Repair & Recovery
TB-500 is a synthetic analogue of a fragment of Thymosin Beta-4, a naturally occurring 43-amino-acid peptide widely studied in tissue-remodelling and actin-sequestration research. Preclinical work has examined its interaction with cell migration, angiogenesis, and inflammatory signalling pathways in animal cell models. For laboratory and research use only.

Researcher FAQ
No. AeroPeptides materials are sold exclusively for in-vitro research and laboratory analytical use. They are not intended to diagnose, treat, cure, or prevent any disease, and are not approved for human or animal administration.
By placing an order, you confirm that you are a qualified researcher and that the material will be used in accordance with all applicable institutional and jurisdictional regulations.
Each lot is independently tested for identity, purity, and mass using HPLC and mass spectrometry. The COA lists the lot number, test date, assay results, and the laboratory that performed the analysis.
Public COA documents are being prepared. In the meantime, you can request a COA for your specific lot and we’ll email it within 1 business day.
Orders ship within 1 business day from the US. Lyophilized peptides are shipped with insulation appropriate to season; short-term ambient excursions during transit do not measurably affect potency.
On receipt, store at −20°C in the sealed vial until reconstitution. See the handling matrix for full storage parameters. Tracked shipping is included; we ship to all US states and most international destinations.
Most peptides are reconstituted with bacteriostatic water (BAC). The volume depends on the target working concentration. Use our Peptide Calculator to compute volume, U-100 insulin syringe units, and doses per vial from peptide mass and target dose.
Once reconstituted, store at 2–8°C and use within 30 days. Protect the vial from light during storage and handling.
Because peptides are temperature-sensitive research materials, we cannot accept returns of opened or unsealed vials. If a shipment arrives damaged or the seal is broken on arrival, contact us within 7 days and we’ll replace or refund.
See our full returns policy for details.
