Parabolin 76.5 mg — Clinical & Pharmaceutical Reference Guide

Introduction

Parabolin 76.5 mg (trenbolone hexahydrobenzylcarbonate) from Alpha Pharma is the authentic, modern successor to the legendary Parabolan® and remains the most analytically trusted long-acting trenbolone reference standard worldwide. The hexahydrobenzylcarbonate (“hex”) ester provides an extended half-life of approximately 14 days, making it the ideal model compound for studying prolonged 19-nor steroid exposure, late-phase metabolites, and extended detection windows in urine, hair, and blood. With original Alpha Pharma holograms, purity consistently ≥ 99.8 %, and exact 76.5 mg/ml concentration, Parabolin is the material of choice in more than 45 WADA- and FEI-accredited laboratories. This guide provides comprehensive Parabolin 76.5 mg information strictly within the legal framework of non-consumptive scientific use.
