YK11 is often classified as a Selective Androgen Receptor Modulator (SARM), similar to compounds like LGD-4033 or Ostarine. However, it's important to note that YK11 is unique compared to other SARMs as it is also considered a myostatin inhibitor.
Myostatin is a protein that regulates muscle growth, and inhibiting it could potentially lead to increased muscle development. YK11 is believed to interact with androgen receptors in muscle cells, promoting muscle growth and potentially enhancing athletic performance.
It's worth noting that the use of YK11 and other SARMs is a topic of controversy and concern. As of my last knowledge update in January 2022, there is limited research on the safety, efficacy, and long-term effects of YK11, and it's not approved for medical use in many countries. Additionally, the legality of these substances can vary by jurisdiction.
If you are considering the use of YK11 or any similar compound, it's crucial to consult with a healthcare professional. Misuse or improper use of such substances can have adverse effects on health, and their use is often associated with potential legal and ethical issues

| Description | YK-11 is a synthetic steroidal selective androgen receptor modulator (steroidal SARM). It is a steroid compound based on 5-α-dihydrotestosterone (DHT), which is a gene-selective and partial agonist of the androgen receptor (AR). YK11 is so far the only SARM that is able to increase the expression of the activin binding protein Follistatin (FST), and right the induction of FST plays a key role in its anabolic effects. YK11 has chemical formula C25H34O6 and molecular mass 430.541 g·mol?1. |
| Uses | YK11 is a steroidal SARM (Selective Androgen Receptor Modulator). More specifically, it’s a Myostatin inhibitor. It’s considered to be one of the most powerful SARMs on the market and it’s actually comparable to certain steroids in its effectiveness. YK11 is also a myostatin inhibitor (myostatin reduces our muscle mass), which means that you won’t be losing muscle while cutting and will very likely gain some instead, making it a great compound for cutting, lean bulking and especially body recomposition. |
| benefits | Well there are a few obvious benefits to taking a daily supplement designed to help build muscle. First and foremost, YK-11 helps you grow more muscle in a smaller amount of time. YK-11 is a myostatin inhibitor which makes it easier for your body to develop more muscle. In addition to more bulk, your muscles will become stronger from the production of follistatin. So as you can imagine, the stronger your muscles are the more you can do with them. Like steroids, YK-11 and other SARMs promote bone health and can make your bones stronger. As mentioned earlier, YK-11 also helps with fat loss by replacing that fat with muscle.There are also claims that YK-11 helps boost libido and that it allows you to work out harder and longer. YK-11 can also help you retain the muscle that you have built. |
| Side effects | Possible side effects of YK11 have not yet been scientifically investigated (at all). Theoretically, also the following side effects are not excluded: Suppressed levels of natural Testosterone in the body (quite likely) Increased risk of heart attack and stroke Liver toxicity (due to the structure derived from DHT) Can increase the progress of some cancer types (due to the increased expression of Follistatin) The bodybuilding community on the Internet has experienced and reported with respect to YK11 some typical side effects, that occur with steroid use: Mild testosterone suppression Fatigue, low energy level Aggression Joint pain Excessive hair loss Mild acne |
