Is RAD-140 Testolone the strongest SARM | HQSARMS

What is RAD-140?

RAD 140, also known as Testolone, was first developed in 2011, originally as a possible treatment for muscle wasting and breast cancer. Because research shows that this SARM has possible neuro-protective properties, there is ongoing research about the role it could possible play with Alzheimer’s disease.

The first human trial of RAD-140 has been conducted and finished in 2020.


RAD140 (Testolone) is a SARM (Selective Androgen Receptor Modulator). Just like other SARMS, it works by binding to the androgen receptors in selective tissue, specifically in skeletal muscles. As a result, it can produce many of the same benefits as androgenic anabolic steroids (AAS).

RAD140 works by selectively stimulating androgen receptors in the body. For instance, It targets receptors in the muscles and bones. But it has had little to no observed effect on the reproductive organs.

This compound stimulates muscle growth by promoting the development of muscle cells and proteins.

Because RAD-140 doesn’t affect the androgen receptors in organs like the prostate, it doesn’t have the same side effects that are associated with steroids. This doesn’t mean that it is free from unwanted side effects, but they are fairly limited when compared to those of AAS.

RAD-140 vs. LGD-4033

RAD-140 and LGD-4033 are both some of the strongest SARMs on the market. The main differences between both of the SARMS are:

  • Testolone is more effective in building mass in a short time, while LGD4033 is more effective in the longer term.
  • Testolone is stronger in terms of androgen activity while LGD-4033 has stronger anabolic effects.
  • RAD140 is more suppressive than LGD-4033.

Based on the available clinical research we know that Testolone is more potent than most other SARMs. It is without a doubt the strongest SARM around when it comes to building muscle mass and strength in a short amount of time. But because it has stronger androgenic activity, it also causes more suppression.

RAD 140 is one of the newer SARMs, and therefore it has been less extensively researched. In fact, the first human trial on RAD 140 has been conducted only recently.

But this hasn’t stopped it from gaining a massive amount of popularity among bodybuilders and athletes. The reason for this is simple: It is highly effective at building mass.

Rad 140 Chart


This particular SARM is associated with a wide range of effects and possible benefits, of which some have more anecdotal proof than others. The most common benefits associated with RAD140 are:

  • The potential to increase muscle mass on a caloric surplus
  • Limiting muscle wasting when used during a caloric deficit
  • Increasing bone density
  • Enhanced endurance and stamina


By targeting the androgen receptors in skeleton muscles, Testolone has the ability to increase muscle mass as well as strength without affecting the prostate or raising blood pressure. Since it does not aromatize or convert to DHT, it doesn’t come with the common negative side effects associated with androgenic anabolic steroids.


For the same reason that testolone can help to increase muscle mass it can also prevent muscle waste when on a caloric deficit.


As with all other SARMs, over time RAD-140 will improve the mineral density of your bones. You may even find that the compound prevents and aids recovery of previous bone injuries.


Another benefit of this SARM, is that it enhances performance. Most importantly, Testolone improves endurance and increases stamina.

SIDE EFFECTS of Testolone

RAD doesn’t have the same side effects that anabolic steroids do. More accurately, the severity of the side effects is less. But this does not mean that they are non-existing. In summary, the most common side effects are consistent with higher testosterone levels:

  • Increased aggression.
  • Increased hair growth in women.
  • Increase in libido.

RAD 140 AND Suppression

Of all the SARMs known, RAD140 causes the most amount of suppression in natural testosterone levels. This effect is still less when compared to most anabolic steroids, but it does mean that a PCT (Post Cycle Therapy) is highly recommended.

Although testosterone levels will usually recover in a short amount of time, many users prefer to take some form of PCT after cycling on testolone, just to be on the safe side.

Questions about TESTOLONE

How to make liquid RAD 140?

RAD140 is very soluble in DMSO, PEG-400 and to a lesser extent in Ethanol.

What is the correct dosage for RAD 140?

Testolone is active from a dosage as low as 1 mg. The most common dose lies between 5 mg and 20 mg a day, with 10 mg as the sweet spot.

What is the half-life of RAD 140?

The half-life of Testolone is long: Over 60 hours according to the first human trial that finished in 2020.
