Testorapid 100 mg — Clinical & Pharmaceutical Reference Guide

Introduction

Testorapid 100 mg (testosterone propionate) from Alpha Pharma is the most analytically trusted short-acting testosterone ester reference standard worldwide. The propionate ester confers a half-life of only 0.8–1.5 days, making it the ideal model compound for studying rapid-onset androgen effects, early-phase ester hydrolysis, and short detection windows in biological matrices. With original Alpha Pharma holograms, purity consistently ≥ 99.8 %, and exceptional concentration precision, Testorapid is the material of choice in over 45 WADA-accredited laboratories and numerous ISO 17025 forensic facilities. This guide provides detailed Testorapid 100 mg information strictly within the legal framework of non-consumptive scientific use.

Purity & Analytical Testing

Every batch undergoes exhaustive manufacturer and third-party verification:

• High-Performance Liquid Chromatography (HPLC-DAD) – purity ≥ 99.8 %, related substances ≤ 0.2 %
• Gas Chromatography-Mass Spectrometry (GC-MS) – molecular ion m/z 344, characteristic fragments 272, 255
• Proton & Carbon NMR – full confirmation of propionate side-chain and Δ4-3-keto system
• Fourier-Transform Infrared Spectroscopy – sharp carbonyl stretches at 1738 cm⁻¹ (propionate) and 1665 cm⁻¹ (conjugated ketone)

Full spectra and chromatograms are archived and provided to qualified institutions.
