TB-500Research-Grade Peptide · Lab-Verified Purity
TB-500 is the research market's name for Thymosin β4 — a naturally occurring peptide your body already uses to help cells move to injured areas and repair themselves. It travels systemically, which is why researchers reach for TB-500 when they want whole-body repair effects rather than one localized spot.

Manufacturing, testing, handling, and shipping details for TB-500. For research purposes only — not for human or animal consumption.
TB-500 — Product Overview
TB-500 is the research market's name for Thymosin β4 — a naturally occurring peptide your body already uses to help cells move to injured areas and repair themselves. It travels systemically, which is why researchers reach for TB-500 when they want whole-body repair effects rather than one localized spot.
TB-500 — Molecular Characteristics & Vial Specifications
ProSource Labs supplies TB-500 in the following available vial sizes: 10mg. Each TB-500 vial contains pure lyophilized peptide — no fillers, no bulking agents. Product SKU references: TB5-10MV.
- Systemic Repair: Moves through the body to support widespread muscle and tissue recovery
- Cell Migration: Encourages cells to travel to injury sites for faster wound closure
- Less Scarring: Studied for reducing fibrous scar-tissue formation during healing
- Pairs Well: Standard partner peptide to BPC-157 in the 'Wolverine' repair stack
Batches are characterized by ESI mass spectrometry to confirm molecular weight against the theoretical value, with amino-acid sequence confirmation on selected QA lots. Peptide content assay distinguishes net peptide mass from residual counter-ion salt.
TB-500 — Laboratory Handling & Storage
Lyophilized TB-500 vials should be stored at -20°C (or colder) in a laboratory freezer, inside the sealed factory container. Minimize warm-up cycles — move only the specific vial needed for a given experiment out of frozen storage at a time.
All laboratory handling of TB-500 should follow the receiving institution's SOPs and applicable peer-reviewed protocols relevant to the researcher's specific experimental question. ProSource Labs does not publish end-user preparation or usage instructions.
TB-500 — Third-Party Analytical Testing
Every batch of TB-500 released by ProSource Labs undergoes independent reverse-phase High Performance Liquid Chromatography (HPLC) — the industry-standard analytical method for this class of research compound. Target chromatographic purity is typically ≥ 99%.
Additional characterization may include ESI mass spectrometry for molecular weight confirmation, Karl Fischer titration for residual moisture, and appearance/solubility inspection. A batch-specific Certificate of Analysis (COA) is available on request through customer support after purchase.
TB-500 — Quality Assurance Process
Each production lot of TB-500 is quarantined pending analytical release, tested against documented purity, identity, and moisture acceptance criteria, and only released to sellable inventory after passing every QA checkpoint. Batches that fail any single criterion are quarantined and never reach customer-facing inventory.
If a vial of TB-500 you received from ProSource Labs ever fails your own institution's incoming QA testing, contact customer support at support@prosourcelabs.org — we retain samples of every batch for cross-verification.
TB-500 — Typical Research Application
Common in research studies on cell migration, wound closure, cardiac ischemia recovery, corneal repair, and hair-follicle activation. Frequently combined with BPC-157 in the classic "Wolverine stack" for complementary localized + systemic repair coverage.
TB-500 — Packaging & Fast Southern California Shipping
TB-500 vials ship in tamper-evident, moisture-resistant, cold-chain-friendly outer packaging from our Southern California distribution facility for fast US domestic delivery — typically 2-4 business days coast-to-coast, with expedited options available at checkout.
Every TB-500 shipment is discreet — the outer packaging carries no product-specific branding or direct reference to the compound name inside, protecting researcher privacy. Tracking numbers are emailed automatically. For institutional or high-volume orders, dedicated wholesale pricing is available through the wholesale portal.
