CJC-1295 Draw Technique: Syringe Type Comparison
Insulin syringe (0.5mL) 28–30G 0.01–0.02mL Doses ≤0.5mL, minimises waste Low. Single-use design Optimal for most CJC-1295 protocols; dead space negligible for research dosing Insulin syringe (1mL) 27–29G 0.02–0.03mL Doses 0.5–1.0mL Preferred for higher-volume
This comparison does not assign a generated winner or score.
- Insulin syringe (0.5mL)
- 28–30G
- 0.01–0.02mL
- Doses ≤0.5mL, minimises waste
- Low. Single-use design
- Optimal for most CJC-1295 protocols; dead space negligible for research dosing
- Insulin syringe (1mL)
- 27–29G
- 0.02–0.03mL
- Doses 0.5–1.0mL
- Preferred for higher-volume draws; slightly larger dead space acceptable
- Luer-lock syringe + separate needle
- 25–27G
- 0.05–0.10mL
- Multi-vial sampling, larger volumes
- Moderate. Connection point adds contamination risk
- Avoid for single-vial peptide use; dead space wastes expensive compound
- Prefilled syringe (some research kits)
- Fixed 27G
- 0.00mL
- Pre-measured doses only
- Very low. Sealed until use
- Eliminates user error but limits dosing flexibility
