What is RAD 140 (Testolone)?

RAD 140, otherwise known as Testolone, is classified as a SARM, which stands for “Selective Androgen Receptor Modulator.” This means it is comparable to steroids in its muscle-building effects, but has very few of the nasty side effects.

The way that SARMs work is they selectively target certain androgen receptors in your body, associated with muscle growth, while ignoring the other androgen receptors in your body which sometimes trigger nasty side effects.

SARMs such as RAD 140 have clinically proven benefits, such as:

– Faster Muscle Growth
– Rapid Fat Loss
– Enhanced Athletic Performance
– Increased Bone Density

Using SARMs, users can literally gain most of the benefits of steroids, with almost none of the side effects—and while SARMs certainly need more research to confirm these effects, much of the preliminary research is extremely promising.

RAD140, otherwise known as Testolone, is one of the most powerful SARMs in existence. In fact, according to the anabolic/androgenic ratio theory, RAD140 is literally 90% as effective as taking pure testosterone, and only has 1% of the side effects and aromatization.

How Does Testolone Work?

RAD-140, like other SARMs, are known for their ability to enhance muscle gain, strength, and speed along the process of fat loss. They do this by targeting certain receptors in your body.

These receptors are known as androgen receptors. When something binds to them, it tells your body to build muscle. This is why SARMs are so effective at helping users pack on pounds of lean muscle mass, in record time.

The key though, is that they only target the “good” androgen receptors, and they ignore the “bad.” When you take a steroid like Testosterone Enanthate or Trenbolone Acetate, they target all of your androgen receptors.

This is why steroids are known for giving such great results in the gym, but it’s also why they’re known for causing a plethora of side effects, such as:

1. Gynecomastia
2. Rapid Mood Swings
3. Terrible Acne
4. Liver Toxicity

Thankfully with SARMs, you will experience very few of these side effects. Let’s explore just how effective RAD 140 really is though, with some proven results.

RAD 140 Results

In a previous post on Testolone, Jon Anthony of Masculine Development explained that he gained 21 pounds of muscle, and lose 12 pounds of fat, in just 60 days on RAD-140.

In fact, these are the types of gains that most users can only experience on steroids, but thankfully, SARMs such as RAD 140 have almost none of the same side effects.

His RAD140 cycle consisted of taking 30mg/day, first thing in the morning, for 60 days total – and as you can see by the results images above, the progress was quite rapid.

Most of these results are not only from taking 30mg of RAD 140, but likely also from following a good workout routine, and adhering to a very healthy diet – SARMs without a proper workout routine and diet won’t give you those results, though – hard work is always required.

Most users think they’ll get the same results if they just take RAD-140, and while it’s true you may experience some good results, to get the most out of your SARMs cycle you want to combine it with a great diet, and rigorous workout routine.

In his report Jon said that he did not experience any side effects on RAD-140. This doesn’t mean that there aren’t any side effects that you should be aware of, however.

While on a SARMs cycle, always be sure to avoid drinking alcohol. SARMs are processed by your liver, so drinking alcohol can add an excessive amount of stress on your liver while on cycle.

Some potential side effects of Testolone include:

1. Gynecomastia
2. Back Acne
3. Testosterone Suppression

It’s important to note that these side effects will mostly appear in very high dosages, such as taking more than 30 milligrams of RAD 140 per day. Most science suggests that dosages under this amount are relatively safe.

In fact, according to studies, SARMs such as Testolone are very well tolerated, and users generally experience very few side effects while taking SARMs.

One study conducted by the Department of Chemistry at the University of Illinois, found that RAD 140 actually had some favorable effects on blood lipids, and was well tolerated:

“Clinical chemistry indicated the expected lowering of lipids (LDL, HDL, triglycerides).28 Despite the rather dramatic increases in body weight over such a short time, there was no elevation of liver enzyme transaminase levels in any animal at any dose >2 fold over its baseline value.29,30 Given the well-established relationship between oral androgen use and liver stress indicators, we were quite pleased that at a dose 10-fold greater than the fully effective dose we saw minimal liver enzyme elevations.31

This means that users can expect to take SARMs, and gain many of the benefits of steroids, with almost none of the side effects. So, if you’re intrigued, then read on.

Here are the best RAD 140 dosages: for 8 weeks, NO 12weeks

1. 10mg/day (Beginners)
2. 20mg/day (Intermediate)
3. 30mg/day (Advanced)

Depending on your experience with selective androgen receptor modulators, you may want to adjust your dosage accordingly. It’s recommended to take your dose first thing in the morning on an empty stomach, so that it immediately goes to work on your muscle receptors.

In addition to this, taking a post cycle therapy is highly recommended.


In conclusion, RAD 140 is a popular SARM which thousands of users across the world have taken to boost muscle growth, shred fat, and increase strength in the gym.

If you do decide to get on a cycle of RAD 140, always be sure to check with your doctor first – remember that this is not medical advice, just opinion and reporting on the facts.

After your cycle, be sure to run a post cycle therapy, to get your testosterone levels back up to normal – you can consider talking with your doctor if you’d like, as well, to make a plan.

In summary, Testolone is the most powerful SARM currently available on the market, but more research should be done to determine the long-term effects.
