Let’s breakdown Testolone (RAD-140).

We’ll review what a S.A.R.M. is, the benefits of Testolone, and how to use it to achieve your fitness goals.

1.  What is a S.A.R.M.?

When it comes to muscle building, you want to promote anabolic results; that is, you want to encourage your muscles to grow.

Short for Selective Androgen Receptor Modulator, a S.A.R.M. is a unique muscle building supplement in that it promotes all of the benefits associated with anabolic supplements without the horror story side effects.

Let’s discuss this further: What makes a S.A.R.M. so unique?

When you take a muscle building supplement such as an anabolic steroid, two types of characteristics are being promoted: anabolic and androgenic.

Anabolic focuses on an environment for muscle growth:

  • Increased levels of protein synthesis
  • Amplified insulin sensitivity
  • Enhancement of muscle glycogen
  • Rapid muscle recovery

Androgenic, on the other hand, promotes traits that are characteristic of a male:

  • Deep voice
  • Testosterone levels
  • Body hair
  • Bone structure and growth

Obviously, if you’re already a fully grown male or a woman, then you don’t want or need to have androgenic effects taking place in your body.  Androgenic effects are where the side effects come from that are so characteristic with anabolic steroids such as “‘roid rage” and “man boobs.”

I’ll talk more about this below.

A S.A.R.M. like Testolone is able to focus solely on the anabolic benefits and avoid androgenic effects, which ensures muscle growth and fat loss.

As we’ll jump more into below, a S.A.R.M. is able to promote these anabolic benefits by targeting specific androgen receptors in the body. The targeted androgen receptors are hand-picked to ensure that anabolic effects are triggered and androgenic effects are eliminated or, at the most, kept to a minimum.

2.  S.A.R.M. vs Prohormone

For some reason, S.A.R.M.s are still being lumped into the prohormone category.

Let’s get one thing straight: S.A.R.M.s are NOT prohormones. (Source)

In fact, the two couldn’t be any more different.  Most prohormones are packed with good marketing and not much else.

Using a S.A.R.M., on the other hand, is far more predictable in the results you can expect. A S.A.R.M. like Testolone will provide several key benefits without the side effects you’ll find with prohormones.

With that said, there are a few decent prohormones out there like Arimistane but if you want to save yourself the trouble, I’d recommend sticking with a S.A.R.M.

3.  Difference between a S.A.R.M. and a Steroid

We’ve already established the primary difference between the two but let’s dive a little deeper:

First, there’s the legal issue.

A S.A.R.M. is legal and anabolic steroids are not.

Although one thing they have in common is that they are both tested for if you’re entering any type of sports or bodybuilding circuit that requires a drug test.

The muscle gains that you receive with an anabolic steroid are, without question, superior to that of a S.A.R.M.

However, with that said, the side effects that come with anabolic steroids raise a question of whether it is worth it or not.

Premium anabolic steroids are incredibly expensive and come with the risk of organ damage and gyno-based symptoms such as low testosterone. (Source)

Trust me, I understand the need to pack on muscle mass but there comes a point when you have to weigh your options and find a balance between health and vanity.

A S.A.R.M. like Testolone primarily focuses on getting you shredded while promoting some increases in lean muscle tissue.

Best of all, you’re getting these benefits without the side effects that are on par with steroids.

Not a bad trade-off.

4.  What is Testolone (RAD-140)?

testolone reviews

Like many S.A.R.M.s, Testolone (RAD-140) started as a way to help increase natural levels of testosterone. Instead of getting a few injections per week to help increase testosterone, patients could take a S.A.R.M. like Testolone once a day as a part of a healthy diet and exercise program.

The appeal of S.A.R.M.s, especially RAD-140, is what we’ve been talking about this whole time: That is, Testolone can increase a positive hormone response without or with very limited androgenic side effects. Specifically, a S.A.R.M. like Testolone won’t trigger testosterone dependence nor will the body increase estrogen levels to match the boost in testosterone.

Despite a lack of clinical trial and research, the primarily user-reported benefits of Testolone quickly spread and turned it into one of the most popular S.A.R.M.s in the industry.

Yes, purchasing and using Testolone (RAD-140) is legal; however, it is tested for during sports and certain bodybuilding events. You don’t have to worry about it showing on a job interview drug test but if you’re trying to compete naturally in a bodybuilding show, for example, then Testolone will ensure your test comes back positive.

You can check out the full list on the World Anti-Doping Agency website.

6.  How Does Testolone (RAD-140) Work?

As a S.A.R.M., Testolone (RAD-140) targets specific androgenic receptors located in muscle tissue. (Source)

Unlike an anabolic steroid which turns on anabolic and androgenic effects, Testolone will only target those androgen receptors that promote an anabolic environment for muscle growth and fat loss.

7.  Potential Side Effects of Testolone (RAD-140)

You’ll be hard pressed to find any side effects associated with Testolone.

You can check forum after forum along with a variety of YouTube videos and still Testolone seems to be side-effect free.

With that said, research is still pending on Testolone (RAD-140) and so, I think it’s a good idea to play it safe and treat Testolone like an average S.A.R.M.

For example, one of the most common S.A.R.M.s, aside from Testolone, is (Ostarine MK-2866).

Ostarine has been reported on various forums as promoting mild side effects such as:

  • Potential low-level testosterone suppression
  • Mild acne (Source)
  • Mild (if any at all) hair loss (Source)

Again, none of these side effects have been shown to happen with Testolone but it’s better to prepare yourself for these symptoms and combat them as needed.

To combat all of these mild side effects, a simple post-cycle therapy supplement will suffice.

The idea is to natural keep testosterone levels high while minimizing DHT (Dihydrotestosterone), which has been linked to hair loss.

8.  What Does the Science Say about Testolone (RAD-140)?

I’m going to split this category up into two sections: First, I’ll talk about what is available in scientific literature.

Second, we’ll discuss the primary consensus about Testolone from users found across a variety of bodybuilding forums and websites.


Lean Muscle Gains (Without Fat)

Research into the practicality of Testolone as a fitness aid is still in its infant stages; however, what is out there right now looks very promising.

An article published in ACS Medicinal Chemistry Letters goes into great detail about RAD-140 and its mechanisms for promoting anabolic benefits.

While the tests were conducted on animals, the article concluded that RAD-140 was able to trigger an anabolic environment WITHOUT stimulating androgenic effects that may potentially harm internal organs.

In other words, all muscle and no androgenic side effects.

If this can be duplicated in human trials, RAD-140 will quickly become one of the best-selling supplements on the market.

May Protect Your Brain

Again, this particular study was performed on animals but the implications are huge.

RAD-140 was shown to prevent cell death while providing neuroprotective actions.

As the researchers conclude in their findings, if the results can be replicated in human trials, RAD-140 may be a powerful weapon against degenerative diseases such as Alzheimer’s.

User Reports:

Fat Loss & Cutting

  • The most cited user report about Testolone is how it is the perfect S.A.R.M. for cutting season.  Many users have described Testolone as an insane endurance booster that triggers intense working energy during exercise.  What’s more, several of these same users have submitted before and after pictures that show a clear difference in muscular definition.

Muscle Maintenance

  • If your goal is to put on serious muscle mass, then Testolone (RAD-140) may not be your first choice.  In fact, you may choose to stack it with a S.A.R.M. known to promote mass gains like Ostarine.  With that said, the majority of user reports have described Testolone as the ideal lean muscle protector especially when a special, calorie-limiting diet is involved.

9.  Benefits of Testolone (RAD-140)

  • May spare muscle tissue from catabolism
  • May combat age-related muscle wasting
  • May support hormonal balance
  • May promote lean muscle mass gains
  • May dramatically increase endurance
  • May boost recovery
  • Ideal for stacking

10.  How to Use Testolone (RAD-140)

The standard dosage for Testolone is 10 mg per day. It has a half-life of 12 to 18 hours so there’s no need to take two servings per day. Some supplement brands may be as high as 15 mg. I’d advise you start with 10, or even a lower dose, and work your way up over the course of 2 or 3 weeks.

Here’s a recommended cycle chart but be sure to check the label of the product as well. Dosages may vary from brand to brand.

Week 1: 5 mg

Week 2: 5 mg

Week 3: 10 mg

Week 4: 10 mg

Week 5: 10 mg

Week 6: 15 mg

Week 7: 15 mg

Week 8: 15 mg

11.  Stacking Method with Testolone (RAD-140)

Since Testolone (RAD-140) promotes high level endurance, lean muscle mass protection, and encourages fat loss, it is an ideal S.A.R.M. to be stacked with other compounds that trigger more mass, power, or strength gains such as:

Here is a recommended stacked cycle chart when you stack with Ostarine:

Week 1:

  • Testolone: 5 mg
  • Ostarine: 10 mg

Week 2:

  • Testolone: 5 mg
  • Ostarine: 15 mg

Week 3:

  • Testolone: 10 mg
  • Ostarine: 20 mg

Week 4:

  • Testolone: 10 mg
  • Ostarine: 25 mg

Week 5:

  • Testolone: 10 mg
  • Ostarine: 30 mg

Week 6:

  • Testolone: 15 mg
  • Ostarine: 35 mg

Week 7:

  • Testolone: 15 mg
  • Ostarine: 35 mg

Week 8:

  • Testolone: 15 mg
  • Ostarine: 35 mg

12.  Popular Brands of Testolone (RAD-140)

Since Testolone is still in the early stages of fitness-related research, genuine Testolone (RAD-140) may be hard to find. Here are the brands that users have reported to be real, high quality, and effective:

13.  Conclusion

When you want incredible definition but your diet and exercise program are only taking you so far, Testolone (RAD-140) may help give you that extra push.

Hailed as an incredible cutting S.A.R.M., Testolone is a fan favorite due to its muscle protecting and fat loss benefits.

Best of all, there is no risk of side effects that are common with other muscle builders such as prohormones and anabolic steroids.

While I’m excited by the reported benefits of Testolone, I would encourage you to take this S.A.R.M. with some healthy skepticism.

RAD-140 has very few scientific studies behind it.

The only thing that really bothers me about it is that there are claims that it is “side effect free” but that is 100% impossible and it drives me crazy when I hear such nonsense about a product, but in any case, this one actually just so happens to be a good supplement.

However, it has countless positive user reviews, which is a sign of serious potential, especially once more studies are published to back up the user reviews.
