Buy Methasteron Supplier & Suppliers

Global Market Equilibrium

Methasteron (widely known under the trade identifier Superdrol and CAS Registry No. 3381-88-2) holds a distinct position within the portfolio of synthetic C17-alkylated steroidal derivatives. Commercial demand across non-clinical laboratories focuses on binding-affinity assay references, chromatographic calibrants, and chemical pathway mapping.

• IUPAC: 17β-hydroxy-2α,17α-dimethyl-5α-androstan-3-one
• Formula Weight: 318.49 g/mol
• Physical State: Fine white crystalline powder

Regulatory & Compliance Context

The global trade of Methasteron is strictly framed by international monitoring. In jurisdictions such as the United States (DEA Schedule III classification) and under WADA testing frameworks, distribution is restricted exclusively to authorized researchers, certified laboratories, and compliant academic institutions holding legal clearance.

• Controlled precursor surveillance
• Mandatory end-user declarations (EUD)
• Traceable batch release documentation

Analytical Release Criteria

Reliable suppliers implement orthogonal chromatography regimens. Given the high anabolic-to-androgenic structural profile and metabolic susceptibility of the 2α-methyl branch, purity verification requires Gas Chromatography-Mass Spectrometry (GC-MS) coupled with High-Performance Liquid Chromatography (HPLC).

• Assay purity: ≥ 98.5% (HPLC normalization)
• Loss on drying (LOD): ≤ 0.5%
• Heavy metal threshold: < 10 ppm

Reference Material for Anti-Doping Testing

The prominent commercial application of verified Methasteron raw material is the formulation of analytical calibration matrices. Anti-doping laboratories accredited by international standards bodies continuously require ultra-pure reference powders to update LC-MS/MS spectral libraries for human urinary and equine metabolite tracing.

Academic AR Pathway Investigations

Researchers investigating Androgen Receptor (AR) non-genomic transcription frequently utilize Methasteron derivatives. Because it lacks aromatization potential (inability to convert into estrogenic metabolites) while exhibiting potent binding affinity, it serves as a baseline tool for characterizing structural receptor docking.

Custom Precursor & Synthesis Inquiries

Global pharmaceutical entities focused on hepatic-protective agent research leverage custom-synthesized lots to evaluate how C17 alkyl modifications interact with hepatocyte phase I/II clearance enzymes (CYP3A4, glucuronidation), mapping the toxicological liabilities of alkylated steroidal classes.
