TB-500 is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Lyophilized (freeze-dried) TB-500 should be stored at -20°C for long-term stability. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 4-6 weeks. Never freeze reconstituted peptides.
How Do You Store TB-500?
Proper storage is critical for maintaining TB-500's potency and safety. As a 43-amino acid peptide, TB-500 is sensitive to heat, light, and moisture — improper storage can render it ineffective or harmful.
How Do You Store Lyophilized TB-500?
Unreconstituted (freeze-dried) TB-500: Store at -20°C (standard freezer) for maximum shelf life of 12-24+ months. Keep the vial sealed and away from moisture.
Room temperature storage is acceptable for short periods (shipping) but degrades potency over weeks. Refrigerator (2-8°C) storage extends this to several months.
How Do You Store Reconstituted TB-500?
After mixing with bacteriostatic water: Store at 2-8°C (standard refrigerator). Use within 4-6 weeks for optimal potency.
Never freeze reconstituted TB-500. Freezing and thawing damages the peptide structure. The bacteriostatic water's benzyl alcohol preservative is what allows the 4-6 week window — sterile water would give you only days.
Keep the vial upright and away from the refrigerator door (temperature fluctuations from opening/closing).
How Do You Know if TB-500 Has Gone Bad?
Reconstituted TB-500 should be clear and colorless. If you see cloudiness, particles, or discoloration — discard it. These indicate bacterial contamination or peptide degradation.
If stored properly, degradation is gradual and may not be visually apparent. This is why the 4-6 week window for reconstituted peptides exists.
Can You Travel With TB-500?
Lyophilized TB-500 can be shipped with cold packs and insulation. For short trips, a small cooler bag with an ice pack maintains adequate temperature.
Reconstituted TB-500 is more temperature-sensitive and should be kept refrigerated during travel if possible.
Bottom Line on TB-500 Storage
Freeze-dried: -20°C, sealed, 12+ months. Reconstituted: 2-8°C, use within 4-6 weeks, never freeze. Source from vendors who ship with proper cold-chain packaging.

Frequently Asked Questions
What is TB-500?
TB-500 (Thymosin Beta-4 Fragment (TB-500)) is a 43-amino acid peptide. Naturally occurring peptide present in virtually all human and animal cells. It is researched for wound healing, tissue repair, inflammation reduction, hair regrowth, cardiac repair, flexibility improvement.
What is the recommended TB-500 dosage?
Common dosages: 2-5 mg (loading), 2 mg (maintenance) administered 2x weekly (loading phase), weekly (maintenance) via subcutaneous or intramuscular injection. Cycle length: 4-6 weeks loading, then ongoing maintenance. Half-life: approximately 2-3 hours. Use our peptide calculator for exact reconstitution math.
What are the side effects of TB-500?
Generally well-tolerated. Temporary lethargy, head rush, or mild headache reported in some users. Minor injection site irritation possible. No organ toxicity documented in research.
Is TB-500 safe?
TB-500 has shown a favorable safety profile in research. Not FDA-approved. Available as a research chemical. Banned by WADA in athletic competition. All research should follow appropriate safety protocols.
