TB-500 Storage: Lyophilized vs Reconstituted Comparison
Before reconstituting TB-500, understand the trade-offs between lyophilized and aqueous storage: Lyophilized powder −20°C 24–36 months <1% per year Minimal (sealed vial) Long-term inventory storage before use Optimal for storage. No time pressure, maximum stab

- Before reconstituting TB-500, understand the trade-offs between lyophilized and aqueous storage:
- Lyophilized powder
- −20°C
- 24–36 months
- <1% per year
- Minimal (sealed vial)
- Long-term inventory storage before use
- Optimal for storage. No time pressure, maximum stability, lowest risk
- Reconstituted solution
- 2–8°C
- 28 days maximum
- ~5% per month
- Moderate (bacterial growth after 28 days)
- Active research protocols requiring daily dosing
- Use-it-or-lose-it window. Plan dosing schedule before reconstitution
- Room temperature (reconstituted)
- 20–25°C
- 24–48 hours
- ~15% per month equivalent
- High (rapid bacterial proliferation)
- Emergency short-term holding only
- Avoid entirely. Degradation accelerates, contamination risk spikes
- The table makes the strategy clear: store TB-500 long term in lyophilized form and reconstitute only when you're ready to begin a dosing protocol. Reconstitution is irreversible. Once water contacts the peptide, the 28-day countdown begins whether you use the product or not.
