RAD140: The Complete Guide

Be it a professional athlete, an aspiring bodybuilder, a fitness conscious person or any person in general, the word ‘steroids’ would not be a new term for anyone.

While steroids have multiple physical benefits that might give you an advantage in sports, they come with a handful of side-effects that can’t be overlooked.

While everyone wishes to extract the benefits of steroids, no one desires to come face to face with the various side effects they carry.

Enhancing your muscle mass is by no means an easy task. Regardless of how much time you spend sweating it out at the gym or maintaining your strict diet, your body has a limit, there’s only so much it can handle!

This is why people wish they had something to help them enhance their efforts better, an alternative to steroids with minimal side-effects. This is where RAD140 comes into the picture as your fitness saviour.

What is RAD140?

RAD140 is a SARMs supplement that allows you to achieve your personal fitness goals without having to worry about the endless limitations that are associated with steroids. It is also known as Testolone and is only taken orally.

As a SARM, it selectively interacts with androgen receptors throughout the body. Testolone has garnered quite some attention towards itself.

It is because of it selectively activates receptors in the tissues to promote muscle mass growth without influencing the user’s sex associated tissues. This often becomes the cause of androgenic side effects in both men and women while using steroids.

RAD140 has the same effect on your body that testosterone exhibits. The main difference lies in that fact that RAD140 delivers only a mild boost of hormones all the while interacting with the receptors in the same way a large dose of testosterone would have.

Thus, the positive effects are similar to testosterone but without the multiple side effects. This quality of Testolone makes it a generator of desired anabolic effects while avoiding the occurrence of estrogenic side-effects that are accompanied by steroid supplements.


Testolone is a fairly new SARM as it has only been under research for a little over a decade. Initially discovered in 2010, it is currently being developed by the pharmaceutical company Radius Health.

Though the studies are limited as of now, hundreds of users on forums have reported that this is a highly promising supplement for building muscle without having to deal with the side-effects of anabolic steroids.

RAD140 has been tested on various animals for its effects, and now researchers are currently investigating it as a potential aid to increase muscle mass, fight against breast cancer and protect brain cells. The results seem promising and in favour of the supplement.

How Does Rad140 Work?

Mirroring the working of many other SARMs supplements, the mode of action for RAD140 is selective on the body. The problem that accompanies the use of testosterone is that in order to activate AR (androgen receptor) signalling to increase muscle mass and bone development, it also affects the sex tissues and other parts of the body, causing negative effects on the bodily functions.

RAD140, being the nonsteroidal selective androgen receptor modulator it is, keeps the other receptors of the body unaltered and untriggered. Unlike the structure of steroidal compounds that easily convert to other hormones, Testolone is not converted into other hormones like estrogen owing to its unique structure, thus, ensuring that the supplement doesn’t work undesirably.

According to the pharmaceutical company, Radius, RAD140 functions in the following way:

“…The potent, orally bioavailable and nonsteroidal RAD140 is designed to make the hormonal receptors in the tissues of the body act as if they’re getting a good dose of testosterone, setting off the same effects of prohormones and anabolic steroids minus the unwanted side effects…”

How Long Does it Take to Start Working?

You will start to notice the effects of RAD140 kick in your body if you are taking the recommended cycle length of 6 to 8 weeks for beginners. Experienced users, on the other hand, might push the cycle further to 10 to 12 weeks as per their needs.

You can see the results in as little as 4 weeks into the process of taking RAD140.

Recommended RAD140 Dosages

Dosages for Men and Women

As the supplement is yet to be clinically investigated on humans, it doesn’t have a well-researched dose range yet. However, resources usually advise a dose of 10 to 30mg per day for men.

Though it is safe for women, it is highly recommended that females take lower doses than men, which starts at 5 mg per day as the lower limit and should not exceed over 10 mg per day.

RAD140 Dosage Guideline

Minimum Dose Per Day Maximum Dose Per Day Length of Cycle
Male Users 10 mg 30mg Recommended from 8 to 12 weeks
Female Users 5 mg 10mg

Dosage for Bulking

For bulking, it is advised to use around 20 to 30mg of RAD140 on a daily basis for a cycle length that lasts up to 12 weeks. It is important to take a break of at least 4 weeks once the cycle ends to let your hormones settle back to their normal level.

To safeguard your health, as a beginner, it is highly recommended to start off by taking 50% of the suggested dosage and then gradually increase the level if you feel it working on your body without any evident side-effects Doing this will also increase the quality of the results.

Dosage for Recomping

Though body recomposition is an ideal fitness routine for beginners with little to no experience in muscle mass and weight loss, it is also beneficial for experienced lifters.

Using RAD140 this way might get you results slower than regular cutting with steroids or SARMs, but this slow and steady process will do its trick on your body without causing it harm. For recomping 20 to 30mg per day is sufficient.

Dosage for Cutting

Cutting is a bodybuilding phase when you eat less and try to shed body fat to end up lean whilst maintaining muscle mass. The recommended intake of RAD140 for cutting is around 10 mg per day on a 12-week cycle.

While taking RAD140, your workout session should include exercises like low-rep lifting and circuit training, which will help you maximize your fat loss all the while protecting your new gained mass.

Muscle Building Effects of RAD140

Due to your lethargic routine, bad body shape or recent use of steroids, your workout sessions can feel like you have to drag yourself to exercise. With the intake of RAD140, you won’t only feel energized to perform better, but will also witness prominent enhancement in your muscle mass.

Muscle Hardening Effects

While the muscle gain with RAD140 would not be as prominent as with the use of anabolic steroids or other SARMs, it still has a hardening effect that provides you with great results.

Strength Gaining Effects

Along with increasing your muscle mass and hardening your muscles, RAD140 will also help to make you stronger within 2 weeks into your cycle. You will notice your workout sessions becoming much easier to handle than before, and would be able to carry out many intense workouts, bypassing your personal bests.

Recomping Effects

Though using RAD140 would provide you with slower results as compared to what regular cutting would bring to your weight loss from traditional cutting, Testolone still does its work on your body effectively, slowly and steadily.

Cutting Effects of RAD140

SARMs were originally researched and designed to prevent muscle atrophy, which makes them ideal for cutting. You will be able to get rid of the extra fat and build up your muscle mass even if you are on a low-calorie deficit regiment already.

Accompanied by workout sessions that include low-rep lifting with circuit training, you would be able to maximize your fat loss and also protect the gains that you have already acquired.

Benefits of RAD140

The reason why RAD140 is claiming a name for itself in the fitness community is due to the benefits it carries with minimal side-effects. This SARM supplement can avoid the occurrence of negative effects since it only targets selective receptors rather than affecting the whole body.

In addition to fitness-related benefits, RAD140 also plays a pivotal role in combating various medical conditions.

Combating Breast Cancer

Breast cancer is the second leading cause of mortality in cancer-related deaths, making it an issue that many women deal with. Researchers have found that around 75% of breast cancer tissues are hormone receptor-positive, including estrogen receptors and sometimes, androgen receptor.

RAD140 has been implicated in selectively targeting the cells that cause breast cancer. It can block the side-effects of estrogen on breast cancer tissue by reducing the production of ESR1, a protein that causes the growth of cancerous cells in the patients of breast cancer. (We are not saying that this SARM is a cure for this disease, its just shown some promise so far)

Protection of the Brain

Androgens can increase the growth of brain cells, enhance your memory, and decrease amyloid beta accumulation- a protein that is the cause for the development of Alzheimer’s disease. RAD140 effectively protects your brain against neurotoxins and establishes a better state of your brain.

It also promotes a better quality of sleep and can enhance the sexual performance of the user, though there are no studies to back these effects yet.

Enhances Muscle Mass

In the fitness community, bodybuilders and athletes have been attracted towards the benefits of RAD140 in order to gain great muscle mass. It offers a way to enhance your muscle growth without causing unwanted side-effects that traditional anabolic steroids cause.

Promotes Weight Loss

There have been a handful of observations where the users of RAD140 were able to lose weight with the intake of the supplement. Along with that, they observed their lean muscle mass was not affected.

It also enhances your muscle mass, subsequently losing extra weight. This helps you to work on two functions together without the need to take separate supplements for weight loss and enhancing muscle mass.

Helps in Bodybuilding

One of the most popular benefits of Testolone is related to fitness and bodybuilding. It promotes both muscle building and weight loss, and both elements are extremely important in every bodybuilders’ regime, making RAD140 a great option for all the fitness freaks out there.

Half-Life of RAD140

The half-life of any supplement translates to the duration of time required for half of the substance to be used up in the body.

RAD140’s half-life is up to 18 to 20 hours.

This means that you can take your dosage in two different ways:

  • Take the complete dose at one go before going to bed.
  • Divide the dose, half to be taken in the morning and the other half in the evening.

If you are an athlete with a dope test coming up, give it 3 to 4 weeks to clear from your system.

When to Take?

While RAD140 works wonders for all, there are specific situations in which this supplement can work better in your benefit.

  • Men with sensitivity to Gynecomastia
  • Individuals who are using steroids cycles and wish to bridge between their cycles to maintain gain
  • Women who wish to gain muscle without acquiring a masculine appearance
  • Bodybuilders and athletes who wish to improve their performance
  • Men with low testosterone levels

Is RAD140 Safe for Women to Use?

Medical professionals recommend a lower dosage of RAD140, which means that there is no risk of possible virilization, the biological process which results in male secondary characteristics in female users.

This aspect of RAD140 makes it perfectly safe to be used by women as well.

Though it is safer than many anabolic steroids that often causes masculine characteristics such as abnormal hair growth, breast reduction etc, in women, it is advised that women take a lower dosage of RAD140 than men. The recommended dose being 5mg to 10mg per day.

Even though it is a safe option to go for, like other SARMs, can result in side effects like:

  • Acne
  • Deepening of voice
  • Increased sex drive

These are just possible side-effects. Before taking a supplement completely into your fitness regime, it is important to study every aspect of it in accordance with your own health and fitness goals.

Cycle Length of RAD140

Ideally, all users of RAD140 should follow a strict cycle length to use this substance. People make use of a cycle where they consistently take it for about 8 to 12 weeks.

It is important to note that after this cycle is complete, you should stop using the supplement to allow the bodies hormones to settle back to their natural state.

A mild PCT is also advised to speed up this process. This process is known as Post Cycle Therapy, which is conducted to ensure the safety of your body and minimising the risks of any undesirable post cycle consequences.

Apart from the cycle of consumption, the post cycle therapy should be followed in a set manner as well. While the length of PCT may vary from person to person, it is directly linked with the duration of dosage period you follow.

If the user has been using the supplement for 8 weeks with the required consistency, then they should take a break from the drug for at least 8 weeks.

Thus, the number of weeks you were using Testolone should be the same as the number of weeks you should give your hormones the break to settle back to normal.

What Stacks Well With RAD140?

Though RAD140 works pretty strong alone, it may be a good idea to stack it with some supplements to extract enhanced results from your cycle.

A good way to gain maximum advantage from it would be to use Testolone as your testosterone base along with 1 or 2 steroids or other SARMs supplements. This will help you get the maximum benefits minus the estrogenic and androgenic risks.

Many users suggest that stacking RAD140 with MK677 or Ostarine, it might turn out to be a great combination. If you wish to seek benefits in cutting or endurance, Cardarine becomes an ideal stacking option.

Is PCT Needed After Using This?

Since RAD140 does not affect your hormone level to a great extent, it doesn’t call for a strict post cycle therapy to be followed. However, many users strongly suggest that to help your body and hormones get back to the state they should be levelled at, it is better to follow a post cycle therapy.

Side Effects of RAD140

One of the biggest charms about RAD140 is that it carries minimal side-effects as compared to other testosterone steroids. However, since it is in its early stages of development and research, any possible long term side-effects are not yet analysed completely.

Analysing the way SARM functions, RAD140 ought to have a lesser intensity of side-effects than testosterone, yet, it  has the potential to result in testosterone related side-effects which the user may face:

  • Insomnia and headaches, both of which can disappear if the doses are taken correctly.
  • Changes in sex drive
  • Mood swings due to possible hormonal shifts
  • Nausea and vomiting
  • Abnormalities in body hair growth in females
  • Pattern baldness or hair loss in males
  • Anxiety or depression
  • Breast growth or tenderness in men [1, 2]

Is it Legal?

RAD140 is legal and can be bought easily, but one should be careful while buying it online.  In a recent study, it was analysed that the 44 different SARM products that were being sold online contained only 52% SARMs in them.

In addition to all that, it was found that 39% of the products contained an unapproved drug, and 25% carried substances that were not listed on the label of the supplement.

Though it is legal to buy RAD140 for research purposes, it has still been banned in the field of professional sports, making its way to the prohibited list of the World Anti-Doping Agency.


As mentioned throughout the content, backed up with trustworthy medical sources, it is safe to say that RAD140 is one such supplement that comes with minimal side-effects, and the pros of the compound weighs way heavier than the cons, making it an ideal option for those who wish to witness desirable changes in their body.

To extract even greater benefits, it is recommended that one should use RAD140 along with other supplements, making the best of the opportunity.

While the research for this SARM is still underway and a lot is yet to be discovered, it has already positioned itself as a fitness supplement that you can put your faith in.

While gaining muscle that mirrors that of a bodybuilder might not be your cup of tea, everyone should work towards losing undesirable weight and get the ideal body that they always dreamed of, and RAD140 becomes an excellent instrument to help you acquire that.
