Testolone(Rad 140) Review: Benefits, Usage & Side Effects

Updated on November 9, 2023

Testolone is an investigational SARM (Selective Androgen Receptor Modulator). It is regarded as a potential substitute for TRT (Testosterone Replacement Therapy). It is also known as RAD140.

Testolone helps you gain lean muscle mass and cut fat simultaneously. But it is not yet approved by the FDA (Foods and Drugs Administration). Thorough research is in progress.

Despite this, its popularity has only increased. Because it gives results quickly. Some users say it is better than Ligandrol. By the way, Ligandrol is stronger than pure testosterone!

What is RAD 140? Is it Legit?

Steroidal supplements are known to affect hormonal balance. The risk of heart attack and strokes is also higher. On the contrary, non-steroidal SARMs work selectively. This selective functioning is key. Their consumption leads to growth only in the muscles.

Testolone is the SARM available. It has given impressive results in a very short time. So, many people in the bodybuilding community use Testolone.

Testolone RAD 140 helps grow muscle in patients with muscle degenerative disorders and those undergoing chemotherapy. It is also used in the treatment of patients with breast cancer and prostate cancer.

It helps prevent and treat Alzheimer’s disease. Testolone also increases cognitive skills. It lifts the mood and makes you feel more confident than usual.

Lab Tests and Results

Only animals have been subjected to Testolone lab tests so far. It is yet to be tested on human subjects.

A study showed that Testolone increases lean muscle mass in nonhuman primates. But the increase in lean muscle mass was not considered significant.

In February 2011, researchers at the University of Southern California conducted a study on Testolone. According to this study, Testolone is safer than TRT for rats.


You can get SARMs in capsule and powder form. Some sellers also provide third-party lab tests with all their products.

Most sellers ship out your order in 1 to 3 business days. Depending on your location, international shipping takes between 7 to 10 days. Transit time to the US is about 10 days.

Make sure you return the product with all the accessories and original packing. If you have paid for the return shipment, you will be paid that amount within 14 days of repeal or return shipping.

How does Rad 140 work?

Let us understand how steroids work. Steroids are synthetic derivatives of testosterone. Consuming them has anabolic and androgenic effects.

Muscle growth is an example of anabolic effects. Signs of sexual development like enlargement of testes and facial hair growth are examples of natural androgenic effects.

Steroids stimulate the receptor molecules in the muscle cells. This results in the production of proteins.

Apart from enhancing protein synthesis, this also curbs protein degradation. As a result, users can handle more rigorous physical activities and recover faster from them.

Steroids are developed to increase the anabolic benefits with no androgenic effects. But all steroids come with androgenic effects as androgenic effects are essentially anabolic effects on sexual issues.

So, the steroids that are most potent in giving desirable anabolic results also have the strongest undesirable androgenic effects.

Although the function is the same, the chemical structures of Testolone and steroids are different. This is the reason why Testolone affects muscles, but not sexual tissues.

As Testolone does not affect sexual tissues, the user does not experience any androgenic effects. But this is true only when you consume Testolone in regulation.

Benefits of Testolone (RAD 140)

RAD 140 has numerous benefits, ranging from increasing lean muscle mass, helping to increase strength, promoting fat loss, enhancing stamina, and more.

Some proven benefits of disciplined consumption of Testolone are:

  • Increases lean muscle mass and strength: In a matter of weeks, you can see a significant increase in lean muscle mass. You also start feeling energetic.
  • Promotes fat loss: While gaining lean muscle, you can also lose fat simultaneously.
  • Increased stamina: You can endure physical activities for longer. You also recover quickly after a workout.
  • Enhances libido: You experience a higher sex drive.
  • Mental Clarity: Your focus will increase a few days into your Testolone cycles.
  • Can be safely stacked with other SARMs: Testolone can be stacked with Ligandrol and Nutrobal for bulking. Similarly, you can stack it with Ostarine and Cardarine for cutting.

Side effects of Unregulated Testolone (RAD 140) Consumption:

  • Lowered Testosterone levels: Consuming Testolone increases testosterone levels in the body. But when you overdo it, the body starts depending on this external source and stops producing testosterone naturally. This leads to hormonal imbalances. Hormonal imbalances cause side effects associated with steroidal supplements.
  • Muscle pain and swelling: Tendons attach the muscles to the bones. As the muscles are growing at a very high rate, some tendons and joints are unable to keep up with the increasing demands.
  • Restlessness: The body gets a lot of energy because of Testolone. If the user has too much energy, he/she is bound to get restless.
  • Headaches and Nausea: First-time users face this commonly. It usually goes away in a short time. In case it doesn’t, lower the dosage.
  • Acne and Blemishes: Taking doses higher than the body’s capacity causes acne and blemishes. They go away after the dosage is stopped.

RAD 140 Experience

I spoke to many people in the bodybuilding fraternity about Testolone. I have consulted doctors to understand how safe Testolone is. It took me weeks to do this detailed research. I went ahead with Testolone only after weighing the risks and rewards.

I started with a 5 mg a day dosage, which is a great RAD 140 dosage according to the clinical studies. And I increased it to 10 mg a week later. The first thing I noticed was the sudden increase in libido. It lasted for 3-4 weeks. Sometimes, I had mild headaches in the first few days of the cycle. Occasionally, some of my joints and tendons used to ache. But I did not experience any side effects after the second week.

Three weeks into my first ever Testolone cycle, I started gaining lean muscle. My shoulders and biceps had especially increased in volume. Veins were starting to become more visible.

In the past, I have gained muscle because of Ligandrol. Those gains were bigger in volume, but the muscles felt bloated. Testolone gave me smaller gains but solid muscles. Most of the gains from Ligandrol went away a few weeks after I discontinued the cycle. But my body retained most of the gains from Testolone even after I finished PCT.

The fat loss started in the fourth week. The stubborn fat around the midsection started to reduce. I had not experienced this with Ligandrol. Possibly because it causes water retention. I got shredded in just eight weeks. While Testolone is a big reason, I also did heavy workouts for 4 days a week. I even followed a calorie deficit diet throughout the cycle.

Both Ligandrol and Testolone increased my strength. But gains from Testolone are better aesthetically. Testolone assures you of amazing results if you honestly and consistently follow the guidelines. Just don’t cross the line.

How to use Testolone(RAD 140)?

Testolone is effective even in small amounts. So, it is crucial to follow a proper dosage. To avoid side effects, consume Testolone in cycles. And start with small doses. Better safe than sorry.

If you are a beginner, you can start with 5 mg Testolone daily for a week. You can then increase it to 10 mg a day. Because this is your first cycle, do this for at most 6 weeks.

If you have used Testolone before, start with 10 mg a day for a week. You may increase the dosage to 15 mg a day for the next seven weeks.

Experienced users who have had multiple cycles can start a daily intake of 20 mg per day. You can continue this for 10 weeks. If you notice any side effects in any cycle, discontinue immediately.

Testolone is not recommended for women. But if you still wish to give it a go, you can start at 5 mg per day. But women should never have more than 10 mg of Testolone in a day.

It is best you take the supplement daily in a single dose.

PCT is compulsory as Testolone inhibits the growth of natural testosterone. It is necessary to stay away from the awful side effects. You should do PCT for four to six weeks.

As part of PCT, you can take Nolvadex or Clomid. I recommend Nolvadex for users who have had Testolone for six to eight weeks. Take 20 mg a day for three weeks. Then reduce it to 10 mg.

As Clomid is stronger, I recommend it to those who have taken heavy doses of Testolone for more than eight weeks. Start with a daily dose of 50 mg for two to three weeks. Then lower it to 25 mg.

How to Stack Testolone?

Testolone is a strong SARM. Stacking it with more supplements can be risky. Consider stacking only if you have done several cycles of Testolone. And proceed only after consulting with doctors.

Depending on what you want to achieve by having the stack, here are some stacks including Testolone:


You have two stack options for bulking using Testolone:

Ligandrol LDD-4033 And Nutrobal MK-677

  • Dosage: 10 mg Testolone
  • 5 mg Ligandrol
  • 2-3 mg Nutrobal daily

You can expect to gain up to 10 lbs of lean muscle mass in eight weeks. You may also observe cutting to some extent. I recommend this alternative because it is milder.

Nutrobal MK-677 And S23

  • Dosage: 10 mg Testolone
  • 10 mg S23
  • 20 mg Nutrobal daily

This stack is quite strong. Use this for six to eight weeks only. Discontinue immediately if you experience any side effects.


Cardarine GW-501516 And Ostarine MK-2866

  • Dosage: 10 mg Testolone
  • 10 mg Cardarine
  • 20 mg of Ostarine daily

Cardarine plays a key role in burning fat. Ostarine lets you retain the gains, especially if you are following a calorie-deficit diet.

PCT is compulsory if you are stacking Testolone. You need to have 50 mg Clomid daily for eight weeks.

RAD 140: Frequently Asked Questions

Is Testolone a Steroid?

No, Testolone is a SARM, not a steroid. SARMs and steroids are not the same. This confusion is common because some people market SARMs as “legal steroids.”

How does Testolone make you Feel?

Testolone kicks in within the first two weeks. You start feeling very enthusiastic. You are always in a positive mood.

Within days of the start of your daily dosage, your sex drive spikes.  This goes away by the fourth or fifth week of the cycle.

Somewhere around the third and eighth week of the cycle, you start gaining lean muscle mass. You need to eat in a surplus for bulking. Veins also become more prominently visible.

The higher the dose, the more muscle mass you are likely to gain. Since you gain muscle at an unusually high rate, supporting structures like joints and tendons may ache initially.

This is why I recommend starting with a small dose and work your way up slowly and steadily. Starting with heavier doses is likely to cause acute pain and damage to tendons.         

Different bodies respond differently to Testolone. Some users may experience mild headaches. Some users may also experience kidney pain.

If you experience any such signs, reduce the dose. You can also stop the cycle and turn to PCT (Post Cycle Therapy) immediately.

Do you Lose the Gains after Stopping Testolone?

Most users experience muscle gain and some fat loss in one or two cycles of Testolone. With proper training and diet, you can retain most of the gains even after you are done with your cycle.

Is Testolone Safe?

Testolone is seen as a possible alternative to TRT. TRT is a procedure that people with low testosterone levels undergo.

Long-term benefits and risks of TRT are not known. TRT is linked with side effects like:

  • Acne
  • Breast development in men
  • A decrease in sperm count. It could also lead to infertility.
  • Higher risk of blood clots
  • Higher risk of heart issues like cardiac arrest and stroke
  • Shrinking of testicles

In comparison, Testolone has shown side effects only if the dosage is not carefully followed. Also, Testolone is found to be a lot safer than TRT for rats.

So, even though Testolone is not yet FDA-approved, it is safe when consumed in regulation.

What happens when you abuse Testolone?

Steroids immensely boost testosterone levels in the body. The body gets so used to this external source of testosterone that it stops producing natural testosterone.

This causes hormonal imbalances in the body. These imbalances are responsible for the nightmarish side effects associated with steroids.

SARMs also increase testosterone levels. But they do so gradually. Over time, using SARMs also suppresses the production of natural testosterone.

Testolone is the strongest SARM. Misusing Testolone can also stop the production of natural testosterone. So, all the side effects of steroids can be experienced by Testolone abusers, too.

This is why regulated dosage, following cycles, and PCT are very important.

What Is The Bioavailability Of Testolone?

Bioavailability refers to the fraction of the ingested drug that gets absorbed into the systemic circulation. A drug injected directly into the veins has 100% bioavailability.

In research conducted on primates, it was observed that 70% of the consumed Testolone got into the blood circulation system.

Does Testolone Cause Water Retention?

Multiple factors are responsible for maintaining the body’s water levels. The cardiovascular system hormonal balance, the kidneys, the liver, the urinary system all play pivotal roles.

Creatine pushes water into the muscles. Steroids cause hormonal imbalances. But Testolone does not have any such side effects when taken in moderation.

So, Testolone does not cause water retention. You only need to follow the dosage carefully.

Does Testolone Increase Blood Pressure?

Blood pressure and water retention are related. Water retention is a result of one or more factors including hormonal and chemical imbalances.

Since Testolone does not cause water retention, Testolone is not likely to increase blood pressure. With that said, some individuals do experience a marginal rise in blood pressure

Conclusion: Would I recommend it?

Even though Testolone is not legal yet, people from the bodybuilding community have been using it for years. Even I have been doing so for years. And it has given me great results in a short time.

Every person responds differently to different medications. There is nothing wrong if your body cannot cope with a certain amount of dosage. There is nothing to be ashamed of.

Start small. You can always increase the dosage as your body gets used to it. In case your body is unable to cope with a dosage, you can always discontinue or take it down a notch. The benefits of this powerful SARM are real. But with great power comes great responsibility.

So, consult with your doctor, follow a healthy diet, and take care of your body. Avoid overdosing and respect the process. The results will surely follow.
