Overview

YK11 was first researched by Yuichiro Kanno in Japan in 2011. It is identified as a partial agonist of the androgen receptor (AR) with selectivity for genes, leading researchers to classify it as a SARM. YK11 is an experimental drug candidate and an unapproved substance for human use. To date, there have been limited studies, though initial findings in muscle cells are very promising. Preliminary research suggests that YK11 may have a greater muscle-building potential than DHT and a tendency to act as a myostatin inhibitor.


Mechanism of Action

Myostatin is a protein that limits muscle growth to ensure muscles do not grow "too large." It is primarily found in skeletal muscle, and studies have shown that individuals with genetic mutations that limit myostatin production are stronger and more muscular than those with normal levels.


YK11 may inhibit myostatin production in muscles by binding to androgen receptors. It could induce muscles to produce more follistatin, which in turn limits myostatin levels, allowing for muscle growth beyond genetic capabilities. YK-11 suppresses myostatin, which means muscles can grow increasingly faster.


One of the most commonly reported effects of YK-11 is an increase in pump and muscle fullness, with many users claiming this effect to be greater than when stacking with other muscle-building compounds. YK-11's muscle growth capabilities far surpass those of other SARMs when compared to testosterone.


Side Effects

YK11 has a steroidal structure, which sets it apart from typical SARMs. The main side effects of YK11 include:

  • Testosterone Suppression

    Some international users report a decline in endogenous testosterone levels after using YK11 for 6-8 weeks. However, compared to other steroids, this suppression is not severe and can be easily recovered with the help of PCT.

  • Liver Toxicity


  2. While most SARMs do not deal with this issue; due to its steroidal nature and chemical closeness to steroids, YK11 can stress the liver, hence it is advised to include liver protection during its use.






  • Joint Pain


  2. This is a common issue reported by users abroad who have used YK11.



  • Hair Loss and Mild Acne


  2. These are mostly due to excessively high doses or extended cycles of YK11; strict control of dosage can minimize these risks. YK-11's half-life is only 6-8 hours, so dosing should be at least twice daily.

YK-11 Dosage:

For most users, starting with 10 milligrams per day is recommended, split into 5 milligrams in the morning and 5 milligrams in the evening due to its short half-life. Some have used up to 25 milligrams per day, showing significant muscle progress.

Usage Cycle Suggested:

Weeks 1-4: 5 milligrams in the morning, 5 milligrams in the evening.

Weeks 5-8: Increase the daily dose to 15mg; 5mg in the morning, 5mg pre-workout, and 5mg in the evening.

Weeks 8-12 (optional): Increase the dose to 20mg per day; 5mg in the morning, 10mg pre-workout, and 5mg in the evening.


Is YK-11 Suitable for Bulking or Cutting?

This SARM is versatile and can be used for both purposes. However, lower dosages are recommended during cutting phases to maintain as much muscle mass as possible. If bulking, assess your tolerance and, if comfortable, increase to 20 milligrams per day. Many users also like to stack it with LGD 4033.


Expected Results:

What results can be expected from using YK-11? This largely depends on your training and diet, as well as the dosage used. If the average dosage is 10 milligrams per day, you can expect:

  • Bulking phase: It's very possible to gain 10 pounds of muscle in 8 weeks, with proper diet control and high protein intake, almost without any fat gain.



  • Cutting phase: By reducing total caloric intake to 500-1000 calories below your TDEE, you can gain 5 to 10 pounds of muscle while simultaneously losing 5 to 10 pounds of fat.



Side Effects:

Another nice aspect of this SARM is that it does not have the severe side effects common with steroids or other powerful SARMs, such as hair loss, gynecomastia (man boobs), or suppression of the gonadal axis. Some people may experience diarrhea while taking YK-11, which is the worst condition reported but is nearly tolerable compared to the side effects of steroids.


Common Questions:

  • Do you need to do PCT with YK-11?


  2. No, YK-11 does not shut down your body’s testosterone production, and no post-cycle therapy is needed after use.










  • Can you stack YK11 with LGD 4033 or Test?


  2. Yes, stacking YK-11 with LGD 4033 is very popular, and it can also be stacked with Test E. The main benefit of YK-11 is that it stacks well with other steroids and compounds.







  • Does YK-11 cause gynecomastia (gyno)?


  2. Absolutely not, YK-11 or any other SARMs do not convert to estrogen, hence no risk of gynecomastia.






  • Is YK-11 safe?


  2. Yes, it is very safe if used responsibly. Drink plenty of water, monitor your body carefully to ensure there are no adverse reactions, and stop taking this and all other SARMs immediately if something feels off and consult a doctor.


Conclusion:

YK-11 is excellent for those looking to gain strength, muscle mass, and muscle definition. It is very safe, versatile, and easy to dose. It can be used alone or stacked effectively with other performance-enhancing drugs.
