Product Overview

Testosterone Decanoate (CAS 5721-91-5), also known as Testosterone Caprinate or 17β-Decanoyloxy-androst-4-en-3-one, is a long-acting ester of testosterone. It is a white or off-white crystalline powder with high lipophilicity and stable pharmacological activity. As a key androgen and anabolic steroid, it features slow release, long half-life and stable blood concentration. Widely used in pharmaceutical raw materials, hormone replacement therapy and scientific research. Produced via strict esterification, purification and drying processes, it meets pharmaceutical grade standards with 99%+ purity, low impurities and reliable quality. For legitimate pharmaceutical synthesis, scientific research and medical use only.

Product Features

High Purity: ≥99.0% (HPLC), strictly controlled impurities, meets EP/USP standards.
Long-Acting: Half-life up to 3–4 weeks, stable blood levels with fewer injections.
Good Solubility: Practically insoluble in water; soluble in organic solvents and fatty oils.
Stable Quality: Chemically stable under sealed, low-temperature storage; low moisture absorption.
Factory Direct Supply: Competitive price, sufficient stock, customized packaging, fast delivery.
Strict QC: Full batch testing; COA, MSDS and HPLC spectra available upon request.

Storage & Transportation Instructions

Storage Conditions

Store in a cool, dry, dark and well-ventilated warehouse. Keep containers tightly sealed. Store at 2–8 °C (refrigerated) for long-term storage; avoid freezing. Protect from strong light, heat sources and moisture. Store separately from oxidants, reducing agents and toxic substances. Reseal immediately after opening.

Transportation Requirements

Classified as non-hazardous goods. Use light-proof, moisture-proof sealed packaging (aluminum foil bags, fiber drums). Avoid violent collision, extrusion, strong light and rain. Do not transport with food, feed or toxic substances. Follow IATA/IMDG provisions for international shipping.

Operation Notes

Wear dust mask, chemical-resistant gloves and safety goggles. Operate in a fume hood. Avoid inhalation, skin/eye contact. Rinse with plenty of water for 15 minutes if contact occurs. No eating, drinking or smoking in work area.
