side effects, it can be assumed that trenbolone's progestogenic activity is not strong enough to give estrogen-like side effects. At the same time, with a certain level of estrogen in the blood, elevated progesterone levels can enhance estrogenic manifestations. This should be remembered when trenbolone is combined with other steroids that are aromatized, as it can exacerbate their estrogenic side effects.

Trenbolone also stimulates the production of prolactin in the pituitary gland, which can lead to a whole series of side effects associated with prolactin. First of all, elevated prolactin levels can lead to sexual problems such as decreased libido and even impotence. Moreover, prolactin can cause lactation from the nipples, and together with progesterone, they can lead to gynecomastia. This point confuses many, because in theory, progesterone should suppress the production of prolactin. However, trenbolone, as well as nandrolone, are not progestins per se — they can simply activate progestin receptors without being one. There are two main solutions to this problem. The first is the use of anti-prolactin drugs like Cabergoline. The second solution may be to combine trenbolone with testosterone, which can solve the problem with prolactin.

The specific dosages of trenbolone will depend on the goals pursued by the user and the combined steroids. Usually, the acetate version is injected every other day, with a dosage of 50 to 200 milligrams (mg). The average duration of a course of trenbolone acetate is 10 weeks.

The longer-acting esters enanthate and hexahydrobenzyl carbonate allow for less frequent injections of trenbolone. They are injected once a week, with a dosage of 400 to 600 mg. The recommended duration of the course is between 10 and 12 weeks.

Oral versions of trenbolone are very powerful and toxic to the liver. For this reason, a very precise and balanced dosage is required. Usually take 0.5-2 mg per day. Significant hepatotoxicity also limits the duration of the course of administration, making the maximum allowable duration 4 weeks.

Despite the fact that trenbolone is usually associated with drying, many tend to forget that it is noticeably more anabolic than testosterone. The reason for this misconception is very simple and straightforward — due to the estrogenic activity, it seems that testosterone gives more mass. However, most of this increase is just water, which leaves the body shortly after completing the course. On the other hand, better muscle mass is built up with trenbolone. Although it seems that the gain is weaker with trenbolone, at the end of the course, much more mass is retained with it. So in the long run, trenbolone gives more mass, and it can be used with tremendous success for drying and for weight gain.

It is not surprising that trenbolone is so popular as a drying steroid, because it is perfect for any combination. Bodybuilders claim that trenbolone combines especially well with steroids such as Winstrol and Primobolan. As a result, it turns out to develop a relief figure with good drawing, which makes trenbolone an excellent pre-competitive steroid.

However, if the use of trenbolone were limited only to drying, it would not be such a universal steroid. Trenbolone can be used in weight gain courses, and its advantages will be difficult to overestimate. In such courses, it should always be combined with testosterone to alleviate the overwhelming side effects. In combination with Deca Durabolin or Equipoise, it can give a very balanced physical shape — very massive, but at the same time quite sinewy. Trenbolone will add relief to the mass that will come from the Soundboard or EQ.

Serious bodybuilders who want as much mass as possible, regardless of water retention, can combine trenbolone with such weight gain monsters as Anadrol or Dianabol. Without any doubt, the weight gain will be huge, and a little hardness will be added to it with the help of trenbolone.

Trenbolone is truly a legendary steroid with a very rich history. However, the title of the most powerful steroid ever created has its price - a noticeable number of side effects. Many of these side effects are very pronounced, and require an experienced approach to the issue. Therefore, this AAC is not recommended for beginners who want to explore the world of professional bodybuilding. On the other hand, when used correctly, trenbolone is one of the best steroids in the world — it has amazing anabolic/androgenic activity, and there are no estrogenic side effects.

Trenbolone helps to achieve a noticeable increase in high-quality musculature without the need to retain fluid due to an increase in carbohydrates in the diet. When a person wants to naturally increase their muscle mass, they should consume more carbohydrates in order to always have maximum glycogen reserves in their muscles. This way, the best results are achieved in training. However, it is not taken into account that in order for the body to absorb 1 gram of carbohydrates, it needs to include 4-5 grams of water in the body. This is the reason that fluids are trapped in the body. With trenbolone, you can build high-quality muscles without subsequent fluid retention. It is used both at the volume stage and at the definition stage. Many people use it at the fat burning stage, whose diet is hypocaloric and high in protein, to optimize the preservation of muscle mass.
