In this guide, we will be taking a look at Trenavar, an androgenic prohormone known for its fast-acting results and short-cycle duration.
When it comes to massive muscle gains, breaking gym plateaus, and achieving a sharp-edged and chiseled look, many athletes and bodybuilders choose to rely on the use of selective androgen receptor modulators (SARMs) and prohormones.
These types of supplements are highly varied, very complex, and very popular due to the steroid-like effects they provide.
Unlike synthetic anabolic-androgenic steroids, prohormones are compounds that convert into anabolic hormones when metabolized by the body, causing significant effects on the body’s androgenic, estrogenic, and progestogenic receptors.
Depending on what type of pro-hormone you take and which pathway it utilizes within the body, it will determine what kind of effect it will have.
Prohormones that are androgenic will increase aggression, muscle strength, and muscle mass, while estrogenic pro-hormones will increase water weight, increase fat gain, and make breast tissue swell (gynecomastia).
In this guide, we will explore how Trenavar works, what its benefits and side effects are, whether there is an alternative option available on the market, and some commonly asked questions.
What Is Trenavar?
Trenavar, also known as Trendione, or chemically as Estra-4 or 17-dione, is a popular androgen prohormone that was released in 2011 by Innovative Body Enhancement Supplements and PHF Supplements in late 2011.
Unlike previous pro-hormones created to mimic the bodybuilding steroid Trenbolone by converting it into the weaker steroid Dienolone, Trenavar goes above and beyond mimicking the effects, as it converts into Trenbolone after consumption.
The pro-hormone was legally sold over-the-counter up until 2015, when the United States Federal Food and Drug Administration placed a ban on all prohormones.
Although Trenavar converts into Trenbolone within the body and has the same conjugated double bonds, its chemical structure differs in that it has a 17-ketone instead of a 17b-hydroxy function.
When Trenavar is consumed, the 17-ketone will be hydrolyzed into its active form, Trenbolone.
Due to this, Trenavar is considered very powerful, more so than Testosterone, and delivers extremely fast increases in size, strength, vascularity, and muscle gain while maintaining an accelerated fat loss.
How Does Trenavar’s Cycle Work?
Although Trenavar can be used in both bulking and cutting cycles, it is usually used during the cutting phase as it helps individuals by accelerating fat loss and producing lean muscle growth through increased oxygen, red blood cells, and nitrogen.
Despite it not being an actual steroid when consumed, Trenavar is still run on a four to six-week cycle as it has some potential side effects due to being hepatotoxic to the liver.
Trenavar has the same double bonds as its steroid counterpart Trenbolone but differs in structural makeup with a ketone in the 17-position.
This ketone binds with hydrogen in the body, which is what is responsible for converting it into Trenbolone during the metabolization process.
For beginners who are new to Trenavar, the cycle process should begin with a small 10-20 milligram dose per day, split into two intervals throughout the day.
If a beginner starts with a higher dose, they risk some severe side effects like high blood pressure, increased cholesterol, increased aggression, and significant damage to one’s liver.
Advanced users may dose at higher intervals of 30-40 milligrams per day in split doses, with some professionals dosing at around 60 milligrams per day, which is not recommended as the side effects are incredibly harsh.
Even though Trenavar is a non-methylated prohormone, meaning that it has not gone through a form of alkylation and therefore does not use methyls to get into our bodies, it still requires on-cycle support as one’s blood pressure can become extremely elevated during the cycle.
Beyond this, if you notice during your cycle that you have increased puffiness or lactation in the nipple area, it means that you will need to cycle in a prolactin inhibitor (read below about early-onset gyno in side effects).
Once your four to six-week cycle of Trenavar is up, you will need to enter into a post-cycle therapy, as running pro-hormones causes your body to stop naturally producing hormones. Thus, you will need to bring those hormones back up to optimum levels.
If you do not go through post-cycle therapy, you take the risk of losing your muscle gains, as estrogen levels will not be adequately controlled.
When estrogen and testosterone levels are not in working order, you can experience issues with libido, depression, and stress.
What Amount of Dosages Are Appropriate?
Due to how powerful Trenavar is, beginners who are just starting with their first cycle should begin with a much lower dose than experienced users.
Beginners should take anywhere between 10-20 milligrams per day, split into two doses to help minimize the adverse side effects, which are noted below.
Those who are more experienced and can handle the adverse side effects can dose up to 30-60 milligrams per day, split into two doses of 15-30 milligrams.
It is important to note that if you are considering stacking the prohormone, you are going to want to reduce the dosage amount down to 20-50 milligrams, depending on what other legal prohormones you are pairing it with.
If you are planning on using Trenavar as a standalone prohormone, you may be able to up the dosage amount to 50-60 milligrams per day, split into two dosages, but this is only recommended for those who know their bodies inside and out.
Keep in mind, though, that the higher the dosage, the more likely it is that you will experience some severe side effects.
It is highly recommended that a licensed physician is consulted before any supplement intake, including stacks.
Disclaimer: the half-life of most prohormones is six to eight hours.
What Type of Results Should I Expect?
Most users claim that they see a significant increase in both muscle mass and strength within seven to ten days of the cycle.
As the cycle progresses towards the four to six-week mark, most individuals surpass personal gym records and find that they can pump heavier and more sets of iron during training.
Results include a massive boost to overall size, strength, and muscle gains, with accelerated fat loss and increased vein exposure.
Vascularity increases substantially the closer the individual gets to maximum muscle definition. The only negative result is that endurance is entirely crippled.
What Are The Benefits Associated With Trenavar?
Now that you know what Trenavar is, how it works, and what dosages are appropriate, here are some of the benefits you can expect to obtain from taking it.
#1 You Will Have Increased Muscle Mass
Trenavar significantly increases your muscle mass and overall size, giving you a fuller and stronger look.
This is a direct result of increased nitrogen and protein in your muscles, leading to quicker muscle gains.
#2 You Will Get Lean and Ripped When Used While Cutting
Trenavar enhances your metabolism by speeding it up, allowing your core body temperature to stay at higher levels, even while at rest.
This means that you will burn fat, even when you are in your rested state.
Trenavar also does not promote water retention, so you will not become bloated or puffy and will instead look quite lean and ripped.
#3 There Are No Injections Required
Trenavar is taken orally and comes in the form of a capsule or pill. So for individuals who are used to taking steroids, which Trenavar is not, there will be less hassle, pain, and no risk of infection as no injection sites are needed.
#4 It Is Non-Estrogenic
This means that you are less likely to run into problems with fat deposits around the nipples or increased fat gain, as Trenavar does not encourage the conversion of testosterone into estrogen, which is the female hormone equivalent of testosterone.
However, this does not mean that there isn’t a risk of the early onset of gyno if you have problems with your testosterone turning into dihydrotestosterone.
See the adverse side effects below for more information.
#5 You Will Have Increased Strength
You will have noticeably more strength during your workouts.
This is because Trenavar promotes an increase in blood flow, protein breakdown, and nitrogen stores within your muscles, leading to higher levels of strength.
#6 You Will Have Increased Vascularity
Vascularity is the condition in which a bodybuilder or pro-athlete has highly-visible and prominent veins.
This is often positively looked upon in competitions or professional shows, where bodybuilders or pro athletes are expected to have maximum muscle definition.
Those with excellent vascularity are more likely to win in a competition.
Trenavar eliminates excess body fat because it ramps up your metabolism and sucks your body dry of water, and when in combination with increased blood flow, your vascularity visibility becomes increased drastically.
What Are the Side-Effects?
As with all supplements on the market or anything else you put into your body, Trenavar is not without some potentially severe side effects. These can include any of the following:
#1 Increased Aggression
As many can attest, aggression is a bit of a double-edged sword in that it’s not something you want to see displayed in public or in your personal life, yet it is fantastic for pushing through a grueling workout routine.
Increased aggression is shared among users of Trenavar, so you should consider carefully whether or not you will be able to limit your aggression to your gym sessions and not let it follow you home.
Beyond this, when you are at the gym, make sure that you can control the aggression when needed; you don’t want to create an unnecessary scene over a minor misunderstanding or poor communication between you and another gym-goer or staffer.
#2 Dehydration, Headaches, and Soreness
Trenavar increases your metabolism, which leads to an increase in body heat.
This means that your body will start sapping your water reserves, so you will need to double your water intake.
If you are not able to stay on top of your hydration levels, you may experience headaches and soreness in your legs, lower back, and muscles as a result of dehydration.
#3 Reduced Thyroid Levels and Increased Prolactin
Being a pro-hormone, as Trenavar interacts with your body, your thyroid levels will decrease, directly increasing prolactin levels.
Although the effects of this can be countered with prolactin inhibitors, they can include reduced libido, erectile dysfunction, sensitivity and puffiness of the nipples, and lactation.
Adding prolactin inhibitors to your cycles, such as pramipexole and cabergoline, should eliminate or reduce how often these side effects occur.
#4 Reduced Endurance Levels
Due to the strain your body will be placed under, as is the case with all uses of anabolic substances, you will find that your endurance will take a massive hit, making cardio workouts very difficult.
Coupled with leg pain and lowered blood sugar, you may find it hard even to want to start a cardio workout, let alone complete one.
#5 Increased Cholesterol and Blood Pressure During the Cycle
You can expect to see a rapid increase in cholesterol levels and blood pressure as your body processes the Trenavar in conjunction with your food intake.
Trenavar itself will absorb much of that intake into your muscles, leaving cholesterol behind and increasing blood pressure.
These effects should subside entirely once you have finished your cycle.
#6 Potential Strain on Heart and Liver
Due to how potent Trenavar becomes when metabolized into Trenbolone in the body, the sudden spike in blood pressure and unbalanced cholesterol levels can put a considerable amount of strain on your heart.
In addition to this, Trenavar is very toxic to your liver, which means you need to avoid consuming any alcohol and always follow up with on-cycle support to relieve the stress from your liver.
#7 Insomnia, Fatigue, and Lethargy
Due to the amount of strain that Trenavar puts on your organs and soft tissues, you will experience a drastic reduction in endurance capability.
This can leave you feeling very fatigued and lethargic.
#8 Decreased Blood Sugar
High levels of intense training while taking Trenavar can cause all of your carbohydrate intake to be redirected to your muscles.
This, in turn, if you are not consuming enough, can cause you to enter the early stages of hypoglycemia due to decreased glucose levels.
This is a direct result of substantial changes in your body composition and blood chemistry.
If this occurs, you may experience sweats, dizziness, and severe fatigue.
#9 Increased Chance of Gynecomastia
Trenavar reduces your thyroid levels, which, in turn, increases your levels of prolactin.
Too much prolactin and your body can create puffy and sensitive nipples, which are a hallmark of early-onset gynecomastia.
#10 Hair Loss
When testosterone is converted into dihydrotestosterone, your hair follicles become much more fragile, and your scalp may become too dry to produce enough hair.
This can lead to significant hair loss as your skin will not be able to keep the hair that you do have, intact.
Is There a Natural Alternative?
Yes, there is, and it is called Trenorol.
This oral supplement is manufactured and sold by CrazyBulk, an online supplement manufacturer based in the United States.
The company wanted to bring natural and legal steroid alternatives to the market so that bodybuilders and athletes could achieve their physique goals without compromising their health and, thus, created Trenorol (among others), a Trenavar alternative.

How Does Trenorol Work?
Trenorol, also known as Tren, is used for mass muscle gains regardless of whether you are in the bulking or cutting phase and provides these muscle gains through the re-creation of Trenbolone-like androgenic effects.
You can expect to have faster healing, stronger workouts, access to more power, and greater muscle growth due to how it works.
Trenorol works by enabling your muscle tissue to retain higher levels of nitrogen. This is important as your muscles need to remain in an anabolic state, but when you vigorously exercise, you deplete your nitrogen stores.
When you do not have enough nitrogen, your muscles are unable to process protein efficiently.
To put it simply, the more nitrogen you have in your muscles, the more protein your muscles have access to, which means accelerated muscle gain growth and accelerated fat loss.
Trenorol also boosts your red blood cell production, allowing extra oxygen into your muscles, which is what gives you that extra strength and power during workouts. Having this extra oxygen also ensures that your muscles can repair during your recovery downtime.
How to Use
To use Trenorol, you take three capsules per day about forty-five minutes before your workout. On days that you are not working out, you take one capsule with every main meal or three per day.
Always take with water and make sure you are consuming a healthy and balanced diet.
Generally speaking, results are typically seen after two months of regular use. After two months of daily use, it is recommended that you take week-two weeks off before starting again.
What Are the Ingredients?
The ingredients include 600 milligrams of Beta-Sitosterol, 300 milligrams of Samento Inner Bark, 300 milligrams of Nettle Leaf Extract, and 75 milligrams of Pepsin.
Beta-Sitosterol (also known as a plant sterol ester), this ingredient can be found across a wide array of vegetables, fruits, nuts, and seeds.
It works by lowering cholesterol levels, treating chronic fatigue, and limiting the amount of testosterone that gets converted into dihydrotestosterone (DHT), which ensures that your testosterone levels stay high and your estrogen levels stay in control.
Samento Inner Bark
Samento Inner Bark (also known as cat’s claw), this ingredient is often used with individuals who suffer from rheumatoid arthritis and osteoarthritis. It aids the body by reducing inflammation levels, fighting fatigue, and boosting your body’s natural healing process.
Nettle Leaf Extract
helps in circulating testosterone around the body by preventing it from binding with sex hormone-binding globulin.
Beyond this, the nettle leaf extract is abundant in iron, which helps produce hemoglobin; it reduces oxidative stress, relieves pain, and decreases inflammation.
is a digestive enzyme that breaks down protein molecules into compounds with two or more amino acids.
When taken as a supplement, pepsin allows the protein to work faster, and it boosts nitrogen retention.
Can You Stack It With Other Legal Steroids?
Trenorol is the key component in CrazyBulk’s bulking, strength, and ultimate stacks.
If you choose to not go with any of the stacks offered by CrazyBulk, it is recommended that you stack it with Winsol, Clenbutrol, Testo-Max, Anadrole, D-Bal, and DecaDuro.
However, you do not have to stack it as it is quite a capable standalone supplement.
Are There Any Side Effects of Using Trenorol?
Trenorol uses only natural ingredients, so there are no known side effects.
As with any supplement on the market, it is wise to be cautious when using it, especially if you have existing health problems that require medication.
It is not recommended for women who are pregnant or nursing, and its use should be cleared with your doctor.
Pros and Cons
In terms of the positives, you will be able to increase your muscle mass, have improved strength, endurance, and stamina, and will find that you will lose fat at an accelerated rate without losing muscle in the process.
Regular use of Trenorol can also help promote vascularity.
In terms of the negatives, it can only be found online through one manufacturer, it is priced at a premium, and it can take a long while to ship.
Is Trenavar Legal to Purchase and Consume?
The legality of purchasing and consuming Trenavar is dependent on the country you reside in and what the specific laws of your country are concerning the use of metabolic enhancing drugs.
Although Trenavar used to be sold over the counter back in 2012, it became banned in 2015 within the United States as the United States Food and Drug Administration enforced a ban on all prohormones.
However, if you reside in a country like the United Kingdom, which has more liberal views on the use of pro-hormones and steroids, you may be able to purchase, import, and use them for your gain legally.
Now, Trenavar can be found and bought online through websites such as eBay.
However, you must adhere to your country’s laws before purchasing, as illegal purchases, as such, can bring about a lot of risks to yourself.
Presently within the United States, Trenavar is only available to those within the veterinary field, as it is commonly used to add both size and mass to cattle (used in its Trenbolone-17beta, Trenbolone-17alpha, and Trendione forms) before their demise.
Is Trenavar Considered a Steroid?
Trenavar is classified as a pro-hormone and not as a steroid itself.
A prohormone is a substance that an individual takes to directly impact hormones within their body (as prohormones must be converted by the body).
With this said, it’s easy to see why there is a lot of confusion surrounding this topic because the name, Trenavar, is a combination of two known steroid names, Trenbolone and Anavar.
When taken in its oral form, Trenavar is not a steroid, but when metabolized by the body, it gets converted into its active form, Trenbolone.
Trenbolone, unlike Trenavar, is an anabolic steroid that must be injected into the body.
The effects that Trenavar has are comparable to Trenbolone, in that the user should expect a massive boost in size, strength, vascularity, and accelerated fat loss.
How Long Should a Cycle of Trenavar Last?
The average cycle is anywhere between four and six weeks.
However, it is strictly recommended that individuals do not use Trenavar for longer than thirty days due to its high toxicity levels.
The liver has a tough time processing it, which can lead to some serious and very harsh side effects.
A lot of individuals find that by the time the third week has rolled around, the side effects can become extremely aggravating, so much so that taking a couple of days off to break the cycle a bit helps.
What Is The Difference Between Trenavar vs. Trenbolone?
Trenavar is classified as a pro-hormone and is taken orally, while Trenbolone is an anabolic steroid that must be injected into the body.
In terms of chemical makeup, Trenavar does have the same double bonds as Trenbolone but differs in that it has one ketone found at the 17-position instead of a 17b hydroxy function.
The 17-ketone gets targeted by the 17b-hydroxysteroid dehydrogenase type 5 (17b-HSD5); it gets hydrogenated into its active form, Trenbolone.
What Is The Difference Between Trenavar vs. Superdrol?
While Trenavar (Trendione) is a pro-hormone derivative of Trenbolone, a synthetic anabolic steroid, Superdrol is a pro-hormone derivative of dihydrotestosterone (DHT).
Superdrol (Methasterone) was created in the 1950s, was never commercially available, and only became available to the black market as a designer steroid.
Known as Superdrol, which is the brand name, this pro-hormone has a half-life of 6-8 hours and requires a lower dose than Trenavar at 10-20 milligrams on a four-week cycle.
The results are an explosive strength gain of 25% and a 2-3 cm gain in mass size.
Like other prohormones, Superdrol will cause liver damage if abused, will cause water retention, and will suppress natural testosterone levels, and as such, post-cycle therapy is required.
Some users have also noticed appetite suppression, acne, shin splints, lethargy, and libido loss while on it.
Unlike Trenavar, Superdrol has a lower androgenic activity level, decreasing one’s risk of experiencing hair loss, hair growth, acne, and other serious side effects.
How Long Does It Take for Trenavar to Kick In?
Due to how powerful Trenavar is, about ten times more androgenic than testosterone, you are going to see transformative results in as little as seven to ten days.
This is why the cycle period tends to be so short because, by the time you hit that ten to twenty-day mark, you’re going to be feeling the adverse side effects.
Can I Stack Trenavar With Any Other Types of Pro-Hormones?
Yes, Trenavar can be stacked with other types of prohormones.
If you choose to stack it, the average dosage must be changed to reflect the stack.
Generally, individuals will stack it with other pro-hormones like Epistane, Equipoise, Primobolan, and Testosterone.
If stacking, the recommended dosage is between 30-40mg/day split into two intervals daily.
What Is Trenavar Post Cycle Therapy?
Even though Trenavar does not have any estrogenic side effects, it is still mandatory to go through post-cycle therapy after cycling off at the end of your four to six weeks.
The reason being is that while on Trenavar, your luteinizing hormone, follicle-stimulating hormone, and other thyroid-related hormones will be suppressed, leading to PCT as a necessary option for bringing your hormone levels back up to standard numbers.
Beyond this, post-cycle therapy is recommended as it will help your soft tissues and organs recover from Trenavar’s toxicity, and it will help your body recover from any damage done during the cycle.
If you choose to not go through with a post-cycle therapy, not only do you risk losing your muscle gains as your hormone levels will not be functioning at optimum levels, but you can experience side effects from low testosterone and high estrogen levels, like libido loss, depression, and gynecomastia.
Although Trenavar carries some significant benefits for pro-athletes and bodybuilders alike, it can be extremely hazardous to one’s health if not monitored closely.
For those who want to still gain significant muscle mass and strength without the potential for serious side effects, Trenorol is a compelling alternative made with natural ingredients.
It has the same function as Trenavar but keeps both your blood pressure and glucose levels normalized.
