Applications & Usage

Licensed facilities employ this reference standard for:

• Development and validation of highly sensitive LC-MS/MS methods for nandrolone and metabolites
• Forensic identification of unknown injectable preparations via direct side-by-side comparison
• Stability and forced-degradation studies of oil-based steroid esters
• Research into ester cleavage rates and metabolite formation in vitro
• Quality-assurance testing within regulated analytical service providers

All activities must be performed under approved controlled-substance protocols.

Purity & Analytical Testing

Every batch is rigorously characterized using:

• High-Performance Liquid Chromatography (HPLC) with PDA detection
• Gas Chromatography-Mass Spectrometry (GC-MS)
• Nuclear Magnetic Resonance (1H-NMR and 13C-NMR)
• Fourier-Transform Infrared Spectroscopy (FTIR)
• Residual solvent and heavy-metal analysis per ICH Q3 guidelines

Certificate of Analysis guarantees ≥99.0% purity and specifies absence of free nandrolone or decanoic acid.

Safety & Handling Guidelines

Nandrolone Decanoate is a controlled substance (Schedule III in the US and equivalent internationally). Handle only in certified fume hoods while wearing nitrile gloves, safety goggles, and laboratory coat. Store at 15–30 °C, protected from light, in a locked, access-restricted cabinet compliant with national controlled-substance storage requirements. Waste disposal must follow hazardous-chemical and scheduled-substance regulations. Deca Nubol 200mg British Dragon
