How to Store TB-500 (Thymosin Beta-4): Temperature, Shelf Life & Handling
Storage requirements for TB-500 (Thymosin Beta-4) follow from what the molecule actually is — synthetic fragment of thymosin beta-4. The conditions below reflect that chemistry rather than generic peptide guidance.
In plain English
Freezer for the sealed powder, fridge once mixed, and use within about two to four weeks. Unlike BPC-157, this one needs to be kept out of the light and away from air, because it contains methionine — an amino acid that reacts readily with oxygen.
What TB-500 (Thymosin Beta-4) actually is
TB-500 is a lab-made fragment of Thymosin Beta-4, a protein present in almost every cell in the body and especially concentrated in the fluid around a wound. Research on it centres on cell movement — the internal scaffolding that lets a cell change shape and travel where it is needed.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Storage conditions for TB-500 (Thymosin Beta-4)
Why these conditions, specifically
Storage requirements for TB-500 (Thymosin Beta-4) are set by its degradation chemistry rather than by a general rule for research peptides.
The main route to be aware of: methionine sulfoxide formation — the dominant chemical degradation route, detectable as an earlier-eluting shoulder on RP-HPLC and a +16 Da species on LC-MS.
All 3 degradation routes for TB-500 (Thymosin Beta-4)Freeze–thaw
Aliquot after reconstitution. Repeated cycles risk both concentration effects and progressive oxidation from headspace air introduced at each opening.
What TB-500 (Thymosin Beta-4) is studied for
The defining studied mechanism: binding G-actin and influencing the polymerisation equilibrium that governs cell motility.
Investigated in models where directed cell movement into a tissue defect is the measured endpoint.
Two of the better-populated preclinical literatures for the parent protein.
Studied for effects on inflammatory signalling in tissue-injury models.
