Trenbolone Enanthate
Long-acting trenbolone compound providing sustained serum levels over extended intervals.
Trenbolone Enanthate
Trenbolone Enanthate is a sterile oil-based injectable preparation of trenbolone esterified with enanthic acid, presented at 200 milligrams per millilitre in a 10 mL multiple dose vial. It delivers the pharmacology of trenbolone over a considerably longer release phase than the acetate ester.
Structural Profile
The active moiety is trenbolone, 17-beta-hydroxyestra-4,9,11-trien-3-one, a 19-nortestosterone derivative bearing additional double bonds at positions 9 and 11. Esterified with enanthic acid at the 17-beta hydroxyl, the molecular formula is C25H34O3 with a molar mass of 382.54 g/mol. The triene configuration renders the molecule resistant to both aromatase and 5-alpha reductase.
Esterification and Release
The seven-carbon enanthate chain is markedly more lipophilic than acetate and extends depot residence considerably. Release into systemic circulation is gradual, producing a flatter serum curve and permitting a longer interval between administrations.
Pharmacokinetic Profile
The elimination half-life is approximately 5.5 days. Serum concentrations rise over the first days following administration and decline slowly thereafter. The urinary detection window for trenbolone metabolites extends to approximately 5 months.
Mechanism of Action
Trenbolone binds the cytoplasmic androgen receptor with an affinity several times that of testosterone; the activated complex engages androgen response elements and upregulates transcription of genes controlling structural protein synthesis and nitrogen retention. No aromatisation to oestradiol occurs, as the 4,9,11-triene structure is not a substrate for the enzyme. Affinity for the glucocorticoid receptor contributes an additional anti-catabolic component to the pharmacological profile.
Manufacturing and Sterility
Each production lot is released against the complete pharmaceutical testing protocol: HPLC identity confirmation and purity analysis with a specification of not less than 98 percent, verification of concentration against label claim within 5 percent, sterility testing in accordance with USP <71>, bacterial endotoxin quantification by LAL assay below 0.25 EU/mL, and particulate matter inspection in accordance with USP <788>. A Certificate of Analysis is issued for every lot.
Quality Assurance
Every batch of Trenbolone Enanthate produced by Biomedica undergoes the complete pharmaceutical release testing protocol before distribution. This includes HPLC compound identity confirmation and purity analysis (specification: ≥98%), concentration verification (specification: ±5% of label claim), sterility testing per USP <71>, bacterial endotoxin quantification by LAL assay (specification: <0.25 EU/mL), and particulate matter inspection per USP <788>. A Certificate of Analysis is issued for every production lot.
Authentication
