Trenbolone Hexahydrobenzylcarbonate (Parabolan): Complete Overview
Trenbolone Hexahydrobenzylcarbonate, commonly known as Parabolan, is a long-acting ester of trenbolone that has gained attention in discussions around anabolic compounds. Originally developed for veterinary purposes, it is often referenced in fitness and bodybuilding circles for its potent anabolic properties.
This guide provides an educational overview of Trenbolone Hexahydrobenzylcarbonate, including its characteristics, potential effects, risks, and legal considerations.
What Is Trenbolone Hexahydrobenzylcarbonate?
Trenbolone Hexahydrobenzylcarbonate is an esterified form of trenbolone, designed to release slowly into the bloodstream. The hexahydrobenzylcarbonate ester extends the compound’s activity, resulting in a longer half-life compared to shorter trenbolone variants.
It was historically marketed under the brand name Parabolan and is known for its strong binding affinity to androgen receptors.
Key Characteristics
-
Compound Type: Anabolic–androgenic steroid
-
Ester: Hexahydrobenzylcarbonate (long-acting)
-
Release Profile: Slow and sustained
-

In educational and scientific discussions, Trenbolone Hexahydrobenzylcarbonate is often associated with:
-
Increased nitrogen retention
-
Enhanced protein synthesis
-
Improved feed efficiency (in veterinary contexts)
-
Strong anabolic activity relative to testosterone
It does not aromatize into estrogen, which differentiates it from many other anabolic compounds.
