Testosterone Cypionate 250 mg/ml is a long-ester testosterone compound commonly used in research exploring androgen receptor activity, hormone kinetics, and ester-release modeling. Its extended half-life allows for slower, steady release following administration, making it a useful reference in pharmacokinetic and formulation studies.

Product Composition

• Active compound: Testosterone Cypionate — 250 mg/ml

  • Carrier Oil: Ethyl Oleate — low-viscosity ester solvent

Research Application

• Investigating ester-cleavage rates and hormone-release curves
• Modeling androgen receptor binding and bioavailability patterns
• Studying oil-based injectable pharmacokinetics in controlled settings

Handling & Technical Notes

• Viscosity: Ethyl Oleate provides smooth, low-resistance injection characteristics
• Storage: Maintain in a cool, dry place (< 25 °C), protected from light

• Recommended study volume: Draw using sterile 18–21 G needle; inject through 23–25 G for low-resistance flow

Box Contents

• 1 × 10 ml vial of Testosterone Cypionate 250 mg/ml

About Ethyl Oleate Carrier

Ethyl Oleate (EO) is used for its ability to maintain compounds in stable suspension while producing a thin, low-viscosity solution. This improves measurement precision and reduces mechanical resistance when drawn or administered in laboratory settings.
