🧪 What Is Trenbolone Hexahydrobenzylcarbonate?

Trenbolone hexahydrobenzylcarbonate (also known as Parabolan, Hexabolan) is a long-acting trenbolone ester of the 19-nor testosterone family.
It functions as a depot prodrug: after intramuscular injection, the bulky hexahydrobenzylcarbonate ester releases free trenbolone over an extended period.

Originally marketed in France as Parabolan (1980–1997), it no longer has any approved medical use. Today it appears exclusively as a research and analytical compound.

🔬 Mechanism of Action

1. Androgen Receptor Activation

Once released from the ester, trenbolone binds strongly to the androgen receptor (AR), producing:

• High anabolic signalling
• Enhanced nitrogen retention
• Increased protein synthesis
• Stimulation of erythropoiesis

2. Non-aromatising profile

Trenbolone does not aromatise to estradiol.

3. Progestogenic activity

Trenbolone analogues display measurable progestogenic effects, contributing to HPG-axis suppression and potential endocrine interactions.

4. Depot Kinetics

The hexahydrobenzylcarbonate ester gives a long release duration, with an effective half-life of ~8–11 days.

📚 Research Applications

• Androgen receptor binding and signalling studies
• Comparative anabolic vs androgenic tissue-selectivity models
• Structure–activity analysis of trenbolone esters
• Reference material for LC-MS/MS / GC-MS steroid profiling
• Anti-doping method development for trenbolone metabolites
• Pharmacokinetic modelling of long-acting androgen esters

📈 Potential Research-Level Observations

• Powerful anabolic response relative to dose
• Low water-retention profile compared with aromatising AAS
• Strong recomposition markers in pre-clinical models
• Distinct metabolite profile ideal for analytical method calibration

Note: These points reflect biochemical properties, not performance claims.
