What Is YK-11 (Myostine)?
YK-11 is a synthetic research compound that acts on the androgen receptor. Some suppliers also call it Myostine. The name YK-11 comes from Yuichiro Kanno, the Japanese scientist who first described it. All of these names refer to the same molecule.
Kanno and his colleagues at Toho University reported the compound in 2011. Since then, it has appeared in a small but growing number of laboratory studies. Today, it is one of the more unusual compounds in androgen receptor research.
A Steroidal SARM
What makes YK-11 unusual? Most SARMs, such as Ostarine or RAD-140, are non-steroidal. YK-11, on the other hand, has a steroid backbone. It is built on the structure of 5α-dihydrotestosterone (DHT). Even so, it is described in the literature as a partial agonist of the androgen receptor. This rare mix of features is the main reason researchers find it interesting.
How Does YK-11 Compare to Other SARMs?
Because of its steroidal structure, YK-11 is often studied next to non-steroidal SARMs. These comparisons help researchers understand how structure affects receptor activity. In addition, YK-11 is notable for a reported link to follistatin, which is covered below. You can view related products in our full range of SARMs for sale.
YK-11 Research Background
Almost all published work on YK-11 comes from cell-based studies. The sections below summarize the main areas scientists have explored. This overview is for background only. It does not suggest any use outside the laboratory.
Androgen Receptor Activity
First, the original 2011 paper described how YK-11 binds to and activates the androgen receptor. The researchers found that it acted as a partial agonist in their assays. They also reported that it did not trigger the full set of receptor interactions seen with DHT. These early results defined its basic profile.
Follistatin Studies in Cell Models
Next, a 2013 study in the journal Biological and Pharmaceutical Bulletin used mouse C2C12 myoblast cells. In that cell model, the researchers reported that YK-11 increased the expression of follistatin. Follistatin is a protein that interacts with myostatin signaling. This finding is the reason some suppliers use the name Myostine.
Bone Cell Research
In addition, a later study examined YK-11 in mouse osteoblast cells. Osteoblasts are the cells that build bone tissue. The researchers looked at androgen receptor signaling pathways in this cell type. Like the earlier work, this study was carried out entirely in vitro.
Limits of the Current Evidence
Finally, it is important to be clear about what is not known. YK-11 has never entered a clinical trial. In fact, there is no published controlled human data on the compound at all. It is not approved by the FDA for any use. Meanwhile, published case reports describe liver injury in people who used SARMs outside of clinical studies. Given how little is known, YK-11 belongs only in controlled research settings.
To read the original papers, search PubMed for “YK11”. Because the literature is small, reading every primary source is both practical and worthwhile.
Why Buy YK-11 from Chemyo?
Many websites list YK-11 for sale. Yet independent tests of the SARM market have found serious quality gaps. Some products hold far less compound than their labels claim. Others contain a different substance entirely. That is exactly why testing and transparency guide everything we do.
99% Purity, Verified by Independent Testing
Every batch of our YK-11 is analyzed by [LAB NAME], an independent laboratory. The lab uses high-performance liquid chromatography (HPLC) to confirm identity and purity. Our YK-11 consistently tests at 99% purity. Moreover, no batch is released until its results come back.
Precise 10mg Capsules, 60 per Bottle
Each capsule holds exactly 10mg of YK-11. Pre-measured capsules remove the need to weigh tiny amounts of powder. Therefore, you save time and lower the risk of measuring errors. With 60 capsules per bottle, you also get plenty of material from a single batch.
Batch-Matched Certificate of Analysis
Every bottle carries a batch number. That number matches the certificate of analysis on this page. In other words, you can check the exact report for the exact product you receive. View the current report here: YK-11 COA, batch [BATCH #].

Our Quality Control Process for YK-11 for Sale
Before any YK-11 for sale reaches our shop, it passes four documented steps. Thanks to this process, we can trace every bottle back to its source.
- Sourcing: we buy raw YK-11 only from vetted manufacturers with a proven track record.
- Testing: next, an independent lab confirms identity and purity by HPLC.
- Encapsulation: after that, the material is filled into 10mg capsules under controlled conditions.
- Release: finally, we publish the COA and assign the batch number printed on each bottle.
If a batch falls below our 99% standard, we reject it. We never blend it, and we never relabel it. This strict rule is why labs return to us whenever they need YK-11 for sale they can rely on.

Storage and Handling
Proper storage keeps your material in good condition. Keep YK-11 capsules in their original sealed bottle. Store the bottle in a cool, dry place between 15°C and 25°C. Also, keep it away from direct light and moisture.
After opening, close the lid firmly after each use. Avoid humid spots, such as near a sink or a window. Stored this way, the capsules stay stable until the date printed on the label.
Lastly, follow standard lab safety practices with every research compound. Wear gloves, label containers clearly and keep products away from children and pets. Only qualified professionals should handle this material.
