What is Trenbolone Hexahydrobenzylcarbonate?
Trenbolone Hexahydrobenzylcarbonate (Parabolan — long-acting 19-nor anabolic-androgenic steroid (injectable)) is the cyclohexylmethylcarbonate ester of trenbolone — C₂₆H₃₄O₄, MW 410.5. The only trenbolone ester approved for human clinical use (French Parabolan, 1980–1997). Longest-acting trenbolone ester (peak ~4–7 days, active ~14 days). ~5× greater AR affinity than testosterone. Does not aromatise. Activates progesterone receptor (PR).

Frequently Asked Questions
How do I reconstitute this peptide?
QSC Trenbolone esters are supplied as ready-to-use oil-based injectable solutions — no reconstitution required. Warm the vial in your hand before drawing to reduce viscosity of the oil.
How should this peptide be stored?
Store at room temperature (15–25°C), away from direct sunlight. Oil-based Trenbolone solutions are stable at room temperature for 2–3 years. The hexahydrobenzylcarbonate ester (Tren Hex) has particularly long storage stability.
What purity is this QSC compound and how is it verified?
QSC Trenbolone esters are ≥99% HPLC pure with MS-confirmed identity on every batch. COA is published on the product page and verifiable at verify.janoshik.com.
