Trenbolone Hexahydrobenzylcarbonate, commonly and informally abbreviated as Tren Hex or Trenbolone Hex. It is a longer acting esterified variant of the anabolic steroid Trenbolone, which is the most popular in the form of Trenbolone Acetate (a much faster acting esterified variant of Trenbolone). The Hexahydrobenzylcarbonate ester extends Trenbolone’s half-life to the extent of approximately 14 days rather than 3 days, which is the half-life of Trenbolone Acetate.
