According to studies, SARMs like RAD-140 show promise as wound-healing agents, as a treatment for osteoporosis and anemia, as a treatment for muscle-wasting associated with certain cancers, and even as a contraceptive for men.1

RAD 140 Testolone was first developed as a Testosterone Replacement Therapy (TRT) alternative.

TRT, also known as Androgen Replacement Therapy (ART) or Hormone Replacement Therapy (HRT), is used in the treatment of low testosterone (T) levels occurring with age or because of certain medical conditions, such as hypogonadism.

Studies show that, compared to other SARMs, Testolone is among the strongest on the market.2

Clinical data shows strong evidence that the potency of RAD 140 Testolone may be significantly greater than other SARMs such as LGD-4033 Ligandrol and MK-2866 Ostarine, particularly when it comes to building muscle mass and overall strength.3

As a result of this potency, the characteristics of Testolone are similar to conventional anabolic steroids.

However, the side effects are nothing in comparison.

A complete list of the benefits of taking RAD 140 Testolone is as follows:

      • Increased Muscle Growth
      • Bone Density Improvement
      • Improved Fat Reduction and Weight Loss
      • Increased Testosterone Levels
      • Energy and Power Booster
      • Improved Brain Function

More Detailed RAD 140 Testolone Benefits

The next section of this article will examine, in detail, the reported benefits of RAD 140 Testolone.

Builds Muscles

It specifically targets androgen receptors present in the bones and muscle tissue, thus increasing muscle size, muscle strength, and bone density.

Promotes Fat Loss

RAD 140 Testolone is a helpful fat cutter, melting down stored body fat, thus promoting weight loss in users.

Boosts Testosterone Levels

By increasing testosterone levels in the body, it has a euphoric effect of excitement and positivity and enhances sexual experiences.

It boosts energy levels, motivating and triggering enhanced performance with faster recovery.

RAD 140 Increases Brain Function

Amyloid-beta is a common protein associated with memory loss and other declines in brain function. It is an amyloid-beta blocker.

It can protect brain cells and enhance memory and learning by encouraging new brain cell growth.

Studies suggest that Testolone may help fight Alzheimer’s disease.4

Dosage and Cycle Instructions

As mentioned previously, RAD 140 Testolone is one of the most potent SARMs on the market.

Even the smallest dose of RAD 140 will affect the body.

Therefore, users should pay careful attention to dosage protocols to achieve the best results and avoid adverse effects.

Although there is a lack of medically established dose requirements for RAD 140, anecdotal evidence from user logs exists.

According to that anecdotal evidence, typical doses will range between 5mg and 20mg per day, with the average amount being around 10mg daily.

Advanced users have reported safely taking 30mg per day.

A typical RAD 140 Testolone cycle lasts from six weeks to eight weeks, and it is advised not to exceed an eight-week cycle.

Anecdotal RAD 140 Testolone dosage guidelines are as follows:

      • Beginners: 10mg a day
      • Intermediates: 20mg a day
      • Advanced: 30mg a day

Studies suggest that taking 0.1 mg of RAD 140 Testolone per kg of body weight can result in muscle gains of approximately 10% over 28 days.5

What the Research Says About RAD 140 Testolone

There is no doubt that RAD 140 Testolone can boost Testosterone levels in users and positively affect one’s overall performance and body composition.

Significant research shows an increase in neuroprotection from RAD 140, which is why it has a promising future as a treatment for Alzheimer’s disease.3

Unfortunately, when compared to other SARMs, not enough research data is available to truly understand all of the benefits that RAD 140 Testolone possesses.

RAD 140 Testolone Reviews

“The strength gains I experienced from this compound was unreal. All lifts jumped up significantly and I was hitting PRs every week.”
– Aesthetic_god0 in r/sarmssourcetalk

“Just got done with my rad cycle. Went from 145 to 162 in 3 months. All my primary lifts went up 50+ lbs. Didn’t need to pct thankfully as I didn’t have any noticeable sides other than some discharge from my penis.”
– GlobalMathmatician0 in r/sarmsourcetalk

“I’m on the end of my 6 week cycle of rad140, at 7.5mg a day. I can’t see any side effects. After 30 days, I had gained 5 lbs of skeletal muscle and dropped bf from 11,5% to 9,5%. Been working out for 11 years and these are the best gains I made so far. Always been natural and found that it was really hard to gain anything in the last years. So I’m satisfied with these gains! Currently at 185 lbs, for 5’10”.
– Alex__86 in r/sarmssourcetalk

“In short, I’ve made absolutely insane progress on just 7.5mg. I miiight bump up to 10mg towards the end of the cycle but I don’t even feel it’s necessary. I am curious how much more it would help though. I am blown away already, especially by the bench progress.”
– dingleberry51 in r/sarmssourcetalk

“I’m taking 90-100mg trt/week and 20mg ostarine daily. I’m only on the 2nd week, so far I’ve noticed increased recovery, and I can train harder in the gym. I’m not using it to bodybuild, I train boxing and muay thai. I do plan on using rad 140 paired with 5mg ostarine for joint health in a future cycle tho as I have heard others using it in mma.”
– DoDoMachine69 in r/sarmssourcetalk

“So I finished my first cycle 10 weeks Rad 10 then 15 then finish with 20mg a day. I never felt suppressed or really any different since I stopped and really the last 2 weeks of it I felt like I needed more but didn’t add more. But anyways I’ve been on pct for a week 20mg nolvadex daily I plan on doing 4 weeks 20/10/5/5 but I don’t really know if I need all that.”
– CapnBigNuts in r/sarmssourcetalk

“Overall thoughts: I’m happy with the results. I should’ve increased my calorie intake as I think I got too lean. Had veins running through my abs. I think getting this lean caused me to leave some gains on the table. Next cycle I will make sure to eat an additional ~200 calories.”

RAD 140 (Testolone) Side Effects

Most users report tolerating the compound quite well.

However, the potential for side effects while on a cycle of RAD 140 still exists.

Most RAD 140 side effects depend on the dosage.

While higher doses of RAD 140 Testolone may result in more rapid fat loss and increased muscle growth, but can also make the side effects significantly worse.

The most common side effects of using RAD 140 are as follows:

      • Testosterone Suppression
      • Lowered HDL Levels (HLD is “Good” Cholesterol)
      • Mild Liver Toxicity
      • Aggression
      • Hair Loss Acceleration

You can counteract most side effects of RAD 140 Testolone by adding other supplements to your cycle.

Stacking RAD 140 (Testolone) With Other SARMS

Because RAD 140 Testolone is such a versatile SARM, it works pretty well when combined with other SARMs.

When a user takes multiple SARMs together in a cycle, the process is known as “stacking.”

Depending on your goals, stacking helps you get the most fat-shredding and muscle-building results possible.

Most users will stack RAD 140 with either GW-501516 Cardarine or MK 677 Ibutamoren.

Stacking RAD 140 Testolone and GW-501516 Cardarine

stacking testolone rad-140 and cardarine gw-501516 is great for muscle gain and bulking

When you stack RAD 140 Testolone with GW-501516 Cardarine, you can expect the following results:

      • increased strength gain
      • increased muscle growth
      • rapid recovery time
      • incredible protein synthesis

A typical RAD 140 and GW-501516 Cardarine stack should look like this:

      • 25mg of RAD 140 Testolone a day combined with 25mg of GW-501516 Cardarine.

Doing this cutting stack in a 12-week cycle can help you lose roughly 10-15lbs within two to three months. If you maintain your training and diet, you should keep the weight off.

We strongly recommend the Sports Technology Labs brand for this particular stack, here’s a link to check it out:

Stacking RAD 140, LGD 4033, & YK-11 

mk-677 rad-140 and yk-11 is a perfect all around stack

RAD 140 Testolone has many steroid-like properties, and it behaves in much the same way as testosterone.

Because testosterone and HGH are anabolic, combining it with LGD 4033 Ligandrol and YK-11 Myostine is excellent for improving body composition.

Most users will take these compounds together for fat loss, anti-aging, and muscle-building.

The 3 are best combined in eight to ten-week cycles, like this:

      • 30mg of RAD 140 Testolone, 15mg of Ligandrol, and 10mg of YK-11 per day

Following an eight- or ten-week cycle, it is recommended that you take a four-week break before starting a new cycle.

A Post-cycle therapy (PCT) will not be required for cycles less than 12 weeks.   

We strongly recommend you pick up RAD-140, LGD-4033, and YK-11 from Sports Technology Labs.
