How To Run RAD-140

For recreational and competitive bodybuilders, enhancing both performance and physique results is a common goal.

For many of these athletes, selective androgen receptor modulators, or SARMs, are helpful. SARMs offer an excellent and relatively safe way to assist those in physique and strength sports. SARMs have gained in popularity over the past decade. This is because of their ability to provide similar results to anabolic steroids without any of the serious side effects that steroids can cause.

RAD 140, also called Testolone, has been shown to increase endurance as well as speed and power. It also supports enhanced muscle growth and recovery.


While much of the general research on SARMs focuses on their mechanism of action and on their effects as a whole, experienced SARM users have noted that different SARMs have slight benefits in certain areas. For instance, ostarine is generally known as being especially useful as a cutting and recomp drug. Ligandrol (also called LGD 4033) is well-suited to bulking.

There is less of a general consensus on RAD 140, simply because this is such a new supplement. But with a 90:1 anabolic to androgenic ratio, it has the potential to create muscle growth similar to testosterone. Some users have noted that RAD 140 seems to improve speed and endurance as well. This supplement shows potential as an all-around performance enhancer as well as the potential for building muscle.


How Does Rad 140 Work?

Because it is part of the class of selective androgen receptor modulators, RAD 140 works similarly to most SARMs. Like other compounds in this class, RAD 140 interacts with androgen receptors, but it interacts almost exclusively with the receptors in muscle and bone.

This general idea of how RAD-140 and other SARMs work explain the name “selective androgen receptor modulator.” This class of compounds is selective (because it targets only the androgen receptors in muscle and bone), and it causes receptor modulation (because it appears to alter the shape of the androgen receptor once it’s bonded to it).

The effects

RAD-140, because of its influence on androgen receptors, can also increase a user’s response to training. This means that if you use an identical training and diet regimen without RAD-140 and then use the same regimen with it, the RAD-140 will amplify your results. All other things being equal, you’ll see more form your diet and training when you pair it with a well-thought-out cycle of this supplement

However, like other compounds in this class, RAD-140 can also improve the strength of tendons and ligaments. For anyone who strength trains, this is a valuable effect. As bodybuilders make gains in muscular size and strength, it is vital that the tendons and ligaments also gain strength. Anyone who has suffered a tendon or ligament injury knows that healing can be a lengthy process. It also can lead to permanent damage and can severely hinder training.

RAD-140 has several benefits in terms of boosting speed and power. At first glance, it may seem as though this doesn’t matter for bodybuilding. But an increase in energy and endurance can help support increased training intensity. This is helpful for those who are training on reduced calories during a cut. RAD-140 can help users maintain existing muscle mass while cutting as well. The combination of these effects makes it ideal for a bodybuilder in a cutting phase. While its effects have the potential to dramatically increase results, this supplement has virtually no side effects. This is part of what makes it so attractive to athletes


Using RAD-140, unlike using anabolic steroids, does not cause enlargement of the prostate or dangerous effects on cardiac health. It does not cause testosterone suppression and also does not cause gynecomastia. This is because it is not converted to estrogen. This benefit is key for male bodybuilders, as once gynecomastia becomes severe, it necessitates surgical treatment.

RAD-140 manages to spare its users almost all of the negative effects of anabolic steroids. But one of the most important effects it avoids is that of liver toxicity. Steroids have an attached methyl group, which is toxic to the liver. RAD-140 and other SARMs, on the other hand, are non-methylated, meaning they are not very toxic to the liver if at all. In a similar vein, RAD-140 does not cause the cholesterol imbalances that steroids can cause.

The cycle

RAD-140 is effective with dosages as low as 10mg but the “sweet spot” is around 20-30mg per day.

We would recommend a cycle of between 6-8 weeks dosing once per day as RAD’s half-life is rather lengthy.

PCT is recommended due to RAD being slightly suppressive. Although suppression is unlikely, we would complete the full PCT just to ensure there are no issues post cycle and that you recover as quickly as possible

Look to use a product containing around 75mg’s of Arimistane and then potentially alongside this some Bulbine or D-Aspartic acid. A product like the Warrior Project Aftermath is a great all-in-one option.


With RAD-140, you can expect to replicate the therapeutic benefits of real Testosterone

Here’s a solid cycle using RAD-140 for anyone looking to Bulk or re-composition:

Week 1-8: RAD-140 20mg per day dosed once per day in the AM

Week 1-8: MK-677 20mg per day dosed once per day pre-bed

(Mini-PCT) Week 9-12: 2 servings Aftermath PCT dosed once per day in the AM


*Optional* Week 9-12: MK-677 20mg per day dosed once per day pre-bed (MK-677 is a GH Secretagogue, not a SARM, so it doesn’t cause testosterone suppression and can be used during PCT or even after PCT to help maintain your SARM gains, or even continue making more gains on its own)


In conclusion, RAD-140, while it is still a very new supplement, shows considerable promise for use in bodybuilders and other athletes. Few supplements offer the combination of muscle-building advantage and lack of side effects that SARMs do.

But this supplement is unique among SARMs – with an anabolic:androgenic ratio of 90:1, this supplement offers anabolic potential close to that of testosterone without the potentially deleterious side effects of excess testosterone supplementation. It’s also legal to buy and requires no needles. Add in the potential health benefits, and you have an extraordinary supplement.
