About this compound
Is this specific batch tested?
Yes the certificate above is for the exact lot currently shipping, matched by batch number. You can verify it independently using the lookup tool or the QR code on the vial.
How should I store this?
Keep the lyophilized vial in a freezer, away from light, until you’re ready to use it. Once reconstituted, store refrigerated and reference the COA for batch-specific stability notes.
How do I reconstitute this for my protocol?
Add your diluent slowly down the inside wall of the vial, then swirl gently until dissolved — avoid shaking. Exact diluent volume depends on your protocol and the strength you ordered (5mg, 10mg, or 15mg).
How fast will it ship?
Same-day dispatch if ordered before the daily cutoff, 2–3 days tracked delivery from our domestic warehouses in the US, EU, or Australia.
What if I am not satisfied?
98%+ purity guaranteed or refunded. Send us an independent test result and we’ll make it right.
What Is TB-500?
TB-500 is a synthetic peptide based on thymosin beta-4 (Tβ4), a protein found in almost every human cell type. Thymosin beta-4 is best known as a regulator of actin, the structural protein that lets cells change shape and move, and that role makes it central to studies of cell migration.
In cell-culture and animal-model studies, thymosin beta-4 and its derivatives have been examined for cellular migration, anti-inflammatory signalling, and tissue-remodelling pathways. Nation Peptides supplies TB-500 strictly for in vitro and laboratory use and makes no medical or therapeutic claims about it.

Buy TB 500 With a Certificate You Can Check
Anyone comparing a TB-500 peptide for sale should look for lot-specific evidence of purity and identity, which matters more for a larger peptide. These are the checks a lab should expect, and what this page provides for batch 600001.
- A named laboratory and a test date. Tested February 18, 2026 by Freedom Diagnostics.
- A purity figure from HPLC. This batch reports 99.86%.
- An identity result. Mass spectrometry confirms the compound, and identity is listed as passed.
- A traceable lot. Match the batch number to the vial label, use the lookup tool, or scan the QR code on the vial.
Each order is matched to a verified batch and certificate before packing.
TB-500 Alongside Other Compounds
TB-500 is most often studied with BPC-157, and the catalogue offers the pair in several formats. The BPC 157 & TB 500 puts both in one 10/10mg vial, and the Wolverine peptide stack is a pre-built stack of the same two compounds. The Glow Blend adds GHK-Cu, and the Klow Blend adds KPV as well.
If you prefer to set your own ratio, you can buy BPC 157 as a separate 10mg vial. TB-500 ships as lyophilized powder, so many labs also buy bacteriostatic water in a 10ml vial with the order.
