ANABOLIC · STEROIDAL SARM · ORAL · T½ NOT ESTABLISHED
also: myostine · YK11
YK-11 is a synthetic steroidal compound characterised as a gene-selective partial agonist of the androgen receptor with reported effects on follistatin expression in cultured myoblasts. There are no published human trials, no human pharmacokinetic data and no human safety data, so nothing about its behaviour in people can be stated from evidence.
// our evidence grade — unedited
The entire evidence base is a small number of in vitro cell-culture papers from a single research group plus limited animal work, with no human trial of any kind and no human pharmacokinetic or safety data whatsoever.
We grade this compound and we sell it. The grade is set against our published criteria before any stocking decision and is not adjusted because it is in the catalogue.
