YK-11 (5mg/capsule), 60 Capsules
During our packaging transition, you may receive products with either our previous or updated label. Rest assured, the formulation, purity and quality remain exactly same as standards.
YK-11 is a synthetic steroidal compound that functions as a gene-selective partial agonist of the androgen receptor (AR). Experimental investigations have reported interactions with androgen receptor-mediated transcriptional regulation together with modulation of follistatin (FST)-associated gene expression pathways. Follistatin is a regulatory glycoprotein involved in activin-associated signaling networks and transcriptional control processes, making YK-11 a useful research tool for examining AR-dependent gene regulation and downstream signaling mechanisms.
Research applications include androgen receptor pharmacology, AR partial agonism studies, follistatin-associated pathway investigation, transcriptional regulation research, structure-activity relationship analysis, and mechanistic comparison of steroidal and non-steroidal androgen receptor modulators.

What distinguishes YK-11 from other androgen receptor modulators?
YK-11 is notable for its gene-selective partial agonism at the androgen receptor (AR) together with reported modulation of follistatin (FST)-associated transcriptional pathways. This combination of receptor-mediated signaling and follistatin-associated gene regulation differentiates YK-11 from many other androgen receptor modulators and has made it a valuable research tool for investigating AR-dependent transcriptional mechanisms, regulatory signaling networks, and pathway-specific gene expression processes.
Is YK-11 a steroidal or non-steroidal androgen receptor modulator?
YK-11 is classified as a steroidal androgen receptor modulator and is structurally derived from the androstane scaffold. This steroidal framework distinguishes it from non-steroidal androgen receptor modulators that utilize alternative chemical architectures. The structural differences between steroidal and non-steroidal compounds make YK-11 useful for structure-activity relationship investigations examining receptor binding characteristics, co-regulator interactions, transcriptional responses, and androgen receptor pharmacology.
Why is follistatin-associated signaling relevant in YK-11 research?
Follistatin (FST) is a regulatory glycoprotein involved in activin-associated signaling systems and transcriptional control processes. Experimental investigations involving YK-11 have examined relationships between androgen receptor activation, follistatin-associated regulatory pathways, and downstream gene expression mechanisms. These characteristics have established YK-11 as a useful research tool for studies of AR-mediated signaling, transcriptional regulation, and the molecular interactions linking androgen receptor activity with follistatin-associated pathways.
