RAD140 Guide: How To Use Testolone, Benefits & Results Inside

RAD140 is a potent, selective androgen receptor modulator (SARM). Some of you might know this compound as Testolone.

SARMs such as this one have gotten so popular because they’re considered to be performance enhancers.

Many think that they are a better and safer alternative to anabolic steroids and prohormones. What most don’t know is that this compound can be just as dangerous.

Before we dive further into this article, it’s essential to know that RAD140 (Testolone) is still being researched thoroughly, and use is not approved.

Here’s one of the latest clinical studies.

Disclaimer: RAD140, also known as Testolone, is an unapproved and experimental drug. We do not condone the use of this compound and suggest staying away from it. Upon request, we are merely providing information available from clinical and anecdotal experiences.

RAD140 SARM Review


RAD140 was created by Radius health in the hopes of it being a safer alternative to Testosterone Replacement Therapy (TRT).

It’s also used for other muscle-wasting diseases because it might be able to help increase lean muscle growth.

Bodybuilders and athletes often use this compound to optimize performance by increasing size, but the drug is unapproved and could cause serious adverse side effects.

When we compare RAD140 to other SARMs, it’s really one of the strongest ones out there.

When looking at the clinical data available, it has shown to be more potent than other compounds such as LGD-4033 and MK-2866, especially in building mass and strength.

RAD140 Testolone Molecule Structure

We don’t recommend using RAD140 – however, if you are keen on buying RAD-140, we would recommend buying it from a trusted source. We had the best results with products from Chemyo- click here to buy RAD-140.

We’ve had similar results with a product called Ecdysterone, which doesn’t cause adverse side effects.

Bodybuilders that have told us about their experience with RAD140 said that they will require post-cycle therapy afterward, especially when they run it for more extended periods.

Many also recommend adding in cycle support because of potential adverse effects. It’s why we recommend steering clear from SARMs such as this one.

What To Expect From RAD140

We’ve spoken with bodybuilders who have tried this SARM and were willing to share their experiences with us. They mentioned that they found it to be highly effective for boosting muscle mass and strength. After just one week of using it, they noticed significant increases in muscle mass and strength.

That’s why they use it gets used for both bulking and cutting.

During a bulk, they claim it helps increase the amount of lean muscle tissue you have. For them, it is one of the best sarms for bulking.

When cutting, it can help them stay big and vascular. It’ll make sure you don’t lose any mass when in a caloric deficit.

Testolone benefits

Bodybuilders claim that this compound helps them:

  • Recover faster than naturally
  • Gaining muscle mass will become a lot easier
  • Your strength will increase rapidly
  • More muscle fullness and vascularity

But, keep in mind that Radius Health is still researching it. That means we don’t know everything about it yet. Once more research is publicly available, our content will be updated.

Therefore, we do not approve the use of this SARM or any other one of that matter.

Please keep in mind that our article’s claims are also made from anecdotal reports and experiences – clinical studies or data have not backed them up.

We’ve also taken an in-depth look at other compounds. Check out our article on the YK11 Sarm.

Testolone Benefits

One of the primary benefits of RAD140 is its ability to target androgen receptors in the muscles and bones selectively. This results in increased muscle mass and bone density without the negative side effects typically associated with testosterone therapy.

RAD140 also has a number of other benefits, including:

  • Reducing body fat – RAD140 has been shown to reduce body fat while preserving muscle mass. This makes it an ideal choice for those looking to lose weight without sacrificing muscle mass.
  • Improving sexual function – RAD140 has been shown to improve sexual function in both men and women. This makes it a good choice for those looking to improve their sex life.
  • Reducing inflammation – SARMs have been shown to reduce inflammation, which can be helpful for those struggling with conditions like arthritis or asthma or after an intense workout.
  • Reducing the risk of age-related diseases – RAD140 has been shown to reduce the risk of age-related diseases, such as Alzheimer’s disease and dementia.
  • Improving cognitive function – RAD140 has been shown to improve cognitive function, which can be helpful for those already struggling with conditions like Alzheimer’s disease and dementia.
  • Reducing the risk of cancer – RAD140 has been shown to reduce the risk of cancer, making it a good choice for those at risk for cancer.

Although the range of possible benefits is still being closely researched, many bodybuilders opt to take RAD140 for its body-specific benefits. Many athletes claim that this compound helps them:

  • Recover faster than normal, likely due to its ability to reduce inflammation
  • Gain muscle mass, as it closely mimics the effects of testosterone
  • Gain strength as muscle tissues grow denser and larger
  • Main muscular fullness and vascularity, even during a cutting phase

It’s essential to point out that Radius Health is still in the process of developing and researching RAD140. It’s impossible to say with 100% certainty what the exact range of its effects is. Once more research has been made public, we will update our content and let you know what we find.

For this reason, we don’t approve of or recommend the use of this or any other SARM. There simply isn’t enough data to back up the findings, and we still don’t know the long-term side effects of taking these compounds.

Please keep in mind that our article’s claims are also made from anecdotal reports and experiences. Not all of the data has been backed up by science.

RAD140 Dosage Information

Although we don’t recommend taking RAD140, if you’re willing to experiment with Testolone, it’s best to do so with as much knowledge as possible.

First, we wanted to point out that the current data suggests that Testolone is an incredibly powerful compound. Those who have experimented with it have told us that you’ll need to pay extra close attention to your dosages to avoid taking too much.

Taking too much Testolone can lead to some nasty side effects, which we’ll get into later in this review. Therefore, stick to the recommended clinical dosage of around 0.01 milligrams per kilogram of bodyweight. Scale-up from that dosage, being sure to take no more than 20 milligrams a day.

Even at a dosage as low as 1 milligram, studies have found that RAD140 can have powerful effects, so you could see gains without taking much of the compound at all.

For bodybuilders, though, many who have experimented with the SARM recommended taking between 5 and 20 milligrams every day. Most reported taking around 10 milligrams to hit their sweet spot.

Most importantly, though, even hardcore bodybuilders recommended sticking to a dosage below 20 milligrams a day. As we’ve mentioned already, it’s a potent compound that’s still undergoing research, and you won’t need much more than that amount to see results. Pushing past that dosage could even put you at risk of long-term health effects.

Additionally, keep in mind that the information we’ve presented here is based almost entirely on anecdotal experiences. These user reports have shown us that a typical cycle will last between 6 to 8 weeks, and most advised you to make sure not to run it for any longer than this.

As we gain more information from clinical trials, we will update our data and let you know how much RAD140 you can safely take from day to day.


The half-life of a drug is the amount of time it takes for the concentration of the drug in the blood to be reduced by half.

This is determined by the rate at which the drug is metabolized within the body. Half-life is important because it affects how long a drug remains in the body. It also affects how often a drug needs to be taken.

A drug with a short half-life needs to be taken more often than a drug with a long half-life. Half-life also affects the intensity of a drug’s effects. Drugs with a short half-life are eliminated more quickly and tend to have a more pronounced effect. Drugs with a longer half-life are eliminated more slowly and tend to have a more subtle effect.

When it comes to Testolone, the half-life of RAD140 is about 16 hours. This means that bodybuilders running a cycle should ideally take a dose of the compound once a day to maintain stable levels.

If you’re willing to experiment with the compound, we recommend taking it in the morning with your other supplements. This way, you can maintain a regular schedule.

RAD140 And Suppression

Many of you reading this article are probably curious to know whether taking RAD140 can cause the suppression of natural testosterone levels.

For those of you who are unfamiliar with what this means, when you take compounds like SARMs, they can suppress your natural testosterone levels, forcing them to drop a lot lower than they were before you started taking the supplement.

The reason why SARMs can cause testosterone suppression is that they bind to androgen receptors. Androgen receptors are responsible for the production of testosterone. When SARMs bind to androgen receptors, they block the production of testosterone and prevent your body from generating new hormones.

The suppression caused by this compound will be different for each person. Some of the most common symptoms of testosterone suppression include:

  • Loss of muscle mass
  • Increased body fat
  • Decreased libido
  • Erectile dysfunction
  • Decreased sperm count
  • Gynecomastia
  • Fatigue
  • Depression and mood swings

Of course, the severity of symptoms will vary from person to person, with some people experiencing only a handful of these symptoms while others may experience them all.

So, with that said, you will absolutely need some type of post-cycle therapy supplement to help you recover from the suppression. Post-cycle therapies (PCT) are treatments used to restore the body’s natural balance after taking anabolic compounds.

PCTs may include drugs such as clomiphene citrate (Clomid) and tamoxifen citrate (Nolvadex), which work by stimulating the body to produce more testosterone. Other PCTs may include human chorionic gonadotropin (HCG) or growth hormone (GH), which help to restore the body’s natural testosterone production.

We advise using Rebirth PCT since it contains a wide variety of natural ingredients that will focus on raising hormone levels back to normal. If you don’t focus on recovering from the hormone suppression, you can lose gains and end up feeling horrible.

Will RAD140 Cause Side Effects?

For those who want to know if RAD140 is safe, we don’t think that it is. The anecdotal reports show us that it can do some damage in terms of side effects.

Based on the limited data and research we’ve been able to review, we can conclude that RAD140 is not safe and could cause serious side effects. Unfortunately, there’s not much scientific information available on this compound, which is one of the main reasons why we are against SARMs such as this one.

That being said, though, anecdotal reports suggest that it can cause the suppression of hormones, leading to serious health issues, aggression, and in some cases, abdominal problems. These side effects seem to be dosage-dependent, but there is insufficient data available to back this up.

If it’s anything like other SARMS, though, we expect that RAD140 can cause:

  • Joint pain
  • Headaches
  • Nausea
  • Dizziness
  • Fatigue
  • Increased appetite
  • Heart palpitations
  • Liver damage

If you begin to experience any of these symptoms, stop taking your SARMS and speak to a doctor.

You will likely have to take a PCT, as well as cycle support products, such as Rebirth PCT and Defend cycle support, to protect your organs during the cycle. Read more in our SARMs PCT guide.

Alternatives To RAD140

SARMs aren’t safe and can cause side effects. Therefore, we advise checking out other alternatives.

There are still quite a few potent over-the-counter muscle-building supplements available. 

I’ve had insane results with Ecdysterone by Huge Supplements, a newly formulated muscle-builder.

With an 8-week cycle of Ecdysterone, I managed to gain 7lbs of lean mass. It contains a powerful ingredient called beta-ecdysterone.

It also doesn’t require any form of PCT, which is nice as well.

RAD140 is still under investigation, meaning anything could happen in the future, showing us it wasn’t safe. We recommend staying away from it.

SOurces With RAD140 For Sale

Again, we don’t approve of the use or sale of RAD140 as it could have adverse side effects. It’s still being researched and has not been approved for use in humans.

Therefore, we don’t know what to expect from it. However, we understand that, if you’re reading this, you’re likely curious about the compound and may be trying to purchase it from the Internet.

If you’re willing to experiment with research compounds, our best advice is to purchase high-quality products produced according to professional lab standards. After extensively researching and studying RAD140, we can recommend a vendor who we came to trust— Chemyo.

Chemyo deals in a wide variety of SARMs and follows stringent protocols to guarantee that its products are all of the highest quality. A sample from each batch is sent off for testing at a third-party laboratory, where the SARMs are analyzed for purity and concentration. You can find the results of each test on Chemyo’s official website and contact the lab directly for more information.

Thanks to these quality control measures, we feel confident saying that Chemyo is your best bet for purchasing Testolone. However, after concluding that the SARM isn’t entirely safe, we’re not sure that RAD140 is really your best bet for building stronger muscles without damaging your health.

RAD140 Alternative

Instead of searching for places with RAD140 for sale, go check out some potent alternatives such as Ecdysterone.

We’re already planning our second cycle with it since we’ve gained 7lbs with the first one with no sides. You can check out Ecdysterone on the official site, and it doesn’t require any PCT or cycle support either, which saves cash.
