The recommended syringe size for testosterone injections depends on the patient's age.
According to the provided reference, here's a breakdown:
| Patient Group | Syringe Size | Needle Gauge & Length | Injection Site |
|---|---|---|---|
| Infants | 1- or 3-mL Luer-Lock | 25-G ⅝″ | Vastus Lateralis |
| Older Patients | 1- or 3-mL Luer-Lock | 23-G 1″ | Vastus Lateralis or Gluteus (for larger patients) |
Key Considerations:
- Syringe Volume: Both 1-mL and 3-mL Luer-Lock syringes are suitable. The choice may depend on the volume of testosterone being injected. For smaller doses, a 1-mL syringe might offer more precise measurement.
- Needle Gauge and Length: A 25-G ⅝″ needle is recommended for infants, while a 23-G 1″ needle is recommended for older patients.
- Injection Site: The vastus lateralis (thigh) is the preferred injection site. The gluteus (buttocks) can be used for larger, older patients.
