DROSTANOLONE PROPIONATE 100mg MACTROPIN — Clinical & Pharmaceutical Reference Guide

Introduction

Drostanolone Propionate 100 mg/mL from Mactropin is a high-purity, short-acting anabolic-androgenic steroid widely regarded as one of the most consistent reference standards in modern analytical chemistry. The fast-releasing propionate ester combined with the 2α-methylated DHT backbone provides excellent chromatographic resolution, rapid clearance, and highly reproducible mass-spectral fragmentation, making it indispensable for high-sensitivity steroid screening and method-validation studies. Manufactured under strict pharmaceutical-grade protocols and independently verified to exceed 99.5% purity, this material guarantees the precision and legal traceability required in regulated laboratory environments.

Key Features & Scientific Relevance

• ≥99.5% purity confirmed by independent ISO/IEC 17025 laboratories
• Short propionate ester (analytical half-life ≈ 1.5–2 days)
• Exceptional long-term stability in oil carrier (>36 months)
• Primary reference standard in WADA, IOC, and national anti-doping programs
• Full compliance with DEA Schedule III, EMA, and global controlled-substance regulations

The clinical profile of DROSTANOLONE PROPIONATE 100mg MACTROPIN makes it a cornerstone compound for LC-MS/MS and GC-MS steroid profiling worldwide.
