YK-11 is a synthetic steroidal selective androgen receptor modulator (SARM) — a 19-nor DHT-derived analog with a spiro-dioxolane modification at C-17, structurally distinct from non-steroidal SARMs. It is not FDA-approved for any human use and is prohibited in competitive sport; anti-doping laboratories actively screen for YK-11 metabolites. No human safety, tolerability, or efficacy trials exist; the only published human study administered deuterated YK-11 solely to identify urinary metabolites for doping-control method development.

How are YK-11 prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
No human safety, tolerability, or efficacy trials exist for YK-11. The only published human study administered six-fold deuterated YK-11 to volunteers solely to identify urinary metabolites for anti-doping method development; no intact parent compound was recovered in urine, and 14 metabolites (unconjugated, glucuronidated, sulfated) were characterized. In vitro (mouse C2C12 myoblasts), YK-11 (1–500 nM) increased myosin heavy chain and myogenic regulatory factor expression more strongly than equimolar DHT and uniquely induced follistatin, a pathway necessary for its pro-differentiation effect. In vivo (mouse model of gram-negative bacterial sepsis), YK-11 reduced circulating pro-inflammatory cytokines and organ-damage markers, decreased sepsis mortality, and was associated with protection against sepsis-induced muscle wasting.
