Direct factory-cleared lots ready for immediate global logistics dispatch. Every batch verified via analytical HPLC, NMR, and high-resolution mass spectrometry.
A definitive briefing for pharmaceutical procurement officers, regulatory compliance auditors, and licensed formulation contract manufacturers seeking authenticated active pharmaceutical ingredients (APIs).
Nandrolone Decanoate (17β-hydroxyestr-4-en-3-one 17-decanoate, CAS: 360-70-3, C28H44O3, MW: 428.65 g/mol) is a synthetic derivative of 19-nortestosterone. The esterification of the 17-beta-hydroxyl group with decanoic acid imparts high lipophilicity, extending intramuscular sustained-release biological half-lives up to 15 days in oil carriers.
Synthesized strictly to USP / Ph. Eur. / BP standards, our bulk raw API presents as a white to creamy-white crystalline powder with a defined melting range of 33°C to 37°C. It exhibits specific optical rotation between +32° and +36° (in dioxane), maintaining less than 0.5% total related substances and zero unreacted free nandrolone residues.
Due to its prolonged carbon ester chain, the molecule displays rapid dissolution in organic vehicle systems, including benzyl alcohol, benzyl benzoate, ethyl oleate, sesame oil, and medium-chain triglycerides (MCT). This enables consistent preparation of 100mg/mL to 300mg/mL parenteral injectables without premature precipitate crystallization.
Procuring anabolic-androgenic steroidal APIs demands strict navigation across international narcotics conventions, national controlled substance quotas, and tightening environmental compliance standards across major pharmaceutical manufacturing hubs.
Global demand for authenticated Nandrolone Decanoate remains anchored in oncology wasting syndrome protocols, chronic renal insufficiency anemia formulations, and refractory postmenopausal osteoporosis treatments. Secondary clinical research into micro-dosed androgen replacement therapy (TRT adjuncts) and joint connective tissue repair has expanded the demand for high-batch consistency API raw materials across emerging compounding pharmacies.
Modern synthetic pathways have shifted from reliance on scarce wild diosgenin to industrialized phytosterol fermentation routes producing 4-androstenedione (4-AD) and 19-nor-4-androstenedione intermediates. Facilities with direct upstream bio-fermentation integration mitigate global price volatility, guaranteeing non-disrupted bulk material deliveries during seasonal precursor shortages.
International enterprise shipping hinges upon transparent customs categorization under Harmonized Tariff System (HTS) Code 2937.28.00 (Steroid hormones, their derivatives and structural analogues). Factory-level documentation packets eliminate customs seizure risks through full End-User Declaration (EUD) verification, legitimate import permits, and authenticated chain-of-custody validation.
Every batch produced in our ISO-classified cleanrooms is benchmarked against rigorous compendial pharmacopeial parameters (USP43/NF38 and Ph. Eur. 10.0), guaranteeing zero heavy metals and sub-ppm residual solvent levels.

Nandrolone Decanoate has a low melting point between 33°C and 37°C. Ambient temperatures in warm climates can cause partial agglomeration or liquefaction if not properly packaged. We utilize vacuum-sealed, multi-barrier foil packaging with desiccant packs within insulated shipping containers, maintaining stability below 25°C to preserve crystal integrity.
