RAD140 (Testolone)


Intro and history

Testolone (RAD140) is a selective androgen receptor modulator (SARM) that is under development by the company Radius Health (stock symbol RDUS). It has shown promise for increases in lean muscle mass and the prevention of muscle wasting.  The ultimate goal is for it to be a replacement therapy alternative to Testosterone, with lower side effects.

Testolone is fairly new, as it has been only seriously researched for the past decade.  The FDA (Food and Drug Administration) has accepted its new drug application, and human trials (NCT03088527) started in recent years.  Also, its popularity has made it very well known in the fitness community as one of the most powerful SARMs (selective androgen receptor modulators) on the market.

How it works

RAD140 and Testosterone both target the androgen receptor.  The difference is that Testosterone will also affect more than just organs, bone, and the central nervous system.  Testosterone will also cause testicle shrinkage because it affects the reproductive system.  The idea behind Testolone is that it bypasses these problems, because it is specific in its androgen receptor binding, going after just muscle and bone cells.  Instead of messing with organs like the liver or affecting sexual tissues.   So in simple English, Testolone (RAD140) does what Testosterone does, without the nasty side effects.

What Testosterone does inside you

Testosterone does some bad things inside the body for both sexes that Testolone (RAD-140) will NOT do.  They are:

  • Enlarge the prostate, and increase the chance of prostate cancer
  • Cause testicles to shrink
  • Shut down the pituitary glands, sometimes permanently
  • Head hair loss
  • Water retention
  • Heart strain
  • Gynecomastia
  • Acne and other skin issues
  • Aggression

Females have also had problems with an enlarged clitoris, deepening voice, body hair, and other male characteristics which are sometimes not reversible.

Once again, RAD-140 will do none of these things.

The Benefits of Testolone & User Reviews

Okay so we know what RAD-140 doesn’t do, but what can it do for me?

Increases lean muscle mass:

Initial studies on animals showed that using RAD-140 for 4 weeks increased lean muscle mass by up to 10% without side effects.  Human athletes have reported nice gains.  Here are some user reviews:

hardbodySR:  “I am a meathead and I always thought SARM’s were bullshit, but all my steroid use has done a number on my heart health.  I wanted to try the most powerful SARM so I bought 8 weeks of Testolone (RAD140).  I am already a big dude, 6’2 235 at 12% body fat. I have been lifting for 20 years so I just needed something to give me some extra lean mass.  After 8 weeks, I gained 8 pounds and dropped 1% body fat, without side effects.  Not bad, and now I am even bigger and my heart health actually improved.  I think I will stick with this instead of steroids for a while.”

pump1it writes: “I never used steroids, I’m just a little dork who always got picked on in school.  Tried Testolone (RAD140) as my first PED ever.  Went from 155 pounds to 166 in 12 weeks, set new strength records, never thought a little guy like me with shitty genetics could ever bench 250 without lots of steroids.”

batgirl says: “I am a female gym rat and I’m so happy I tried Testolone (RAD140).  My girlfriends used steroids and their clits got messed up and they got facial hair which is NASTY! I got the same results as them without the sides.”

Helps overall athletic performance:

Lack of energy seems to be a real problem today in our high paced society.  Testolone (RAD140) can help change that because it will boost lean muscle while also burning fat, improve speed, and raise endurance.  It is NOT a stimulant, so you will get sustained energy in the gym and feel great.

j260 says: “Don’t laugh at my post, but I am a Crossfit guy whose goals are endurance and getting stronger.  I wanted to try Testolone (RAD140) because guys at my gym talked highly of it.  After just 4 weeks I noticed greater recovery, stamina, and I wasn’t getting out of breath as easily as before.  This stuff is good!”

Fat loss:

Users have said they lost body fat on Testolone (RAD140) and this is due to an increase in metabolism.  When you increase lean muscle mass, you also will have an easier time losing body fat.  This is especially evident when you use it as part of a cutting stack as shown below.

How to Use RAD140


Testolone (RAD140) can be used from 5mgs per day up to 30mgs per day.  The average dose is 10mgs a day.

Stacking with steroids

RAD-140 is a very good idea during an anabolic steroid cycle because it will boost results, without increasing side effects.   A perfect way to take full advantage would be to use Testolone (RAD140) as your ‘Testosterone base’ along with 1 or 2 steroids of your choice.  This will give you all the benefits of Testosterone, without the androgenic or estrogenic risks.  A simple stack is Testolone(RAD140) 10mgs + Primobolan 500mgs per week for cutting, or Testolone (RAD140) 10mgs + Deca Durabolin at 400mgs per week for bulking.

Stacking with SARMs (selective androgen receptor modulators)

Testolone (RAD140) stacks well with any SARM (selective androgen receptor modulator) stack.  My favorite stacks are:

  1. Cutting:  Use 10mgs per day Testolone (RAD 140) + 20mgs a day Cardarine (GW501516).
  2. Endurance:  Use 10mgs per day Testolone (RAD 140) + 5-20mgs pre exercise of SR9009 (Stenabolic)
  3. Bulking:  10-30mgs a day Testolone (RAD 140) + 10mgs a day LGD4033 (Ligandrol)
  4. Overall Health:  10mgs a day Testolone (RAD 140) + 25mgs a day Ostarine Ostabolic (MK2866)
  5. Appetite increase:  10-20mgs a day Testolone (RAD 140) + 25mgs a day Nutrobal Ibutamoren (MK677)
  6. Recomping: Use 10mgs per day Testolone (RAD 140) + 20mgs a day Cardarine (GW501516) + 50mgs per day S4 (andarine).

Side effects

As mentioned, RAD-140 does not have the number of side effects as Testosterone or anabolic steroids.  However, you will have some slight suppression when using it so a PCT (post cycle therapy) is needed.  I recommend a mini-PCT with 8 weeks of Hcgenerate ES.

Where to Buy

Testolone (RAD140) is hard to find due to the financial crackdown on research chemicals in the United States over the past 2 years.  Due to this, many companies have simply closed their doors or moved overseas.  Luckily Sarms1.com and eSARMs still sell good quality products at an affordable price.
