Trenbolone Hexahydrobenzylcarbonate — Parabolan 100 by Dragon Pharma

Parabolan 100 is Dragon Pharma's formulation of Trenbolone Hexahydrobenzylcarbonate at 100mg/ml — the longest-acting injectable Trenbolone ester, with an approximate 14-day half-life allowing weekly injections. Parabolan holds a unique distinction among all Trenbolone products: it is the only Trenbolone compound that was ever approved for human pharmaceutical use, manufactured by Negma Laboratoires (France) under the trade name "Parabolan" from the 1980s until its discontinuation in 1997.

Parabolan's Pharmaceutical History — The Only Human-Approved Trenbolone

This distinction separates Parabolan from every other Trenbolone product and is a genuine information gap in competitor content:

• Trenbolone Acetate was originally developed as a veterinary product — used in cattle implants (Finaplix/Revalor) for livestock muscle development, never intended or approved for human use
• Trenbolone Hexahydrobenzylcarbonate was developed by Negma Laboratoires in France and approved as a human anabolic prescription medication — "Parabolan" — indicated for conditions including cachexia, osteoporosis and androgen deficiency
• Negma manufactured Parabolan in 76.5mg/1.5ml ampules (equivalent to approximately 50mg of pure Trenbolone base) and marketed it in France from approximately 1980 until 1997
• In 1997, Negma discontinued Parabolan commercially — not due to safety issues but due to commercial decisions, regulatory environment changes and liability concerns. No Trenbolone product has received human pharmaceutical approval since
• This brief pharmaceutical history means Parabolan is the only Trenbolone ester for which some structured human pharmacokinetic and clinical data exists from legitimate pharmaceutical production

The Hexahydrobenzylcarbonate Ester — What Makes It Different

The Hexahydrobenzylcarbonate ester is unique in the Trenbolone family:

• It is a cyclohexylmethyl carbonate — structurally more complex than the simple fatty acid esters used in Trenbolone Acetate and Enanthate
• This structure produces an approximate 14-day half-life — longer than Enanthate (~7-10 days) and dramatically longer than Acetate (~2-3 days)
• The practical implication: once-weekly injection maintains stable Trenbolone blood levels — more convenient than Enanthate (twice-weekly) and significantly more convenient than Acetate (EOD)
• The longer half-life also means Parabolan takes longer to reach steady-state blood levels than shorter esters — and takes longer to clear if the cycle is stopped, similar to Trenbolone Enanthate but extended further

Parabolan vs All Trenbolone Formats

Effects and Benefits

• The same compound-level effects as all Trenbolone products — lean mass, fat loss, strength, hardness, vascularity, no aromatisation
• Once-weekly injection — the most convenient injectable Trenbolone injection schedule
• Stable blood levels maintained with weekly injections due to the long ~14-day half-life
• The longest-acting Trenbolone ester for users wanting minimum injection frequency

Dosage and Administration

Parabolan is not recommended for first Trenbolone cycles — its long half-life means side effects persist for 3-4 weeks after stopping, significantly longer than Acetate. It suits experienced users who have established their Trenbolone tolerance and want the convenience of once-weekly injection. PCT begins 3-4 weeks after the last Parabolan injection.
