RAD 140 Guide: Is Testolone The Strongest SARM in 2020?

RAD 140, otherwise known as Testolone, is a selective androgen receptor modulator (SARM) which has been growing in popularity lately.

Both research and anecdotal evidence show that RAD 140 is a highly anabolic SARM, which leads to rapid muscle gains in users.

There is an enormous amount of misinformation regarding RAD 140 (Testolone) out there, so in this article, we’d like to clear it all up.

While Testolone is an extremely powerful anabolic substance, and is currently legal for sale, there’s some facts you should know first.

What is RAD 140?

RAD 140, otherwise known as Testolone, is a potent SARM which is currently undergoing development by Radius Health, Inc.

While it was initially developed as a treatment for muscle-wasting in cancer patients, it didn’t take long before bodybuilders started using it.

After clinical research showed that RAD 140 leads to rapid muscle growth, many users began taking it for bodybuilding purposes. [R]

In fact, many users have been able to gain 10-15 pounds of muscle from a single 8-12 week RAD 140 (Testolone) cycle, hence the hype around it.

How Does RAD 140 Work?

sarms androgen receptors

RAD 140, similar to other SARMs such as Ostarine and Ligandrol, works by binding to your body’s androgen receptors, signalling them to grow.

Shortly after ingestion, studies show that RAD140 quickly begins binding to skeletal muscle androgen receptors, leading to rapid muscle growth.

This is what gives SARMs their potent anabolic, muscle building properties—they bind to your body’s androgen receptors, which signals your body to grow muscle and burn fat. [R]

Many people often compare SARMs to being “legal steroids,” and while SARMs are, in fact legal, there are some critical differences to understand.

RAD 140 vs. Steroids

While RAD 140 and other SARMs have very anabolic effects that are comparable to a low dose cycle of steroids, their mechanism of action is much different.

Steroids work by binding to all of your body’s androgen receptors—whether they’re in muscles you want to grow, like your biceps and triceps, or muscles you don’t want to grow, like your prostate muscles. [R]

SARMs, on the other hand, have a high affinity to skeletal muscles, meaning they avoid binding to the muscles you don’t want to grow, and target the muscles that you do want to grow.

This has led many bodybuilders to say that SARMs are like steroids without side effects, however this isn’t entirely true—we will cover this later on.

RAD 140 Benefits

Many people choose to take RAD 140 for the incredible muscle building effects it has, although technically it has not been approved for human use.

In terms of bulking SARMs, RAD 140 is one of the best. While it may not be as strong as Ligandrol, it gives your body more of a “cut and dry” look.

Here are some benefits of RAD 140:

  • Rapid Muscle Growth
  • Increased Strength
  • Higher Bone Density
  • Better Athletic Performance
  • Accelerated Fat Loss

Many users who take RAD 140 recreationally report gaining 10-15 pounds of muscle and losing fat at the same time, making RAD 140 a phenomenal SARM for both bulking and recomposition.

RAD 140 Results

The picture above was taken from Masculine Development, where Jon Anthony reported his RAD 140 results from a 60 day cycle.

The RAD 140 results pictured above were from taking a dosage of 30 mg of Testolone per day, for a full 60 days, or an 8 week cycle.

It’s important to note that 30 mg of RAD 140 is a relatively high dose, being on the upper end of what bodybuilders typically take for muscle growth.

As you can see, however, it’s quite possible to get steroid-like effects from a single cycle of Testolone, as it’s extremely anabolic when it comes to SARMs.

Dosage & Cycle Guidelines

While there is no medically established dosage of RAD 140, we can learn a lot by looking at anecdotal evidence and user cycle logs.

Here are the RAD 140 dosage guidelines:

  • Beginner: 10 mg per day
  • Intermediate: 20 mg per day
  • Advanced: 30 mg per day

While there is no established dose for Testolone, studies have found that even taking 0.1 mg/kg can lead to gains of more than 10% in 28 days. [R]

Most beginners choose to start off by taking 10 mg of RAD 140 per day for 8 weeks, which is equal to one full dropper of RAD 140 from Science Bio.

RAD 140 Bulking & Cutting Stacks

Due to its versatility as a SARM, Testolone (RAD 140) works well when combined with other SARMs, depending on your bodybuilding goals.

This is what’s called a “SARMs stack,” where users choose to take multiple SARMs at once, to get the most muscle-building and fat-shredding possible.

Sample Bulking StackSample Cutting Stack
RAD 140 – 20 mg per dayRAD 140 – 20 mg per day
Ligandrol – 10 mg per dayCardarine – 10 mg per day
YK11 – 10 mg per dayAndarine – 50 mg per day
Sample RAD 140 Bulking & Cutting Stacks

Doing a 12 week bulking stack of RAD 140, users can expect to gain 15-20 pounds in 2-3 months, and can expect to keep 85% or so of your gains.

Doing a 12 week cutting stack of RAD 140, on the other hand, might aid users in losing 10-15 pounds within 2-3 months, with all of it staying off (assuming that your diet and training stay the same).

RAD 140 Post Cycle Therapy (PCT)

SARMs do, in fact, suppress your natural testosterone production, so doing a post cycle therapy (or PCT for short) is highly recommended.

Here is a good post cycle therapy to run after you finish your RAD 140 bulking or cutting cycle, to get your testosterone levels back up:

Weeks After CycleNolvadexClomid
Weeks 1-240 mg per day50 mg per day
Weeks 3-420 mg per day25 mg per day
Sample PCT to Run After SARMs Cycle

In other words, after you finish your SARMs cycle, begin your PCT the day after your SARMs run out. Most SARMs will be out of your system within 2-3 days due to their short half lives, so you can run begin a SARMs PCT sooner than a steroids PCT.

To buy real, high quality SARMs PCT, we recommend going through Swiss Chems—both their Nolvadex and Clomid are HPLC tested for purity.

Potential Side Effects

While most users tolerate SARMs very well, it is important to note that there are still some potential side effects to be aware of while on cycle.

The effects of Testolone (RAD 140) are dose dependent, meaning that if you take a higher dosage, you will likely not only experience more muscle growth and fat loss, but also potentially worse side effects.

Here are the most common RAD 140 side effects:

  • Moderate Testosterone Suppression
  • Lowered “Good” Cholesterol (HDL)
  • Mild Levels of Liver Toxicity
  • Increased Aggression Levels

While many of these side effects can be mitigated by taking the proper supplements on cycle, it’s important to note that more research is needed to determine the longer term side effects of RAD 140.

Summary

In summary, Testolone, or RAD 140, is a potent selective androgen receptor modulator, which is known for its highly anabolic effects.

Many compare the muscle gains from RAD 140 to a low dose steroid cycle, making it a popular steroid alternative for bodybuilders.

If you’re looking for 99% pure, 3rd party verified Testolone (RAD 140), then we recommend you get it from a good vendor like Science Bio.

Each batch of their SARMs is tested for purity by an independent laboratory, and if you use the code “nanotech” you’ll save 10% off your purchase.
