- This table demonstrates how different reconstitution volumes affect concentration, injection volume, and syringe measurement for common TB-500 research doses.
- 5mg
- 1mL
- 5mg/mL
- 0.4mL
- 40 units
- High concentration—small injection volumes ideal for rodent models or high-frequency dosing, but requires precise syringe measurement
- 2mL
- 2.5mg/mL
- 0.8mL
- 80 units
- Balanced concentration—easier to measure accurately with standard 1mL insulin syringes, suitable for most subcutaneous protocols
- 2.5mL
- 2mg/mL
- 100 units
- Lower concentration—maximises measurement precision and reduces calculation errors, but larger injection volumes may not suit all applications
- 10mg
- High concentration from larger vial—extends usable doses per vial but demands careful syringe technique to avoid measurement drift
- 3mL
- 3.33mg/mL
- 0.6mL
- 1.5mL
- 60 units
- Moderate concentration—good middle ground for protocols requiring multiple doses per vial without excessive injection volume per administration
- The table makes clear that there is no universal 'correct' reconstitution volume—only the volume that aligns with your syringe type, injection site constraints, and dosing frequency. Researchers using 0.3mL or 0.5mL syringes benefit from higher concentrations that keep injection volumes below 0.5mL. Researchers prioritising measurement ease and error reduction benefit from lower concentrations that spread the dose across a larger, easier-to-read syringe range.
