YK-11 is a steroidal SARM so works a little differently than many other popular SARMs. It is a partial agonist of the androgen receptor and is often described as a hybrid between a steroid and a SARM.
YK-11 is very much a research SARM and while some other compounds have moved towards human studies and trials, research on YK-11 has stalled in its infancy with no scientific validation of what it can and can’t do, and no hard evidence of potential short term side effects or long-term health impacts. This means that anecdotal evidence from users of YK-11 and their personal experiences is the main form of information about this compound.
This gives us a good idea of what YK11 is capable of, however it should always be kept in mind that you could personally experience effects – either good or bad – that have not been shared by other users and this is one of the risks that comes with using a research compound like YK-11.
What we do know is that YK11 is great for making mass gains, can assist with fat loss, and helps shape the physique with no fluid retention. For these reasons it appeals to both bulking and cutting goals, while also being a compound that females can use.
