YK11 SARM – 10MG/ML – 60ML BOTTLE

(17α,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester, more commonly known as YK11, is a potent non-steroidal selective androgen receptor modulator (SARM) that shows potential in improving anabolic activity in muscles and bones while decreasing overall fat mass. Initial research has found that YK11 increases levels of follistatin, resulting in the inhibition of myostatin. This mechanism of action is important to mention considering that high levels of myostatin have been shown to suppress excessive muscle growth. Additionally, YK11 is able to activate pathways that respond in a manner similar to testosterone and DHT. For example, administration of the SARM activates protein kinase B and ultimately results in enhanced osteoblast activity and increased bone density.
