Testosterone Cypionate 100 mg/mL Vial Sizes

Testosterone cypionate at 100 mg/mL concentration is available in 1 mL and 10 mL vials 1, 2.

Available Vial Sizes

According to FDA labeling, testosterone cypionate 100 mg/mL is supplied in:

  • 1 mL vials (NDC 54868-3618-1)
  • 10 mL vials (NDC 54868-3618-0) 2

Clinical Context

The 100 mg/mL concentration is one of two standard concentrations for testosterone cypionate injections, with the other being 200 mg/mL 1. Both concentrations are used for intramuscular testosterone replacement therapy with typical dosing of 100-200 mg every 2 weeks or 50 mg weekly 1.

Storage Requirements

Vials should be stored at 20° to 25°C (68° to 77°F) and protected from light 2.

Practical Considerations

  • The 10 mL vial is more cost-effective for patients on chronic therapy requiring multiple doses
  • The 1 mL vial may be preferred for single-dose administration or when prescribing smaller volumes
  • Both vial sizes contain benzyl alcohol as a preservative (9.45 mg/mL) 2
