YK 11 vs RAD 140 – Which is More Potent?

In this YK 11 Vs RAD 140 comparison you will find out what are the similarities and differences between these two SARMs that have become a major hit within the bodybuilding community.

YK 11 and RAD 140 are two of the most suppressive SARMs but you should never stack them since they can result in heavy testosterone suppression when used together. Even though stacking these two SARMs does not lead to a complete shutdown, it can certainly lead to a lot of other complications arising because of a nosedive in your endogenous testosterone production. When compared in terms of suppression, YK11 is more suppressive as compared to RAD 140.

YK 11 Vs RAD 140

Let’s examine and compare each of these two SARMs in a little more detail…

What is YK 11?

YK 11 is a powerful SARM that is also a myostatin inhibitor. Now, myostatin is a protein that inhibits muscle growth in your body. By inhibiting this protein, YK 11 allows massive muscle growth in your body. Thus, when it comes to building muscle, YK 11 happens to be one of the best SARMs that you can use.

Having said that, it is important to know that whatever data and facts are available about this SARM are through anecdotal evidence since clinical trials on YK 11 have been abandoned for a long time.

YK 11 consists of 4 methylated groups in its nomenclature and this is why it is likely to be hepatoxic. However, it is not massively toxic to the liver and your liver values will not massively jump because of it.

How does YK 11 work?

YK 11 is known to work by affecting the levels of two proteins in your body and these include:

• Myostatin – This is a protein that inhibits muscle growth.
• Follistatin – This is a protein that promotes both muscle and strength in your body.

YK 11 works by lowering myostatin and enhancing follistatin in your body and by doing so, it helps bodybuilders like you gain a lot more muscle and strength.

YK 11 produces direct androgenic and anabolic activity in your body and it is likely to cause hair loss too, as a side effect. The extent or severity of hair loss depends upon the dosage used.

What is RAD 140?

RAD 140 or Testolone is one of the most popular SARMs among bodybuilders mainly because it is known to result in dry muscle gains.

The main difference between YK 11 and RAD 140 is that while YK 11 works by inhibiting myostatin, RAD 140 is a pure SARM that acts as a partial agonist to the androgen receptor in your body.

Even though it implies that RAD 140 should be less suppressive as compared to YK 11, actual results may vary from person to person. There are guys who might experience more suppression on RAD 140 rather than on YK 11.

One of the key features of RAD 140 is that it is known to produce excellent results in terms of muscle gain even in low dosages.

Having said that, RAD 140 is also subject to the same issues as YK 11 – a lack of clinical studies done on humans to find out its real effects and side effects in the long term.

YK 11 Vs RAD 140 – Half-Life

Half-life, in layman’s terms, is the time that a compound stays active within your body. The dosage that you take depends entirely upon the half-life of the compound.

RAD 140 is a better performer as compared to YK-11 in terms of half-life.

The half-life of YK-11 is merely 12 hours. What it means is that you need to consume two doses in a day to ensure an optimal level of this compound in your body during a cycle.

On the other hand, RAD 140 comes with a much longer half-life of 60 hours. What it means is that even if you miss the daily dose of this compound, your body will still have a good enough concentration of RAD 140 in the bloodstream and thus, missing a dose should not be a matter of much concern.

YK 11 vs RAD 140 – Benefits Compared

Let’s compare the main benefits of both these SARMs to understand how each one of these can help you:

Muscle Mass

YK11 is the clear winner in this category. It is an excellent muscle gainer that works by affecting the level of two proteins in your body, as mentioned above. RAD 140 cannot measure up to the muscle gains that YK 11 ensures.

Users (in bodybuilding forums and other platforms) reveal that YK 11 can help them gain as much as 15 lbs of muscle in just an eight-week cycle. RAD 140, on the other hand, can help gain as much as 10 pounds of muscle in the same 8-week cycle.

Strength

Even though RAD 140 goes with the tag of Strength SARM, it doesn’t stand anywhere close to YK 11 when it comes to measuring the strength boost.

You are likely to experience a massive surge in your strength and power when on YK 11 and the best part is that you won’t even experience any kind of aggression or mood swings that are so popular with strength-boosting anabolic steroids.

RAD 140 can also help increase strength (but not to the extent YK 11 does) but it may also lead to aggression (which is so very typical of steroids and SARMs that increase testosterone levels in your body).

Vascularity

When it comes to measuring vascularity, both YK 11 and RAD 140 are good performers but RAD 140 emerges as the clear winner.

It is likely to lead to dry muscle gains and can also help burn excess fat resulting in enhanced vascularity so that you will have veins popping up all your muscles. YK11 falls quite inferior to this vascularity-enhancing effect of RAD 140.

Motivation

Both these SARMs are likely to increase your motivation to workout. They can surge your strength like anything and make you feel like a beast who’s ready to lift the heaviest dumbbells in the gym.

Comparing the two SARMs, YK11 is likely to be a better motivator simply because it is also a better strength booster. It can make you feel invincible and manly as if possessing Herculean strength!

Benefit Compared	YK 11	RAD 140
Muscle Gains	Excellent – May help gain up to 15 lbs in just an 8-week cycle	Very Good – May help gain up to 10 pounds in an 8-week cycle
Strength Gains	Incredible Strength Gains	Good Strength Gains
Vascularity	Good (falls short of RAD 140 here)	Excellent (ensured dry muscle gains)
Motivation	Excellent (because of massive strength gains)	Very Good (because of good strength gains)

YK 11 Vs RAD 140 – Side Effects Compared

Let’s check out how each of these SARMs fares in comparison to each other as far as side effects are concerned…

Testosterone Suppression

When it comes to suppressing testosterone, YK11 is likely to have a deeper impact as compared to RAD 140. As a matter of fact, RAD 140 suppression can be managed even without a PCT. There are bodybuilders who can actually get around with RAD 140 suppression by moderating the dosage as well as the length of the cycle.

Having said that, this is something that is simply not possible with YK11. You need to plan a PCT even before you begin your YK11 cycle. More often than not, you need to get on a 4-week PCT with Nolvadex after a YK11 cycle.

I must mention here that suppression can make you feel extreme lethargy and lack of motivation to workout. Not just this, it may also be accompanied with sluggish or poor libido, mood swings and even depression.

Aggression

As far as aggression is concerned, RAD 140 is the SARM that beats YK11 in its track. RAD 140 is likely to make you feel more irritable and on the edge ready to fight for trivial things.

YK11 does not make you feel aggressive or angry. It will make you feel more in control of yourself. There’s no doubt YK11 makes you feel more confident about yourself.

Liver Toxicity

YK11 is likely to be hard on your liver. This is because it has a methylated group added to it. What it means is that YK11 is a compound that comes laced with alcohol. It is common knowledge that alcohol is bad for your liver and this is why it is recommended that you go for liver support when on a YK11 cycle.

RAD 140, on the other hand, is not likely to be as hard on your liver. As a matter of fact, it does not lead to an increase in AST or ALT levels. Having said that, there’s always a possibility that things may go the other way. Thus, it is always better to opt for a hepatic panel before and after a RAD 140 cycle.

Joint Pain

This is something that you are more likely to experience when on RAD 140. This compound can make your joints hurt.

However, YK11 is likely to be much lighter on your joints. There’s little joint pain, if at all during a YK 11 cycle. This is because YK11 is known to strengthen bones while increasing muscle mass in your body.

Side Effect Compared	YK 11	RAD 140
Testosterone Suppression	Extremely Suppressive, Needs PCT	Quite Suppressive, May/May not need PCT (depending upon the dosage)
Aggression	Makes you feel less aggressive/angry	Extreme aggression
Liver Toxicity	Hepatoxic, Increases AST/ALT liver enzymes	Not hard on liver, May/may not increase liver enzymes (depending upon the dosage)
Joint Pain	Strengthens Bones, No/minimal joint pain	Makes Joints hurt

Conclusion

YK11 and RAD 140 are both excellent SARMs and they can be great for bulking. RAD 140, however, can be good for a cutting cycle too. It is likely to be the more versatile of the two SARMs. Since little is known about the side effects of these SARMs clinically, I would suggest that you try legal and safe alternatives that are not just effective and safe but also do not require a PCT!
