RAD 140: What You Need to Know

For recreational and competitive bodybuilders and other fitness enthusiasts, enhancing both performance and physique results is a common goal.

For many of these athletes, selective androgen receptor modulators, or SARMs, are helpful. SARMs offer an excellent and relatively safe way to assist those in physique and strength sports. SARMs have gained in popularity over the past decade. This is because of their ability to provide similar results to anabolic steroids without any of the serious side effects that steroids can cause.

RAD 140, also called Testolone, is one of the newest available SARMs. RAD 140 has been shown to increase endurance as well as speed and power. It also supports enhanced muscle growth and recovery.

SARMS: a Primer

Before delving into the specifics of RAD 140 and how it works, it’s necessary to understand how SARMs work. These agents are essentially an alternative to anabolic steroids. They offer the potential for significant muscle growth without many of the side effects that come along with anabolic steroids.

When a bodybuilder or other athlete takes anabolic steroids, the steroid compound acts largely like testosterone in the body. In men, this suppresses natural testosterone production. Excess androgens can be converted via the enzyme aromatase to estrogen. In men, these effects can lead to side effects like gynecomastia, testicular shrinkage, and male pattern baldness, among other effects. In women, they can lead to clitoral enlargement, a deepening of the voice, and even facial structure changes. In both sexes, these effects are largely permanent.

Understandably, many people who want some sort of chemical enhancement without going the steroid route are eager to try a middle ground. This is where SARMs come in. Unlike anabolic steroids, which act androgenically on all tissues in the body, SARMs exclusively bind to androgen receptors in bone and muscle tissue. This means that users are able to almost entirely avoid the adverse effects that come with anabolic steroid use. Most SARMs are virtually free of side effects.

How Effective are They? Are They Safe?

Many people read about the physique benefits of SARMs and believe that they are a “magic” supplement. They believe that a user can simple run a SARM cycle and gain considerable mass. This is similar to the tendency of the non-bodybuilding public to believe that any couch potato who takes steroids will turn into Mr. or Ms. Olympia seemingly overnight. Neither of these assumptions are true. SARMs, like anabolic steroids, have a very real ability to amplify results. But in order for them to work well, a bodybuilder must already have effective diet and training programs. You can’t slack off on training, eat junk food, and then take a SARM and expect to look good.

how safe is rad 140Of course, as with any relatively new development, there are plenty of people who question the safety of SARM use. Many of the most popular SARMs have been developed in recent years. However, SARMs as a class have been in existence for decades. Recent medical reviews of SARM use in clinical settings have found them to be safe, especially when compared to anabolic steroids.

The “clinical settings” in which SARMs are currently being evaluated are mostly those dedicated to helping those with diseases that cause muscle wasting. Physicians have known for decades that anabolic steroids can restore muscle mass and strength. However, the detrimental effects of these compounds make them somewhat impractical for clinical use. SARMs were developed in order to help fix disease-induced muscle wasting. This is because they have the ability to promote muscle growth without causing detrimental side effects.

Are They Legal?

is rad 140 legalOne other important feature of SARMs is their legality. For many, the fact that anabolic steroids are illegal is enough to give them pause when they’re considering whether or not to purchase them. On the other hand, SARMs can be purchased legally and easily in research chemical form. It is not technically legal to consume chemicals intended only for research. However, the actual purchase is completely legal. This eliminates the need for the use of cryptocurrency or secretive transactions.

That said, if you’re purchasing any SARM from a research chemical company, it is extremely important to look into the company ahead of time. Sales of research chemicals are not tightly regulated. Therefore, less reputable companies may water down the contents of each bottle or even substitute cheaper substances. However, if you’re careful and the product you get is genuine, you can start moving toward excellent results.

Now, we’ve gone over the basics of what SARMs are and why they are being developed. We now can look more in-depth at one SARM in particular – RAD 140, also called testolone.

What is Rad 140?

Of the currently available SARMs, RAD 140 is the most recently developed. If you are new to the world of SARMs, you may have realized that many tend to have unusual names consisting of a series of letters and numbers. These research chemicals have not been approved for official use in the medical field. This is why they are still being identified by abbreviations of their respective developers’ names. RAD 140 is currently being developed by a company called Radius Health, which explains the “RAD” portion of the name. Many of these compounds also have unofficial names that sound similar to the names of steroids – for instance, just as RAD 140 is also known as testolone, LGD-4033 is known as ligandrol.

Non-steroidal SARMs have been around for decades (and steroidal SARMs even longer). This supplement was announced to the research world in 2010, making it extremely new compared to some of the considerably older SARMs. Because of its general newness, there are far fewer studies on it than have been done on older SARMs, like the popular ostarine. Ostarine and older SARMs have been tested somewhat extensively on humans. Most RAD 140 studies have been done on animals, but the results are still promising. Further animal research is likely to lead to clinical studies in humans, which in turn will provide the bodybuilding community with valuable information concerning dosage and other variables.

While much of the general research on SARMs focuses on their mechanism of action and on their effects as a whole, experienced SARM users have noted that different SARMs have slight benefits in certain areas. For instance, ostarine is generally known as being especially useful as a cutting and recomp drug. Ligandrol (also called LGD 4033) is well-suited to bulking.

There is less of a general consensus on RAD 140, simply because this is such a new supplement. But with a 90:1 anabolic to androgenic ratio, it has the potential to create muscle growth similar to testosterone. Some users have noted that RAD 140 seems to improve speed and endurance as well. This supplement shows potential as an all-around performance enhancer as well as the potential for building muscle.

How Does Rad 140 Work?

Rad 140 how does it workBecause it is part of the class of selective androgen receptor modulators, RAD 140 works similarly to most SARMs. Like other compounds in this class, RAD 140 interacts with androgen receptors, but it interacts almost exclusively with the receptors in muscle and bone. Research has confirmed that SARMs, including RAD 140, act in a tissue-selective way. However, the exact mechanism of that tissue specificity is not well understood. Current research suggests that when the SARM binds to androgen receptors, it changes the receptor shape, which in turn helps create the anabolic effects that SARMs are known for.

This general idea of how testolone and other SARMs work explains the name “selective androgen receptor modulator.” This class of compounds is selective (because it targets only the androgen receptors in muscle and bone), and it causes receptor modulation (because it appears to alter the shape of the androgen receptor once it’s bonded to it).

Of course, scientists don’t fully understand the mechanism of action of even the oldest currently-available SARMs. While RAD 140 is a compound of the same class, it works in the same general ways. However, because it is one of the newest SARM compounds available, testolone is not yet backed by a significant body of research.

What Are Its Uses in Bodybuilding?

Rad 140 bodybuildingAs noted above, while the clinical trials and uses of RAD 140 and other SARMs have been largely limited to use in the medical setting. These trials have primarily focused on repairing muscle loss and muscle wasting, as well as treating osteoporosis and preventing additional bone loss. And while most of the official research on these compounds has not focused on bodybuilding, testolone has nonetheless become popular with the bodybuilding community for its ability to increase muscle mass without generally causing noticeable side effects.

Naturally, the selective action on androgen receptors in the muscle tissue leads to an increase in muscle mass and an improved training response. Many bodybuilding enthusiasts have noted that one of the primary benefits of anabolic steroids is the fact that they allow users to train more frequently and for longer periods of time. You can’t increase your training intensity and volume as much with testolone as you can with an anabolic steroid. However, this feature of enhanced training capacity is similar for both types of compounds.

Effects on Muscle, Bone, Tendons, and Ligaments

Testolone, because of its influence on androgen receptors, can also increase a user’s response to training. This means that if you use an identical training and diet regimen without testolone and then use the same regimen with it, the testolone will amplify your results. All other things being equal, you’ll see more form your diet and training when you pair it with a well-thought-out cycle of this supplement.

Understandably, most recreational bodybuilders focus on the muscle-building potential of testolone when looking at how it can help them improve their physiques. However, like other compounds in this class, testolone can also improve the strength of tendons and ligaments. For anyone who strength trains, this is a valuable effect. As bodybuilders make gains in muscular size and strength, it is vital that the tendons and ligaments also gain strength. Anyone who has suffered a tendon or ligament injury knows that healing can be a lengthy process. It also can lead to permanent damage and can severely hinder training.

Testolone, like most other SARMs, also decreases bone resorption. This means that it slows the breakdown of bone, which may increase bone density over time. In fact, many of the clinical studies of SARMs have focused on their potential uses in treating osteoporosis. In bodybuilding, this offers the benefit of reducing fracture risk. Fractures are not necessarily a common bodybuilding injury. But as with ligament and tendon injuries, a fracture has the potential to set back training considerably. There are also benefits for endurance athletes. For those who do a significant amount of high-impact cardio, intelligent supplementation may reduce the risk of stress fractures from overuse.

Effects on Training and Performance

RAD 140 has several benefits in terms of boosting speed and power. At first glance, it may seem as though this doesn’t matter for bodybuilding. But an increase in energy and endurance can help support increased training intensity. This is helpful for those who are training on reduced calories during a cut. Testolone can help users maintain existing muscle mass while cutting as well. The combination of these effects makes it ideal for a bodybuilder in a cutting phase.

This supplement’s ability to support explosive power output also has potential for bodybuilders. It is generally well understood that high-intensity interval training, or HIIT, leads to the loss of more fat in less time when compared to steady-state cardio. HIIT training relies on bursts of power. It also may preserve existing muscle more effectively than steady-state training. Thus, testolone’s ability to support explosive power may improve the quality of HIIT training, leading to improved fat loss and better preservation of muscle.

Of course, explosive power is also vital to strength training itself. Whether you need to push past the sticking point on your bench press or are working to get that final rep on your last set of OHPs, having the reserve energy to use explosive power when you need it is invaluable when you want to train as hard as you possibly can.

While its effects have the potential to dramatically increase results, this supplement has virtually no side effects. This is part of what makes it so attractive to athletes. And, as we’ll see in the following section, testolone also has some surprising additional benefits.

What are the Benefits?

Rad 140 testoloneWhile the often-discussed benefits of testolone include increasing muscle mass, reducing fracture risk, and improving the strength of tendons and ligaments (and doing so with few to no side effects), this compound offers some surprising benefits. Thus far, testolone also appears to be one of the best SARMs for energy support, endurance, and explosive power. This means that it can be useful for endurance sports as well as for fat loss and cardio-intensive training.

One of these benefits for male users is the fact that post-cycle therapy, or PCT, is not generally needed. When a bodybuilder or other athlete uses anabolic steroids, the inundation of androgens suppresses natural testosterone. Post-cycle therapy works to reduce the estrogen in the body and restore natural testosterone production. However, purchasing aromatase inhibitors and/or selective estrogen receptor modulators (SERMs) for PCT is an additional expense and hassle that most users of SARMs can avoid. It is important to note that some users of testolone and other SARMs do opt to run PCT afterwards. This is not generally necessary, though.

Using testolone, unlike using anabolic steroids, does not cause enlargement of the prostate or dangerous effects on cardiac health. It does not cause testosterone suppression and also does not cause gynecomastia. This is because it is not converted to estrogen. This benefit is key for male bodybuilders, as once gynecomastia becomes severe, it necessitates surgical treatment. This surgery can cause downtime and can be expensive as well.

As noted above, testolone offers female bodybuilders several benefits. One is the fact that, while it supports muscle growth and is highly anabolic, it doesn’t cause acne, clitoral enlargement, facial hair growth, or deepening of the voice. Testolone’s protective effects on bone may be of special interest to women. This is because women are generally more pone to osteoporosis than men are.

Testolone manages to spare its users virtually all of the negative effects of anabolic steroids. But one of the most important effects it avoids is that of liver toxicity. Steroids have an attached methyl group, which is toxic to the liver. Testolone and other SARMs, on the other hand, are non-methylated, meaning they are not toxic to the liver at all. In a similar vein, testolone does not cause the cholesterol imbalances that steroids can cause.

Studies in rats have indicated that testolone may protect neural tissue against neurodegenerative diseases. This indicates that it may have the potential to be used as a preventative measure against Alzheimer’s and similar diseases. While this benefit is not directly connected to bodybuilding or performance in other sports, it nonetheless indicates that RAD 140 has the potential to protect general health.

Testolone has several health benefits, but it also has a few convenience benefits. For one, it is taken orally. Like most research chemicals, RAD 140 has a generally unpleasant taste. However, taking it orally eliminates the potential pain and hassle of injection. As noted above, it also can be purchased legally. While testolone and other SARMs may not give users the same results that a high dose of trenbolone or other highly anabolic steroid would, the results are generally somewhat comparable. The results from RAD 140 also are generally free of side effects. They may even offer protective effects against a variety of potentially damaging conditions.

What are the Dosages and Proper Use?

Many research chemical companies and SARM distributors offer dosage recommendations for RAD 140. But the truth is that this supplement is new enough that exact dosage guidelines do not exist. Generally speaking, though, most dosage recommendations run from 0.3mg to 30mg per day. Because users will generally experience better results at higher dosages, many users prefer doses in the range of 20mg-30mg daily. Other sellers recommend a lower starting dose of 10mg/day for men and 5mg/day for women.

As with any supplement or drug, it’s a good idea to start at a fairly low dose in order to better assess your tolerance for testolone. Then, you can gradually increase the dose if needed. Splitting doses are not necessary. This is because the half-life of RAD 140 appears to be between 12 and 18 hours.

Many SARM cycles are run for 12 weeks, but some users prefer eight-week cycles. For bodybuilders who haven’t used SARMs before or who would like extra guidance in setting up a cycle, it may be helpful to consult a coach or a knowledgeable person who has used RAD 140 before. However, it is possible to figure out your own dosing based on research and some trial and error.

As far as actually taking the supplement, this part of the process is fairly straightforward. Research chemicals are typically sold in dropper bottles, and because they don’t necessarily taste pleasant, many are tempted to mix them with juice. However, it is important to drop them directly into your mouth. This is because, when you mix testolone in a glass, it may stick to the sides. You can, however, chase it with juice or something similar.

What are the Side Effects?

Rad 140 side effectsAs noted earlier, RAD 140 does not appear to have any noticeable side effects. However, it is important to note that, while the initial absence of serious side effects is promising, there is still the potential that more side effects will be found later. For other SARMs, side effects are minimal if existent at all.

Where to buy Rad 140?

One of the more attractive benefits of RAD 140 is the fact that it can be purchased online, and purchased legally. There are a wealth of research chemical companies that manufacture testolone. But because these sellers are essentially unregulated, it is extremely important to do your research ahead of time. Less reputable manufacturers may dilute or otherwise underdose. This is why choosing a seller that has its product independently tested for dose verification is a good idea. This is a good way to help make sure you get what you’re paying for in terms of quality and dosage.

We have done the research for you and found Proven Peptides to be the most reputable and best place to purchase Rad 140.

While this supplement is legal to buy, not all sellers accept credit cards. Some only accept money orders or bitcoin. If you do not have multiple payment methods you are willing to use, it may be difficult to purchase.

Some overseas sellers also offer RAD 140. However, if you choose to purchase it from another country, you should be aware of the possibility of it being held in customs. Purchasing it is legal, but buyers occasionally note that their purchases have been confiscated. To be safe, it is often best to buy from your own country.

FAQ about RAD 140

FAQ Rad 140As the newest available SARM, RAD 140 has inspired a fair bit of buzz in the bodybuilding community. And because it is so new, many potential users have a wealth of questions about it they would like answered. Below is a list of short answers to common questions about this supplement.

Is it Legal?

Yes – you can purchase testolone legally from a number of research chemical companies. However, it is technically legal for research use only, meaning the supplement is not being sold for human consumption. (If you are a competitive athlete, be sure to consult the section on banned substances below.)

Although purchase is legal, customs officials are often suspicious of research chemical orders from abroad. Therefore, buying from a seller in your own country is generally preferable.

Is it Safe?

Thus far, RAD 140 has not appeared to cause side effects. It is a new supplement, and further research is needed to determine whether long-term side effects are possible. However, other, older SARMs have been subject to more intensive testing, and none appear to cause serious side effects. Regardless, since everyone responds to compounds slightly differently, it’s wise to start with a relatively small dose. You can always increase your dose after you have established that you do not react badly to RAD 140.

Is it Affordable?

Pricing of RAD 140 will vary depending on a variety of factors, include the total milligram amount purchased and the seller from whom you are purchasing it. Generally speaking, however, RAD 140 and other SARMs are affordable and considerably less expensive than anabolic steroids. For male users, the fact that PCT is not typically needed with RAD 140 means that the cost savings is amplified further.

Because this is a newer supplement, there may be a range of prices offered, If cost is a major concern, comparison shopping may be helpful. Some newer manufacturers also offer introductory deals for new customers.

Is it a Steroid?

No. There are plenty of misinformed people who believe that anything that encourages muscle growth is a steroid. However, RAD 140, as a SARM, is part of a completely different class of compounds.

How Do I Take It?

Even for older and more established SARMs, dosing guidelines will vary depending on what sites you read and which people you talk to. Dosing is usually once a day, and anywhere from 0.3mg to 30 mg. Because RAD 140 is a liquid, it is usually taken from a dropper. If the taste is unpleasant, chasing it with juice or something else sweet or flavored may be helpful.

How Do I Know It Comes From a Reputable Source?

This is where research becomes incredibly helpful. When buying any product, it is helpful to do your research in order to select the best product variation for you. But with a research chemical like testolone, researching your source is particularly important due to the lack of regulation of the industry. There are many reputable manufacturers, but it may take some time and patience to make sure you’re ordering from one of the good ones.

Is It Safe for Both Men and Women?

Yes – this is a supplement that can be taken by both sexes. In fact, along with other SARMs, it is becoming a popular choice for female bodybuilders because it tends to yield impressive anabolic results without also causing the masculinizing side effects of anabolic steroids.

What Sports Can It Be Used For?

SARMs like this one are most commonly used for bodybuilding since they support both increased muscle mass and fat loss. However, testolone in particular is well-suited to use by endurance athletes as well, so it may work as a general performance enhancer.

Is it a Banned Substance?

Most athletic associations and federation ban the use all performance-enhancing drugs and supplements, which includes SARMs. If you are concerned about whether your association or federation allows for use of this supplement, be sure to consult with your association directly. Most have a continuously updated comprehensive listing of banned substances.


In conclusion, testolone, while it is still a very new supplement, shows considerable promise for use in bodybuilders and other athletes. Few supplements offer the combination of muscle-building advantage and lack of side effects that SARMs do. But this supplement is unique among SARMs – with an anabolic:androgenic ratio of 90:1, this supplement offers anabolic potential close to that of testosterone without the potentially deleterious side effects of excess testosterone supplementation. It’s also legal to buy and requires no needles. Add in the potential health benefits, and you have an extraordinary supplement that can improve not only your physique, but your health as a whole. If you have any more questions concerning Rad 140, you can visit our community forums.
