TB-500 Spray

TB-500 Spray is supplied as a pre-dissolved, sterile-filtered solution in amber glass bottles fitted with a metered atomizer, at 5 mg or 10 mg per unit. This peptide is unusually easy to keep in solution because it is highly hydrophilic and intrinsically disordered, meaning it carries no folded structure to lose and resists the aggregation that troubles more structured peptides. Headspace is nitrogen-purged before capping, and no reconstitution step is required.

Store TB-500 Spray refrigerated at 2°C to 8°C (36°F to 46°F), upright and protected from light, where sealed units remain within specification for up to 24 months. Once the atomizer is first actuated, use the unit within 30 days. Freeze-thaw cycling is less damaging here than for structured peptides, since this sequence is intrinsically disordered and has no fold to disrupt, but repeated cycling still accelerates methionine oxidation. Brief transit excursions to 15°C to 25°C (59°F to 77°F) are tolerated.

TB-500 corresponds to thymosin beta-4, whose primary molecular function is sequestering monomeric actin. It binds G-actin through a short actin-binding motif and holds it in an unpolymerized pool, which sets how much actin is available for filament assembly and therefore governs cytoskeletal remodeling and cell migration. That is a structural mechanism, not receptor agonism, and it separates this compound from essentially every other peptide in a recovery catalog. Research shows additional downstream activity: Bock-Marquette and colleagues reported activation of integrin-linked kinase and Akt signaling, and laboratory investigations describe upregulated laminin-5, increased endothelial cell migration, and reduced inflammatory mediator output.

Yes. Qualified procurement partners can request alternative concentrations, non-standard bottle volumes, unlabeled or private-label presentation, or co-formulation with complementary recovery research compounds such as BPC-157. Contact our corporate sales desk with your target concentration and unit count to scope the run.

Units ship in light-blocking, vacuum-sealed secondary packaging with temperature-stability buffers that hold the shipment inside the refrigerated range through transit. Amber primary containers and nitrogen-purged headspace protect the single methionine residue and the peptide backbone. We ship nationwide across all 50 US states and internationally via express couriers with discrete, border-optimized clearance and full delivery assurance.
