Not for clinical, diagnostic, or consumptive applications.

Product Overview

YK-11 Powder, commonly referenced under the research designation Myostine, is a structurally unique compound that occupies a distinctive position within the selective androgen receptor modulator (SARM) research category. Unlike conventional SARMs, YK-11 is also investigated for its potential interactions with myostatin pathways, making it a subject of considerable scientific interest in skeletal muscle biology, cellular signalling, and endocrinology research. EU Chems Lab supplies this compound directly from verified European stock, ensuring rapid availability and consistent batch quality for research institutions across the EU and beyond.

Chemical Identity & Classification

YK-11 is chemically identified as (17α,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester, with the CAS registry number 1370003-76-1. It is classified as a steroidal SARM and is structurally derived from 5α-dihydrotestosterone (DHT), distinguishing it from the more commonly studied non-steroidal SARMs. Its dual mechanism of action — partial androgen receptor agonism combined with putative myostatin inhibition — makes it a highly relevant compound for advanced molecular biology and receptor pharmacology studies.

Purity & Analytical Verification

Every batch of YK-11 Powder (Myostine) supplied by EU Chems Lab is analytically verified to confirm a minimum purity of ≥98%. Verification is conducted using industry-standard analytical methodologies including High-Performance Liquid Chromatography (HPLC) and Nuclear Magnetic Resonance (NMR) spectroscopy, ensuring both chemical identity and quantitative purity are confirmed prior to release. Certificates of Analysis (CoA) are available upon request, providing full transparency for research documentation and institutional compliance requirements.

Quality Control & Batch Integrity

EU Chems Lab operates under stringent quality control protocols to guarantee that every unit dispatched meets the declared specification. Batch-to-batch consistency is maintained through systematic in-process testing, ensuring that researchers receive a chemically uniform reference material across repeated orders. This level of reproducibility is essential for longitudinal study designs and multi-series experimental programmes where compound variability would compromise data integrity. Each batch is assigned a unique lot identifier, traceable through our internal QC documentation chain.

Safety, Handling & Laboratory Precautions

As with all research chemicals, appropriate laboratory safety protocols must be observed when handling YK-11 Powder. Personnel should utilise suitable personal protective equipment (PPE) including nitrile gloves, laboratory coat, and eye protection. Handling should be performed in a well-ventilated environment or under a fume hood where dust generation is possible. This compound is strictly intended for use by trained laboratory professionals in controlled research settings only. Refer to the relevant Safety Data Sheet (SDS) prior to handling.

Packaging, Labeling & Storage

YK-11 Powder is packaged in chemically inert, sealed containers appropriate for the preservation of fine powder compounds. All packaging is clearly labelled with product name, CAS number, lot number, purity grade, and the mandatory research-use designation. Storage at 2–8°C in a dry, dark environment is strongly recommended to maintain compound stability and purity over the declared shelf life. Packaging is designed to withstand standard international shipping conditions while preserving sample integrity upon arrival.
