RAD140 (Testolone) Review, Results, Dosage | April 2024

Table of Contents

This will be an in-depth article about RAD140, also known as Testolone. We will go over the recommended dosages and cycle length, benefits and side effects that you could expect from this compound.

RAD 140 (Testolone) Rreview

Let’s start off by explaining what RAD140 actually is.

As we said, RAD140 is a SARM (Selective Androgen Receptor Modulator).

Testolone is currently in development (clinical trials, studies, etc.) to one day treat muscle wasting diseases and to treat breast cancer.

It is getting a lot of popularity among professional athletes and bodybuilders because of the incredible benefits of increased muscle mass and increased strength.

Let’s explain how RAD140 actually works.

How Does Testolone Work

It works in a very similar way to the way steroids work. The difference is that Testolone selectively targets the androgen receptors to bind to. Steroids, on the other hand, don’t selectively target and because of that, they cause a lot more side effects.

So RAD140 selectively targets androgen receptors to bind to. More specifically, it targets the androgen receptors in our muscle tissue and skeleton. Because of that, it has great benefits of increased muscle mass and fat loss (we will go over the benefits later).

Is RAD140 Legal

Currently, RAD140 is legal to buy and use in every country in the world, with the exception of Australia (we will go over the situation in Australia later in the article).

Testolone is sold under the labels of “Research Chemical” or “Not for human consumption” because it’s not FDA (Food and Drug Administration) approved yet. Because of that, companies have to sell RAD140 under these labels. But in a few years, once RAD140 is finished with clinical trials, it will likely be FDA-approved.

If you want more information on the legality of RAD140 and other SARMs, read our article where we give an in-depth answer to the question; are SARMs legal?


As we said before, the laws regarding RAD140 legality are a little different in Australia from the rest of the world.

Basically, you aren’t allowed to use Testolone in Australia without a doctor’s prescription.

However, a lot of Australians use RAD140 regardless and none of them seem to get in any trouble. Nobody will ask you if you have a doctor’s prescription or not.

You can read more about this in our article on Australia SARMs.

RAD140 In Sports

Because of the obvious unfair advantages (increased muscle mass, strength) that RAD140 gives, it’s prohibited by almost all sports bodies including the Olympics.

RAD140 is banned by the USADA (the United States Anti Doping Agency) and the WADA (World Anti Doping Agency).

Don’t use this compound if you are a competing professional athlete.

A lot of CrossFit athletes have recently been caught using RAD140 for strength.

RAD140 Benefits

A lot of people use RAD140 because of how great its benefits are. This compound is very powerful and is known to help users put on a lot of lean muscle mass and shred off fat.

The benefits of RAD140 are:

  • Increased muscle mass
  • Fat loss
  • Increased strength
  • Vascularity

Let’s go over each benefit and explain it in detail.

Increased Muscle Mass

Testolone is known to be one of the SARMs that makes you put on a lot of muscle during a cycle. Similar compounds would be LGD 4033YK11 and S23.

People who take RAD140 report that taking this compound will make you easily gain 8lbs of muscle. A lot of people who were beginners or intermediate lifters even gained over 12lbs of muscle in an 8-week cycle.

On my Testolone cycle, I gained about 7lbs of muscle mass. My results are easily achievable if you have pure, high-quality Testolone.

Remember, the results will be great if you make sure that your diet and workouts are on point.

Fat Loss

This is also one of the great benefits of RAD140. Not only will you gain a lot of muscle mass, but you will also very effectively lose fat even when eating at maintenance calories.

In fact, Testolone is famous for its incredible body recomposition ability. This means that you won’t gain a lot of weight but you will switch your fat to muscle.

To get the most out of RAD140, eat at maintenance calories. You will be able to lose a lot of fat and gain a lot of muscle mass.

On average, I can confirm this myself, people lose about 3-5% of their body fat. I went from 17% body fat to 12% over the course of my RAD140 cycle.

Increased Strength

This benefit is what RAD140 is infamous for. The strength gains are absolutely incredible, probably one of the best among all SARMs.

In my experience and according to other people, RAD140 is one of the best SARMs for gaining a lot of strength. This is also why a lot of competitive CrossFitters are using this compound.

You will feel stronger almost instantly and all of your lifts will increase week after week. Testolone is amazing for breaking strength plateaus.

Most people gain 25lbs on all of their major lifts (bench press, squat, deadlift).

The best thing about this is that you will be able to keep most of your RAD140 strength gains after the cycle is over if you train hard. Obviously, if you quit training after the cycle, your strength will go down.


When I was taking Testolone, my bench press went up by 40lbs, squat by 50lbs and deadlift by 55lbs. All of this in an 8-week cycle, it was insane.

Keep in mind, the strength gains, as well as muscle increase and fat loss, are dependant on how hard you train and how clean your diet is.

Lean, Dry Muscles And Vascularity

This is more of a cosmetic benefit of RAD140. A lot of people report a leaner look with incredible pumps in the gym. Vascularity will also increase for most people when they take Testolone.

RAD140 Side Effects

RAD140 is a well-researched chemical with still ongoing clinical trials and a lot of people who are reporting the benefits and side effects.

The side effects of Testolone are:

  • Aggression
  • Suppression

Let’s go over each side effect and explain it in detail.


Some people report a noticeable increase in aggression but this is actually an individual thing. Everybody is different and some people seem to have increased aggression when taking this compound.

The good news is, most people won’t see this side effect. I was taking RAD 140 for 8 weeks and never had this side effect.

Testosterone Suppression

RAD 140 will cause a reduced natural production of Testosterone in our bodies. The extent of the suppression is dependent on mostly how pure our product is. This is why it is so important to have quality products.

Overall, Testolone’s suppression isn’t that bad and you will easily recover naturally in a few weeks after the cycle. You definitely won’t need a PCT (Post Cycle Therapy) to recover, as long as your compound is pure. We will cover the topic of RAD140 PCT later in the article.

Some companies spike their SARMs with prohormones. This will make our suppression very bad and could even cause other side effects, such as hair loss, that Testolone wouldn’t otherwise cause. I buy my Testolone from these companies and had great results with no problems and had low suppression that recovered naturally in a few weeks.

Other Side Effects

Some people experience weird side effects from their RAD140 such as hair loss, headaches, stomach aches, etc.

This is very weird because RAD140 is well researched and we have a lot of data from human trials and studies available.

So the reason why some people get weird side effects is that their Testolone is bunk.

Sadly, a lot of companies sell bunk RAD140 and other SARMs that have other substances mixed into the product. These substances can cause a lot of weird side effects and make the product a lot less safe. This is why it’s so important that you buy high-quality, pure RAD140.

RAD140 Half-Life

From numerous research results, we know that the half-life of Testolone is 24 hours.

This means that we should take a dosage of RAD140 once every 24 hours to keep the levels of the compound in our body optimal. If we do this, we will make sure that Testolone will work at full capacity throughout the cycle and this means great results.

RAD140 Dosage And Cycle Length

People imbuing RAD 140 recreationally usually take a dosage between 5mg to 30mg per day for eight weeks in total.

While there is no established human dosage for RAD 140, the safest dosages seem to linger between 5 to 10mgs per day

In our in-depth RAD 140 dosage guide we go over the best and safest cutting and bulking Testolone dosages as well as the dosages used in human trials. If you’re interested in that, please go check it out.

I also recommend that you don’t extend your cycle beyond ten weeks, as to avoid heavy side effects.

Regarding PCT, If you use 5mgs of RAD 140 for 8 weeks, it’s very likely you won’t need any.

Dosages higher than 5mgs per day will most likely require PCT, please read the next section for a more in-depth look into the matter.

Testolone PCT

A lot of people think RAD140 requires a PCT. The truth is, PCT (Post Cycle Therapy) can have serious side effects on its own so it is a lot better to just recover naturally in a few weeks. Testolone will definitely suppress you to some extent but it is really not that bad to require a PCT as S23 does.

If you have real, high-quality Testolone, you 100% won’t need a PCT and will recover your Testosterone production in a few weeks after the cycle.

Stick to normal dosages and normal cycle length as well as make sure that you have real, high-quality RAD140 and you 100% won’t need to do a PCT.

You can read more about this in our article about PCT for RAD140.

RAD140 Before And After

Let’s go over some before and after photos and see what kind of results we can expect from Testolone.

We will go over two before and after results. For more of these, check out my RAD 140 before and after article where I list 8 amazing Testolone results with before and after photos.

Results #1

RAD140 before and after

Results like this are pretty average from RAD140. I’d say that most people can easily achieve this on their Testolone cycle.

The person on the picture gained about 5-7lbs of muscle and maybe lost 1-2% of his body fat.

You will easily achieve results like this with this compound.

His cycle:

Week RAD140 PCT
1-8 10mg a day /

Results #2

Even though there is a difference in lighting in the pictures, the results are amazing.

He probably gained about 10 lbs of muscle and lost 2-3% of his body fat.

You can definitely expect to get results like this, as long as you train very hard throughout your cycle.

His cycle:

Week RAD140 PCT
1-8 15mg a day /

My Testolone Experience

I did a cycle of RAD140 this past winter (winter of 2019-2020). I have decided to add Cardarine to the cycle, to help me lose even more fat and help me train for longer (a benefit of Cardarine). And besides, Cardarine is non-hormonal, so adding it to a SARM cycle doesn’t really change anything.

I am really happy with the results that I got from this cycle. I gained about 6lbs of muscle as well as lost 5% of my body fat. The strength gains were amazing as well, I broke my PRs on all of my major lifts.

The best thing about this cycle was that the RAD140 dosage was low so it barely suppressed me. Because of this, I didn’t need a PCT.

My cycle:

Week RAD140 Cardarine PCT
1-8 10mg a day 15mg a day /

RAD140 For Sale

Buying real, high-quality, pure Testolone is probably the best thing you can do to ensure a great cycle without side effects.

A lot of companies sell underdosed, bunk RAD140. This obviously makes your cycle dangerous. These bunk products are full of weird side effects and are very ineffective at getting the results that pure Testolone gives.

I have tested RAD140 and other SARMs from a lot of different companies. These companies give me the best results and no side effects as well as the lowest suppression. Their SARMs are definitely the purest on the market right now.


In conclusion, RAD 140 is a great SARM that has incredible benefits of lean muscle gain, fat loss as well as amazing strength gains. The best thing about this compound is that if you use a normal dosage (5-30mg a day) you won’t need a PCT and will recover naturally within a few weeks.

Remember to always buy real and high-quality SARMs and other compounds. This way you will avoid side effects and have great results. I recommend that you buy your RAD 140 and other SARMs from my recommended SARM companies, they have 100% real and quality products.


What Is RAD140?

RAD140 is a SARM (Selective Androgen Receptor Modulator). It promotes great muscle gains and fat loss as well as incredible strength gains.

How Does RAD140 Work?

RAD140 works similarly to the way that steroids work. The difference is that it is selective, it chooses the androgen receptor it binds to and therefore could cause a lot less side effects than steroids.

What Is The Proper RAD140 Dosage?

The proper dosage is 5-30mg a day. Research shows that a 5mg dosage is 80-90% as effective as a 30mg dosage.

What Is RAD140’S Half-Life?

Based on the studies done, we know that it has a half-life of 24 hours. This means that we should take a dosage every 24 hours for the best results.
