YK11: The Complete

Every bodybuilder dreams of acquiring a physique that is high on muscle, low on fat and gives them the ability to push themselves to new heights.

While there are many steroids available in the market that can help you build a body like that, they also bring along with them a number of side effects that are just not worth the risk.

However, with a supplement like YK11, you will be able to gain a body that will allow you to reach your fitness goals, fill you with stamina and lean muscles, without the chances of serious side effects. YK11 is a revolutionary supplement that has miraculous benefits and has next to no side effects!

What is YK11?

While many carry the assumption that YK11 is a regular SARM supplement, it is quite far from it. Due to its steroid hybrid status, it is also described by many as ‘super SARM’.

YK11, also known as Myostine, is actually a Myostine inhibitor. This means that it is able to break down your genetic muscle-building wall and allows you to gain more muscle mass than what you would have gained without taking YK11 throughout your workout.

Is YK11 a SARM or Myostatin Inhibitor?

The debate on whether YK11 is a SARM or Myostatin inhibitor is still fresh. The theory of it being a myostatin inhibitor arose after a cellular study. In the study, it was found that YK11 increases muscle mass by enhancing the growth of follistatin in your body, an essential protein building protein.

On a different study, it was discovered that YK11 stimulates bone-building proteins, which is a common trait of SARM supplements.


Though SARMs have been in the market for quite some time and have been making their presence felt with its low side effects and high level of benefits, YK11 is still a newbie in the market. This is the main reason why there’s such limited research done on the compound as of now. Accurate numbers and data about YK11 are yet to be found and studied.

In 2011, Yuichiro Kanno identified the miraculous benefits of YK11. He conducted multiple studies and research on the compound and published results which identified it as a drug that brings along a handful of excellent benefits.

How Does YK11 Work?

As mentioned earlier, taking YK11 releases a compound called follistatin in your body. This is a compound that prevents Myostatin from destroying your muscle gains, promotes a better gain of muscle mass and lean growth of the body.

YK11 strengthens your muscles in the same manner as testosterone. However, YK11 does not cause harmful side effects as high doses of testosterone does on your body.

YK11 helps build your stamina. When you are at the gym, following your everyday lifting regime, your body will be able to push itself to new extremes with a dose of YK11. It helps to change your body’s genetics, promoting better muscle building and better performance.

How Long Does It Take To Start Working?

If you follow the right cycle length of YK11, which is 6-8 weeks, depending on if you are a beginner or an experienced user, you will witness a boost in your energy levels as soon as you head over to the gym after taking your dose.

It shows immediate results right after you take it. Just make sure that you follow the recommended quantity of dose and take support supplements.

Benefits Of YK11

Muscle Protection

YK11 plays the role of a protective agent for the muscle mass you already had before starting the cycle. When you exercise every day and cut down on calories at the same time, it affects your muscles significantly, this is where YK11 comes to the rescue.

When you take YK11, your body doesn’t suffer such issues and helps you generate lean muscle growth and preserve your muscle mass, all at the same time. YK11 does this by blocking the generation of Myostatin in your body.

Losing Weight

YK11 promotes the burning of calories, which directly impacts your weight loss progress. Since it generates enhanced muscle mass, it then promotes more calories to be burned every day from your physical activities.

This is because each pound of muscle requires calories to feed it to keep it alive. So when you build new muscle you are actively increasing your metabolism as this muscle needs calories.

Prevention From Certain Types Of Cancers

YK11 generates a compound called follistatin in your body, and it has been proven through studies that a high level of follistatin could help you fight against a certain set of cancers, which are:

  • Breast cancer
  • Ovarian cancer
  • Liver cancer
  • Non-small cell lung cancer

Stronger Bones

Studies have shown that the intake of YK11 can actually enhance your bone strength by binding itself to your androgen receptors. YK11 also increases the level of activated PKB, which stands for protein kinase B, to promote healthy bone growth.

Half-Life Of YK11

Due to lack of proper research on YK11, the exact half-life of the supplement is unknown. To be on the safe side, experts recommend splitting your dosage into two in order to enhance its half-life and prevent your blood level from fluctuating.

It is advised that there should be a gap of at least 10 hours between the two doses.

Events showcase that the half-life of YK11, though unknown, is pretty short, therefore, it is better you make it a routine to take it in two doses daily to avoid any risks.

When To Take?

YK11 should be taken in a strict schedule. Taking the doses without a set pattern can prove to be damaging for your health and your body.

Hence, it is important that you carry out the dosage for 6 to 8 weeks and split the daily dose into two different doses.

These two doses should be taken at least 10 hours apart. This will allow your body to stabilize its hormonal levels and enhance the half-life of YK11, facilitating better effects of the supplement on your body.

Is YK11 Safe For Women To Use?

YK11 is one of the strongest SARMs supplements available in the market today. This might lead you into thinking that it would carry a bundle of side effects for female users, but this is not the case.

Although YK11 is quite strong, it doesn’t carry any virilization effects. Thus, female users can use it without having to worry about any gender-specific side effects.

It is advised that female users take the recommended dosage of 0.5 to 2.0 mg per day, divided into two doses.

Cycle Length Of YK11

The cycle length of a supplement is very important to be studied in order to maximize the results and to prevent yourself from any possible health risks.

The cycle of a supplement means the period of time you choose to take the dose for and in what quantities. Both of which are recommended by experts or past users to ensure safety.

There are two ways in which you can carry out your YK11 cycle:

  • The first kind of cycle lasts for 6 weeks and the recommended dosage is 5mg per day, advised to be split into two doses. This cycle is often used by people who are using YK11 for the first time. Beginners are always advised to start off their journey with the supplement with a smaller quantity.
  • The second one lasts for 8 weeks with a recommended dosage of 10 to 15 mg per day, advised to be taken in two different doses as well. This cycle is carried out by experienced users of YK11. When you take a higher quantity of the supplement, it is important to increase the length of the cycle as well.

What Stacks Well With YK11?

Stacking is a process of combining multiple supplements to enhance the results and ensure that you get the maximum benefits of all the supplements involved.

It is always better to start off small and take the advice of your doctor or an expert so that it doesn’t affect your health.

Though YK11 is pretty strong and effective to be used alone, there are some supplements that amplify its effect on your body.

Many users combine YK11 with RAD140 to get better results. The dosage quantity for this combination should be:

YK11: 5 to 10 mg

RAD140: 15 to 30 mg.

It can also be stacked with LGD-4033, also known as Ligandrol – a supplement which is known for its ability to enhance lean muscle gain.

Past users report that taking LGD-4033 with YK11 helps to gain lean muscle mass in a short period of time. The dosage quantity for this combination should be:

YK11: 5 to 10 mg

LGD-4033: 5 to 15 mg.

Is PCT Needed After Using This?

PCT stands for Post Cycle Therapy, a method used by steroid users to quicken the hormonal recovery of their body after completing a cycle.

It is important to carry out PCT after taking any anabolic supplement as it prevents your muscles from breaking down and ensures that you have enough energy to carry out your everyday tasks, helping your body settle back into its normal hormonal setting.

Like all anabolic steroids, it is recommended that you take a PCT after completing your 6 or 8 week long YK11 cycle as well. A light PCT of 4 weeks should be suffieicnt.

Possible Side Effects

Though YK11 comes with many miraculous benefits, you can’t turn a blind eye to the possible side effects that the supplement might carry.

Hair Loss

Some users reported that they experienced major hair loss after taking the supplement. On the other hand, some users claimed that it caused them zero hair loss. Thus, it could be a person to person effect of YK11. So, if you are prone to hair loss, YK11 might amplify it further.

Suppression of Testosterone

Most anabolic steroids are claimed to suppress the level of testosterone in the users’ body and YK11 is no exception.

While it might affect your testosterone levels, it is important to note that with the right post cycle therapy and support supplements, our body can bounce back to its normal testosterone levels and recover quickly.

Liver Damage and Toxicity

It has been suggested that the use of YK11 can cause liver damage. With the right cycle support products and giving your body ample time to repair after the cycle is complete, you can reverse the liver toxicities in most cases.

Thus, it is important to take a liver cleansing supplement such as milk thistle whilst on cycle.

High Blood Pressure

Whenever a new foreign substance enters your body, there is a chance of your blood pressure hiking up and you can experience the same with YK11 as well. So, if you already suffer from high blood pressure issues, then it is better to take your doctor’s advice before starting the cycle.


Like most steroids, YK11 is suggested to reduce your sex drive. Thankfully, it has been found that it mildly decreases your sex drive in comparison to other steroids.

This is due to the lowering of your testosterone levels. Once the cycle ends and PCT is completed your previous libido should return fully.

Is It Legal?

Though it is not yet sold for human consumption directly in pharmacies, YK11 is legal and can be purchased from a number of research companies for research purposes only. But like any SARM or steroid, YK11 is prohibited in professional sports and has been banned by the WADA.

If you wish to stay away from steroids but also want to gain some of the benefits they bring, then YK11 is a great alternative for you, as it has many steroid-like effects without their damaging side effects.

Although the research for YK11 is still not developed to the fullest, it has already shown some significant results. Moreover, taking a small dosage of the recommended amount doesn’t cause any serious harm.

While there might be a few potential side effects that YK11 might bring, they depend on a person to person basis. These potential side effects can be suppressed with the right post cycle therapy and support supplements.

As of now, you can try out this supplement and experience the changes for yourself.
