Trenbolone AcetateTrenbolone Acetate is considered by many professional bodybuilders to be the best anabolic steroid every synthesized. Talk to different users at different gyms and you will get varying stories about Trenbolone and what it can and can’t do.

It’s gained a lot of attention in the past – as most steroids have – but it’s also retained a kind of mystique as the steroid that seems to be able to do everything.

If you want to know the hard facts about Trenbolone, and not the broscience and nonsense being spouted at you by some acne-ridden dude by the benchpress, continue reading…

Trenbolone is also known as its shortened form, Tren, but it’s more widely recognized as “Fina” after the first brand names it traded under; Finajet and Finaject. These were veterinarian grade steroids first synthesized in the 1960s. A pharmaceutical version called Parabolan was manufactured with an ester attachment, which was the only chemical alteration to the animal grade Fina.

Crazybulk TrenorolParabolan would be the only human grade cut of Trenbolone but it didn’t make it, ultimately succumbing to the same fate as most anabolic steroids, and was discontinued in the late ‘90s. The vet-grade Trenbolone Acetate that had come out of the ‘60s had been stopped in the ‘80s, even before the human grade stuff, but it made a reappearance as Finaplex.

Finaplex came in the form of pellets which were placed in the ears of cattle to dissolve and improve the lean tissue before slaughter day.

Bodybuilders and athletes have used this pelleted form of Trenbolone by making an injectable Trenbolone Acetate. This is still practiced by some people but the black market has also advanced in more recent years and there are pre-prepared injectable forms of Trenbolone Acetate.

Trenbolone Acetate is a favourite because it outstrips other steroids at bulking, cutting and strength cycles. We’ll look into that more in the next section.

Trenbolone – Benefits to the Bodybuilder / Athlete

Trenbolone is five times the anabolic and androgenic ratings of testosterone due to a simple alteration to its structure.

It also binds very tightly to the androgen receptor while having low aromatization activity. It is also a fairly fast acting steroid.

It’s a lot like other steroid from an anabolic standpoint, it promotes:

  • Nitrogen Retention
  • Protein Synthesis
  • IGF-1 Production
  • Red Blood Cell production
  • Muscle Hardness, Strength, Vascularity

Crazybulk User CustomerAll of the above create an anabolic environment in muscle tissue, and Trenbolone appears to accomplish this more potently compared to most if not all other anabolic steroids.

In terms of cutting fat, Trenbolone binds tightly to the Androgen Receptor (AR) and by doing so can trigger direct fat burning and inhibit cortisol based hormones.

Cortisol is known as the stress hormone, and it can create a catabolic environment (muscle breakdown) especially during dieting phases and cutting cycles.

Trenbolone can be used during a bulking cycle, as is evidential from its anabolic traits, however it is also used during a cutting cycle due to its:

  • Cortisol Inhibition
  • Direct Fat Burning

What makes it particularly useful is the combination of its anabolic and fat burning traits. People tend to lose some muscle during a cutting cycle no matter what but Tren can reduce the catabolic state.

So for the person bulking, it will prevent them from adding on body fat mass, and for the person in a cutting cycle it will improve muscle retention.

Finally, Trenbolone increases the uptake of nutrients from food. This is due to the demands it puts on the body by increasing all the other aspects of anabolism and androgenicity. Diet therefore becomes an extremely important part of any cycle that includes Trenbolone Acetate.

Trenbolone Side Effects

DoctorLike any anabolic androgenic steroid, Trenbolone users should be prepared for the possibility of side effects. Although it is a lot more potent than most steroids with respect to its anabolic and cutting benefits, it is not necessarily true of its side effects.

The negative side effects of Trenbolone don’t include estrogenic effects such as excess water retention but it can cause:

  • Gynecomastia (man boobs)

The gynecomastia is not a result of aromatization of the Tren but the progesterone promotion of it which can trigger breast tissue to grow.

When used in combination with other aromatizing steroids this side effects can become worse. Users tend to need estrogen blockers as part of their on-cycle therapy.

Androgenic side effects are possible given Trenbolone’s affinity to the androgen receptor. These include:

  • Acne
  • Male Pattern Baldness, i.e. an accelerated rate if predisposed

Some people who use Tren need not worry about the baldness if they are not predisposed to it.

Cardio Vascular problems can arise in the form of:

  • Increased LDL (aka, bad cholesterol)
  • Increased Blood Pressure

Other side effects include:

  • Testosterone Suppression – Trenbolone’s suppression of natural testosterone production is strong compared to most steroids, perhaps with the exception of Deca Durabolin (Nandrolone). Deca can shut down natural testosterone production in one shot. Steroid users usually take exogenous (synthetic) testosterone in some form in order to supply the body with some testosterone and prevent themselves from entering a low testosterone state, a condition which can be extremely bad for health.
  • Anxiety
  • Insomnia
  • Night Sweats
  • Heart Palpitations

The last four side effects there are known as “response effects” which are the effects particular to a steroid, in this case Trenbolone Acetate. There is nothing life threatening there but they can be severe and can sometimes be the reason a person stops using Trenbolone even if they experience no other negative effects.

Trenbolone Usage

Trenbolone Acetate BottleIt’s important to remember that Trenbolone has not been approved for human use and so there can’t really be said to be an optimal usage guideline.

Most people find an underground lab that makes liquid injectable Trenbolone but it is against the law to do so.

Also against the law is to purchase the Finaplex pellets which are intended for livestock. Even buying the paraphernalia required to convert the pellets into an injectable liquid is technically illegal.

Hopefully you will also forgive us if we do not give explicit dosage information for using Trenbolone Acetate. The steroid – any steroid – can have different effects on different people and where some men can tolerate 100mg every other day, others would find 50mg every other day more than enough. Trenbolone acetate’s concentration is 75mg/ml of liquid.

Judge Steroid LawTrenbolone is a very powerful steroid, and it can have potent side effects if the user does not tolerate it well. It goes without saying that caution must be assumed every step of the way with anabolic steroids, not to mention the peripheral issues of needle use and hygiene.

With the exception of testosterone, trenbolone is probably the most popular anabolic steroid on the black market. While it sounds like an easy thing to purchase some, the more popular a steroid is the more chance there is of coming across counterfeit gear that is either garbage or dangerous. Neither option is good nor worth risking your neck over.

Trenbolone Conclusion and Recommendations

Steroid SyringeTrenbolone Acetate is one of the most popular and potent anabolic steroids available to black market buyers because it is so versatile, slotting into cutting cycles and bulking cycles and easily being the most potent steroid in the stack. During both phases it can increase strength incredibly.

However, it is also illegal and can have severe side effects depending on the tolerance level of the individual using it.

The steroid comes in two forms: a liquid which must be injected intramuscularly, most likely every other day for the cycle duration, and solid cattle ear plugs under the name Finaplex. An injectable acetate form can be made from the ear plugs, but this can often cause confusion for the person doing it.

Underground labs tend to make a prepared liquid form, however underground labs are also unscrupulous more often than not.

An important consideration is that someone using Tren must Crazybulk Legal Trenalso inject Testosterone due to the potency of Tren’s testosterone suppression. They are also likely to need estrogen blockers and possibly even Finasteride, or another 5-AR blocker to prevent too much conversion to DHT (to prevent premature balding) however this has not been shown to be overly effective.

Together with on cycle medication to mitigate the potential side effects there is a course of Post Cycle Therapy that will be required. And on top of all this is the risk of cardio vascular side effects.
