TB-500 Peptide (Thymosin Beta-4) Lab Grade Research Peptide — 99%+ Purity

TB-500 is a synthetic peptide extensively studied for its potential applications in tissue regeneration, cellular repair, and molecular biology research. Laboratory studies investigate its mechanisms at the cellular level, including receptor binding, signal transduction, and gene expression pathways. It is widely used in in vitro assays and biochemical profiling.

Reconstitute lyophilized TB-500 using bacteriostatic water. Slowly inject the diluent along the inner wall of the vial. Do not shake vigorously — gentle swirling is preferred. Allow the peptide to dissolve naturally over 1-2 minutes. Once reconstituted, store the solution at 2-8°C and use within 30 days for optimal stability.

When stored properly at -20°C in a sealed container away from direct light and moisture, lyophilized TB-500 remains stable for 24-36 months from the date of manufacture. The expiration date is printed on each vial label. Always check the COA for batch-specific stability data.

Yes. Every batch of CoreVionRX TB-500 undergoes rigorous High-Performance Liquid Chromatography (HPLC) testing to verify purity of 99% or greater. A Certificate of Analysis (COA) is included with each order, documenting the HPLC chromatogram, mass spectrometry data, and batch-specific test results.

CoreVionRX supplies high-purity, lab grade TB-500 directly from our USA-based facility. We offer fast domestic shipping (typically 2-5 business days), discreet packaging, and a 30-day satisfaction guarantee for qualified research applications. All orders ship from within the United States.

CoreVionRX guarantees a minimum purity of 99%+ on all TB-500 batches. This is verified via HPLC and mass spectrometry, with complete results documented on the included Certificate of Analysis. If a batch does not meet this standard, it is rejected and never shipped to customers.

Store lyophilized TB-500 in a freezer at -20°C. Once reconstituted, refrigerate at 2-8°C. Always protect from direct light and moisture. Use within 30 days of reconstitution for optimal stability. Do not freeze reconstituted solution.

TB-500 is supplied as a lyophilized (freeze-dried) powder in a sterile glass vial sealed with a rubber stopper. This form maximizes stability during shipping and enables long-term storage. The powder is reconstituted with bacteriostatic water immediately before laboratory use.

Yes. All CoreVionRX orders are shipped in plain, unmarked packaging with no indication of contents on the exterior. We prioritize your privacy and the security of your research materials. The return address is generic, and no branding appears on the outside of the package.

CoreVionRX offers a 30-day satisfaction guarantee on unopened, properly stored products. Please contact our support team within 30 days of delivery to initiate a return authorization. Items must be in original packaging with the seal intact. Custom or bulk orders may have different return terms.

CoreVionRX supplies lab grade TB-500, which exceeds standard "research grade" definitions. Our peptides undergo more rigorous analytical testing (HPLC + MS), are manufactured under stricter conditions, and come with full documentation. Lab grade is the preferred standard for peer-reviewed research and publication-quality work.

Orders placed before 2:00 PM EST ship the same business day. Standard shipping typically takes 2-5 business days within the continental USA. Express shipping options are available at checkout. You will receive tracking information via email once your TB-500 order ships.
