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 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 Science.bio – 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 you will require post cycle therapy afterward, especially when you run it for more extended periods.

Many also recommend adding in a 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 experience 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.

RAD140 Dosage Information

First, we want to start by saying that data shows us that Testolone is a powerful compound.

Those that have experimented with it told us that you should pay extra attention to the RAD-140 dosage protocol because you don’t want to take too much.

Research has shown that RAD140 is active at a dose of 0.01mg per kg of bodyweight. Take a look at the following image.

When we look at the above image, you could gain size by taking just a dose of 1mg per day.

The typical dosage for RAD-140 ranges from 5 to 20mg per day. Most users go for 10mg per day, as it is said to be the sweet spot.

Users advise to not exceed the dose of 20mg per day. As we mentioned, it’s a strong compound, and you won’t need more than that.

Keep in mind that the information regarding dosages is based upon anecdotal experiences.

Anecdotal experiences show us that a typical cycle will last between 6 to 8 weeks. They advise you to make sure not to run it for any longer than this.


The half-life of RAD140 is about 16 hours. Bodybuilders running a cycle are typically taking it once a day to maintain stable levels.

RAD140 And Suppression

Many of you reading this article are interested to know to what degree RAD140 causes suppression of natural testosterone levels.

For those that don’t know what this means, when you take compounds like SARMs, your natural testosterone levels get suppressed. Simply put, they’ll end up being a lot lower than they are naturally.

The suppression caused by this compound will be different for each person.

With that said, you will absolutely need some type of post cycle therapy supplement to help you recover from the suppression.

We advise using Rebirth PCT since it contains a wide variety of 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.

We’ve also wrote a guide on SR9009 (Stenabolic), make sure to give it a read.

Will RAD140 Cause Side Effects?

Based on the limited data and research we currently have available, we can conclude that RAD140 is not safe and could cause serious side effects.

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.

Anecdotal experiences tell us that it can cause suppression of hormones, aggression, and in some cases, nausea. These side effects seem to be dosage-dependent, but there is insufficient data available to back this up.

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

They also claim that you will absolutely need PCT and cycle supports products, preferably Rebirth PCT and Defend cycle support on hand. It’s better to be safe than sorry.

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.

RAD140 Alternative

We don’t approve the use or sale of RAD140 as it could have adverse effects. It is still being researched for its effects, meaning we don’t know what to expect from it.

So who knows what might happen down the line.

But, I know you’re interested in these compounds; otherwise, you wouldn’t be reading this writeup. I’ve also researched and studied them extensively.

We would highly recommend buying from a source that is known to provide high-quality, and 3rd party tested SARMs. We always use the following product: RAD-140 from Science.bio.

I’ve concluded that they aren’t entirely safe. I’m all about gaining size and strength, but we don’t know what further research will show us.

Instead of searching for places with RAD140 for sale (which is not allowed), 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. It doesn’t require any PCT or cycle support either which saves cash.
