Product Overview

YK11 is a synthetic steroidal selective androgen receptor modulator (SARM) that also functions as a myostatin inhibitor. This unique compound combines the tissue-selective properties of SARMs with additional mechanisms of action, making it a distinctive research tool for studying both androgen receptor modulation and myostatin pathway inhibition.

Molecular Specifications

  • Chemical Name: (17α,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester
  • Molecular Formula: C25H34O6
  • Molecular Weight: 430.53 g/mol
  • CAS Number: 431579-34-9
  • Formulation: Compressed tablets
  • Purity: ≥98% (HPLC verified)

Structural Characteristics

YK11 possesses a steroid backbone similar to dihydrotestosterone (DHT) but with unique modifications including a methoxyethylidene bridge and carboxylic acid methyl ester group. This distinctive structure allows it to function both as a selective androgen receptor modulator and as an inhibitor of myostatin signaling.
