If you’ve researched the SARM RAD-140, then you may be wondering: what is RAD-150 (TLB-150 Benzoate)?

RAD-150 is the latest compound gaining all the attention when it comes to research chemicals and the bodybuilding industry. With its predecessor RAD-140 taking the top spot when it comes to best-selling SARMs, everyone is wondering how RAD-150 compares and why its rapidly gaining the same level of popularity.

Selective androgen receptor modulators (SARMs) are tissue-selective research drugs similar to steroids. But unlike steroids, SARMs don’t cause systematic effects. That means they only bind to muscle tissue androgen receptors and leave the rest of your body alone.

The latest SARM to hit shelves in the UK is RAD-150, also known as TLB-150 Benzoate. This research chemical is an anabolic ester. That means it better mimics the role of natural testosterone in the body as compared to non-esterized SARMs.

If you’re curious about RAD-150’s potential benefits and what sets it apart from other SARMs, keep reading for everything you need to know.


You may know that SARMs such as RAD-150 are research chemicals. What you may not know is what that actually means.

Research chemicals are compounds scientists use in pre-clinical or clinical research. For example, scientists first discovered SARMs when they were researching chemicals for prostate cancer treatment.

The thing about research chemicals is that they were originally intended for laboratory settings and not for human consumption. When you purchase SARMs from Pumping Iron, you’re consenting to the legal use of these products.


Like all SARMs, RAD-150 binds to androgen receptors in skeletal muscle tissue. When these receptors get activated, they cause a host of downstream effects. These effects boost muscle hypertrophy, which is the same process that occurs during weight lifting.


A 2020 study of SARM research chemicals found that many products on the market aren’t what they say they are. The researchers found that some products studied:

  • Claimed to contain active ingredients but these ingredients weren’t present in the supplements
  • Included prohibited analytes that weren’t listed on the label
  • Lacked information about the product’s safety and toxicity
This is why you should always buy research chemicals from a reputable brand. To ensure your safety, only choose SARMs from brands you can trust, like Umbrella Labs


RAD-150 provides many of the same benefits as other SARMs. For example, this research chemical can encourage lean muscle growth and reduce body fat. RAD-150 may also speed up muscle regeneration after a workout.

That’s not all, though. Some users also report increased libido and improved sexual performance after using RAD-150.


So far, the most touted side effect of RAD-150 is insomnia. This makes sense considering this research chemical has a longer half-life. Skipping days between doses or taking smaller doses may help reduce or eliminate this side effect.


If you’re familiar with SARMs, you may be wondering: isn’t there a RAD-140 research chemical on the market already? RAD-140 or testolone first emerged as a safer form of Testosterone replacement therapy. It’s also a potential breast cancer tumor suppressor.

RAD-140 is the predecessor to RAD-150. They’re highly similar chemicals that look almost identical, giving them many benefits in common. For example, RAD-140 and RAD-150:

  • Enhance muscle gains
  • Boost fat loss
  • Improve strength
So, what’s the difference? As we’ve mentioned, RAD-150 is an anabolic ester. RAD-150’s structure includes an additional benzoate ester group, which offers even more benefits like the ones we’re telling you about next.


Esterification is the process of adding an ester group to a compound. Researchers produce esters through a chemical reaction, usually of an acid (e.g., carboxylic acid) and an alcohol. This produces a more alkaline product.

In RAD-150, the increased alkalinity makes for a more stable compound. It also makes RAD-150 more similar to natural testosterone. That means it can bind better to androgen receptors.

Because RAD-150 is an anabolic ester, it tends to act faster and last longer than other SARMs. Anabolic compounds have increased bioavailability, meaning your body absorbs them quicker. They also have a longer half-life, which allows your body to eliminate them slower.

This is why you can expect RAD-150 research chemicals to take effect rapidly and last for 48 hours or longer. Overall, RAD-150 offers way more bang for your buck than non-esterized RAD-140.


Stacking SARMs together or alongside similar products produce synergies. Synergy refers to the fact that two chemicals together can sometimes produce more robust effects or added benefits than if those chemicals are used alone.

For example, stacking may:

  • Speed up recovery times
  • Boost fat loss
  • Enhance bulking cycles
RAD-140 and RAD-150 are ideal for stacking. Stack these SARMs with growth hormones or other bodybuilding supplements to harness these synergies and more.


Selective androgen receptor modulators can help you build strength and lean muscle while reducing fat content.

RAD-150 (TLB-150 Benzoate) is the latest SARM on the market. It promises even more impressive benefits. This includes a quicker onset and longer-lasting effects than any other SARM on the market.

Really interested in this one. Love the possibility of an increased libido as a bonus effect too! Just a little nervous about the possibility of insomnia as a side effect. It will be interesting to see how common that is.
Nice information on this new addition. Im looking forward to hearing about the results on this one
