Tren cycle: trenbolone (the good, the bad, & the ugly)

The idea of using a Tren cycle to rapidly accelerate a bodybuilding physique isn’t new.

The idea of even using steroids (in the first place) to increase muscle mass isn’t new.

Way back in the 1940s, people were already taking advantage of this trend and the underground popularity of anabolic steroids has only grown since. In this article, we’re going to talk about the Granddaddy of them all, the steroid to literally end ALL steroids….TRENBOLONE.

You’ll know why this is by the end of the article.

Trenbolone a synthetic steroid that’s often used by bodybuilders for its ability to help them bulk up quickly. What are the benefits? What are the potential side effects? We’ll discuss everything there is to know in this article.

What is Trenbolone?

Trenbolone is a synthetic steroid compound that can be administered via injection, pellets or other topical means. It’s mostly used by those in the bodybuilding community to improve their muscle mass and tone as fast as humanly possible.

Trenbolone’s extreme popularity amongst professional athletes comes from its ability to help muscle development faster.

Trenbolone or ”Tren” for short, is a direct derivative of Nandrolone, more often reffered to as Deca Durabolin. The main difference is a slight change in the chemical makeup. This chemical alteration is significant enough that it produces a different impact on your body. Any steroid user or bodybuilder thats ever used Deca knows just how powerful it is, so its clear now, right out of the gate why Trenbolone is also so powerful.

Tren is widley considered better than Nandrolone, for a couple reasons: it attaches to your androgen receptors better, and it metabolizes slower.

The biggest benefit to Trenbolone is that its a non-aromatizing steroid. This means, unlike Testosterone for example, you won’t have high estgrogen conversion, which is especially helpful during the post cycle time period.

Abnormally high estrogen is what leads to the dreaded ”gynocemastia”, as well as lethargy and huge drops in mood and energy levels. This benefit is uncommon as most anabiolic and androgen compounds have this estrogen hike effect, so Tren shines in this regard.

Many choose Trenbolone for its impeccable ability to give you razor-sharp definition and a cut phsyique. The lack of estrogen conversion, and water-retention also means there is no water ”bloating” effect.

Note that if and when Tren is combined with an aromatizing steroid…then water-retention and estrogen conversion will still occur from this other steroid, so a proper PCT regimine is still needed.

Max’s Note: For a real, NO-BS info-packed guide on cycling steroids, then grab your digital E-Book copy of ”Straight From The Underground” by John Doe Bodybuilding. This is my #1 recommended underground handbook on EVERYTHING related to steroids. Everything in this book is based on real first-hand experience, instead of theory.

Trenbolone Forms:

Trenbolone Acetate vs Trenbolone Enanthate vs Parabolan (Tren-hexahydrobenzylcarbonate):

Trenbolone can be administered in 1 of 3 forms. Those are either: acetate, enanthate or parabolan. Acetate has a shorter half-life than the other two forms. Enanthate takes longer to act but its effects last for much longer periods of time, and Parabolan has a VERY long half-life.

See this chart for an overview of each:

Tren AcetateTren Enanthate (Trenabol)Tren-Hex (Parabolan)
Typical cycle lasts between 8-16 weeks.Typical cycle lasts between 8-16 weeks.Typical cycle lasts between 10-14 weeks.
Dosage is usually 100-200mg per week, usually split into two daily doses.Dosage is usually 100-300mg weekly for a beginner to intermediate user.Dosage is usually 150-250mg weekly for a beginner to intermediate user.
Considered the MOST potent of the three.Tren E is useful for both bulking & cutting.Tren Hex is optimal for bulking, strength & lean mass gains, also powerful for fat loss & cutting.
Short half life of only 2-3 days.Long chain form of Tren.14 day half life, so much longer half-life & therefore requires less injections.
Most commonly used form of Tren.Significantly boosts protein synthesis, & enhances nitrogen retention.5X as powerful as Testosterone, so notably higher risk of side effects.

Trenbolone, in all its forms, was developed to be a ”prodrug”, which means its not in an active form UNTIL its put into your body, where its then converted to its active form.

Tren Acetate orginially was designed for use in veterinary setting to increase cattle muscle size. It’s half-life is only 2-3 days. Acetate is the most potent of the three Tren esters, possesing the largest quantity of active tren (per each 100 mgs.).

Short-acting steroids always require more injections per week, in this case every other day being the most frequent dosing schedule. Despite being the most potent, Acetate is the most widely used form of Trenbolone.

Tren Enanthate carries a 7-day half-life, and can be found on the black market. The Enanthate form of Tren, is slower-release, but is known to carry all the same benefits one would expect from Trenbolone: enormous jump in endurance, muscle definition and mass, and excellent retention of nitrogen.

Finally, Tren-Hex or ”Parabolan” has the longest half-life (slowest-release) of 2 weeks (14 days). Parabolan was ceased of production in the late 90’s. Despite its slower-release, its considered just as effective as the other two forms of Tren.

One form of Tren should NEVER be stacked with one of the other two forms of Tren, as doing this would multiply its side effects, and as you’ll see below, these side effects are intense enough already (to begin with). Its perfectly fine and common however, to strategcially combine Tren with other steroids. Recommnedations for this you’ll find below.

TREN ACE (Trenbolone Acetate) CYCLES:

Acetate is an incredibly FAST release form of Tren. Its absorbed very quickly in your blood, giving it only a 3-day half-life. This feature (how quickly its absorbed) usually comes down to the personal prefrence of the person using it. Beyond this, there’s really no difference in what you can expect from it.

Tren is known for its amazing ability to give you an enormous boost in strength, sharp muscle definition, and very fast results. Each of these you can expect from the Acetate form of Tren. Unfortunatley, it also carries adverse effects as well, the main ones being: night-sweats and resulting insomnia, a jump in LDL cholesterol, acne, possible gyno (from progestin), and accelerated baldness (for those already prone to it).

If you’re just starting Tren for the 1st time, then 200 mg. per week is the highest recommended dose. Even 100 mg. per week is often enough for a beginner. Typical Acetate cyles range from 8-15 weeks, which is enough to give you outstanding results.

For those more experienced with Tren, this dosage can be upped to as high as 500 mg. per week (absolute MAX), assuming you’re acutley aware of Tren’s reported side effects (and you’re prepared for them).

TREN E (Trenbolone Enanthate, OR ”Trenabol”) CYCLES:

Tren Enathate or ”Trenabol” has a longer-acting release, and is derived from the nandrolone anabolic-androgenic steroid. This form of Tren, just like the other two, is commonly stacked with Testosterone to compensate for the drop in your body’s natural testosterone levels.

Used primarily for both cutting and for bulking, Trenabol is known to give fast recovery, more oxygen to your muscles, and better IGF-1 function. Of course increased endurance, and better nitrogen retention are also effects to expect from Tren Enanthate.

All the same negative effects Acetate carriers, are also present with Enanthate.

Cycles of Tren Enanthate typically range from 8-15 weeks, with 1st time users dosing anywhere from 100-300 mgs. per week. Most beginners find even this range to be extremely effective. Those with more experience often up this dose to as much as 500 mg./week.

Tren Cycle examples:

Tren Cycle For Bulking

A Tren cycle is popular for bodybuilders who want to bulk up in the weeks and months leading up to competition. The typical bulking cycle lasts 12 weeks with a dosage that ranges from 200-400mg a week. Winstrol and a Testosterone ester are often added to the last few weeks of Tren cycles.

Tren Cycle For Cutting

Tren Acetate is almost always the go-to Tren form for cutting cycles. The same dosage used for bulking, is often also used to cutting, though experience users sometimes choose to go higher.

75-100 mgs. two to three times a week for a month, then increasing this range to between 100-150 mgs (for weeks 5-12) is a solid cutting cycle for Tren. Acetate leaves your body quickly so a higher frequency of injections will be needed.

12-week Tren/Test/clenbuterol Cycle (example):

This cycle would requires injections every week for 12 weeks:

Week’s 1-12:  50-75mg/day Trenbolone Acetate, 0.5mg/eod Arimidex, 50mg. a day of Test Propionate. If you need to, you can take a dopamine antagonist like Dostinex, for example, taken during your cycle to reduce your prolactin.

Week’s 1-12: Add 80-120mcg/day of Clenbuterol (optional).

Week’s 9-12: Add 40mgs./day of Halotestin for maximizing the rock hard feeling of your muscles (optional).

Post Cycle Therapy: begin this 3-4 days after injecting your last shot, 100mg./day Clomid for 10 days, then continue but lower it to 50mg./day for another 10 days (or use Nolvadex at 40/40/20/20).


None of what you read on this site is medical advice, but its still highly advised that Trenbolone be avoided until you acheived somewhat significant experience with steroids. There are many advanced steroid users that still avoid Trenbolone even at advanced stages.

There are several reasons for this.

Tren can have serious risks to your long-term and short-term health, not to mention nasty side effects. Many steroid users now consider Trenbolone to not be worth these risks, as its considered unpredictible overall. There ARE alternatives, and if you’re asking me, I’d consider them, strongly.

These alternatives can give you extremely similar results (the good ones), to Trenbolone itself, while avoiding the terrible effects Tren is notorious for. THE #1 alternative to Trenbolone availible today, is without a doubt TBULK.

TBULK is an extremely strong aternative that mimics all the good charactistics of Trenbolone, while steering you away from its bad health risks. It should be noted its also 110% legal for use in all countries.

I have more than several reasons why I commonly endorse TBULK as the absolute BEST Tren alternative. If i had to narrow it down however, to one or two reasons, it would be:

Its incredible ability to build FAST muscle, power, and strength, with NO bloating or water retention, giving you an absolute shredded, ripped, and cut phyisique.

This is why even many advanced steroid users and bodybuilders, are choosing TBULK with unbelievable results (and ZERO side effects). Tren-like results, without all its debilitating side effects, TBULK is the absolute best alternative to the very risky Trenbolone.

TBULK is highly recommended.

Tren Cycle pct:

It could take up several weeks for your hormone and sperm production to return to normal, so with Tren you’ll NEED a Post Cycle Therapy (PCT) program after your cycle ends. This will also help you keep your gains, just like with other PCT protocols.

So the primary 2 aims of a Tren PCT is to 1) Return your testsoerone production to normal levels, and 2) Keep your gains. Tren can shut your testosterone production off entirely, so don’t neglect the PCT component.

Finding the right PCT for you personally will likely take a few cycles to get just right. This is normal so be patient with yourself.

If you’re using Tren Acetate, then its best to start PCT 3 days after the last injection, and continue it for 4 weeks.

Here’s an example of a PCT protocol to consider:

  • Week 1:  Nolvadex 20mg./day, Clomid 100mg.
  • Weeks 2 -3: Nolvadex 20mg./day, Clomid 50mg.
  • Week 4: Nolvadex only at 20mg. a day

You might notice HCG was not included here, although you can combine all 3, HCG doesn’t have to be included alongside an AI and a SERM.

There are of course other combinations (ex. either using AI’s or SERMS), but this example hopefully simplifies it for you.

The PCT program should be continued until your levels have normalized and sperm production has resumed.


Trenbolone is not usually recommended for those new to anabolic steroids, due to its strength and common side effects, but if we had to choose a regimine for you, it would look like this: 200 mg. a week, for 10-12 weeks is long enough to give you an idea of what to expect from it, both good and bad. Sometimes different people react to the same anabolic steroid differently.

This protocol is enough that you should be able to gauge your tolerance to it.


Intermerdiates can up their dose to the 250-500 mg. a week range, for a cycle lenth of 10-12 weeks. One other steroid can be stacked with this like Testosterone Enanthate OR Test Propionate, for example (12 weeks).


For those more advanced, users have reported dosing as high as 750-1,000 mg. a week, for 12 weeks. Going over 1,000 mg. would not be wise, and is considered insanely high (for Trenbolone).

Common advanced cycles run for 12 weeks, and sometimes have users running a lower dose the 1st 6 weeks, and higher the 2nd 6 weeks. In additon to this, Anavar is sometimes added at a lower dose of 100 mg./week, as well as Testosterone Propionate at 1,000 mg./week.

Trenbolone Results:

Trenbolone is versatile enough that it can be used for either cutting OR bulking. If you’re looking to cut, then Tren Acetate is your best option. If Acetate isn’t availble to you, then Enanthate still does the job very well. Keep in mind Tren with Tren you’ll have no water-retention.

Tren is able to provide these effects due to its capability to increase your lipolysis. Lipoysis is what allows fat to to stored as energy, which therefore means you burn fat instead (and grow muscle faster). This process happens rapidly with Tren, due to its sheer potency.

· Builds muscles faster. Every bodybuilder is different so the effects of Trenbolone will vary. Some people may be able to build muscle at a faster rate, while others can increase their strength levels in just two weeks.

· Increased nitrogen retention. This will help your muscles recover from workout, grow, and appear bigger.

· Enhanced IGF-1 levels. IGF-1, which is short for ”Insulin-Like Growth Factor 1” will get raised due to your androgen receptor activty receiving an anabolic-impact. IGF-1 1 is crucial in order to recover from workouts, as well as many other bodily functions. Enough of this can help your muscles grow at a very fast rate.

· Improved food uptake & faster recovery. Trenbolone can help your body use nutrients more efficiently and speed up the recovery process.

· Increased protein synthesis. This is an advantage because it helps you build muscle at a quicker rate. When protein synthesis is increased, your body becomes more anabolic in the sense that your muscles just recover faster. You also cut stored fat weight much quicker and easier. This fat is what’s used for energy, which allows you to retain more muscle.

Side Effects of the Trenbolone Steroid:

There are intense side effects historically associated with Trenbolone. These are more common when its not being used properly.

Tren E is believed to have the least number of side effects, though not everyone agrees with this view, and it hasn’t been verified. Always keep in mind that most side effects show up as a response to an individual’s tolerance to a drug. Below are the primary side effects Tren has been associated with:

The most common side effect reported with Tren can potentially include:

  • Hair Loss – Male pattern baldness is an effect of the androgenicity of the most steroids. Tren is among the types of gear that can speed this process up in men who’re genetically predisposed to it.
  • Aggression and rage – Tren can turn on otherwise relaxed, calm mood into one of absolute rage, untrollable anger, and emotional bursts. It should go without saying, that this is of the more serious side effects as it could affect your life negatively (employment, friendships and replationships, etc.). Its absolutley imperative that you keep a very close eye and grip on this one.
  • Tren Flu – The ”Tren-Flu”- Flu-symptoms, if experienced, will cause you to feel weak and lethargic. The Tren-Flu sometimes catches those new to Tren off guard, so keep an eye out for this to avoid losing precious workouts and your diet regimine. Hot and cod sweats, night sweats, shakes, lightheadedness, nausea, congestion, and running sineses are common flu-like symptoms.
  • Tren Cough –One of the more well-known potetial effects. Tren can interfere with your respiratory system (a result of its fat-buring capability). Essentially: small levels of oxygen can enter into your bloodstream, which can become dangerous. Blood vessels get restricted in your lungs, leading to a coughing fit. Right after injection, this cough can surface out of nowhere. Usually goes away after 30-60 seconds.
  • Hypogonadism & Erecticle Dysfunction – This effect can occur as a result of the suppression of your natural testoserone levels. This can be largely, if not entirely avoided by way of a proper PCT plan. Many men also choose to add Testoserone to their stack while on their Tren cycle, which also helps avoid this problem. Keep in mind that the higher your Tren dosage is, as well as the longer your cycle duration, the worse ED, lowered sperm count and libido issues will be (generally speaking).
  • Oily skin & acne – Androgenic and anabolic steroids all carry the risk of raising sebaceous activity in your skin. This process creates oily skin, which can cause acne to those genetically-disposed to it. Skin, as well as your hair are both affected by increased sebaceous activity.
  • Heart Attacks – Though not common, and certainly more than just a steroid side effect, it can not be ignored that a clinical trial has shown heavy Tren use can cause cardiovascular problems. The primary study pointing to this evidence would be this one, which examines how Trenbolone Acetate contributed to the heart attack of 23 year old.

Some people can experience tremors or even stroke when using Trenbolone for prolonged periods of time, at a higher dose than is recommended.

As mentioned, the biggest plus with Tren is that (unlike other AAS steroids), it avoids water retention issues since its not estrogenic.

Common FAQ Related to Trenbolone:

Is Trenbolone illegal?

Trenbolone is a Schedule III controlled substance under the Controlled Substances Act in the United States, and also is illegal for use in most other countries around the world. No form of Tren is currently used clinically for human beings. Only veterinary use is approved in certain countries.

Trenbolone enanthate is only found on the black market, its no longer approved for any type of use. Trenbolone is illegal then, for any kind of use as an anabolic steroid and is subject to sanctions by all associations.

Does trenbolone cause hair loss?

Yes, Trenbolone can cause hair loss. See my points above under the side effects section.

Does Trenbolone give you a lot of muscle?

YES, it helps build up your muscles at almost an alarmingly fast rate when used properly and at the correct dose. The side effects can potentially outweigh the benefits if abused or overused though.

Does trenbolone make you aggressive?

Yes, trenbolone will make you more aggressive.

What causes Tren cough?

Tren cough is known a side effect of Trenbolone, though its not guaranteed to happen. It’s the result of an irritation in your throat and lungs from too much use or abuse of trenbolone, which causes you to sound like you’re straining to breathe with coughing spells.

What is the best way to stack Tren for a beginner?

If a beginner should consider not stacking Trenbolone with any other steroids, due to its sheer strength. The best approach for beginners is to start slow and increase the dosage slowly as your body adjusts.

Trenbolone is an advanced-level drug and has many side effects that need to be taken into consideration before use.

Can women use Trenbolone?

No. Absolutely not. Trenbolone is a male hormone only and has no place in female bodybuilding.


Trenbolone is a powerful drug that has many benefits for bodybuilding, but should only be used by advanced level athletes who have enough experience with not just Trenbolone, but several other types of steroids.

Recommendation? I recommend it to those looking for more aggressive results in their muscle gains and fat loss.
