Certificate Of Analysis


Frequently Asked Questions

What purity standard does TB-500 meet?
Every batch exceeds 99% purity and is independently verified by HPLC and LC-MS at an ISO 17025 accredited laboratory. Identity and active mass per vial are confirmed before release.
How should this vial be stored?
Lyophilized powder is stored sealed at -20C or below, protected from light, and is stable at ambient temperature in transit. Once reconstituted with sterile research-grade solvent, store at 2-8C and avoid repeated freeze-thaw cycles.
Where can I find the certificate of analysis for this lot?
Every product links to its COA from the product page, and the full library is at the COA Reports page. Each certificate lists test methods, acceptance criteria, and results for that batch.
What is the difference between the vial, capsule, and spray formats?
Vials are lyophilized powder for laboratories preparing their own concentrations. Capsules provide a fixed pre-measured amount per unit. Liquid sprays are supplied pre-mixed at a consistent concentration per actuation.
What does research use only mean for this order?
All Pure Bio Labs products are distributed strictly for laboratory research and in vitro experimentation. They are not approved for human or veterinary use and are not intended to diagnose, treat, cure, or prevent any condition.
