Intro

No matter how many times people want to argue about:

What is the most powerful anabolic steroid?

They can never bring forth their opinion unless they have actually tried Trenbolone (Parabolan).  It is truly the ‘Nectar of the Gods‘. Mainly because of the rapid physical and mental changes, not all necessarily good, that you can make using it.

Some of the brand names you may have heard being used are Finaplix, Finajet, and Hexabolan.  It is also sometimes called Trenabol by underground labs.  It has an anabolic to androgenic ratio of 500:500. Meaningon paper it is 5X more anabolic and androgenic than straight Testosterone. 

Discovery and history

Trenbolone (Parabolan) was developed in the 1960’s, under the Parabolan brand name by Negma Pharmaceuticals.

The purpose was to treat muscle wasting and bone problems in humans.  This flies in the face of conventional bro science where people will call it a ‘veterinary drug.’

Although today it is used to improve mineral absorption in cattle and boost mass of the cows, it was originally human grade!

Today it is obviously banned for human use but still used in some countries for veterinary purposes.  That hasn’t kept those in fitness from getting their hands on this amazing anabolic steroid. In fact, it is one of the most popular and inexpensive ones sold by underground labs.

Tren Esters

There has been an evolution for sure when it comes to Trenbolone (Parabolan) and what esters have been popular.

Hex

Today, very few people actually use the pricier hexahydrobenzylcarbonate (Hex) ester. Thus, most underground labs don’t even bother producing it.

Tren E & Tren Ace

The acetate (ace) and enanthate (E) esters are the two that are sold.  The difference between the two is the half-life which is 2 days vs. 10-11 days respectively.  You can read more about steroid esters here.

No-Ester

The detection times are up to 5 months, so it isn’t a wise choice to use any of the esters mentioned to dope.  However, the good news is you can use something called Trenbolone no-ester, which is in and out of the body on the same day and undetectable, since it has no ester attached.

The science behind how trenbolone works

Although all anabolic steroids pretty much do the same things like increase protein synthesis, increase nitrogen retention, prevent muscle wasting, and boost hormones in the body,  it is important to understand what separates them from each other from a science perspective.

In this case, Trenbolone (Parabolan) lacks a carbon atom at the 19th position which classifies it as a 19-nor (nortestosterone).  However, the difference with this and what you know as Deca Durabolin (also a 19-nor) is that Trenbolone (Parabolan) carries a double bond at the 11 and 9 carbons allowing it to easily bind to the androgen receptors.  This makes it super androgenic compared to any of the main anabolic steroids.

What it does better than any other steroid is literally force your muscles to absorb nutrients at a huge clip due to its strong anabolic nature.  It is similar to using insulin in that the more you eat the more it will cause you to get stronger and bigger.  Now you see why it is given to cattle.

Trenbolone (Parabolan) is truly the steroid that will take you to the next level in terms of size and breaking strength personal records.

Dosages and stacking

Trenbolone (Parabolan) can most certainly be used by itself at dosages ranging from 150mg to 500mg per week.  Any higher dosage will result in severe side effects.

If using in a steroid stack a lot of guys like to run some Testosterone with it, but I would not recommend using a lot as both compounds are androgenic.   Rather, a good option to stack with Trenbolone (Parabolan) is something like Anavar, Turinabol, Primobolan, or Equipoise due to their mild nature.

In addition, a popular strategy is to use Cardarine (GW501516) with it to offset negative side effects, especially with endurance.

Side effects

Inflammation

Trenbolone (Parabolan) increases the prostaglandin called PGF2A in the body.  This causes severe inflammation which will make it more difficult for a person to breathe on the compound, meaning you will have a tough time doing cardio or physical activities like hiking or climbing.

Aggression

It is also extremely androgenic, so expect major heart strain (high blood pressure, cholesterol problems), aggressiveness, mood changes, and insomnia.

Suppression

Like all anabolic steroids, it also will shut down your pituitary glands while on it, making it important to run a full post cycle therapy.

If you use it with a head hair killing steroid like Winstrol you will notice quite a lot of shedding, and if you use it with another harsh compound like Anadrol or superdrol you may feel lethargic.

The best way to combat side effects is never overdosing on this compound and stack it wisely.

Relationship killer?

Trenbolone (Parabolan) is known as a relationship killer due to the effects it can have on our midbrain and dopamine levels.  You may notice that you feel much more aggressive sexually while on, and feel tempted to cheat on your spouse or try new fetishes.  Many people will revert to old addictions when using it, so be careful!

Estrogen and prolactin

Trenbolone (Parabolan) will not affect estrogen levels. However it can skew blood work due to some labs picking up the metabolites as estradiol.

As far as prolactin I have found that this issue is rare unless you abuse the steroid. However, you can always use cabergoline (Dostinex) if you feel it is necessary.

Female use

Females should not use Trenbolone (Parabolan) due to its severe virilization side effects which may not be reversible.

User results and recommendations

Trenbolone (Parabolan) is a very powerful anabolic steroid. Those who have any sort of mental issues, addictions, relationship drama, poor heart health, or insomnia should not use Tren.

I also do not recommend those under 25 years old use tren and you should save it for when you have more experiences with steroid use.  You should not use tren as a first cycle because it is simply too powerful and strong.

Those that respect it, and use it wisely, will experience tremendous results in the gym.
