Trenbolone Hexahydrobenzylcarbonate (Parabolan Depot)
Trenbolone hexahydrobenzylcarbonate—historically recognized under the iconic clinical trade name Parabolan—is a premier long-acting injectable 19-nor anabolic-androgenic steroid engineered for significant muscle hardness, dense contractile mass, and unmatched strength progression. Featuring a slow-cleaving hexahydrobenzylcarbonate ester chain, this compound provides sustained, stable physiological activity, eliminating the need for frequent daily injections.
Our catalog offers authentic injectable Parabolan solutions manufactured in strict compliance with pharmaceutical-grade standards, guaranteeing smooth oil carriers, precise active substance content, and certified purity.
Mechanism of Action & Pharmacological Profile
As a modified derivative of 19-nortestosterone (nandrolone), trenbolone exhibits double bonds at carbon positions 9 and 11. This specific configuration substantially amplifies its binding affinity for both androgen and progesterone receptors while preventing metabolic conversion to estrogen.
The extended hexahydrobenzylcarbonate (cyclohexylmethylcarbonate) ester attached to the 17-beta hydroxyl group yields clear biological properties:
- Extended Release Dynamics: The large molecular weight of the ester facilitates slow enzymatic cleavage from the intramuscular injection site, providing an active half-life of roughly 10 to 14 days and consistent serum hormone concentrations.
- Zero Estrogenic Conversion: Completely immune to the aromatase enzyme, preventing estrogen-related subcutaneous water retention, puffy vascularity, and excess fluid accumulation.
- Exceptional Anabolic Index: Demonstrates an anabolic and androgenic rating five times higher than baseline testosterone, driving substantial protein synthesis, nutrient partitioning, and red blood cell production.
Technical Specifications & Administration Protocols
Injectable Parabolan is formulated in sterile oil-based preparations, presented in single-dose glass ampoules or multi-dose vials. Its sustained release profile enables flexible administration schedules across both competitive cutting and lean bulking protocols.

Primary Applications in High-Performance Phases
- Stage Conditioning & Vascularity: Widely regarded as an ultimate compound for contest preparation, promoting granular muscle separation, paper-thin skin appearance, and dense cosmetic vascularity.
- Nutrient Partitioning Under Deficits: Uniquely redirects nutritional intake toward muscle tissue preservation and growth while simultaneously accelerating fatty acid oxidation.
- Significant Kinetic Strength: Drives central nervous recruitment and muscular contractile tension without adding unwanted water weight, allowing continuous progressive overload.
Ancillary Care, Prolactin & Biomarker Management
Due to its pronounced potency and progestogenic activity, safe administration of trenbolone hexahydrobenzylcarbonate requires disciplined cycle management and targeted support:
- Prolactin Management: Trenbolone possesses high affinity for the progesterone receptor, which can elevate circulating prolactin. Keeping a dopamine agonist (such as Cabergoline) available based on routine blood panels helps avoid prolactin-mediated side effects.
- Cardiovascular & Blood Pressure Care: Trenbolone can influence cardiovascular markers, raising arterial resistance and altering lipid profiles. Regular aerobic conditioning, monitoring of systolic/diastolic values, and daily supplementation with omega-3 fatty acids and citrus bergamot are strongly advised.
- Post Cycle Recovery (PCT): Trenbolone induces profound suppression of the hypothalamic-pituitary-gonadal (HPG) axis. A structured recovery phase using SERMs (such as Clomiphene and Tamoxifen) must be initiated following the complete clearance of the long-acting hexahydrobenzylcarbonate ester.
Batch Verification & Order Fulfillment
