TB-500 Nasal Spray peptide Details
TB-500 Nasal Spray — Research Grade | Pre-Formulated Liquid Solution
This nasal spray formulation delivers TB-500 (Thymosin Beta-4 fragment) as a pre-formulated, sterile liquid solution for research use. No reconstitution is required — the product arrives ready for laboratory application via the nasal spray delivery format.
TB-500 is a synthetic peptide corresponding to the key active region of thymosin beta-4 (Tβ4), a protein naturally found in virtually all human cells. Research has studied its role in actin regulation, cell migration, angiogenesis, wound healing, and tissue repair in preclinical models involving muscle, tendon, ligament, and cardiac tissue.
Nasal spray format note: This product is supplied as a metered-dose nasal spray bottle for research convenience. Transmucosal delivery of thymosin beta-4 fragments has been explored in preclinical research as an alternative delivery modality. All use is strictly for laboratory and research purposes only.
⚠️ For Research Use Only — Not for human consumption. Requires 2nd Day Air or Next Day Air shipping (no ground shipping available).
TB-500 Nasal Spray peptide Scientific Research
1. Cytoskeletal Remodeling
TB-500 regulates the actin cytoskeleton by sequestering G-actin and promoting polymerization into F-actin. This process is essential for changes in cell shape, migration, and structural plasticity.
2. Angiogenesis & Endothelial Cell Function
TB-500 has demonstrated pro-angiogenic properties in vitro and in vivo. It upregulates vascular endothelial growth factor (VEGF) and supports endothelial cell migration and tube formation, which are crucial for neovascularization in tissue repair models.
3. Wound Healing & Epithelial Regeneration
Studies have observed accelerated epithelialization in dermal and corneal injury models, suggesting that TB-500 promotes cell migration and tissue reorganization in healing wounds.
4. Anti-Inflammatory and Oxidative Stress Modulation
TB-500 influences inflammation resolution and cellular responses to oxidative stress, likely via modulation of key transcriptional regulators and cytokine pathways. It’s used in studies investigating systemic and localized tissue stress.
5. Extracellular Matrix & Tissue Remodeling
The peptide plays a role in ECM remodeling by influencing fibroblast activation, collagen deposition, and MMP (matrix metalloproteinase) expression, which are all key elements in soft tissue regeneration.

Handled correctly, stability holds
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
Store vials in a cool, dry place away from heat and direct sunlight.
For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Frequently Asked Questions
PRODUCT & PURITY
This product is offered for laboratory and research use only. It is not intended for human consumption, medical use, therapeutic use, or veterinary use.
Yes, all of our products are sterile and sealed with a sterility plug and safety cap.
Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.
99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.
No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.
Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.
STORAGE & STABILITY
As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.
Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).
SHIPPING
Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
No.
Once your order is processed, you will receive a shipping confirmation email with tracking information.
