It\u2019s a synthetic steroidal selective androgen receptor modulator. Unlike traditional selective androgen receptor modulators, YK-11 works as a selective androgen receptor partial agonist and myostatin inhibitor.<\/p>\n<p class=\"wp-block-paragraph\">It\u2019s derived from dihydrotestosterone (DHT) and has a steroidal backbone that differentiates it from non-steroidal research compounds in the same category. This experimental substance was first synthesized by Japanese researcher Yuichiro Kanno in 2011, a big step forward in selective androgen receptor research applications.<\/p>\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/lotilabs.com\/buy\/yk-11\/\" rel=\"noopener noreferrer\" target=\"_self\">YK-11<\/a> is research only and not for human consumption. Labs using this compound must follow strict research protocols and regulatory compliance. The compound is classified as an experimental research chemical and requires proper handling and documentation for all research applications.<\/p>\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/lotilabs.com\/buy\/yk-11\/\" rel=\"noopener noreferrer\" target=\"_self\"><strong>CLICK HERE TO BUY YK-11 FROM LOTI LABS<\/strong><\/a><\/p>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Molecular_Structure_and_Chemical_Properties_of_YK-11\"><\/span><span class=\"ez-toc-section\" id=\"Molecular_Structure_and_Chemical_Properties_of_YK-11\"><\/span>Molecular Structure and Chemical Properties of <a href=\"https:\/\/lotilabs.com\/buy\/yk-11\/\" rel=\"noopener noreferrer\" target=\"_self\">YK-11<\/a><span class=\"ez-toc-section-end\"><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/lotilabs.com\/buy\/yk-11\/\" rel=\"noopener noreferrer\" target=\"_self\">YK-11<\/a> has CAS number 1370003-76-1 and has a molecular structure that research shows is responsible for its mechanism of action. The molecular formula C25H34O6 corresponds to a molecular weight of 430.54, with elemental composition of 69.74% carbon, 7.96% hydrogen and 22.30% oxygen. The steroidal backbone differentiates it from non-steroidal selective androgen receptor modulators used in research.<\/p>\n<p class=\"wp-block-paragraph\">The methylated structure of<a href=\"https:\/\/lotilabs.com\/buy\/yk-11\/\" rel=\"noopener noreferrer\" target=\"_self\"> YK-11<\/a>, specifically the 17\u03b1-alkylated configuration, affects its oral bioavailability in research models. Research shows that this structural modification makes the compound more resistant to hepatic metabolism than non-methylated counterparts. YK-11 dissolves in DMSO up to 64.0 mg\/mL, corresponding to 148.65 mM, which is convenient for most research applications.<\/p>\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<tbody><tr><th colspan=\"1\" rowspan=\"1\"><p>Property<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>Value<\/p><\/th><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Molecular Formula<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>C25H34O6<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Molecular Weight<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>430.54 g\/mol<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>CAS Number<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>1370003-76-1<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>DMSO Solubility<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>64.0 mg\/mL<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Structure Type<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Methylated Steroidal<\/p><\/td><\/tr><\/tbody>\n<\/table>\n<\/figure>\n<p class=\"wp-block-paragraph\">Hepatic metabolism and renal\/biliary clearance pathways process YK-11 through specific biochemical routes that research shows are different from androgen processing.
