This record applies only to the identified report. It does not establish sterility, human safety, efficacy, or suitability for human or animal use.

How this evidence should be read

UPLC purity separates and measures chromatographic components and can provide higher resolution and faster analysis than conventional HPLC under an appropriate validated method. Mass spectrometry supplies a separate identity result. Quantity reports the measured amount where stated. Endotoxin reports bacterial-endotoxin findings where stated. None of these results establishes sterility, human safety, efficacy, or suitability for human or animal use. Certificate authenticity is checked independently through Horizon Analytical, not by Tuned. Read the full testing explanation.

Questions

TB-500, answered.

Storage, documentation, shipping and research-use terms.

Add to cart
How is the ≥99% purity verified?
This lot (TR-8408241) is independently tested by an independent U.S. laboratory using UPLC for purity and mass spectrometry for identity. The batch-specific Certificate of Analysis is included free and downloadable above.
What's the best way to store TB-500?
Lyophilized TB-500 should be stored according to the product label and applicable institutional laboratory procedures.
How fast does it ship?
Orders placed before 2 PM ET are dispatched the same day (otherwise the next business day). DHL Max standard shipping arrives in 3 business days or better, and FedEx 2-Day Air is available at checkout except for Hawaii. Lyophilized research compounds are stable at room temperature, so cold shipping isn't required. All orders ship discreetly with free shipment protection.
Is this for human use?
No. TB-500 is sold strictly for research, laboratory and educational purposes only. It is not approved for human consumption, veterinary use, or any therapeutic application. By purchasing you confirm you are a qualified researcher and will comply with all applicable laws.
