Trenbolone (Enanthate) Cycles, Fat Loss, and Results

Class of Compound


Mechanism of Action

Trenbolone (Enanthate) is an anabolic steroid that binds to the Androgen Receptors (ARs) in muscle and stimulates the muscle to synthesize more protein leading to muscle mass gain. It is known to be 5 times more anabolic than Testosterone.

Street Names

Chemical Structure

The following is my trenbolone review, based on what I’ve experienced talking to tren-users and consulting some of the best doctors in the world regarding this powerful steroid.. I’ll list all the pros and cons I’ve noticed (as well as other possible interactions) from taking this steroid.

Trenbolone in the bodybuilding world is regarded as one of (if not the most) powerful steroid on the market today.

Trenbolone can be used when bulking to build huge amounts of muscle and strength. And it can be used on a cut, to increase fat burning and help keep you looking BIG.

Trenbolone is known to be 5x more anabolic than testosterone.

Trenbolone is a controversial, with some people complaining that it’s a harsh steroid, whereas others say this is just a myth…and it actually isn’t any worse than other compounds.

After doing much research reading about people’s experiences/reviews on trenbolone, I’m going to list the common effects a user will face when taking tren…both the good and the bad!

Different Types of Trenbolonetrenbolone acetate

There are three different types of trenbolone:

  • Trenbolone acetate
  • Trenbolone enanthate
  • Trenbolone hexahydrobenzylcarbonate

All three versions of trenbolone are different because they have separate half lifes. This means that each of these compounds will take a different amount of time to clear out of the body.

It also means they have different length esters, thus gains will come by faster/slower depending on which one you take.

For example, trenbolone acetate has a short-ester and thus will be fast-acting. It will also clear out of your system quicker after you stop taking it. On the other end of the spectrum, trenbolone enanthate has a much longer ester, meaning you’ll have to be more patient when it comes to making gains as it won’t enter the body as fast and will take longer to exit your body.

Cyclohexylmethylcarbonate has an ester more like enanthate and is thus slow-acting.

By learning more about each form of trenbolone, it’s easy to understand why acetate is the more popular version of trenbolone.

Trenbolone 5x More Powerful Than Testosterone?

trenbolone transformation

Those who have tried trenbolone will be able to testify how powerful this anabolic steroid is. Those who haven’t tried tren might not fully understand it’s force.

To give us a bit of insight, lets compare it to testosterone.

Testosterone is a similar type of compound that can be used to build huge amounts of muscle in the off-season, but also can be used when cutting to speed up the fat loss process.

Testosterone has an anadrogenic score of 100.

Trenbolone has an androgenic score of 500.

So trenbolone is 5x stronger than testosterone when it comes to boosting male hormones such as DHT.

Holy moly!

This also explains why trenbolone is famous for causing huge growth in muscles like your traps and shoulders. These are muscles which have higher androgen receptors and thus will become bigger on trenbolone, because of its extremely high androgenic nature.

Because of this effect on DHT levels, hair thinning and receding is more likely on tren compared to other steroids. However, some do report that this effect does reverse post-cycle and their hair begins to look thicker again.pgy300003h7rj32ln89a

Insane Strength

By this I don’t mean ‘Oh, your strength will go up a lot’.


I always become as strong as an ox when I’m on tren.

Another user said he added 90lbs to his bench press on tren, and fast! (1).

The reason why tren is one of the best steroids for rapid strength increases, is because it’s super anabolic (high test) and it’s super androgenic (high DHT). Both of these male hormones have a dramatic impact on how much metal you can lift.

Cycles with Trenbolone

Best Steroid Cycles for Cutting Using Trenbolone

The goal of a cutting cycle is to burn off the maximum amount of fat without sacrificing lean muscle tissue. The best steroids for cutting are Anavar, Winstrol, Proviron and Trenbolone.

Your cutting cycle for Anavar should be the same as the beginner cycle mentioned in the last section; Begin with 15 mg per day for 3 weeks and then step it up to 20 mg for three weeks. Your off cycle should be the same length as your on cycle.  The best legal alternative to Anavar cutting is also Anvarol.

Your Winstrol cutting cycle should follow a six week on cycle following by six weeks off. Begin with 20 mg per day for the first two weeks, stepping it up to 25 mg per day for the final month. The best legal alternative to Winstrol is Winsole.

When taking Proviron for cutting, follow an 8 week on cycle followed by 8 weeks off. Take 20 mg per day for the first four weeks, stepping it up to 25 mg per day for the last four weeks.

When taking Trenbolone for cutting, follow an 8 week cycle, followed by 8 weeks off. Take 150 mg per day for the first four weeks, stepping it up to 225 mg for the final four weeks. The best legal alternative to Trenbolone is Trenerol.

For the most amazing fat loss results, the best steroid cycle stack for cutting combines Winstrol, Proviron and Trenbolone using the dosages listed above.

Anadrol, Trenbolone and Test Cycle

best steroid cycle for mass

Anadrol, trenbolone and testosterone stacked together are arguably the best steroid cycle for bulking and simultaneously the most dangerous one. The mass gains from this trio of bulking steroids will be tremendous. However, the side effects are also going to be very harsh, even for veteran steroid-users with much experience.

High dosages are listed in this cycle, which is typical for users with more experience. This cycle should be considered highly dangerous. 

Winstrol and Trenbolone Cycle

winstrol tren cycle

Trenbolone will add to Winstrol’s fat burning and drying out effects; creating a more shredded appearance.

Muscle gains will also be enhanced, compared to taking Winstrol alone.

However, winstrol and trenbolone are two of the harshest steroids you can take. Thus, side effects are going to be severe; particularly testosterone suppression and blood pressure values. Estrogen can help to regulate blood pressure, but with Winstrol and trenbolone failing to aromatize, this will not occur.

Generally, there is no need to take these two steroids together when cutting, as fat loss can be achieved through diet alone; instead of taking toxic steroids which can negatively effect your health in the long term.

Thus, if trenbolone is going to be used, it may as well be incorporated in a bulking cycle; where its effects are maximized in regards to lean muscle gains. However, users who are the exception and tolerate trenbolone well or aren’t concerned with their health may use it during cutting cycles.

See all cycles here.

Huge Muscle Gains

This ones pretty straightforward. If you use trenbolone whilst bulking you’re going to have ridiculous gains.

One user said he was taking trenbolone and testosterone together and was wiping the floor with his buddy in the gains department who was taking testosterone and deca.

…and deca is a pretty nifty bulking steroid.

Rich Piana also described trenbolone as an “amazing steroid, that changed (his) body enormously. Harder, leaner, vascular and grainy”.

Full/Pumped Muscles

Trenbolone removes water retention located outside the muscle cell and draws it inside, making your muscles become fuller and look constantly pumped (in and out of the gym).

Ps. if you’re planning on doing supersets whilst on tren…

  1. You’re a brave man.
  2. Get ready for some crazy-ass pumps!

More Ripped

Because tren shifts water from outside the muscle and relocates it INSIDE the muscle cell, your muscle tone and definition will increase A LOT.

You’ll also become noticeably more vascular as there is less water inbetween your veins and skin.

This is pretty nifty if you want to look ridiculously aesthetic on a bulk…and you happen to hate water retention (the bad kind).

Also if you’re bulking and plan on overeating, but want to keep your six pack abs visible, tren could make this happen.

…Assuming you’re mildly overeating, instead of adopting a Super Size Me diet.

Trenbolone Results (Before and After)

“Eat clen and tren hard”

You’re probably thinking ‘What can’t tren do?!’

The answer is: not a lot.

Because it’s extremely anabolic and essentially a fat burner, trenbolone can be used during bulking and cutting phases. However it’s more popular in the offseason due to it’s ability to add huge amounts of lean mass (without water retention).

Despite it being a great bulking steroid, those who do use tren when cutting will experience it’s great muscle-sparing attributes; neutralizing any catabolic effects that sometimes come with eating in a calorie deficit.

Trenbolone is also a diuretic, meaning the amount of times you visit the bathroom will increase…

Your body flushing out extracellular water like this, will increase muscle hardness and definition, making you appear more ripped.

Once you finish a tren cycle, your muscle gains and fat loss will be largely permanent. The only change you might experience is gaining a small amount of water post-cycle. This is just the diuretic effect wearing off.

Typical Trenbolone Results

As you already know, bodybuilding is a game of genetics and everyone responds differently to steroids. Some love trenbolone and think it’s the greatest steroid ever, whilst others avoid it because it gives them bad side effects.

When using trenbolone during a bulk, you can expect to gain 15-20lbs of lean mass from a 4-week cycle.

From an 8 week cycle, you may gain 25-30lbs. However the longer you cycle trenbolone, the more likely it is you’ll experience side effects.

Trenorol (a legal alternative to trenbolone) is considered safe by the FDA and won’t cause such side effects.

Some visual things you might experienced on tren include:

  • Enhanced vascularity
  • Increased sweating
  • Thinner skin, due to a reduction in water (under the skin)
  • Flushed or red-looking skin
  • Bigger pumps

When using trenbolone during a cut, you can expect some noticeable fat loss.

You won’t melt as much fat compared to other cutting steroids, such as anavar or clenbuterol; but it will be noticeable. Trenbolone is so anabolic, that you’ll most likely build muscle whilst cutting…unless you’re super aggressive with your cut and only consume a very low number of calories.

Does Trenbolone Really Cause Fat Loss?

Most people will say that tren DOES increase fat-burning. However, others say tren does nothing to burn fat because that’s whats happened in their own personal experience.

The truth is, trenbolone WILL cause fat loss.

However, the bad news is, it might not burn fat to the extent of other powerful fat burners.

So if you’re bulking on tren and eating in a calorie surplus…don’t expect to get shredded by the end of your cycle; you’ll end up disappointed.

However, if you add trenbolone to a cutting stack and eat in a calorie deficit; the fat will practically melt away before your eyes.

These are 2 completely opposite scenarios.

If you did something in the middle of both of these; so lets say you ate at maintenance calories and took tren…you’re likely to build a good amount of muscle and burn a little fat.

So, does Tren burn fat? Yes.

Will it get you ripped to shreds in 4 weeks if you’re 15% body fat? No.

How Does it Burn Fat?

Trenbolone is a powerful antiglucocorticoid. 

In English, this means it blocks cortisol receptors, so this catabolic stress hormone is significantly reduced.

When cortisol levels spike – the body stores fat.

When cortisol levels drop – the body burns fat.

So, the less cortisol you have when cutting the better; thus making trenbolone a perfect fit.

Also trenbolone has thermogenic properties, due to it being a stimulant. Hence how many users experience “feeling hot” and “sweating more than usual”.

…The latter is also known as tren sweats.

Increasing the body’s temperature like this elevates your metabolism, helping you burn additional calories throughout the day (similar to how clenbuterol works).

So, trenbolone thermogenically stimulating your metabolism also encourages fat loss, but it doesn’t guarantee it. Especially if you’re eating more donuts than Homer Simpson.

Steroids to Stack With Tren for Enhanced Fat Loss?

Simply taking trenbolone alone won’t do much in the way of fat loss. But if you were to combine tren with other powerful fat burning compounds such as:

  • Winstrol
  • Anavar
  • Clenbuterol

…You’re going to be a lot leaner/ripped by the end of your cycle.

Cutting steroids can help you lose a lot of fat if you’re eating and training well. But they aren’t miracle drugs where you can just pop a few pills without going to the gym, then wake up next week looking like Zac Efron.

Bodybuilding is a sport where success is impossible unless you’re extremely dedicated. Yet some people think steroid-users bodies are easy to attain, if they only took the same cycle.

This is why many people take steroids, but only a few actually look great. This is because many steroids-users workouts are weak, their nutrition is off and their genetics are poor. But if you’ve got decent genetics and you work your butt off, steroids like trenbolone can get anyone VERY lean.

How does trenbolone compare to other cutting steroids when it comes to fat loss?

I would rank the following as the best 4 steroids for fat loss (in order):

  1. Clenbuterol
  2. Anavar
  3. Winstrol
  4. Trenbolone

Clenbuterol actually isn’t a steroid, however it has steroid-like properties and incredible fat-burning attributes so it gets the top spot.

Anavar is one of the most popular steroids on the planet, mainly because it’s a great fat burner and it’s fairly mild. Thus you’re not likely to experience harsh side effects on anavar because of its low toxicity. Anavar, like trenbolone will also flush excess water out of the body, making you look more toned.

Winstrol is a solid steroid to take if your goal is to get lean. It will flush out extracellular fluid, like var and tren, and will reduce your body fat percentage. Winstrol is better than clen and anavar in regards to building muscle tissue. You’ll build muscle on winny, but not as much as on trenbolone.

Testosterone would come in at number 5 on this list just after trenbolone. Test is often referred to as a bulking steroid due to its powerful anabolic effects. However, when combined with a calorie-controlled diet, testosterone enhances fat loss.

Want evidence that testosterone is a good fat burner? Think of a typical guy, who’s genetically blessed with high testosterone levels, not only is he JACKED – but 9 times out of 10 he’s also very lean.

Trenbolone Results (Before and After Pictures)

steroids before and after

Jaco De Bruyn’s transformation is similar to those who take trenbolone. You’ll gain a lot of muscle and get ripped to shreds…assuming you work hard in and out of the gym.

See how Jaco’s veins are popping left, right and centre in the after photo and how full his muscles look even when competing on stage (where many bodybuilders look depleted).

He’s also extremely dry, which is the result of trenbolone’s diuretic effects. The way his body looks, in terms of looking like a 3D animation, is typical of a trenbolone user.

Guys who use trenbolone are usually very easy to identify, because their body stands out A LOT. They have a ‘photoshopped’ look to their bodies, due to certain muscle groups popping out; such as traps and deltoids. These muscles are more prone to muscle growth because these muscle groups have a high number of androgen receptors.

And as trenbolone is an extremely androgenic steroid, it causes these two muscles in particular to blow up!

Striations are also a lot easier to achieve on trenbolone, due to low levels of water collecting outside of the muscle cell. You can expect striations to appear once you’re under 6% body fat.

How to Maximize Gains on Tren

If you’re cutting and would like to get insanely shredded, it’d be best to stack trenbolone with the following steroids:

  • Clenbuterol
  • Anavar

Clenbuterol and anavar will help you burn a lot more fat, in comparison to taking trenbolone on it’s own.

If you’re bulking and would like to gain as much quality mass as possible, stack trenbolone with the following bulking steroids:

  • Dianabol
  • Testosterone
  • Deca

A testosterone and trenbolone cycle works extremely well for those who don’t want to retain any water whatsoever; otherwise known as a ‘dry cycle’ or ‘dry gains’. After you finish such a cycle, your weight will pretty much stay the same because your gains will be pure muscle, rather than water weight.

You can throw deca and dianabol in the mix if you want to take your muscle gains up a notch. However, taking these 2 steroids will result in some water retention – albeit not a lot.

I don’t recommend stacking anadrol with trenbolone unless you’re very experienced because these 2 anabolics are pretty harsh on the body, thus extreme caution should be taken when using them in the same stack (especially if you’re a beginner).

You can get legal alternatives to trenbolone, dianabol, testosterone sustanon and deca durabolin in Crazybulk’s bulking stack below…

Trenbolone Side Effects

It’s not all unicorns and rainbows when it comes to trenbolone.

You will build a tonne of muscle and burn some fat, but you’re also very likely to experience some negative effects too like..

  • Increased Blood Pressure
  • Hair loss
  • Insomnia/paranoia/anxiety
  • Less endurance (affects cardio)
  • Tren cough, affects the lungs.

Many don’t know that trenbolone’s also a stimulant, hence how people can suffer from ‘trensomnia’ aka insomnia…as well as anxiety/depression on it. The reason for this is because it becomes more difficult to switch your brain off at night, because you become prone to overthinking everything.

So if you’re struggling with high blood pressure, acne or negative thoughts – trenbolone isn’t something you should be thinking about taking. The reason why trenbolone causes more negative reactions than other steroids, is thought to be because of its high androgenic rating.

Turbocharging DHT to incredible levels is going to come with a few consequences.

Increased Blood Pressure

trenbolone blood pressure

Like other steroids, trenbolone will spike your blood pressure. So if you ARE going to use trenbolone, make sure you have healthy bloods before you start your cycle.

The reason why blood pressure increases on tren is because it raises testosterone levels A LOT. As a result, your LDL cholesterol levels will rise…yep, the bad kind.

…Which then causes your BP to shoot up.

As a result of this change, your actual body temperature may also increase. This is why you can feel warmer and begin to sweat more than usual (particularly in the night).

Aka tren sweats.

Because your blood pressure rises on tren, it also makes endurance-based exercise/cardio more difficult, as your blood isn’t flowing as efficiently.

Hair Loss

Some tren users report some form of hair loss whilst taking trenbolone. I didn’t notice anything personally. However one user (who did) claimed that 80% of it came back after his cycle finished, so this is mostly a temporary side effect.

If you’re very protective of your hair and would hate to see your hair recede or thin; get your hands on a DHT blocker like. However, this may reduce your gains somewhat as your DHT levels won’t be as high.


It is likely you’ll experience some form of insomnia, anxiety or paranoia at some stage on tren. To understand how negatively this will affect you all depends on what you’re like normally.

If you’re an anxious wreck or have bipolar disorder – stay away from tren.

If you’re a pretty normal dude, these mental effects are only likely to be mild; making tren very manageable.

Insomnia can also happen on trenbolone due to the steroid stimulating the nervous system, causing you to be more alert and have racing thoughts in the evening.

Tren cough

And last but not least, the most famous trenbolone side effect of all – tren cough.

This is common when you inject tren acetate and it hits a blood vessel, causing you to uncontrollably cough for around a minute. This is only a temporary side effect and soon passes.


The main 2 side effects of trenbolone are high blood pressure and negative thoughts (mental).

If you can manage both of these potential implications, you’re likely to be one of those guys who loves and swears by tren.

However, if you’ve got mental issues or have had a heart attack in the past, don’t kid yourselves – as your experience is likely to be a negative one.

This is a hugely powerful steroid that can get you ripped AND jacked…it’s just whether you can handle the side effects or not. From my own experience, tren’s side effects do seem a little over-exaggerated in general. However, tren affects each person differently, so extreme caution must still be used.

I think if the wrong person takes tren, life can become an almost living hell. But if you’re a pretty healthy/mentally stable guy, side effects aren’t much worse than other AAS (assuming you’re not overdosing or abusing).

Instead of taking tren we recommend sticking to Trenbolone by Crazy Bulk.
