- 1mL bacteriostatic water
- 5mg/mL
- 4 units (0.04mL)
- 5 units (0.05mL)
- 25 doses
- 20 doses
- Highest concentration. Smallest injection volume but hardest to measure accurately with standard insulin syringes. Risk of dosing error increases.
- 2mL bacteriostatic water
- 2.5mg/mL
- 8 units (0.08mL)
- 10 units (0.1mL)
- Optimal balance for most protocols. Easy to measure, manageable injection volume, standard reconstitution method used by experienced research teams.
- 2.5mL bacteriostatic water
- 2mg/mL
- 12.5 units (0.125mL)
- Slightly lower concentration. Larger injection volume per dose but easier to draw precise measurements. Best for protocols requiring dose adjustments mid-study.
- 3mL bacteriostatic water
- 1.67mg/mL
- 12 units (0.12mL)
- 15 units (0.15mL)
- Lowest concentration. Largest injection volume. Harder to administer subcutaneously without discomfort. Only recommended if syringe precision is a limiting factor.
- The number of doses vial Glow Stack yields stays constant across reconstitution volumes when measured by total peptide content divided by target dose. What changes is the concentration and the physical volume you inject. Most research teams prefer 2mL reconstitution because it produces a concentration that's easy to work with using standard 1mL insulin syringes marked in 100 units. Drawing 10 units to deliver 250mcg is straightforward. Drawing 4 units to deliver the same dose from a higher-concentration solution requires finer motor control and increases the risk of measurement error.
