YK-11 Myostatin SARM

YK-11 is such a powerful SARM that you can actually talk of Bulking SARMs and YK-11 in the same breath. As a matter of fact, it happens to be the most powerful SARM that you can use to get jacked with lean, hard, and dense muscle. This is precisely the reason it has become so popular among bodybuilders and gymgoers.

One of the most important properties of YK-11 is that it can inhibit myostatin.

Since it is the most popular SARM for bulking that seems to be getting increasingly popular with each passing day, let’s delve a bit deeper and find out more about this SARM.

What is YK-11 Myostatin SARM?

No prizes for guessing that YK-11 is a SARM or a selective androgen receptor modulator. What it means is that it attaches to specific androgen receptors rather than affecting the whole of your body. This is unlike steroids that bear an impact on your entire body.

YK-11 Myostatin SARM

One of the most interesting features of YK-11 is that it is capable of inhibiting the activity of myostatin. It’s important to more that myostatin is a protein that is responsible for preventing muscle growth in your body. While it is great for boosting muscle growth during the bulking phase, it is equally good to consume during the cutting cycle it can prevent any loss of muscle.

It has been observed that YK-11 seems to have a geometric structure that is quite similar to anabolic steroids. This is why some people often argue that it is a synthetic steroid that has been mistaken for a SARM.

How Does YK-11 Myostatin SARM Work?

YK-11 works by affecting the levels of two proteins in your body and these include Myostatin and Follistatin.

Myostatin – This is a protein, as mentioned above, that prevents your body from building bigger and stronger muscles.

Follistatin – This is a protein that is known to promote both muscle and strength gains in your body.

YK-11 is a SARM that not only lowers the level of myostatin in your body but also works to shoot up Follistatin levels. What it means is that it reduces catabolic activity and enhances anabolic processes so that your body is in a better position to build muscle and strength fast.

I must mention here that clinical studies have shown that people who are able to limit the production of myostatin tend to be more muscular and stronger as compared to those that have normal levels of this protein.

Benefits Of YK-11

YK-11 Myostatin SARM

Here are some of the main benefits of YK-11 SARM:

Building Muscle, Prevent Muscle Loss

As mentioned above, YK-11 is often considered the best SARM for gaining muscle mass. As a matter of fact, it is a SARM that you can use in all sorts of bodybuilding phases or cycles that could include bulking, cutting, and recomposition phases.

This is because it helps your body build muscle during the bulking phase. It prevents muscle loss during a cutting cycle and also helps you stay lean and strong during recomposition or reconditioning of your body.

Increases Strength

Yet another significant benefit is it helps multiply your strength. It is not uncommon for users to increase their lifts by as much as 30-40 lbs within an 8-week cycle of this SARM. In other words, you can push more weight on the bench or lift heavier weights while squatting.

Strengthens Bones

Another major benefit that comes with this SARM is that it can help make your bones stronger by enhancing the levels of Protein Kinase B, which plays a critical role in the growth of bone cells in your body.

In addition to the above, YK-11 acts like testosterone in your body to boost muscle growth.

Is YK-11 Legal?

YK-11, like many other SARMs is only partially legal. What it means is that you buy it only for research purposes. Its use as a bodybuilding supplement is prohibited and illegal in most parts of the world.

I would also like to mention here that you cannot buy YK-11 in Australia without a prescription, where it is classified as a Schedule 4 prescription-only compound.

In other parts of the world, however, you can buy it only, only for research purposes.

I must also state here that YK-11 and other SARMs have been banned by the World Anti-Doping Authority (WADA) and any athlete found using it is liable to legal action including suspension.

Who Should Use YK-11?

First of all, what you need to understand is that YK-11 is a highly potent SARM and it’s not something that is meant to be used to or taken by beginners. If you are someone who is new to SARM then you must start with something that is on the milder side such as Ostarine MK 2866 and once your body gets used to it, gradually work your way up to potent SARMs such as YK-11.

YK-11 Myostatin SARM

To put it simply, YK-11 must be used by bodybuilders who have already used other SARMs such as Ostarine or even LG 4033 Ligandrol.

Moreover, any guy should not use it before he hits or while undergoing puberty. In such a case, one should allow natural body growth fueled by a surge in your testosterone and HGH levels.

Besides this, YK-11 should only be used by those guys who train regularly and take a proper diet too. It should be taken only when combined with these two and when you want to scale up your results from your training regime.

YK-11 Myostatin SARM Cycle

As far as the recommended YK-11 Cycle is concerned, I would say that you go for 10-15 mg of YK-11 per day for an 8-week cycle. Now, this is for guys who have used SARMs before and are used to taking them.

If however, it is your first cycle then you should begin with a dose that is as low as 5 mg per day for a period of 8 weeks.

The whole idea is that you should rush things and take them slowly. If you experience any discomfort or side effects, it is better to discontinue the SARM that you are taking.

YK-11 Dosage

The YK-11 Dosage that you take depends upon your body weight as well as your goal.

If you want to bulk up then you should consider a dosage of 10-15 mg per day for an 8-week cycle. However, the dosage is likely to depend upon your weight. If you weigh less than 200 lbs then you should not consume more than 10 mg per day and if your weight is more than 200 lbs, you should go for a dose of 15 mg per day.

If you want to take YK-11 during your cutting or recomp phase, try to stick to a dose of 5 mg per day.

YK-11 for Bodybuilding

YK-11 remains the top choice of many bodybuilders since it can be used for all three purposes – bulking, cutting, and reconditioning your body. What you need to keep in mind is that here’s a SARM that can prevent muscle loss by inhibiting Myostatin and also increase strength and muscle by shooting up the levels of Follistatin protein in your body. No wonder, it is often being acclaimed as top muscle and strength-boosting SARM.

YK-11 for Bodybuilding

As far as a cutting cycle is concerned, it will not actually help you lose weight or excess body fat but it will definitely be a massive help in preventing muscle loss when you are losing fat. 

You see, it is quite common for guys to lose muscle as they try to cut down on body fat. So, when you combine YK-11 with another SARM such as Andarine S4 for getting lean, you do not run the risk of losing your hard-earned muscle mass. 

As mentioned above, the ideal dosage that you need to stick to (when building muscle) is 10-15 mg per day and that too depends on your body weight. You need to run this cycle for 8 weeks at the most and you need to put yourself on a 4-week PCT of 20 mg of Clomid every day. Here, I should point ou that you need to begin with your PCT when you are done with 7 weeks of YK-11 or when you have one week left of the YK-11 cycle!

YK-11 For Cutting

YK-11 is not a SARM for cutting but you can certainly combine it with other cuttings SARMs in order to prevent any muscle loss that could occur when you try to lose fat.

WeekYK-11StenabolicS23
1-210 mg/day10 mg/day10 mg/day
3-415 mg/day15 mg/day10 mg/day
5-620 mg/day20 mg/day15 mg/day
7-825 mg/day25 mg/day20 mg/day

You can begin with Clomid 20 mg per day at the beginning of the 8th week of the above cycle and continue it for 4 weeks.

YK-11 for Women

Women too can use this SARM. However, it’s worth mentioning here that they should be using it in far smaller dosages as compared to men since women produce androgens in far smaller volumes as compared to men.

Typically, women can vary the YK-11 dosage from 0.5 mg per day to 2 mg per day. YK-11 is a SARM that is suitable for women in smaller quantities since they have relatively low androgenic effects.

YK-11 Stack

I must mention here that first-timers or beginners should actually avoid using YK-11 in a stack, rather they should use it alone at a low dose of about 5 mg per day for 8 weeks at the most.

Apart from the stack mentioned above, you can combine YK-11 with some other SARMs that could include:

  • MK 677
  • Cardarine and
  • SR9009

YK-11 Side Effects

YK-11 does not have side effects that inflict on your organs as is the case with anabolic steroids. Yet, there could be some minor side effects. I must mention here that a lot more study and research is required to study the side effects of SARMs.

According to anecdotal evidence some of the side effects of YK-11 could include the following:

  • hair loss
  • acne
  • aggressive behavior
  • decreased libido etc.

I must also state here that most of these side effects disappear when you stop having YK-11.

Moreover, YK-11 can lead to testosterone suppression in men and a drop in the libido is a direct result of that. This is why it is important to put yourself on a PCT post YK-11 cycle.

Is YK-11 Safe?

As far as the side effects are concerned, not much is clinically established. However, what is known is that with relatively low doses(such as those mentioned above), you are not likely to experience any severe side effects. Having said that, it is still possible that you might experience some minor complications such as hair loss and acne. 

People who are already prone to hair loss or acne are likely to experience a further aggravation of their condition.

However, these side effects are likely to wane off when you are done with the YK-11 cycle. 

I must mention here that it is important to follow a PCT after a YK-11 cycle or else you might experience a drop in virility as well as energy since there is a possibility of testosterone suppression with this SARM.

YK-11 Vs RAD 140

YK-11 Vs RAD 140

Testolone RAD 140 is another SARM that can be used for bulking up. Having said that, Testolone Results fall short when compared to the power of YK-11 and this is mainly because it can inhibit myostatin. At the same time, it can also increase Follistatin in your body promoting more muscle growth.

If you had to choose between the two SARMs, YK-11 is definitely a better choice.

Furthermore, I would like to mention that a RAD 140 stack with YK-11 could be a big mistake since both of these could have a suppressive effect and they can even lead to a testosterone shutdown. RAD 140 Suppression could be quite aggressive and, it is better not to stack  YK-11 with Testolone. In case you decide to do consume RAD 140, you must check out the PCT for RAD 140 beforehand.

YK-11 vs S4

Andarine S4 is another SARM that can be used for building lean muscle mass. However, it too cannot compete with YK-11 and its ability to increase muscle in your body.

Having said that, the side effects of Andarine S4 are likely to be much milder as compared to those of YK-11. So, you are not going to experience any hair loss or acne with this SARM. 

If you are not able to tolerate YK-11, you can certainly give Andarine S4 a try!

YK-11 vs Ligandrol

LGD 4033 Ligandrol is another powerful SARM for bulking up with muscle. It is also known to boost strength. However, it works differently from YK-11 since it does not inhibit myostatin in your body.

LGD 4033 is a better option for beginners or first-timers as compared to YK-11 because of the reasons that YK-11 is stronger and more potent and should be used by those that have already prior experience of taking SARMs.

YK-11 vs Ostarine

Ostarine MK 2866 is generally thought of to be the mildest SARM on the market and it also happens to be the first choice of beginners or first-timers for gaining muscle and strength.

So, if you are someone that is new to SARMs, you can begin with an Ostarine MK 2866 cycle and when your body gets used to it, you can advance to YK-11 in the next cycle.

Should You Take YK-11 Myostatin SARM?

A few facts check:

  • YK-11 is a better alternative to anabolic steroids. Compare SARMS with steroids here.
  • YK-11 has fewer side effects as compared to anabolic steroids.
  • YK-11 is still subject to a lot more research.
  • Not much is clinically established as far as side effects of YK-11 are concerned.
  • Anecdotal evidence suggests that there are side effects such as hair loss, acne, testosterone suppression, etc.
  • YK-11 is not approved by the FDA for use in bodybuilding supplements.

In view of the above facts, I would suggest that it is not a great option to take YK-11 for gaining muscle or strength. Even though it is being used by a lot of bodybuilders, its use remains illegal and unsafe.
