A. Introduction<\/h3>\n

YK-11 (Myostine)<\/b>\u00a0is one of the most complex compounds in the SARM category, distinguished by its unique steroidal backbone. Unlike non-steroidal SARMs, YK-11 is frequently studied for its dual-action potential as both a partial androgen receptor agonist and a potential myostatin inhibitor via the induction of follistatin. Our YK-11 powder is synthesized to meet the precise requirements of high-level genomic and proteomic research.<\/p>\n

B. Scientific Overview<\/h3>\n

Chemically identified as (17\u03b1,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester ($C_{25}H_{34}O_{6}$), YK-11 is a derivative of ethisterone. In\u00a0in-vitro<\/i>\u00a0laboratory settings, researchers investigate how YK-11 modulates the expression of myogenic regulatory factors. Specifically, it is utilized to study the up-regulation of\u00a0Follistatin<\/b>, a glycoprotein that acts as an antagonist to Myostatin.<\/p>\n
